New Tariffs Hit Tin Mill Products From China, Taiwan & Turkey

The U.S. International Trade Commission (USITC) has issued affirmative final injury determinations on tin mill products from China, Taiwan, and Turkey, paving the way for antidumping (AD) and/or countervailing duties (CVD) to be imposed on these imports — a major cost shift for manufacturers and distributors who rely on these materials.

Published in the Federal Register on May 29, 2026, this ruling marks the conclusion of a significant trade remedy investigation and will have real consequences for small and medium businesses that use tin mill products in food packaging, industrial components, and consumer goods manufacturing.

⚠️ Disclaimer: Tariff rates and trade remedy determinations change frequently. This post reflects information available as of the publication date. Always verify current rates with U.S. Customs and Border Protection (CBP) or a licensed customs broker before making business decisions.


What Are Tin Mill Products, Exactly?

Tin mill products (flat-rolled steel products that have been coated with tin, chromium, or chromium oxides, typically used in food and beverage cans, aerosol containers, and industrial packaging) are a foundational input for industries ranging from food processing to paint manufacturing.

Common tin mill product types include:

  • Electrolytic tinplate (ETP): The familiar shiny steel used in soup cans and pet food containers
  • Tin-free steel (TFS) / Electrolytic chromium-coated steel (ECCS): Used in bottle caps, aerosol ends, and general packaging
  • Blackplate: Uncoated cold-rolled steel used as a substrate

These products are classified under HS codes (Harmonized System codes — the international numerical system used to classify traded goods) primarily in the 7209, 7210, and 7212 series. Importers should work with a licensed customs broker to confirm the exact HS codes applicable to their specific goods.


What Did the USITC Actually Decide?

The USITC (U.S. International Trade Commission — the independent federal agency that conducts trade remedy investigations) issued affirmative final injury determinations, meaning the Commission concluded that U.S. domestic tin mill product producers are materially injured, or threatened with material injury, by reason of imports from China, Taiwan, and Turkey.

This is the critical final step that authorizes the U.S. Department of Commerce (DOC) to issue antidumping duty (AD) orders (duties imposed when foreign goods are sold in the U.S. at less than fair value) and potentially countervailing duty (CVD) orders (duties that offset foreign government subsidies) against these countries.

What's the Difference Between an AD and CVD Order?

Order TypeWhat It AddressesWho Investigates
Antidumping (AD)Goods sold below fair market valueCommerce + USITC
Countervailing (CVD)Foreign government subsidiesCommerce + USITC

Both types of orders result in additional duties assessed at the border, layered on top of any existing Section 301 tariffs (in China's case) or general Most Favored Nation (MFN) rates already in effect.


Why Does This Matter to Small Business Importers?

For small and medium businesses, the impact of AD/CVD orders is often underestimated until the first customs bill arrives. Here's why this ruling deserves your immediate attention:

1. Duties Can Be Retroactive

Under U.S. trade remedy law, once a preliminary determination is made, CBP (U.S. Customs and Border Protection — the agency that enforces trade laws at the border) can require importers to post cash deposits or bonds covering estimated duty rates — and final assessed rates can be adjusted retroactively through an administrative review process. This means an importer could face a higher bill months after goods have already landed and sold.

2. Rates Can Be Substantial

Antidumping margins in steel-related cases have historically been significant. While the exact AD/CVD rates for this specific determination will be published by the Department of Commerce separately, past steel tin mill cases have seen margins ranging from the low single digits to well over 100% for certain producers. Importers should not assume the rates will be modest. (Note: Exact rates for this specific determination should be confirmed via the official Federal Register notice and CBP's ACE system.*)

3. China Faces Compounding Duties

Chinese tin mill products already face Section 301 tariffs (additional tariffs imposed under Section 301 of the Trade Act of 1974, targeting unfair trade practices) of up to 25% or more, depending on the product. New AD/CVD duties would stack on top of those existing tariffs, making Chinese-origin tin mill products significantly more expensive to import compared to just a year ago.

4. Taiwan and Turkey Are Now in Scope

Importantly, this ruling doesn't just target China. Taiwan and Turkey are both covered, meaning importers who may have already shifted sourcing away from China to avoid Section 301 tariffs could now face new duty exposure from these alternative suppliers as well.


