2939.69.00.00 - Other 🖩

This HTS category, 2939.69.00.00, encompasses "Other" alkaloids derived from rye ergot and their salts, ethers, esters, and other derivatives, which are not specifically enumerated under the preceding subheadings. Essentially, it serves as a residual category for any ergot-alkaloid related compounds that do not fall into the more defined classifications. This includes complex synthetic or naturally occurring ergot alkaloids and their immediate chemical modifications that do not precisely match the structures of ergometrine, ergotamine, or lysergic acid, or their direct salts.

The primary distinction of this category lies in its inclusiveness of ergot-alkaloid derivatives beyond the specifically listed compounds. While 2939.61.00.00 covers ergometrine and its salts, and 2939.62.00.00 covers ergotamine and its salts, and 2939.63.00.00 covers lysergic acid and its salts, this "Other" category is for any remaining substances within the broader family of alkaloids of rye ergot that do not fit those precise definitions. The classification hinges on whether a substance is demonstrably an alkaloid derived from rye ergot, and if it's a salt, ether, ester, or other derivative, but does not correspond structurally or chemically to the more specific sibling categories.

As this is a leaf node, there are no further subcategories to introduce. Therefore, classification into 2939.69.00.00 relies on a thorough chemical analysis to confirm the substance's origin and derivative status, coupled with a detailed comparison against the defining characteristics of the specifically listed ergot alkaloids and their salts. When a product is identified as an ergot alkaloid derivative but does not meet the precise criteria for ergometrine, ergotamine, or lysergic acid and their salts, this residual classification becomes applicable.
