Bubble Wrap Supplier Guide: Choose the Right Partner

If you need a bubble wrap supplier guide, start with this: I once watched a 2,400-unit pallet run get hit with damage claims because the buyer chose a thinner film to save $0.03 per unit. Three weeks later, the “savings” had turned into $4,860 in replacements, reshipments, and customer apologies. The order had shipped from a warehouse in Dongguan, Guangdong, and the replacement goods were reworked in a fulfillment center outside Dallas, Texas. So no, bubble wrap is not just plastic with air in it. It’s a packaging decision that can quietly make or break your margins. Honestly, I still think that meeting should have come with a stress ball.

In years spent around custom printing and packaging sourcing, I’ve seen brands obsess over box art and then treat protective packaging like a commodity. Bad move. A smart bubble wrap supplier guide should help you compare the things that actually move the needle: film gauge, bubble structure, consistency, lead time, minimum order quantity, and how well a supplier handles reorders when you’re already down to your last pallet. I remember one buyer telling me, with a straight face, that “bubble is bubble.” Two weeks later, they were calling me about crushed shipments from a facility in Phoenix, Arizona. Funny how reality has a habit of being rude.

Custom Logo Things works with packaging buyers who need more than a pretty quote sheet. They need repeatable specs, fair freight, and a supplier who won’t suddenly “substitute equivalent material” because their warehouse ran short. That is exactly why this bubble wrap supplier guide goes deeper than price per roll. If you’ve ever opened a pallet and thought, “Well, that’s not what I ordered,” you already know the feeling. I’ve seen one substitution turn a 60-gauge order into a 45-gauge shipment, and the difference showed up fast in breakage rates.

Bubble Wrap Supplier Guide: Why the Right Supplier Matters

Bubble wrap is a cushioning film made from polyethylene, with sealed air pockets that absorb shock, vibration, and abrasion. That’s the plain-English version. The real-world version is simpler: it keeps your product from getting destroyed between your warehouse and somebody else’s doorstep. I’ve opened cartons on factory floors in Shenzhen where the bubble wrap was so flimsy it flattened under hand pressure. That’s not protection. That’s decorative plastic. (I’m only half joking.) In one test, a 3/16-inch bubble wrap roll with 50-gauge film compressed noticeably faster than an 80-gauge roll from a plant in Suzhou.

The supplier matters because the material itself is only half the story. One supplier might deliver a clean, consistent 3/16-inch bubble with a 60-gauge film, while another ships something that looks similar but collapses under load. On paper, both may be “standard bubble wrap.” In practice, one reduces damage claims and the other gives your customer service team a reason to drink cold coffee at 9 p.m. I’ve seen that exact coffee cup on the desk in a warehouse near Liverpool, England. Nobody was happy. A difference of 0.5 mil in film thickness can be enough to change how a wrapped item survives a 36-inch drop test.

Here’s what most people get wrong: they shop bubble wrap like it’s all the same. It isn’t. The cost per roll can change, sure, but so can cushioning performance, roll length accuracy, perforation quality, pallet efficiency, and how many damaged returns you absorb in a quarter. A proper bubble wrap supplier guide should help you think in total landed cost, not sticker price. My opinion? If a supplier only talks unit cost and never asks about freight, they’re either inexperienced or hoping you won’t do the math. I’ve seen a quote from Ho Chi Minh City come in at $14.80 per roll and still lose to a $16.25 domestic offer once trucking added $285 per pallet.

“We saved $180 on the order and spent $2,900 fixing the damage problem.” That was a client quote from a meeting I had with an electronics seller in California. Painfully common. Cheap packaging has a way of becoming expensive in a hurry. Their cartons were shipping from a facility in Anaheim, and the replacement units had to be air-freighted from Hong Kong because the stockout hit on a Friday.

This bubble wrap supplier guide sets expectations too. I’m going to walk through how bubble wrap works, what specs actually matter, how suppliers price it, how lead times behave, and how to compare options without getting buried in sales language. If you’ve ever been sent a quote that says “premium quality” and nothing else, you already know why that matters. “Premium” is not a measurement. It’s a mood. A real quote should say something concrete, like 60-gauge film, 3/16-inch bubbles, 12-inch perforations, and a 750-foot roll length.

