9902.03.12 - Propyl 3,4,5-trihydroxybenzoate (Propyl gallate) (CAS No. 121-79-9) (provided for in subheading 2918.29.75)

This HTS category, 9902.03.12, pertains to a specific chemical compound: Propyl 3,4,5-trihydroxybenzoate, commonly known as Propyl gallate (CAS No. 121-79-9). This substance is primarily recognized for its antioxidant properties and is often used as a food additive to prevent spoilage. While its primary use is as a preservative, the classification itself focuses on the chemical identity rather than the end-product in which it might be incorporated.

Category 9902.03.12 functions as a special provision within Chapter 99 of the Harmonized Tariff Schedule, indicating temporary legislation or modifications. This means that while the substance itself might otherwise be classified under a different chapter (as indicated by its provision in subheading 2918.29.75), it is subject to specific import regulations or considerations under this temporary tariff. This distinguishes it from goods classified under the permanent chapters of the HTS, which do not carry such temporary legislative overlays.

As a leaf node, this HTS code does not have further subcategories. Classification into 9902.03.12 is definitive for Propyl gallate when imported under the specific conditions outlined by the temporary legislation. Importers should verify any associated duties, restrictions, or documentation requirements linked to this special classification provision, as these are the defining characteristics that differentiate it within the broader HTS framework.
