Sintered neodymium-iron-boron (NdFeB) permanent magnets from China have been subject to antidumping and countervailing duty orders, in addition to Section 301 tariffs. Importers should check the current scope of any active AD/CVD orders with CBP and the International Trade Administration before entry, as scope rulings can determine whether a specific magnet grade or form is covered.

Unmagnetized blanks or preforms made from permanent-magnet alloy (e.g., NdFeB or SmCo) that will be magnetized after import are explicitly included in this heading alongside finished magnets. The key classification criterion is the alloy composition and intended use, not the magnetization state at time of import. Importers should declare the material composition and end use to support correct classification.