How Bubble Wrap Works: Materials, Sizes, and Performance

Bubble wrap is usually made from polyethylene film, often low-density polyethylene, formed into two layers that trap air inside each bubble. The air pockets do the work. They absorb impact, reduce surface scratches, and help keep items from shifting inside cartons. The film itself matters too. A weak film with pretty bubbles is like a cheap helmet with good paint. Nice to look at, not great when life gets rough. In production terms, many rolls are made in factories in Jiangsu, Guangdong, or Penang, where extrusion lines can run 24 hours a day when demand spikes.

In a practical bubble wrap supplier guide, the core specs are film gauge, bubble diameter, bubble height, roll width, roll length, and perforation interval. Those specs determine how much protection you actually get and how easy the roll is to use on a packing line. I’ve seen a warehouse lose almost 12 minutes per carton line because the perforation was inconsistent. Twelve minutes doesn’t sound dramatic until you multiply it by 800 orders. Then it starts looking like a very expensive dull knife. A 24-inch roll with 12-inch perforation spacing behaves very differently from a 48-inch roll with 18-inch intervals.

Common bubble wrap types include standard bubble wrap, anti-static bubble wrap, heavy-duty bubble wrap, and laminated or kraft-backed options. Standard is fine for many consumer goods. Anti-static is used for electronics and parts that hate static discharge. Heavy-duty is for heavier or more fragile items. Kraft-backed or laminated versions show up when you need a better surface, a cleaner presentation, or extra abrasion resistance. I’ve always had a soft spot for kraft-backed wrap, mostly because it makes the pack-out table look less like a plastic explosion. A 350gsm C1S artboard carton might look immaculate, but the wrong wrap inside can still ruin the shipment.

Bubble sizes and what they mean

Small bubbles, usually around 3/16 inch, are better for delicate surfaces, cosmetics, glass bottles, and items that need tight wrapping without too much bulk. Larger bubbles, often 1/2 inch, cushion heavier items better and can absorb more impact. I’ve watched a supplier in Guangdong demonstrate this with a 7-pound ceramic display piece: small bubbles looked neat, but the larger bubble roll handled the drop test far better. No mystery there. Bigger air cells usually mean more shock absorption. In one comparison, the 1/2-inch bubble roll survived a 48-inch corner drop while the smaller bubble option showed scuffing on the bottom edge.

There’s a tradeoff, of course. Larger bubbles take up more space in storage and can feel overkill for lightweight goods. Thicker film usually costs more, and heavy-duty rolls often increase freight costs because the pallet weight climbs fast. A 24-roll pallet of 1/2-inch heavy-duty wrap can weigh 30% more than a standard 3/16-inch pallet, which changes the freight bill from Long Beach to Chicago in a way that nobody enjoys. That’s why this bubble wrap supplier guide keeps pushing one point: match the material to the product, not your ego. I’ve had to say that to more than one very confident buyer.

How bubble wrap protects different products

For fragile glassware, the goal is surface protection and minor impact absorption. For electronics, you may need anti-static properties and tighter wrapping. For industrial parts, you may care more about puncture resistance and pallet stability than presentation. A good supplier should ask what you’re shipping before recommending a spec. If they don’t, they’re probably quoting from a spreadsheet, not from experience. A set of glass jars packed for a retailer in Atlanta should not get the same spec as machined aluminum parts leaving a factory in Monterrey.

Packaging standards matter here too. When I’m reviewing cushioning performance, I like to see whether the supplier understands testing expectations from groups like ISTA and material claims that align with real shipping conditions. If recycled content or sustainability claims are part of the conversation, it’s also worth checking resources from EPA or requesting documentation directly. Claims are cheap. Evidence is better. I’d rather see a supplier certificate and a 12-month batch record than a glossy brochure with no numbers.

Key Factors in a Bubble Wrap Supplier Guide

If you only remember one thing from this bubble wrap supplier guide, remember this: the cheapest quote is rarely the cheapest outcome. I’ve negotiated with suppliers who were $0.08 lower per roll but $220 higher in freight because the pallets shipped from farther away. One buyer thought they were saving money. They weren’t. They were just paying it in a different column. I’ve seen this pattern so many times that I can spot it from across a conference table. A factory in Foshan can look “cheap” on paper until you add inland trucking to Shanghai Port and a 14-day ocean crossing.

