2939.19.20.00 - Synthetic

This classification, HTS Code 2939.19.20.00, encompasses synthetic alkaloids of opium and their derivatives, specifically those that are not explicitly enumerated in more specific subheadings. It is crucial to understand that this category is dedicated to compounds that are structurally related to opium alkaloids but are manufactured through chemical synthesis rather than extracted from natural sources. The key distinguishing factor is their synthetic origin, which places them apart from naturally occurring or synthesized but differently categorized alkaloids.

Within the "Other" subcategory at this level, HTS Code 2939.19.20.00 specifically covers synthetic opium alkaloids and their derivatives that do not fit into the preceding, more narrowly defined categories. This serves as a residual classification for synthetic compounds that share the core structural characteristics of opium alkaloids.

As this is a leaf node, there are no further subcategories within HTS Code 2939.19.20.00. Classification into this code relies on confirming the synthetic nature of the substance and its derivation from or structural similarity to opium alkaloids, while ensuring it does not meet the criteria for any other HTS code at the 8-digit or 10-digit level. Practical classification often involves detailed chemical analysis to verify the synthetic origin and the specific chemical structure of the product in question.
