2936.22.00.00 - Vitamin B1 (Thiamine) and its derivatives

This HTS category, 2936.22.00.00, specifically classifies Vitamin B1, also known as Thiamine, and its derivatives. Thiamine is an essential nutrient crucial for carbohydrate metabolism and nerve function. This includes pure Thiamine hydrochloride, Thiamine mononitrate, and other compounds that are chemically derived from Thiamine and retain its vitamin activity, intended for use as a vitamin supplement or additive.

Unlike sibling categories such as 2936.21.00.00 (Vitamins A) or 2936.23.00.00 (Vitamin B2), this classification is exclusively focused on the B1 vitamin complex. It is distinct from provitamins or general vitamin intermixtures, as it pertains to a specific, unmixed vitamin and its direct derivatives. The key differentiator lies in the chemical identity and primary function as Vitamin B1.

As this is a leaf node within the HTS system, there are no further subcategories. Classification at this level relies on the precise chemical identification of the substance as Thiamine or a direct derivative thereof, and its intended primary use as a vitamin. Exclusions would typically include Thiamine in pharmaceutical preparations for direct medicinal use, which would fall under Chapter 30.
