Last updated: April 2026 dataClassified under tariff line 3825900100, this residual heading captures wastes that qualify under the definitional criteria of Note 6 to Chapter 38 but do not fall within any of the more specific waste headings (382510–382569). Note 6 defines the scope of Chapter 38 waste headings by reference to specific characteristics — such as being unfit for original use, generated as a by-product, or not usable without prior reprocessing — making precise note analysis essential before defaulting to this heading. Importers dealing with novel or mixed waste streams that resist classification elsewhere in Chapter 38 should document the Note 6 analysis carefully to support the classification at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Note 6 to Chapter 38 defines the conditions under which a substance qualifies as a 'waste' for purposes of headings 3825 and related provisions — typically requiring that the material be unfit for its original use, generated as a by-product of a manufacturing process, or not usable without prior reprocessing. Only materials that satisfy those criteria and do not fit a more specific heading in 3825 are properly classified under 382590.
The importer should retain the Note 6 analysis showing why the material qualifies as a Chapter 38 waste, evidence that each more specific heading (382510–382569) was considered and ruled out, and supporting technical documentation such as a composition analysis or process description. A binding ruling request to CBP is advisable for recurring shipments of unusual waste streams.
