Last updated: July 2026 dataClassified as not elsewhere specified (N.E.S.), these replacement and component parts serve industrial and laboratory equipment designed to change or maintain temperature — including heat exchangers, industrial furnaces, ovens, and cooling apparatus. The N.E.S. designation means classification here is residual: importers must confirm that no more specific SITC heading captures the part before using this code. Correct classification often hinges on whether the part is identifiable as belonging to a specific machine type, which can affect applicable duty rates and trade-remedy exposure.

A part is classified as N.E.S. only when no other SITC heading more precisely describes it. If the part is identifiable as belonging to a specific type of temperature-changing machine — such as a refrigeration compressor or a specific heat exchanger — it should be classified under that machine's dedicated heading. Consult a licensed customs broker to confirm the correct classification.
Depending on the country of origin and the specific HTS subheading, parts for industrial machinery can be subject to Section 301 tariffs or antidumping/countervailing duty orders. Importers should verify the applicable 10-digit HTS code and check current trade-remedy orders with CBP before entry.
