Product classification
HS code for Industrial waste: 3825.90
Residual products of the chemical or allied industries, not elsewhere specified or included, n.e.c. in 3825 or 27.10.
Classification of industrial waste under HS 3825.90
HS code 3825.90 is a critical classification for the environmental and chemical industries, covering residual products of the chemical or allied industries not elsewhere specified. This code is used for complex waste streams that do not fit into more specific categories like waste oils or clinical waste. Classification here requires that the material be a residual product—meaning it is no longer fit for its original intended use and is destined for disposal, incineration, or recycling. This often includes chemical sludges, spent catalysts that do not contain precious metals, and various by-products from manufacturing processes that lack a dedicated heading. The classification is determined by the chemical composition and the origin of the waste. Because this is a residual "other" category, it is only used when the waste cannot be classified under headings 3825.10 through 3825.69 or within the specific fuel-related codes of Chapter 27.

Codes often confused with 3825.90
Common mistake. A frequent error is classifying waste oils under 3825.90, whereas they must be classified under 2710.91 or 2710.99. Waste organic solvents are also often misplaced here but should be under 3825.41 or 3825.49. Additionally, if the waste contains primarily precious metals for recovery, it must be classified under 7112. It is vital to check the specific subheadings of 3825 before defaulting to the 3825.90 residual code.
Top exporters and importers of HS 382590 (the code used for industrial waste), 2025
In 2025, the largest exporter of HS 382590 (the code used for industrial waste) in UN Comtrade data was the United States, with 21% of world exports; the largest importer in UN Comtrade data was Ukraine, with about 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
