Mexico HS Code

HS Code 730451: "Tubes, pipes and hollow profiles, seamless, of circular cross-section, of alloy steel other than stainless, cold-drawn or cold-rolled ""cold-reduced"" (excl. line pipe of a kind used for oil or gas pipelines, casing and tubing of a kind used for drilling for oil)" in Mexico

Q: Is HS code 730451 the same across all countries?

Yes — up to the 6-digit level, HS code 730451 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 730451?

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.
