Overview
This HTS category, 9902.16.21, specifically classifies Lithium Thionyl Chloride (LTC) batteries that meet a precise set of physical and compositional criteria. These batteries are annular in shape and are further defined by their dimensions, requiring specific minimum and maximum lengths (30.48 mm to 152.4 mm), outer diameters (10.16 cm to 127 mm), and inner diameters (55.88 mm to 88.9 mm). Crucially, importers must certify that these batteries contain a lithium anode and a liquid cathode composed of porous carbon filled with thionyl chloride (SOCl2). This detailed description ensures that only very specific types of these specialized batteries are captured under this heading.
This temporary legislation provision is distinct from the broader categories typically found in the Harmonized Tariff Schedule, such as those covering live animals (Chapters 01) or general manufactured goods. Its placement within Chapter 99 indicates it is subject to temporary modifications, trade agreement legislation, or additional import restrictions, rather than a permanent tariff classification. Unlike standard battery classifications under Chapter 85 (e.g., subheading 8507.60.00, which is referenced as the primary classification for these batteries when not subject to the temporary measures), this 9902 code applies only under specific, declared circumstances and is not a default classification.
As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is definitive based on the detailed physical and chemical parameters outlined in the description. Therefore, the focus for classification purposes is on verifying adherence to all specified dimensions and the importer's certification regarding the battery's internal composition, ensuring compliance with the specific temporary provisions governed by this HTS code.
