Trump administration posts proposed automotive parts Section 232 tariff expansion for public input

On January 15, 2026, the US Department of Commerce International Trade Administration (ITA) posted the applications it received during the second round of the Section 232 automotive parts tariff inclusions process for public input.¹ The inclusions process allows domestic manufacturers to submit requests for new products to be added to the 25% Section 232 tariff on automotive parts during a two-week application window, which occurs four times per year (in this case, January 1, 2026 to January 14, 2026).²

Now that the applications are posted for public review, stakeholders have two weeks to respond to the proposed inclusions before ITA proceeds with its decisions.
 

Inclusion applications received

ITA received 11 applications from 3 companies, which include 10 unique HTSUS codes at the 10-digit level (several applications include the same tariff codes and one code is incorrect). In 2024, the United States imported goods valued at US$14 billion under these classifications.

• HTSUS 3917.40.0095: Other Fittings for Tubes, Pipes & Hoses, of Plastic, not elsewhere specified or included (NESOI).
• HTSUS 8412.21.0075: Linear Acting Hydraulic Motors (Cylinders), NESOI.

Next steps

Interested parties have until January 29, 2026 at 11:59 pm EST to submit comments responding to the inclusion applications. According to the ITA, collecting public comments on the inclusions applications “will ensure a transparent, complete, and legally robust process for conducting analysis and making final determinations of [automobile parts] inclusion requests.”
Posting the applications for public comment also starts the 60-day period for ITA to complete its internal review and decisions, with a deadline of March 16, 2026. Any tariff increases would be implemented shortly thereafter through a Federal Register Notice.

Status of the October 2025 inclusions round

Despite proceeding with the January inclusions round, ITA is still finalizing the decisions on applications submitted in the October 2025 round.³  According to the interim regulations for the inclusions processes, ITA should have finalized its decisions by around December 15, 2025. ITA has not announced a new target date for completion of the decisions.
