Harmonized System Update (HSU) 2524: What You Need to Know

For importers, customs brokers, and anyone involved in international trade, staying on top of the Harmonized Tariff Schedule (HTS) is crucial. These codes dictate tariffs, duties, and import requirements, making accurate classification essential for smooth and compliant operations. That's why every Harmonized System Update (HSU) released by Customs and Border Protection (CBP) is an important event.

Today, we're diving into the details of CSMS # 65475028 - Harmonized System Update (HSU) 2524, which was created on June 27, 2025.

Key Highlights of HSU 2524:

  • Comprehensive Update: HSU 2524 is a substantial update, containing 114 Harmonized Tariff Records and 484 ABI records. This indicates a wide range of adjustments and new classifications that may impact various goods.
