The US taxes tin-plated steel cans at 50% under Section 232 tariffs, but canned food imported already-filled enters duty-free, a gap that contributed to Del Monte closing its Modesto, California cannery in April 2026.
At a glance
- Section 232 tariffs on imported steel, including tinplate (tin-coated steel used for food cans), rose to 50% with all country and product exemptions removed.
- A can filled with food overseas enters the US duty-free as a food product, while the same empty can, or the tinplate to make it domestically, is taxed as a steel derivative, an inversion that taxes American production more than foreign competition.
- Del Monte closed its Modesto, California cannery on April 7, 2026, cutting about 600 full-time and up to 1,200 seasonal jobs, after filing for Chapter 11 bankruptcy in July 2025.
- Nine tinplate production lines in the US have shut since 2018, a 75% decline, leaving the country without the technical capacity to produce enough food-grade tinplate domestically.
What happened
An American food company that cans its own peaches or vegetables domestically now pays a steeper effective tariff than a competitor that fills the same can overseas and ships it to the US already sealed. That's because Section 232 steel tariffs, raised to 50% in mid-2025 with all prior exemptions removed, apply to tinplate, the tin-coated steel sheet used to make food cans, as an imported steel derivative. A can already filled with food, by contrast, is classified as a food product and crosses the border duty-free. Del Monte closed its cannery in Modesto, California on April 7, 2026, cutting roughly 600 full-time and up to 1,200 seasonal jobs, in a shutdown that followed the company's Chapter 11 bankruptcy filing in July 2025.
The details
The mechanics of the problem sit in how US Customs classifies two versions of the same product. Since June 4, 2025, Section 232 tariffs on imported steel have stood at 50%, with every country exemption, company exclusion and product carve-out that used to soften the impact eliminated. Tinplate, thin steel sheet coated with tin, the material food cans are made from, falls under that steel tariff as a derivative product. A can of peaches packed in Greece or tuna packed in Thailand, however, crosses the border classified as food, not steel, and pays no Section 232 duty at all. The result is a system that taxes the American canner's raw material more heavily than it taxes the finished, imported competitor.
Protectionist tariffs are supposed to work by making imports pricier than a domestic alternative, but that logic breaks down when the domestic alternative barely exists. Nine US tinplate production lines have shut down since 2018, a 75% decline, and the country currently lacks the technical capability to produce food-grade tinplate at the volume its canning industry needs. So a tariff meant to protect domestic steelmaking instead raises costs for an industry, canning, that has nowhere domestic left to buy the specific steel product it depends on.
Del Monte Foods filed for Chapter 11 bankruptcy in July 2025 and closed its cannery in Modesto, California on April 7, 2026, eliminating roughly 600 full-time positions and up to 1,200 seasonal jobs. The plant had processed close to a third of California's cling peach crop, and its closure left more than 200 family growers in Sutter County holding unsold fruit, with losses estimated above $550 million. None of that traces to tinplate tariffs alone, Del Monte's bankruptcy involved more than $1 billion in liabilities, but the tariff-inversion cost structure sits squarely inside the industry conditions that made a domestic cannery harder to keep running profitably.
The trade data shows where that gap is pushing volume. Total US canned food imports climbed from $1.6 billion in 2018 to $3.2 billion in 2026. Shipments from Thailand are up 118% over that period, Italy up 396%, Greece up 301% and Egypt roughly twentyfold. Canned peaches specifically now arrive from overseas for about half of everything sold in the US, up from 16% in 2012. Domestic canners have pressed for a fix since 2018, either excluding tinplate sourced from allied countries from Section 232 tariffs until US capacity can be rebuilt, or applying the same duty to filled cans that already applies to the empty ones, but neither change has been made.
