Overview
HTS Code 9902.02.07 specifically classifies Triflic anhydride, also known as trifluoromethanesulfonic anhydride (CAS No. 358-23-6). This substance is a powerful triflating agent used primarily in organic synthesis for laboratory and industrial chemical processes. Its inclusion within Chapter 99 signifies a temporary or special classification provision, indicating it is subject to specific import regulations or modifications beyond its standard classification under the main HTS structure.
Unlike the broad range of live animals found in other sibling categories such as Chapter 01, this node is highly specific, focusing on a single chemical compound. Its purpose as a specialized reagent for chemical reactions clearly differentiates it from general merchandise or raw materials. The provision "provided for in subheading 2904.99.50" further contextualizes its primary chemical classification, highlighting that this Chapter 99 entry represents an overlay of specific trade or regulatory treatment for this particular chemical.
As this node is a leaf node, there are no further subcategories. Classification under 9902.02.07 is definitive for triflic anhydride when imported under the specific circumstances triggering this special provision. Importers should verify the conditions that necessitate classification under this temporary legislation or modification, which may include quotas, duties, or specific reporting requirements.
