2934.92.00.00 - Other fentanyls and their derivatives

This HTS category, 2934.92.00.00, specifically covers "Other fentanyls and their derivatives." It falls under the broader heading of "Other heterocyclic compounds" within Chapter 29 of the Harmonized Tariff Schedule, which deals with organic chemicals. This classification is intended for fentanyl analogues and related compounds that are not explicitly listed or covered by other more specific subheadings within the 2934.91 designation.

The distinction between this category and its sibling, 2934.91.00.00, is crucial for accurate classification. While 2934.91.00.00 enumerates specific named compounds (such as aminorex, brotizolam, and sufentanil) and their salts, 2934.92.00.00 is reserved for any other fentanyl derivatives or related substances that do not fit the precise descriptions in the preceding subheading. The key differentiator lies in the explicit naming and inclusion of specific compounds versus the broader, residual nature of this classification for other fentanyl-related substances.

As a leaf node within the HTS structure, this category does not have further subcategories. Therefore, the classification of goods under 2934.92.00.00 relies on a thorough understanding of the definition of "fentanyls and their derivatives" and ensuring that a substance is not specifically enumerated or classifiable elsewhere. This often involves scientific identification and careful consideration of the chemical structure and pharmacological properties to confirm it falls within the scope of "other" fentanyl compounds.
