Mexico HS Code

HS Code 391390: Natural polymers and modified natural polymers, e.g. hardened proteins, chemical derivatives of natural rubber, n.e.s., in primary forms (excl. alginic acid and its salts and esters) in Mexico

Q: Is HS code 391390 the same across all countries?

Yes — up to the 6-digit level, HS code 391390 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 391390?

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.
