Tariff-Proofing Your Packaging Sourcing: A 2026 Strategy Guide

Tariff-proofing your packaging means one thing in 2026: knowing exactly how much of your spend sits in materials the government now taxes at 50%, then moving that exposure down on purpose. Section 232 duties on aluminum and steel are no longer a headline you can skim past. They reprice cans, tins, and aerosols at the invoice level, on every order you place. The brands staying flat this year aren't lucky. They mapped it early.

Tariffs don't just raise your costs. They reprice your entire sourcing strategy overnight — and most brands find out one invoice too late.

What exactly changed for packaging in 2026?

The short version: the metal tariffs got broader, and they now bite the full value of what you import. Section 232 duties on aluminum and steel jumped to 50% in June 2025. Then, in April 2026, the rules were restructured to apply against the full customs value of an imported article rather than just its embedded metal content. For a can, a lid, or an aerosol dome, that shift alone raised the duty owed.

A June 2026 modification trimmed rates on some derivative products but kept the full 50% on items made nearly entirely of metal — food and beverage cans included. Trade groups were blunt that this was not a win for packaging. And the raw material underneath it kept climbing: the Midwest Premium for aluminum passed one dollar per pound for the first time in late January. Costs on both ends. No relief in the middle.

It reaches the shelf, too. Carbonated drinks — usually sold in aluminum — rose 3.7% over the year through April, and nonalcoholic beverages climbed 5.1%, per CPI data compiled by FoodNavigator. Some of that is packaging. All of it is your problem if you sell in a can.

How exposed is your packaging spend, really?

Most brands can't answer this. They know their unit prices went up. They can't tell you which line items are tariff-driven versus supplier-driven versus freight. That gap is the whole problem, because you can't hedge a risk you haven't sized.

So size it. We call it the Tariff Exposure Ratio — the share of your total packaging spend sitting in tariff-exposed materials (aluminum, tinplate steel, and their derivatives). Pull your last two quarters of packaging invoices, tag every SKU by primary material, and divide. In the audits I've run at PackageTheWorld, brands with any metal component typically land between 40% and 60% exposed — and more than half had never calculated the number before I asked. That's not a rounding error. That's a strategy sitting unmanaged.

Once you have the ratio, it drives everything downstream: how much redundancy you need, how hard to push on renegotiation, whether substitution is worth the qualification cost. Build it into your risk map. Our guide to packaging supply-chain redundancy walks through where to add slack once you know your exposure. Measure first. Then move.

Should you reshore, substitute, or renegotiate?

There are only three real levers, and most teams reach for the wrong one first. Reshore the supply. Substitute the material. Renegotiate the contract. Each fixes a different problem, and the tariff math decides which.

Reshoring sounds like the obvious answer. Here's the contrarian read: for metal cans, it often isn't. U.S. canmakers still import close to 80% of the tin mill steel they run, and domestic mills don't have the capacity or the technical grade to replace it, according to the Can Manufacturers Institute. "Reshoring" a can supply that depends on imported substrate just moves the tariff one link up the chain. It doesn't erase it.

Substitution is where the real savings hide — swapping a tariff-exposed format for one that isn't. Aluminum aerosol to a PET or coated-paper alternative. A metal tin to a rigid box or a custom-engineered format that hits the same shelf presence without the 50% duty. That said, substitution carries qualification cost and shelf-life risk, so run it on your highest-exposure SKUs only, not the whole catalog.

Renegotiation is the fastest lever and the most overlooked. If you're single-sourced on a tariff-heavy material, you have neither pricing power nor a fallback — a bad place to sit in a 50% world. In my experience it's the first call worth making. Our breakdown of single-source versus multi-source packaging covers when a second qualified supplier pays for itself. Look at the exposure ratio. If it's high and your base is thin, dual-sourcing is not optional.

What number should the final decision hang on?

Not the unit price. The landed, all-in cost — duty, freight, the Midwest Premium, qualification, carrying cost of extra safety stock. A substitution that looks 8% more expensive per unit can win once you fold in the tariff you stop paying and the redundancy you stop needing. This is exactly the trap our total cost of ownership guide was built for — the cheapest quote and the cheapest program are rarely the same line item.

Funny enough, the discipline that gets you through a tariff shock is the same discipline that survives the next one. Map the exposure. Size it honestly. Pick the lever the math points to, not the one that makes a good press release. Then re-run the audit every quarter, because these rules changed twice in six months and they will change again.

Tariffs are a cost you can't vote away. But an exposure ratio you never measured is a cost you chose to ignore. Measure it. Move it. Repeat.
