What Nobody Tells You About Packaging Procurement: A 5-Step Sanity Check

I manage procurement for a mid-sized manufacturing company—about 400 employees across three facilities. I oversee roughly $400K annually in packaging, across maybe 8 vendors depending on the product. When I took over purchasing in 2020, I inherited a binder full of handwritten invoices and a VP who had 'strong opinions' about Chep pallet pricing. I learned the hard way that packaging procurement isn't just about finding the cheapest drum or the best price on bubble wrap. It's about knowing what you actually need, verifying the supplier can deliver it, and making sure Finance doesn't reject your report two months later.

This checklist is for anyone who manages industrial packaging orders—drums, IBCs, corrugated, containerboard, or even that roll of 24" bubble wrap that someone always forgets to reorder. If you're just looking for the lowest price on greif packaging, this won't help. If you want to avoid the invoice rejection, the delivery delay, or the meeting where you explain why the supplier sent 55-gallon drums when you needed 30-gallon, read on.

Here are the 5 steps I now follow for every packaging order.

Step 1: Translate the Internal Request into a Real Requirement

This step catches 90% of my potential mistakes. The request that lands on your desk is almost always incomplete. Someone says 'we need 100 steel drums,' but what they really mean is 'we need 100 steel drums that can hold a specific chemical, with a specific lining, delivered to a specific dock by a specific date.' The gap between those two statements is where problems live.

I now have a short checklist I run through before I even touch a vendor. The third time we ordered the wrong quantity, I finally created a verification process. Should have done it after the first time.

• What material? Steel, plastic, fiber? UN-rated for hazardous materials or just for general storage?
• What size? 55-gallon, 30-gallon, 20-liter? IBCs?
• What closure? Open head or tight head? Lever lock or bolt ring?
• What lining? Phenolic, epoxy, polyketone? Or just plain carbon steel?
• What quantity? And is it a one-time order or a recurring purchase?
• When do they actually need it? Deadline is different from the 'would be nice' date.

Hard stop: If the requester says 'just get me whatever greif packaging llc has in stock,' I push back. I want a UN specification if applicable. I want a lining spec. I want a delivery window. 'Whatever' is how you end up with the wrong container.

Step 2: Evaluate Total Cost, Not Unit Price

Our accounting team rejected a vendor expense report once because the vendor couldn't produce a proper invoice—handwritten receipt only. That was a $2,400 hit to my department budget. Now I verify invoicing capability before placing any order. Seriously, that was a stupid mistake and I'm still annoyed about it.

When you evaluate packaging suppliers, especially for large orders like drums or containerboard from a company like Greif or any other industrial packaging supplier, the unit price is only the beginning. Here's what I calculate now:

• Unit price (obviously)
• Shipping and handling – full truckload vs. less-than-truckload? That changes the cost significantly.
• Setup or tooling fees – for custom printing or unique closures
• Rush charges – if you need it faster than standard turnaround
• Payment terms – net 30 vs. net 60 vs. credit card surcharges (are business credit card payments tax deductible? Sometimes yes, sometimes no—check with your accountant)
• Return and defect policy – what happens if the drum arrives dented?

I've seen requests go through where the unit price was amazing but the shipping doubled the total. Way more than I expected. Now I get a total landed cost before I approve anything.

Line-of-sight: Package weight + pallet dimensions + class → rate. If the supplier can't give you a shipping estimate, that's a red flag.

Step 3: Verify the Supplier Can Actually Deliver—Before You Commit

This is the step most people skip. I've had three different vendors promise a 2-week lead time on UN-rated steel drums, only to call back a week later and say 'sorry, the raw material is on backorder.' Now I ask specific questions up front:

• Current stock levels – How many drums are on the floor right now?
• Lead time for custom orders – If we need a special lining or printing, how long does that add?
• Recent delivery performance – I ask for a reference from a customer who ordered similar volume in the last 6 months. If they can't provide one, I'm skeptical.
• Contingency plan – If their supplier fails, what's their backup?

I also ask about their invoicing system. The vendor who couldn't provide proper invoicing cost me $2,400 in rejected expenses. Now I verify invoicing capability before placing any order.

I'll be honest: I've only worked with domestic vendors so far. I can't speak to how these principles apply to international sourcing, but if you're doing international, your due diligence needs to be even deeper.

Step 4: Get the Spec in Writing, Down to the Color

This sounds boring, but it's saved me multiple times. For printed packaging—whether it's corrugated boxes with your logo or fiber drums with a special label—spec matters. Industry standard color tolerance is Delta E < 2 for brand-critical colors. Delta E of 2-4 is noticeable to trained observers; above 4 is visible to most people. (Reference: Pantone Color Matching System guidelines.)

I always include in the purchase order:

• Dimensions – exact height, diameter, thickness
• Weight capacity – if it's a drum or IBC
• UN marking if applicable
• Color reference – Pantone number if it's a custom print
• Print location – left side, right side, or all around

Paper weight equivalents: 20 lb bond = 75 gsm (standard copy paper), but for corrugated, you're talking about different flute grades—A, B, C, E, and so on. Don't just say 'heavy duty.' Specify the flute, the board weight, and the bursting strength if it's for shipping heavy components.

One time I ordered 'standard fiber drums' and got something that looked like it was made for confetti. Never again.

Should mention: we'd built in a 3-day buffer for that order, so the wrong drums didn't cause a shutdown. But it was close.

Step 5: Build a Buffer Inventory for the Stuff You Always Need

This is the step that separates smooth operations from fire drills. After 5 years of managing these relationships, I learned that certain items are always going to be needed: standard steel drums, 24" bubble wrap (someone always uses it for shipping fragile prototypes), and 55-gallon plastic drums for waste storage. These aren't the exotic one-offs. They're the staples.

I now maintain a rolling inventory of about 10% above our typical monthly usage for these core items. It doesn't tie up that much capital, and it's saved us from supplier delays more times than I can count. The buffer ensures that if a vendor's production line goes down for a week, we don't have to shut down our line.

This step is not for everyone. If you're dealing with exotic custom drums that cost $200 each, you probably don't want to hold 10% extra. But for the commodity stuff? It's a no-brainer.

Watch Out For

• Standard product vs. custom: Online printers and large packaging suppliers like Greif or PCA can be super efficient for standard drums and containers. But if you need something truly custom—special lining, unique closure, non-standard printing—expect longer lead times and higher minimums. Don't assume their standard catalog covers your need.
• Paperboard quality differences: Not all corrugated is the same. If you're packaging heavy parts, specify the board grade and burst strength. 'Heavy duty' means different things to different suppliers. Reference standard tests like ECT (Edge Crush Test) and Mullen Burst Test, which are industry-recognized standards.
• Audit the approval chain up front: Who needs to sign off on a big drum order? If Finance is going to reject your invoice because the supplier uses handwritten receipts, find out before you order. Not after.

Packaging procurement isn't rocket science, but it's full of small traps. The good news is that once you've fallen into a few of them (like I did), you learn to see them coming. This checklist is what I wish someone had handed me in 2020.
