2931.49.00.20 - N-(Phosphonomethyl) glycine (glyphosate) and its salts and esters

This HTS category, 2931.49.00.20, specifically covers N-(Phosphonomethyl) glycine, commonly known as glyphosate, along with its various salts and esters. Glyphosate is a widely used organophosphorus herbicide, and its classification here is based on its chemical structure as an organo-inorganic compound containing both phosphorus and nitrogen, without halogenation.

Within the broader group of "Other organo-phosphorous derivatives" (2931.49), this specific code is distinguished from its siblings by its unique chemical identity and primary application. For instance, while other entries might cover phosphoramidocyanidates or phosphonites, this subcategory is exclusively for glyphosate and its derivatives. It is also distinct from 2931.49.00.10, which covers glufosinate, another herbicide but with a different chemical structure. The focus here is solely on the phosphonomethyl glycine molecule and its salts or esters.

As a leaf node, this HTS classification does not have further subcategories. Therefore, the classification relies entirely on the precise identification of the substance as glyphosate or one of its direct salts or esters. Importers and exporters should ensure their documentation accurately reflects the presence and form of glyphosate to ensure correct classification under this specific code.
