9902.01.91 - 2-Chlorobenzyl chloride (CAS No. 611-19-8) (provided for in subheading 2903.99.80)

This HTS category, 9902.01.91, specifically classifies 2-Chlorobenzyl chloride (CAS No. 611-19-8). This compound is a chlorinated organic chemical used as an intermediate in the synthesis of various chemicals, pharmaceuticals, and agricultural products. Its classification is explicitly linked to its intended use as a precursor, as indicated by the parenthetical reference to subheading 2903.99.80, which covers other chlorinated derivatives of aromatic hydrocarbons.

Unlike the broad array of live animals found in the sibling categories under Chapter 99, or other general chemical classifications, this specific entry is for a highly defined chemical substance with a designated CAS number. The "9900" series of HTS codes is reserved for special classification provisions, temporary legislation, and temporary modifications, often related to specific trade agreements or temporary import restrictions. Therefore, this category is distinct from standard chemical headings that might cover finished goods or chemicals with broader industrial applications.

As a leaf node, this HTS category has no further subdivisions. The classification is precise and intended to capture 2-Chlorobenzyl chloride itself, or potentially its specific forms or purities if not explicitly distinguished elsewhere. Importers must ensure the chemical identity and CAS number precisely match to correctly apply this provision, recognizing its special tariff treatment under temporary legislation.
