Mexico HS Code

HS Code 381590: Reaction initiators, reaction accelerators and catalytic preparations n.e.s. (excl. rubber accelerators and supported catalysts) in Mexico

Q: Is HS code 381590 the same across all countries?

Yes — up to the 6-digit level, HS code 381590 is the same in every WCO member country. Beyond 6 digits, each country extends the code for national tariff and statistical use. Mexico extends it under TIGIE.

Q: What system does Mexico use to classify HS code 381590?

Mexico classifies products under the Tarifa de la Ley de los Impuestos Generales de Importación y Exportación + NICO (TIGIE; locally TIGIE + NICO), which extends HS codes to 10 digits. The first 6 digits align with the WCO Harmonized System, and the rest cover national tariff and statistical needs.
