ITC Section 337 Case: Nanolaminate Alloy Coated Metal Parts
On 30 April 2026, the ITC's presiding administrative law judge issued a Final Initial Determination finding a violation of Section 337 in an investigation into certain nanolaminate alloy coated metal parts and products containing them. The Commission is now soliciting public comments on the recommended relief and bonding provisions before deciding whether to uphold the violation finding.

The U.S. International Trade Commission announced on 6 May 2026 that an administrative law judge has issued a Final Initial Determination (FID) on a Section 337 violation involving certain nanolaminate alloy coated metal parts and products containing the same. Section 337 of the Tariff Act prohibits unfair methods of competition and unfair acts in the importation of articles into the United States.
Violation Finding and Remedy Phase
According to the notice, the FID includes not only a finding of violation but also a Recommended Determination on remedy and bonding. Remedies in Section 337 cases typically include exclusion orders (barring entry of infringing goods) and/or cease-and-desist orders against U.S. importers and sellers. Bonding provisions determine what security, if any, importers must post pending the Commission's final decision.
Public Interest Comment Period
"The Commission is soliciting submissions on public interest issues raised by the recommended relief should the Commission find a violation. This notice is soliciting comments from the public and interested government agencies only."
The public interest phase is a critical juncture in Section 337 investigations. Before the Commission can impose remedies, it must weigh whether doing so would harm the public interest—including effects on consumers, competing U.S. industries, and the general economy. Interested parties, including competitors, customers, trade associations, and government agencies, are invited to file comments on whether the recommended relief serves or harms the public interest.
What this means for shippers
If the Commission upholds the violation and imposes an exclusion order on nanolaminate alloy coated metal parts, importers of these goods will face immediate entry denials at U.S. Customs unless they obtain a specific exclusion or settlement. Monitor the final Commission determination—expected within months—and identify whether your sourced parts fall within the scope of the investigation. Consult product classifications and supplier certifications now; delays in re-engineering or sourcing alternatives after a final order are costly. File a public interest comment if your supply chain is affected.
