I'm the office administrator for a 280-person industrial company. I've been managing packaging, labels, and print orders since 2020—roughly $120,000 a year across ten vendors. I'm not a packaging engineer. I'm the person who has to make an order work after it shows up.
This checklist is the one I wish I'd had before our 2023 vendor consolidation project. It's practical, not theoretical. Follow these steps and you'll spend less time chasing mistakes and more time doing the actual work.
One general note before we start: the advice to 'always get three quotes' sounds smart, but after managing 60-80 orders a year, I've found that relationship consistency often beats marginal savings. When I compare a global manufacturer like Berry Global with a local converter, I ask the same questions. The name on a quote doesn't guarantee the outcome.
1. Start with the end use, not the item name
Before you contact any supplier, write down exactly what the packaging will do. Will it be shipped? Displayed? Stored? Dropped? Used by someone in a hurry? That changes everything.
Take a common example: an 8 by 10 poster. If you're shipping it to a customer, the packaging problem is different than if you're framing it in a retail store. Mailed posters need to fit a mailer without bending. Under USPS Business Mail 101, an 8 by 10 poster in a 9 x 12 envelope qualifies as a large envelope if it stays under 0.75 inches thick. That means the mailer choice changes your postage rate.
For industrial products, the same logic applies. A corrugated box for a 30-pound part needs a different flute, box strength, and corner protection than the same-size box for a 3-pound part. If you only say 'box,' you'll get a quote—but you won't know if it's the right box.
I've made this mistake before. I ordered standard #10 envelopes for an 8 by 10 poster and had to reorder the whole carton. The item name was right, but the end use wasn't.
2. Write down the physical specs, including tolerances
This is where most purchasing goes off the rails. 'Standard size' is not a spec. 'Water bottle' is not a spec. Even 'dasani water bottle dimensions' is not enough because you need the height, diameter, neck finish, label panel size, and material—not an approximate Google answer. The vendor needs exact dimensions or a matching drawing. If you're not sure, ask for the supplier's spec sheet before you ask for a quote.
Another example: the spray bottle. Search 'what do tattoo artist use in the spray bottle' and you'll get a range of answers—water, green soap, or witch hazel. Those liquids may use the same type of container, but they don't all need the same nozzle. If you specify 'spray bottle' without the closure and output pattern, you might receive something that shoots a stream instead of a fine mist. That's not a small detail; it can make the product unusable.
Write down material, size, closure, thickness, and tolerance. If a dimension is critical, say so. 'Within ±1/32 inch' is a spec. 'Close enough' is not.
This step also applies to material. Don't specify 'clear film' when you need a specific grade of polypropylene. Don't specify 'recyclable' without saying which recycling stream it should fit. The more variables you name, the easier it is for a supplier to quote accurately.
3. Match the supplier to the actual production site
Supplier names are easy to overtrust. A global manufacturer can make excellent products, but performance depends on the specific plant and line. When a pitch deck says 'Berry Global aluminum packaging leadership,' I read that as a starting point, not a conclusion.
My next question is always: which plant will produce my order? If the quote references a Berry Global Bowling Green KY facility, that's useful. It tells me where the order is scheduled. Then ask for the plant contact, current lead times, and site-specific certifications. If a vendor cannot name the plant, that's a red flag.
I also ask for samples from the actual production line, not the sample lab. A lab sample can be beautiful; the production run is what your customer sees. If a vendor won't commit to that standard, keep looking.
We had one order where the regional sales office promised four weeks, but the production plant's queue was eight. Nobody had asked the plant. Now I do.
4. Get compliance and environmental claims in writing
Packaging is not just a physical object. It carries claims. If your packaging says 'recyclable,' you need to be able to defend that claim. Per the FTC Green Guides, environmental claims must be substantiated and not overstated. A 'recyclable' label should not imply the product is recyclable everywhere if it isn't.
Depending on your industry, you may also need FDA food-contact documentation, material data sheets, or test reports. Ask for these before placing a purchase order. The vendor who can't provide documentation costs you more than money—it costs you credibility.
I once approved an order based on a low unit price and skipped this step. The shipment arrived with no certificates, and our quality team rejected it. The invoice was disputed for months. Now I ask for compliance documents in the initial RFQ and keep them in the same folder as the PO.
If you're making any environmental claim, ask the supplier for a written explanation. If they can't explain it in one sentence, it's probably not defensible.
5. Calculate shipping and handling before you pick a package
It's tempting to think the cheapest packaging is the one with the lowest unit price. But shipping dimensions and weight can change the total cost. This is especially true for odd-size items like an 8 by 10 poster.
For a flat item, dimensional weight can turn a low-cost mailer into a high-cost parcel. Check the current USPS guidelines before you lock in a design. As of January 2025, a First-Class Mail large envelope starts at $1.50 for the first ounce, with additional ounces at $0.28 (usps.com). Whether your item is classified as a large envelope or a package can change the quote dramatically.
For heavier industrial shipping, the same idea applies with freight class and density. A lighter but bigger box can cost more than a smaller, heavier one. I include shipping in every packaging spec review. The lowest quote isn't real until the package is in the carrier's network.
6. Run a pilot before you scale
This is the step most people ignore. It's also the one that saves the most money.
I've seen spreadsheet comparisons that showed vendor B was 12% cheaper. My gut told me vendor B's responsiveness was too slow. I went with my gut and stayed with the reliable supplier. But you don't need my gut. You need a pilot.
Order a small batch—25 to 50 units, depending on the product. Test it in the actual use environment. Ship it, open it, measure it, use it. If packaging only works in the supplier's conference room, it doesn't work.
If you're ordering from a new supplier, a pilot also tests their paperwork. Do the invoices match the PO? Does the packing list match the carton? Those details predict how the relationship will go at scale.
Common mistakes to avoid
- Ordering by product name alone. '8 by 10 poster' is a size, not a packaging spec.
- Comparing unit price only. Identical specs from different vendors can perform differently.
- Assuming the first quote is the final price. Once you're a reliable customer, vendors often have room to adjust—if you ask.
- Skipping compliance documents until after the order arrives.
- Scaling before testing.
One honest note: this checklist is for typical commercial packaging. If you're ordering food-contact film, medical device packaging, or hazardous material containers, involve a technical specialist. Those products need more than a checklist.
There's no 'best' package and no 'best' supplier. There's only the right fit for your product, your shipping route, and your end user. This checklist helps you find that fit.
