9902.10.43 - α-Hydro-ω-hydroxypoly(oxy-1,2-ethanediyl)borate (CAS No. 71243-41-9) (provided for in subheading 3819.00.00)

This HTS category, 9902.10.43, specifically classifies α-Hydro-ω-hydroxypoly(oxy-1,2-ethanediyl)borate, identified by CAS No. 71243-41-9. This substance is a specialized chemical compound, provided for under the broader heading of 3819.00.00, which encompasses preparations and charges for fire extinguishers, whether or not charged; prepared pyrophoric alloys and preparations for igniting any combustible material; and other chemical products and preparations of the chemical or allied industries, not elsewhere specified or included. The inclusion of this specific compound within Chapter 99 signifies its classification under temporary legislation, temporary modifications proclaimed pursuant to trade agreements, or additional import restrictions.

As a leaf node within the Harmonized Tariff Schedule, 9902.10.43 does not have further subdivisions. Its specific nature as a borate compound with a poly(oxy-1,2-ethanediyl) structure differentiates it from other entries within Chapter 99, which are generally dedicated to temporary measures affecting a wide array of goods. This entry is intended for the precise identification and regulation of this particular chemical, rather than broad categories of goods. Its classification is distinct from the primary product categories found in earlier chapters of the HTS (e.g., live animals in Chapter 01), which are based on fundamental product types rather than specific chemical formulations subject to temporary trade provisions.
