2915.40.50 - Other

This HTS category, 2915.40.50, encompasses a specific group of acetic acid derivatives that do not fall under the more precisely defined classifications within heading 2915.40. It broadly covers those compounds derived from acetic acid that are characterized by the presence of one or more chlorine atoms in the acyclic chain, excluding specific mono-, di-, or trichloroacetic acids themselves, as well as their salts and esters which are classified elsewhere. The "Other" designation signifies a residual category for these halogenated acetic acid derivatives.

Distinguishing this category from its siblings, particularly "Aromatic," is crucial for accurate classification. While this subheading focuses on acyclic structures (straight or branched carbon chains), the "Aromatic" sibling would pertain to acetic acid derivatives where the acetic acid moiety is attached to an aromatic ring system. Therefore, the presence or absence of an aromatic ring is the primary differentiating factor at this level.

Within this "Other" category, further subdivisions exist to refine the classification of these compounds. The subcategories, such as 2915.40.50.10 for Sodium chloroacetate and 2915.40.50.50 for other specific substances, allow for more granular identification based on the specific salt or ester form, or other uniquely identifiable derivatives that meet the broader criteria of this heading but warrant distinct treatment. This ensures that the trade flow of diverse chemical compounds is accurately accounted for.
