US opens anti-dumping probe on tin mill products from China, Taiwan, Türkiye
The US Department of Commerce initiated less-than-fair-value (LTFV) investigations on tin mill products from China, Taiwan, and Türkiye on May 5, 2026. These investigations will determine whether exporters in these countries are selling tin mill products in the US at prices below fair value, which could result in anti-dumping duties. Shippers importing tin mill products from these three countries should monitor the investigation timeline and prepare for potential tariff implications.

The US Department of Commerce initiated less-than-fair-value (LTFV) investigations on tin mill products imported from the People's Republic of China, Taiwan, and the Republic of Türkiye, effective May 5, 2026. These investigations will examine whether producers and exporters in these countries are selling tin mill products to the United States at prices below fair value, potentially triggering anti-dumping duties.
Who is affected
Shippers and importers sourcing tin mill products from China, Taiwan, or Türkiye face potential anti-dumping tariffs. Tin mill products typically fall under HS Chapter 72 (Iron and Steel) classifications. Exporters in all three countries are subject to investigation simultaneously.
Investigation process and timeline
Less-than-fair-value investigations by the Department of Commerce typically follow a standard timeline:
- Preliminary determinations occur around 140 days after initiation
- Final determinations follow approximately 75 days later
- If dumping is found, the International Trade Commission (ITC) conducts a separate injury investigation
- Preliminary and final duties may be imposed pending investigation outcomes
During the investigation period, merchandise may be subject to provisional duties, and importers should expect increased compliance requirements and potential retroactive duty exposure.
What this means for shippers
Importers of tin mill products from China, Taiwan, and Türkiye must immediately review their supply chains and understand HS classification for their specific products. File comments with Commerce during the investigation if you are a US importer or producer. Expect provisional anti-dumping duties within months and prepare pricing models that account for potential tariff escalation. Monitor Federal Register for preliminary determination notices. Use our HS code lookup to confirm classification and verify country-of-origin for any tin mill imports now.
