9902.03.07 - o-Acetylsalicylic acid (Aspirin) (CAS No. 50-78-2) (provided for in subheading 2918.22.10)

This classification, HTS Code 9902.03.07, specifically covers o-Acetylsalicylic acid, more commonly known as Aspirin, identified by CAS Number 50-78-2. It is important to note that this entry is provided for under subheading 2918.22.10, indicating that while Aspirin falls within the broader chemical classifications of Chapter 29, this particular code in Chapter 99 is for special or temporary provisions.

Unlike the numerous sibling categories under Chapter 99 that often relate to temporary trade measures, quotas, or specific import restrictions on a wide array of goods, this code carves out a specific niche for Aspirin, likely due to unique import requirements or temporary tariff modifications associated with it. It is crucial to understand that Chapter 99 codes are dynamic and can be subject to change based on trade agreements and legislative actions, making diligent verification essential.

As this HTS code is a leaf node, there are no further subcategories. Classification under 9902.03.07 is definitive for o-Acetylsalicylic acid (Aspirin) when imported under the specific conditions or provisions designated by this temporary legislation. The primary classification of Aspirin itself remains within its established chemical category under Chapter 29, but this Chapter 99 entry dictates specific procedural or tariff treatment.
