Last updated: August 2026 dataParts classified here support the same diverse equipment universe as the parent heading 8479, covering components for industrial robots (8479909530/8479909640), public-works machinery (8479909550/8479909650), metal-treatment machinery (8479909565/8479909665), wood and cork presses (8479909560/8479909660), and trash compactors across several dedicated lines. Germany is the leading supplier, with China and Mexico also prominent — a mix that means Section 301 exposure is a live concern for Chinese-origin parts, while Mexican-origin components may benefit from USMCA treatment when origin criteria are satisfied. The principal classification challenge is establishing that a part is "solely or principally" used with a machine classifiable in heading 8479 rather than with equipment in another heading, which determines whether this provision or a more specific parts heading applies.

The key test is the principal-use rule: if the part is solely or principally used with a machine classifiable in heading 8479, it belongs here. If the parent machine has its own dedicated parts heading (e.g., parts of pumps under 8413.91), that specific provision takes precedence. Detailed bills of materials and OEM documentation linking the part to its parent machine are essential for defending the classification.
Parts of industrial robots classified under 8479909530 or 8479909640 that originate in China are generally subject to Section 301 tariffs. Importers should verify the applicable list and any product-specific exclusions, as the scope and exclusion status of Section 301 measures can change. Consulting a licensed customs broker before entry is recommended.
