How to Choose an Industrial Packaging Partner: A 7-Step Quality Checklist (From Someone Who Rejects Bad Specs)

If you’re in charge of sourcing for a manufacturer, a chemical company, or a food processor, you already know that buying industrial packaging isn’t like buying office supplies. The difference between a good batch of drums and a bad one can mean the difference between a smooth production run and a $22,000 redo (yes, I’ve seen that).

Choosing a partner like Greif, or any other industrial packaging supplier, comes down to a checklist. Not a "go with your gut" feeling. I’ve been on the receiving end of substandard containerboard and drums for years, and I’ve developed a process to vet suppliers before they cost you money.

Here’s the 7-step checklist I use, specifically for B2B industrial packaging procurement. If you follow this, you’ll avoid about 80% of the common pitfalls I see in this industry.

1. Define Your “Specification Non-Negotiables” First

Before you even talk to a supplier, get your specs in order. This sounds basic, but I can’t tell you how many times I’ve seen a purchase order go out with a “standard drum” description. What’s standard to you might not be standard to someone else.

In Q1 2024, we received a batch of 500 reconditioned drums where the wall thickness was visibly off—0.8mm against our 1.2mm spec. Normal tolerance is ±0.1mm. The vendor claimed it was “within industry standard.” We rejected the batch, and they redid it at their cost. Now, every contract I write includes clear wall thickness requirements.

Your list should include:

• Material grade and thickness
• UN certification (if relevant)
• Cleanliness level for food-grade
• Printing or labeling specs
• Packaging and palletization

2. Audit Their “Quality Hold” Process

Every large packaging supplier—whether it’s Greif, Mauser, or someone else—has a quality team. But how do they handle a batch that’s borderline? Ask to see their non-conformance report workflow.

It’s tempting to think that all vendors just sort out bad product automatically. The reality is that if you don’t have a clear process to catch outliers, they slip through.

I ran a blind test with our warehouse staff: same drum from two different suppliers. 70% identified one supplier’s drums as “more uniform” without knowing which was which. The cost difference was about $1.50 per drum. On a 10,000-unit annual order, that’s $15,000 for measurably better consistency.

3. Check Their Global Consistency

If your company operates across multiple plants or regions, this is a big one. A global supplier like Greif has the advantage of a diverse portfolio and a large footprint, but that doesn’t automatically mean every plant runs the same specs.

Ask for a “global spec comparison.” Request approval drawings from three different manufacturing sites (if applicable) and put them side-by-side. I’ve seen “the same” containerboard vary in burst strength by 15% between two plants because of minor differences in the raw material sourcing.

4. The “Rush Order” Test

From the outside, it looks like vendors just need to work faster for rush orders. The reality is rush orders often require completely different workflows and dedicated resources.

I always ask a potential supplier: “What’s your process for a 10-day rush on a standard drum order?” If the answer is “We just bump it up in line,” that’s a red flag. A good answer includes:

• A dedicated rush queue
• Separate raw material allocation
• An expedited QA check

If they don’t have a formal process, the quality is almost always at risk during a rush.

5. Evaluate Their Sustainability Reporting (Not Just Claims)

Most industrial packaging companies claim to be sustainable now. But I want to see data. For a company like Greif, which operates in the paper-based packaging space, I’d want to know the percentage of recycled content in their containerboard, and whether that percentage is verified by an independent body.

Ask for their “environmental product declaration.” If they can’t provide one, their sustainability claims are likely just marketing. It’s a straightforward ask in B2B procurement.

So glad I started asking for this a few years ago. Almost took a supplier’s marketing material at face value, which would have set us up for a compliance headache. The declaration showed their recycled content was 20% lower than what their brochures implied.

6. The Hidden Cost of “Cheap”

My view on this is simple: the lowest quote is rarely the cheapest option. When we switched to a lower-cost containerboard supplier, we saved about $0.10 per unit on the quote. But we had to reject 8% of the first delivery due to moisture damage during storage, which cost us overtime to sort and restock.

That $0.10 per unit saving turned into a $0.35 per unit problem.

In my experience managing procurement for a mid-sized chemical company, the lowest quote has cost us more in 60% of cases when you factor in inspection time, rework, and delays.

Look at the total cost: freight, customs (if international), warehousing risk, and rejection rate.

7. Test Their Customer Service Boundaries

Finally, call their customer service line with a problem. Ask something slightly difficult, like “Can I get a batch of IBCs with a different valve fitting?”

See how they handle it. A good supplier won’t say “no” immediately. They’ll say “l let me check with our technical team.” A bad supplier will say “that’s a special order, costs more.”

The value of a good supplier isn’t just the product on the truck. It’s how they handle your question when you need to solve a problem next Tuesday at 4pm.

Final Note: Common Mistakes

Don’t fall into the trap of “we’ve always used them” without reviewing the contract annually. I knew I should review the whole agreement more rigorously last year, but thought “we’ve worked together for 5 years.” That was the one time a small price increase went unnoticed for two quarters.

Review your packaging vendor like you review any other critical supplier. It’s not personal. It’s quality control.
