Changes in U.S. customs policy

The United States has recently been making dynamic changes to its customs policy. How does this affect EU importers operating in the US market? 

The following are key aspects that may affect the cost and conduct of transatlantic trade.

New tariffs on steel and aluminum – expanded scope 

• As of March 12, 2025, import duties on steel and aluminum have increased to 25% and are now standardized across all countries.
• The previously applicable exemptions introduced in 2018 for certain trade partners — including Canada, Mexico, the European Union, Japan, and the United Kingdom — have now been removed.
• The new regulations also cover products containing steel or aluminum, which may impact a wide range of industrial and consumer goods. 

Importer’s responsibility for correct tariff classification 

Under U.S. regulations, full responsibility for accurate tariff declarations and HS code classification lies with the importer, not the customs broker. Accordingly:

• The importer must ensure that the HS code submitted during customs clearance accurately reflects the composition and nature of the product.
• Incorrect classification may result in financial penalties, clearance delays, and audits by U.S. Customs and Border Protection (CBP). 

To minimize the risk of incorrect classification, we recommend: 

• Consulting a customs auditor for additional verification of product classifications and HS codes.
• Requesting a Binding Ruling – an official CBP decision that provides legal certainty and helps avoid disputes during customs clearance.
