2939.19 - Other:

This HTS category, 2939.19, covers "Other" alkaloids of opium and their derivatives, along with their salts, that are not specifically listed under the sibling category 2939.11. It encompasses a broad range of naturally occurring or synthetically reproduced alkaloids derived from opium, excluding those explicitly enumerated such as morphine, codeine, and their immediate derivatives. The primary distinguishing factor for goods classified here is their chemical structure and origin, falling within the broader family of opium alkaloids but not fitting the precise descriptions of the more specific subheadings.

The exclusion of specific, widely recognized opium alkaloids and their salts from this category is deliberate. For instance, while buprenorphine, codeine, and morphine are clearly defined under 2939.11, this residual category ensures that other compounds with similar pharmacological or chemical characteristics, yet not named individually, are correctly classified. This approach is crucial for maintaining the integrity and accuracy of customs declarations, preventing misclassification and ensuring compliance with trade regulations.

Under this residual category, further subdivisions exist to provide more granular classification. The primary subcategory, 2939.19.10.00, specifically addresses Papaverine and its salts. Papaverine, another alkaloid found in opium, has distinct chemical properties and therapeutic uses compared to the substances in 2939.11, thus warranting its own subheading. Any other opium alkaloid derivatives or their salts not fitting this specific Papaverine subheading or the more general sibling category would then fall into the remaining "Other" designation within this HTS code, necessitating detailed chemical analysis for precise classification.