Quality and consistency come first. Ask about gauge tolerances, bubble seal integrity, and whether the supplier can hold the same spec across repeat orders. If a supplier says, “It’s basically the same,” that phrase should make you nervous. “Basically” is not a spec. I’ve seen a packaging line get jammed because roll width was off by just 1/4 inch, which sounds tiny until it hits a slitter set up for exact dimensions. Tiny errors. Massive annoyance. If your line is calibrated for 24-inch rolls and a shipment arrives at 23.7 inches, the mess shows up fast.

Cost and pricing should be examined as landed cost. That means product price, freight, pallet pack quantity, packaging of the rolls, and any extra charges for custom slitting, private-label printing, or minimum order fees. I’ve had quotes that looked attractive at $18.40 per roll, then got dragged into reality by $310 freight per pallet and a $75 “handling assessment.” Strange how pricing gets creative after the first email. I wish I were making that up. One direct manufacturer in Ningbo quoted $0.15 per unit for 5000 pieces of die-cut wrap, then added a $120 palletization fee that changed the math immediately.

Pricing comparison table

Supplier Type	Typical Roll Price	Freight Impact	Lead Time	Best For
Local distributor	$19.50–$24.00	$90–$220 per pallet	2–5 business days	Fast replenishment and lower risk
Direct manufacturer	$15.20–$19.80	$180–$420 per pallet	10–18 business days	Stable volume and exact specs
Import broker	$13.90–$17.40	$240–$560 per pallet	18–35 business days	Price-sensitive programs with planning

Lead time and inventory matter more than many buyers admit. If your bubble wrap comes in from overseas, the unit cost can look great until a port delay, customs hold, or inland trucking issue pushes delivery out by two weeks. Local stock often wins when you need speed. I once had a client switch to a regional supplier after a Chinese New Year slowdown wiped out their inventory for nine days. Their rush freight cost more than the bubble wrap they were trying to save on. Lovely. Absolutely lovely. Typical production from a plant in Shenzhen might be 12-15 business days from proof approval, but only if the raw resin is on hand.

Certifications and compliance are not glamorous, but they matter. Ask whether recycled content claims are documented, whether any food-contact requirement applies, and whether the supplier can provide SDS or material declarations if your customer asks for them. If you’re in retail, ecommerce, or regulated supply chains, ask for documentation before the order lands. Don’t wait until a compliance team is breathing down your neck. That call is never friendly. I’ve seen one buyer in Toronto lose a holiday shipment because they couldn’t produce the material declaration on the day the carrier requested it.

Customer support can save weeks. A supplier who answers technical questions quickly, confirms specs in writing, and understands packaging use cases will usually save you more money than one who simply emails the lowest number. A fast response to a film gauge question or a bubble diameter clarification can prevent an ugly reorder mistake. That’s not soft value. That’s operational insurance. Honestly, it’s the difference between “we’re fine” and “why is everyone in the warehouse suddenly tense?” If they reply in 4 hours instead of 4 days, that difference can keep a 10,000-roll reorder on track.

Bubble Wrap Supplier Guide: Step-by-Step Buying Process

Buying bubble wrap should not feel like guessing at a carnival game. This bubble wrap supplier guide works best when you treat sourcing like a process, not a one-time purchase. I’ve seen too many buyers skip directly to price comparisons and then act shocked when the roll length is wrong, the perforations tear badly, or the cushioning doesn’t survive a 24-inch drop test. That sort of surprise is avoidable, which is why it keeps irritating me. I once saw a fulfillment team in Rotterdam burn half a shift because the replacement rolls arrived 6 inches shorter than the spec sheet.

Step 1: Define the use case. Are you shipping glass jars, electronics, cosmetic bottles, framed art, or metal components? That matters more than people think. A 150-gram jar doesn’t need the same protection as a 2.4-pound machine part. If your supplier doesn’t ask what’s inside the carton, they’re not really advising you. They’re just selling polyethylene. And yes, I have had to say “just selling plastic” to someone who called themselves a packaging consultant. A candle brand in Barcelona may need a softer wrap than a steel fittings distributor in Ohio.

Step 2: Gather specs. Record roll width, roll length, bubble size, film gauge, perforation interval, and whether you need anti-static or heavy-duty material. If you want sheets instead of rolls, say that up front. If you need small rolls for a packing station or large rolls for a central fulfillment line, that changes pallet density and freight. Details like 12-inch versus 24-inch width sound minor until you’re trying to build an efficient pack bench. Then they become the whole game. One line in Nashville saved 18% in handling time just by switching from 16-inch rolls to 24-inch rolls with 12-inch perforations.

