Special Dies, Tools, Die Sets, Jigs & Fixtures

When a US importer purchases special tooling from a related party (e.g., a foreign affiliate), CBP scrutinizes whether the transaction value reflects an arm's-length price. If the relationship influenced the price, importers may need to use alternative valuation methods — such as deductive value or computed value — or demonstrate that the price is consistent with test values. Detailed cost documentation from the foreign manufacturer is essential.

Yes. Special dies, jigs, and fixtures are generally classified under HTS heading 8466 (parts and accessories for machine tools) or heading 8207 (interchangeable tools), depending on their design and function. The classification turns on whether the item is a self-contained tool or a machine-mounted accessory, and errors between these headings are a common audit finding. A binding ruling from CBP is advisable for high-value or recurring shipments.
