HS Code for Alfentanil

Alfentanil is classified under Harmonized System (HS) code 2933.33. This classification is based on its chemical structure as a heterocyclic compound containing an unfused pyridine ring. The subheading 2933.33 specifically enumerates several pharmaceutical substances that share this structural characteristic, including alfentanil (INN), anileridine (INN), and others. The explicit mention of alfentanil by its International Nonproprietary Name (INN) within the HS description ensures its precise and unambiguous classification. This placement within Chapter 29 signifies that alfentanil is being classified as a distinct, pure organic chemical compound, rather than a pharmaceutical preparation.

Products Included

Common Misclassification

Alfentanil can be subject to misclassification, primarily with other nitrogen-heterocyclic compounds or pharmaceutical preparations. A common point of confusion might be with HS code 2933.39, which covers "Other" compounds containing an unfused pyridine ring in the structure, not specified elsewhere. The key differentiator for 2933.33 is the explicit listing of alfentanil and other specific INN substances. Another potential misclassification could be with pharmaceutical preparations of Chapter 30 (e.g., 3004). However, Chapter 29 is reserved for pure, unmixed chemical compounds, while Chapter 30 covers medicaments, which are typically formulated preparations containing active pharmaceutical ingredients. Therefore, pure alfentanil, as a chemical substance, remains in 2933.33, whereas a finished pharmaceutical product containing alfentanil would be classified in Chapter 30.

FAQ

What is the HS code for Alfentanil?

The HS code for Alfentanil is 2933.33, which covers heterocyclic compounds containing an unfused pyridine ring in the structure, specifically listing alfentanil (INN) among others.

What does 'INN' signify in chemical classification?

INN stands for International Nonproprietary Name. It is a unique, globally recognized generic name assigned to pharmaceutical substances by the World Health Organization (WHO). Its inclusion in HS descriptions, such as for alfentanil, provides a standardized and unambiguous identification for active pharmaceutical ingredients, facilitating consistent classification and international trade.