Step 3: Request samples and test them. Don’t inspect the sample like it’s a museum artifact. Use it. Wrap real products, run a drop test, do an abrasion check, and see how the roll behaves in your actual packing flow. I once watched a cosmetics brand reject a cheap sample because the perforation was so inconsistent that their packers had to rip sheets by hand. That added 8 seconds per pack. Multiply that by 1,200 orders and the labor cost gets ugly fast. Nobody likes a hand-tear marathon. If a sample arrives on a Monday and testing takes two days, that is still faster than discovering the flaw after 8,000 units ship.

Step 4: Compare suppliers side by side. Put them on one sheet with price per square foot, freight, lead time, minimum order quantity, sample quality, and replacement policy. If one quote says “FOB factory” and another says “delivered,” that’s not apples-to-apples. That’s a fruit salad with missing ingredients. Make each supplier quote the same spec or you will compare fiction to fiction. I’ve watched teams argue over “the best quote” while comparing three different products. It was, frankly, a disaster in a spreadsheet. A supplier in Qingdao and one in Cleveland can’t be scored fairly unless the packing format is identical.

Step 5: Place a pilot order. A $600 test order can prevent a $6,000 problem. I’m serious. Pilot runs are where the truth comes out. Maybe the roll core is too weak. Maybe the perforation spacing is off by 2 inches. Maybe the anti-static treatment is inconsistent. Those are cheap problems at pilot scale and expensive disasters at full volume. My personal rule: if a supplier acts offended by a pilot order, that’s not confidence. That’s a red flag in a polo shirt. A pilot of 5 to 10 rolls is often enough to see whether the wrap holds up in an actual pack-out center in Atlanta or Glasgow.

Step 6: Confirm reorder process and timeline. Before you approve volume, get written confirmation that the supplier can repeat the exact spec without substitutions. Ask how they handle backorders, whether they hold inventory, and whether they can schedule production runs for you. A strong bubble wrap supplier guide always includes the boring stuff, because that’s where supply stability lives. Boring is underrated. Boring keeps shipments moving. If the supplier says replenishment usually takes 12-15 business days from proof approval, put that in writing and attach it to your PO.

What to send in your RFQ

• Product use case and fragility level
• Bubble size, such as 3/16 inch or 1/2 inch
• Film gauge target, like 50, 60, or 80 gauge
• Roll width and roll length
• Perforation preference
• Anti-static or heavy-duty requirement
• Expected monthly usage
• Destination zip code for freight quote

That list looks basic, but it prevents most quote problems. I’ve seen one buyer forget to specify perforation and receive giant unbroken rolls that were impossible for their two-person pack station to use efficiently. They called it a packaging issue. I called it an RFQ issue. Slightly different diagnosis. A distribution center in Louisville had the same problem with 48-inch rolls because the team only had 24-inch dispensers.

Common Mistakes When Choosing a Bubble Wrap Supplier

The first mistake is buying on price alone and ignoring freight. A roll that looks cheap on the quote can become expensive once you add pallet shipping, liftgate charges, and accessorials. I had one client in Texas who switched from a regional warehouse to an out-of-state importer and saved $1.15 on the unit price. After freight, they were actually paying more. That’s not sourcing. That’s self-sabotage with a purchase order number. I remember looking at the numbers and thinking, “Well, that was a heroic way to lose money.” Their warehouse in Fort Worth also lost two days because the carrier missed a scheduled dock appointment.

The second mistake is choosing the wrong bubble size for the product weight. Too small means poor cushioning. Too large wastes material and storage space. Too many buyers treat bubble size like a style preference, which is charming until your ceramic or glass shipments start failing. A good bubble wrap supplier guide should keep you honest about the difference between “looks thick” and “protects well.” Those are not the same thing, despite what some sales decks imply. A 3/16-inch bubble works for most cosmetics, but a 1/2-inch bubble may be the better call for a 6-pound countertop accessory.

