HTS Chapter 31
41 HTS codes in this chapter
Chapters 28 through 38 cover inorganic and organic chemicals, pharmaceutical products, fertilizers, tanning agents, essential oils, soaps, explosives, photographic products, and miscellaneous chemical products. This sector is highly regulated due to potential impact on public health and environment. In Mexico, COFEPRIS controls the import of pharmaceutical products and regulated chemical substances, while SEMARNAT oversees products with potential environmental impact. Correct tariff classification determines not only the duty rate but also applicable permits and non-tariff regulations.
