2903.82.00.00 - Aldrin (ISO), chlordane (ISO) and heptachlor (ISO)

This HTS category, 2903.82.00.00, specifically covers the organochlorine pesticides Aldrin, Chlordane, and Heptachlor. These are highly chlorinated cyclic hydrocarbons that were widely used as insecticides. Their classification here is based on their chemical structure and their identification by the International Organization for Standardization (ISO) with these specific names. This section of the tariff schedule is dedicated to halogenated derivatives of hydrocarbons, and this particular subheading isolates these specific, potent compounds.

It is important to distinguish this category from its siblings. HTS 2903.81.00.00 covers 1,2,3,4,5,6-Hexachlorocyclohexane (HCH), also known as Lindane, which is a distinct chemical compound with a different structural formula and isomer composition. Similarly, HTS 2903.83.00.00 is reserved for Mirex, another organochlorine insecticide with a unique polycyclic structure. Category 2903.89.00.00 serves as a residual category for other halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons that do not fit into the more specific subheadings.

As a leaf node within the HTS classification system, 2903.82.00.00 has no further subdivisions. Classification into this specific code relies on the definitive identification of the imported or exported substance as Aldrin, Chlordane, or Heptachlor, often confirmed through chemical analysis or documented product specifications. These substances are recognized for their past widespread agricultural and industrial applications.