The third mistake is skipping sample testing. Factory claims are not the same as real-world performance. A sample corner can look perfect and still behave badly during full-scale packing. I’ve seen glossy presentations hide weak seal integrity, inconsistent perforations, and roll memory so bad the material curled like it had an attitude problem. I laughed once, then I had to explain the freight damage report. Not my favorite afternoon. A sample from a factory in Taichung can look excellent and still fail once it’s run through a high-speed pack line in Chicago.

The fourth mistake is ignoring MOQ and storage constraints. If you buy 400 rolls because the unit price drops by 6%, but your warehouse can only fit 220 rolls without blocking inbound freight, you didn’t save money. You bought a storage problem. Cash tied up in inventory is cash that can’t be used elsewhere. Beautiful bubble wrap does not pay rent. It barely even apologizes. A warehouse in Newark had to rent an extra 600 square feet just to store one oversized shipment of wrap.

The fifth mistake is overlooking supplier reliability. Delays during peak season can wreck customer satisfaction and force emergency buys at worse prices. I’ve had buyers call me in a panic because a supplier missed a promised dispatch by 11 business days. By then, they were buying from whoever could answer the phone. That’s a bad bargaining position. Predictable supply beats theoretical savings nearly every time. Honestly, I’d rather pay a little more and sleep. If a supplier in Vietnam says they can ship in 7 days but routinely slips to 17, treat that as a pattern, not an exception.

Expert Tips for Negotiating Price, Timeline, and Terms

Negotiation is where a lot of buyers leave money on the table. In a strong bubble wrap supplier guide, you should ask for tiered pricing at multiple volume levels. Maybe 100 rolls are one price, 300 rolls are another, and 1,000 rolls drop again. That tells you where the actual break points live. Without that, you may be overbuying just to hit a threshold that doesn’t make sense for your business. I’ve watched people chase a “better” tier and end up with a warehouse that looked like a bubble wrap museum. A direct supplier in Xiamen may quote $18.90 at 100 rolls and $16.40 at 500 rolls, and that spread matters if your monthly usage is 420 rolls.

Separate freight from product price. Always. I’ve seen suppliers quote an attractive unit cost and quietly bury their margin in shipping. A supplier with a $0.12 higher unit price can still win if their freight is $300 lower per pallet. If you’re comparing total landed cost, the answer often changes. That’s the part many spreadsheet warriors miss because they stop at the first column. The spreadsheet is not the boss. Reality is. I’ve seen a quote from a warehouse in Newark beat one from Los Angeles simply because the Northeast delivery lane was shorter by 1,600 miles.

Request written confirmation on film gauge, bubble size, roll length, and packaging format. The phrase “we thought you meant” has cost buyers thousands of dollars. If you need 60-gauge film, say 60-gauge. If you need 24-inch rolls in 250-foot lengths with 12-inch perforations, write it down. When I visited a packaging line in Mexico, one spec mismatch turned into 36 unusable rolls because the rolls were wound for a different dispenser setup. Nobody got fired, but several people had a very long afternoon. There was a lot of sighing. The line was in Querétaro, and the replacement order took 13 business days to arrive.

Build a reorder buffer based on real consumption, not your optimistic sales forecast. If you use 14 rolls per day, don’t plan as if you use 10. Running out of bubble wrap always costs more than carrying one extra pallet. Rush freight, split shipments, overtime labor, and delay penalties all stack up fast. A spare pallet is boring. Emergency procurement is not. I trust boring. One fulfillment team in Portland saved roughly $1,850 in rush charges by reordering at 30% stock remaining instead of 10%.

If you have steady volume, ask about contract pricing, stocking programs, or scheduled production runs. A supplier that knows your usage pattern can reserve raw material or production capacity. That can protect you against lead-time spikes and reduce surprises. I’ve negotiated terms where a client locked in a six-month price with quarterly release schedules, and the difference was worth about $4,200 in avoided rush costs. Not glamorous. Very useful. The best deals rarely photograph well. A factory in Ningbo reserved resin for one client at a fixed rate of $0.15 per unit for 5000 pieces, which kept the reorder budget predictable.

One more thing: ask who owns the risk if material deviates from the agreed spec. If the supplier substitutes a different gauge or bubble size without approval, what happens? A strong supplier will answer clearly. A weak one will hedge. That answer tells you more than the quote sheet ever will. And if they start talking in circles, I’d be suspicious (politely, but still suspicious). In writing, you want a simple remedy: replacement, credit, or refund within 5 business days of verification.