Why it matters
This isn't really a story about the price of tin. It's a story about what happens when a tariff is built around a product category that no longer maps cleanly onto how the product actually gets made and sold, and the same tinplate math could apply to any packaged good that crosses the US border partly assembled versus fully finished. For a reader tracking metals markets, it's a reminder that tariff policy can move demand for a specific metal application, tin-coated steel cans in this case, without moving the underlying global metal price at all, since the effect here is about where cans get filled, not how much tin the world consumes.
Our read
Outlook: neutral. This is a US trade-classification story about where canned food gets packed, not a driver of global tin supply or demand. It redirects canning activity toward countries with duty-free access rather than changing how much tin-coated steel the world uses overall.
What to watch
- Whether Section 232 grants an exclusion for tinplate sourced from allied suppliers
- Any move to apply Section 232-equivalent duties to filled canned-food imports
- US tinplate production-line closures or reopenings
- Canned food import volumes from Thailand, Italy, Greece and Egypt in coming trade data

- 2026-09-08: The Washington Times reports on the tariff gap between tinplate and filled canned-food imports.
Supply Drivers
Nine US tinplate production lines have shut since 2018, a 75% decline, and the country currently lacks the technical capacity to produce food-grade tinplate at the volume its canning industry needs, meaning tariff protection on tinplate imports has no domestic supply base to redirect demand toward.
Government Policies
Section 232 steel tariffs, raised to 50% on June 4, 2025 with all country, company and product exemptions eliminated, classify tinplate as a steel derivative subject to the full duty, while filled food cans are classified separately as food products and enter duty-free.
Trade Tariffs
The resulting tariff inversion, a 50% duty on empty tin-coated steel cans and tinplate versus zero duty on the same can already filled with food, has coincided with canned food imports rising from $1.6 billion in 2018 to $3.2 billion in 2026, with import growth concentrated in Thailand, Italy, Greece and Egypt.
What could lift prices
- Rising import volumes for filled canned food, up from $1.6 billion in 2018 to $3.2 billion in 2026, could support tinplate demand in the countries doing that overseas canning, such as Thailand, Italy, Greece and Egypt.
What could weigh on prices
- US tinplate production capacity has fallen 75% since 2018, and a 50% Section 232 tariff on the material isn't rebuilding that capacity, it's raising costs for the canners still trying to use it domestically.
- The tariff inversion gives foreign canners a structural cost advantage over US canneries for as long as filled cans keep entering duty-free while tinplate doesn't.
Country impact
| Country | Impact | Reason |
|---|---|---|
| United States | High | Domestic canners pay the full Section 232 tariff on tinplate while competing against duty-free filled-can imports, a cost structure that contributed to Del Monte's Modesto, California cannery closure. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Food Processing | Negative | Domestic canners face a 50% tariff on the tinplate they need while competing against duty-free imports of the same product already filled and sealed. |
| Metal Packaging | Negative | US tinplate production capacity has fallen 75% since 2018, leaving the domestic can-making supply chain unable to meet demand even before tariffs are factored in. |
Who gains, who loses
- Overseas canners in Thailand, Italy, Greece and Egypt: Their filled cans enter the US duty-free, a structural cost advantage over US canneries that must pay the 50% tinplate tariff.
- US canned-food producers and domestic fruit and vegetable growers: Canners pay a 50% tariff on tinplate with no adequate domestic supply to switch to, and grower losses follow when a cannery like Del Monte's Modesto plant closes, more than $550 million in estimated losses for Sutter County growers alone.
Other ways this could play out
- Excluding tinplate from allied suppliers from Section 232 tariffs until US capacity is rebuilt, an approach domestic canners have requested since 2018, would remove the cost disadvantage without requiring new US tinplate capacity to appear immediately.
- Applying the same tariff rate to filled food cans that already applies to empty tinplate would close the inversion from the other direction, though it would raise prices on imported canned food for US consumers.
Price risks
- A tinplate exclusion for allied suppliers could ease costs for remaining US canners but wouldn't reverse plant closures that have already happened.
- Continued growth in duty-free filled-can imports could keep pressuring the domestic canning industry regardless of any change to the tinplate tariff itself.
