Updated Tariff Guidance for Japanese Imports: On September 9, 2025, US Customs and Border Protection announced new tariff structures for Japanese-origin imports, setting a 0% reciprocal tariff for goods with a Column 1 duty rate of 15% or higher and a combined rate of 15% for those below 15%, effective for imports entered on or after August 7, 2025.
Public Comment Opportunity on Section 301 Exclusions: The US Trade Representative is seeking public input on whether to extend tariff exclusions for certain Chinese-origin imports beyond November 2025, focusing on technology transfer and intellectual property issues, with comments due by October 16, 2025.
Actions for Affected Businesses: Companies importing goods into the US should analyze the impact of the updated tariffs, engage with legal and trade advisors for compliance, evaluate existing contracts for tariff implications, and consider the complexities of transfer pricing adjustments related to the new duty structures.