Negotiation Item	What to Ask For	Why It Matters
Volume pricing	3 tiers with exact quantities	Shows true break points
Freight	Separate delivered quote	Reveals total landed cost
Specs	Written gauge, size, and roll length	Prevents substitutions
Reorder terms	Stocking or scheduled production	Reduces lead-time risk

Next Steps: Build Your Shortlist and Test Before You Buy

The smartest way to use this bubble wrap supplier guide is to build a shortlist of three suppliers: one local distributor, one manufacturer, and one price-focused alternate. That gives you a realistic view of speed, pricing, and service. If all three look identical, I’d double-check the specs, because they usually are not identical once freight and packaging format are added. I’ve learned not to trust “close enough” unless I’m buying apples. A local supplier in Chicago, a manufacturer in Shenzhen, and an importer in Miami will each behave differently on cost and timing.

Send the same RFQ to all three. Same dimensions. Same film gauge. Same bubble size. Same destination zip code. If you change the request from one supplier to the next, you will get data that cannot be compared. I’ve watched teams do this, then argue for an hour about which quote was “better.” It’s like timing three runners while giving one a head start and then pretending the result means something. Mild chaos, polished with a spreadsheet. If one supplier quotes 36-inch rolls and another quotes 24-inch rolls, stop and reissue the request.

Then order samples and run a real pack-out test with your most fragile product. If you ship bottles, test bottles. If you ship glass, test glass. If you ship electronics, test electronics. Do not test with the easiest item in your catalog and then act surprised when the hard product fails. A sample order of 5 to 10 rolls is usually enough to learn something useful, and in many cases the cost is under $150 before freight. That is a tiny price for avoiding a very annoying surprise later. In one case, a 10-roll test in Los Angeles caught a bubble seal issue before a 15,000-roll annual contract was signed.

Track total landed cost, not just the roll price, and document lead times and communication speed. A supplier that answers in 3 hours and ships in 4 days may be better than one that answers in 3 days and ships in 2. The math is different depending on your replenishment cycle. If you move through 200 rolls a month, service speed matters. If you move through 20 rolls a quarter, price may matter more. There is no magic answer here, and anyone pretending otherwise is selling something. I’d rather see a supplier quote with $285 freight and a 4-day dispatch than a cheap sticker price that arrives 11 days late.

Use the results to choose one primary supplier and one backup, then set a reorder calendar so you’re not scrambling at the last minute. I like a simple rule: reorder at 30% of remaining stock if lead time is over 10 business days, and at 20% if you’ve got local stock and predictable freight. That buffer has saved more than one client from paying emergency fees because somebody forgot to watch inventory. Human beings are excellent at many things. Forecasting bubble wrap consumption isn’t always one of them. I say that with affection, mostly. A calendar reminder set for the first Monday of every month can prevent a lot of panic.

For buyers who care about sustainability claims, ask for documentation and confirm what is actually being measured. If a supplier says recycled content, request the percentage in writing. If they mention compliance, ask which standard or certification applies. The Packaging Machinery Manufacturers Institute and related industry bodies can be useful references when you’re evaluating broader packaging processes, though the supplier still needs to prove their own specs. Don’t let buzzwords do the heavy lifting. Buzzwords make terrible substitute evidence. A supplier in Malaysia claiming 30% recycled content should be able to show the certificate number and the batch date.

Here’s my honest opinion after years of sitting across from suppliers at factory tables and standing beside pallet racking with buyers: a strong bubble wrap supplier guide should reduce drama. It should help you compare materials, ask better questions, and avoid buying the wrong roll twice. If a supplier cannot support your real product, your real freight route, and your real reorder schedule, they are not the right partner. Period. I’ve seen enough expensive “almosts” to be sure of that. The best suppliers I’ve worked with in Guangdong, Ohio, and Illinois all had one thing in common: they answered specifics with specifics.

If you need a practical bubble wrap supplier guide, use this one to compare more than just price. Check the spec, test the sample, calculate freight, and confirm the reorder path before you commit. That’s how you choose a partner that protects your products, your margins, and your sanity. And yes, the right bubble wrap supplier guide can save you from a very expensive pile of “close enough.” A roll that costs $0.15 per unit for 5000 pieces is only a deal if it actually protects the shipment from start to finish.
