9902.01.76 - Ytterbium trifluoride powder (CAS No. 13760-80-0) with a median particle size of greater than 0.2 microns and less than 0.7 microns (provided for in subheading 2846.90.80)

HTS code 9902.01.76 specifically covers ytterbium trifluoride powder with precisely defined particle size characteristics. This entry is for a specialized chemical compound, identified by its CAS number 13760-80-0, where the median particle size is established to be greater than 0.2 microns and less than 0.7 microns. This precise granulometry is the critical factor for its classification under this provision, distinguishing it from other forms of ytterbium trifluoride or other rare earth compounds.

This classification exists within Chapter 99, which is dedicated to temporary legislation, modifications pursuant to trade agreements, and additional import restrictions. Therefore, its purpose is to manage or monitor imports of this specific material, likely due to trade policy, national security, or specific economic considerations. It is important to note that this provision is a "provided for" classification, meaning the base tariff treatment of ytterbium trifluoride is found under subheading 2846.90.80, and this Chapter 99 code imposes an additional or specific condition for importation.

As this is a leaf node within the HTS database, there are no further subcategories under 9902.01.76. The classification is complete at this level, with the product defined by its chemical identity and precise physical characteristics. Importers must ensure that their shipment of ytterbium trifluoride powder meets the specified median particle size range to correctly utilize this classification and comply with all applicable trade regulations.
