The NMMA continues to monitor and analyse developments

Earlier this week President Donald Trump made changes to his tariff policy to prevent specific products from being taxed with multiple tariffs – known as ‘stacking’ – and the affected auto part codes could spillover into the marine trade.

The National Marine Manufacturers Association (NMMA) is out with a first look at the new order, while awaiting the detailed guidance contained in the Federal Register Notice, and the changes seem equally convoluted.

If your product – or Harmonized Tariff Schedule (HTS) code – is included in the March 26 auto parts notice, it is still subject to the 25% auto part tariff but exempt from the 25% tariff for non-compliant USMCA (US, Mexico, Canada Agreement) products or the 25% tariffs on aluminium and steel imports. Several auto parts codes overlap with imported marine hardware.

However, five tariffs will continue to ‘stack’ including the 10% universal tariff on imports into the US; 0.5% to 25% Section 301 tariffs on imports from China; 125% reciprocal tariffs on imports from China; 20% IEPPA tariffs on imports from China, and antidumping and countervailing duties.

The order gives the Department of Homeland Security until mid-May to implement the necessary customs changes, which will be applied retroactively to all entries of merchandise subject to any applicable tariffs outlined in the order and made on or after March 4, 2025.

Any refunds will be processed pursuant to applicable laws and US Customs and Border Protection’s standard procedures for such refunds.

NMMA continues to monitor and analyse developments as well as lobbying the government for a “nuanced approach to tariffs that keep the uniquely American recreational boating industry competitive at home and abroad.”
