3825.61.00.00 - Mainly containing organic constituents 🖩

This HTS subheading, 3825.61.00.00, specifically addresses residual products from the chemical and allied industries that are primarily composed of organic constituents. These are generally waste materials generated during chemical manufacturing processes or the production of allied industries, where the organic component significantly outweighs any inorganic elements. Examples may include spent organic catalysts, organic residues from the processing of natural products, or mixtures of organic by-products that have no other specific classification. The key criterion for inclusion is the predominantly organic nature of the waste.

This category is distinguished from its sibling, 3825.69.00.00 ("Other"), which covers residual products from the chemical or allied industries that are not mainly organic. If a waste product from these industries contains a significant inorganic component or is primarily inorganic in nature, it would fall under the "Other" category. The determination of "mainly containing organic constituents" is crucial for correct classification.

As this subheading is a leaf node in the HTS classification, there are no further subdivisions under 3825.61.00.00. Therefore, classification decisions at this level rely on accurately identifying the waste as originating from the chemical or allied industries and confirming that its primary composition is organic. When in doubt, reference to Section VI, Chapter 38, and Note 6 to Chapter 38 of the Harmonized Tariff Schedule of the United States, as well as any relevant interpretive notes, is recommended.