Which Products and Countries Are Affected?

Countries Covered:

  • 🇨🇳 China (People's Republic of China)
  • 🇹🇼 Taiwan
  • 🇹🇷 Turkey

Products in Scope:

The investigation covers tin mill products, broadly defined as flat-rolled steel coated with tin, chromium, or chromium oxides. This generally includes:

  • Electrolytic tinplate in coils or cut lengths
  • Tin-free steel / ECCS
  • Blackplate intended for further tin coating

Products NOT typically in scope include tin mill products that have been further manufactured into finished goods (e.g., completed cans or containers), though importers should confirm scope applicability with a customs broker, as scope rulings can be complex.


What Should Importers Do Right Now?

If your business imports tin mill products — or manufactures goods that contain them — here is a concrete action plan:

✅ Step 1: Audit Your Supply Chain

Identify whether any of your current or pending purchase orders involve tin mill products sourced from China, Taiwan, or Turkey. Check shipping documents, invoices, and your supplier's country of origin certifications.

✅ Step 2: Confirm Your HS Codes

Work with a licensed customs broker (a professional licensed by CBP to facilitate the import process and ensure regulatory compliance) to confirm the correct HS classification for your goods. The scope of AD/CVD orders is classification-specific, and an incorrect HS code can lead to missed duty liability — or unnecessary duty payments.

✅ Step 3: Check for Cash Deposit Requirements

Contact your customs broker or check CBP's ACE portal to determine whether cash deposit requirements are currently in effect for your suppliers. If you have shipments in transit, this is urgent.

✅ Step 4: Review Supplier Contracts

If your contracts include a "duty escalation" or "change in law" clause, now is the time to invoke it or review renegotiation options with your suppliers. If no such clause exists, consider adding one to future contracts.

✅ Step 5: Explore Alternative Sourcing

Countries not currently subject to AD/CVD orders on tin mill products — such as South Korea, Germany, or Japan — may represent viable alternative sources. Any sourcing shift, however, should be evaluated against existing trade agreements, lead times, and quality standards.

✅ Step 6: Consider a Scope Exclusion Request

If you believe your specific product may not fall within the defined scope of the order, the Department of Commerce accepts scope ruling requests. This is a formal process and typically requires legal assistance.


Timeline: What Happens Next?

MilestoneWhat It Means
USITC Final Determination (May 29, 2026)Injury confirmed — AD/CVD orders authorized
Commerce Department AD/CVD OrdersFormal duty orders published in Federal Register (typically within days to weeks of USITC determination)
Cash Deposit Rate Effective DateImporters must deposit estimated duties at CBP on all covered entries
First Administrative Review (approx. 1 year post-order)Duty rates may be adjusted up or down based on actual pricing data

Importers with shipments already in transit should treat this as time-sensitive. Consult your customs broker immediately.

---FAQ--- Q: Which countries are covered by the tin mill products tariff determination? A: The USITC's May 2026 determination covers tin mill products imported from China (People's Republic of China), Taiwan, and Turkey. Each country may face different duty rates depending on the Commerce Department's individual margin calculations. ---END FAQ---

---FAQ--- Q: How do antidumping duties stack with existing Section 301 tariffs on Chinese goods? A: They are additive. If Chinese tin mill products face a 25% Section 301 tariff and a new antidumping duty rate, both are assessed on the customs value of the goods. This can make total duty liability substantial and significantly impact landed costs for importers sourcing from China. ---END FAQ---

---FAQ--- Q: Can I request an exclusion from antidumping and countervailing duty orders? A: You can request a formal scope ruling from the Department of Commerce if you believe your specific product falls outside the defined scope of the order. This is a legal process; consulting a licensed customs broker or trade attorney is strongly recommended. ---END FAQ---

---FAQ--- Q: Where can I find the official antidumping and countervailing duty rates for tin mill products? A: Official rates are published in the Federal Register by the U.S. Department of Commerce. You can also check CBP's ACE (Automated Commercial Environment) system or consult a licensed customs broker for the most current cash deposit rates applicable to your specific supplier. ---END FAQ---
