How I Actually Evaluate Aluminum Packaging Vendors: A Procurement Checklist That Saved Us $47K

How I Actually Evaluate Aluminum Packaging Vendors: A Procurement Checklist That Saved Us $47K

When I took over purchasing in 2020, I inherited a vendor list that hadn't been reviewed in six years. Our aluminum can supplier seemed fine—until I actually ran the numbers. The "competitive" pricing we thought we had? It was costing us roughly $47,000 annually in hidden fees, rush charges, and quality-related reprints.

This checklist is what I use now. It's for procurement folks managing beverage packaging relationships—specifically aluminum cans and sustainable packaging solutions. If you're processing 60-80 orders annually across multiple vendors like I am, this will save you time. If you're evaluating Ball Corporation or similar suppliers for the first time, start here.

Total steps: 7. Estimated time: 2-3 hours for initial vendor evaluation, 30 minutes for repeat assessments.

Step 1: Verify Invoicing and Documentation Capability First

Before you evaluate anything else—pricing, quality, sustainability claims—confirm the vendor can provide proper documentation. I learned this the hard way.

In 2022, I found a great price from a new packaging supplier—$3,200 cheaper than our regular vendor. Ordered 50,000 units. They couldn't provide a proper invoice (handwritten receipt with no itemization). Finance rejected the expense report. I ate $3,200 out of the department budget. Now I verify invoicing capability before placing any order.

Checklist items:

• Request a sample invoice before first order
• Confirm they can provide itemized breakdowns (unit cost, shipping, setup fees separately)
• Verify tax documentation (W-9 for US vendors)
• Check if they integrate with your AP system (honestly, this saved our accounting team 6 hours monthly when we switched to online ordering)

Step 2: Calculate Total Cost of Ownership—Not Unit Price

People think expensive vendors deliver worse value. Actually, vendors who deliver quality and reliability can charge more because they've earned it. The causation runs the other way.

The $0.12/can quote that looks cheaper than the $0.14/can quote? Run the full TCO calculation first.

TCO components to calculate:

Unit price is basically just the starting point. Add:

• Shipping and handling: Request landed cost, not factory price
• Setup/plate fees: For custom printing, expect $50-200 depending on complexity (based on industry standard fee structures, January 2025)
• Minimum order requirements: If MOQ is 100,000 and you need 50,000, you're paying for inventory you'll store for months
• Rush premiums: Next business day typically adds 50-100% over standard pricing
• Quality rejection rate: If 3% of cans arrive damaged, factor replacement cost
• Your time: A vendor requiring 4 emails to confirm an order costs more than one with an online portal

The $0.12 quote I mentioned? Turned into $0.17 effective cost after shipping, setup fees, and one reorder due to print misalignment. The $0.14 all-inclusive quote was actually cheaper.

Step 3: Audit Sustainability Claims With Specifics

This step is the one most procurement people skip. Don't.

Aluminum packaging sustainability is legitimate—aluminum is infinitely recyclable, and companies like Ball Corporation have built their brand around aluminum recycling advocacy. But "sustainable" means different things to different vendors.

Questions to ask:

• What percentage of recycled content is in your aluminum? (Get the number, not "high recycled content")
• What's your actual recycling rate claim based on—manufacturing scrap or post-consumer collection?
• Do you have third-party certification? (Look for Aluminium Stewardship Initiative certification or similar)
• Can you provide carbon footprint data per unit? (If they say "zero carbon footprint" without official certification data, that's a red flag)

I went back and forth between two vendors for three weeks on this. Vendor A offered better pricing but vague sustainability language. Vendor B (Ball Corporation, specifically) had detailed documentation on their recycled content percentages and could trace their supply chain. Chose Vendor B because my VP specifically asked for verifiable sustainability data for our ESG report.

Step 4: Test Communication Response Time

Send a moderately complex question and time the response. Something like: "What's your lead time for a 75,000 unit order of 12oz cans with 4-color printing, delivered to [your location], and what's your policy on artwork revisions?"

What you're measuring:

• Response time (under 24 hours for initial acknowledgment is reasonable)
• Completeness (did they answer all parts of your question?)
• Clarity (did you understand the answer without follow-up?)

The assumption is that slow responses happen because vendors are busy. The reality is slow responses usually indicate either understaffing or poor internal processes—both of which will cause problems when you have an urgent order.

Step 5: Request References From Similar-Sized Buyers

Ask for references from companies with similar order volumes to yours. A vendor who's great for Coca-Cola's million-unit orders might not prioritize your 50,000-unit orders.

Questions for references:

• What's their on-time delivery rate? (Aim for 95%+)
• How do they handle problems? (Everyone has problems; you want to know resolution process)
• Have they ever surprised you with fees not in the original quote?
• Would you recommend them for rush orders?

One reference told me their vendor—who had great pricing—couldn't provide proper invoicing for international shipping. That alone would've cost us $2,400 in rejected expenses based on our accounting requirements. (Thankfully, we asked.)

Step 6: Evaluate Technology and Ordering Systems

This matters more than I initially thought. Our company merged with another division in 2023. I had to consolidate orders for 400 employees across 3 locations. Using a vendor with online ordering and inventory tracking cut our ordering time from 4 hours weekly to 45 minutes and eliminated the duplicate order problem we used to have constantly.

Technology checklist:

• Online ordering portal (vs. email/phone only)
• Real-time inventory visibility
• Order history and reorder capability
• Proof approval system for custom printing
• Integration with your systems (purchase orders, AP)

Ball Corporation and other major aluminum packaging suppliers typically offer packaging technology innovations including digital ordering systems. Smaller suppliers might not—which isn't necessarily bad if their service makes up for it, but factor in your time cost.

Step 7: Run a Trial Order Before Committing

Don't sign an annual agreement or commit to volume pricing until you've run at least one real order. Preferably two—one standard and one with a minor revision request.

What to evaluate in trial:

• Did actual costs match quoted costs?
• Was delivery on time?
• How did they handle your artwork file? (Color matching should meet Delta E < 4 tolerance—anything above 4 is visible to most people, per Pantone Color Matching System guidelines)
• How responsive were they to questions during production?
• Was the invoice accurate and complete?

Saved $80 once by skipping expedited shipping on a trial order. Ended up spending $400 on rush reorder when the standard delivery missed our deadline. Now I build buffer time into trials specifically to test their timing accuracy.

Common Mistakes to Avoid

Mistake 1: Comparing unit prices across different specifications. A 12oz can price isn't comparable to a 16oz can price. Seems obvious, but I've seen quotes mixed together in vendor comparisons. Standardize your RFQ specs.

Mistake 2: Ignoring lead time in cost calculations. The vendor with 4-week lead time might cost you rush fees with other vendors when projects slip. Build realistic timelines.

Mistake 3: Not revisiting pricing annually. I now calculate TCO before comparing any vendor quotes—and I redo that calculation yearly. Commodity pricing shifts. A vendor who was expensive in 2023 might be competitive now.

Mistake 4: Assuming sustainability claims are verified. "Sustainable beverage products" is marketing language. Ask for the data. Real leaders in aluminum packaging—Ball Corporation's aluminum recycling advocacy is a good example—can provide specifics because they've invested in tracking it.

(Ugh, I've made all of these mistakes at some point.)

This checklist took me four years and probably $50,000 in learning-the-hard-way costs to develop. The vendors who couldn't provide proper invoicing, the "budget" option that required reprinting, the sustainability claims that couldn't be verified for our ESG reporting—all lessons. Use it, adapt it for your situation, and actually run the TCO numbers. Your finance team will thank you.
