Last updated: August 2026 dataMethyl isobutyl ketone (MIBK) is a widely used industrial solvent classified under a single 10-digit line, 2914130000, with no further US tariff subdivisions. It serves as a key solvent in coatings, adhesives, and rubber processing, and is also used in solvent extraction of rare earth metals. South Africa and Mexico are the leading US import sources, with Canada also a significant supplier — USMCA origin may affect duty treatment for Canadian and Mexican shipments. Importers should verify whether specific shipments are subject to any applicable trade-remedy orders before entry.

Importers should check for any applicable antidumping or countervailing duty orders on MIBK from specific origins before filing entry. Trade-remedy coverage can change, so consulting CBP's ADCVD portal or a licensed customs broker is advisable.
MIBK is specifically enumerated at the HS6 level (291413) and has its own dedicated 10-digit US tariff line (2914130000), distinguishing it from other acyclic ketones that fall under the residual 291419 basket. The specific enumeration means misclassifying MIBK as a generic acyclic ketone could result in an incorrect duty rate or missed trade-remedy applicability.
