Product classification
HS code for Halogenated waste solvents: 3825.41
Residual products of the chemical or allied industries, not elsewhere specified or included, halogenated waste organic solvents.
Classification of halogenated waste solvents under HS 3825.41
Halogenated waste organic solvents are classified under HS code 3825.41. This code is part of heading 3825, which covers residual products of the chemical or allied industries, not elsewhere specified or included. The classification specifically targets \"waste\" materials, meaning products that are no longer fit for their original intended use, often recovered from industrial processes or cleaning operations. The distinction of being \"halogenated\" refers to the presence of chlorine, fluorine, bromine, or iodine within the organic solvent molecules. Under the Harmonized System, waste organic solvents are categorized separately from pure chemical compounds (Chapter 29) because they are typically complex mixtures of various substances and contaminants resulting from their industrial application. GRI 1 dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Note 6 to Chapter 38 specifically defines waste organic solvents, ensuring they are classified here rather than as chemical mixtures under heading 3824. This classification is vital for environmental compliance and the tracking of hazardous materials across international borders, as halogenated wastes often require special handling and disposal protocols.

Codes often confused with 3825.41
Common mistake. The most common misclassification occurs with HS code 3825.49, which is reserved for non-halogenated waste organic solvents. Importers must verify the halogen content through laboratory analysis. Another error is attempting to classify these wastes under Chapter 29 (e.g., 2903) as pure chemicals; however, once a chemical is used and becomes a waste stream, it must be classified under heading 3825.
Top exporters and importers of HS 382541 (the code used for halogenated waste solvents), 2025
In 2025, the largest exporter of HS 382541 (the code used for halogenated waste solvents) in UN Comtrade data was Switzerland, with 64% of world exports; the largest importer in UN Comtrade data was France, with 64% 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).

Questions about halogenated waste solvents
What is the HS code for Halogenated waste solvents?
The HS code for Halogenated waste solvents is 382541 (Residual products of the chemical or allied industries, not elsewhere specified or included; halogenated waste organic solvents). The HS code for halogenated waste organic solvents is 3825.41.
How do I classify Halogenated waste solvents for customs?
Halogenated waste solvents is classified under HS code 382541 — Residual products of the chemical or allied industries, not elsewhere specified or included; halogenated waste organic solvents. This is a 6-digit subheading level code.
When should I use 3825.41 instead of 2903?
Use 3825.41 when the product is a waste material or residual product from an industrial process. Chapter 29 (specifically 2903) is reserved for separate, chemically defined compounds that are not waste.
Which countries are the top exporters of halogenated waste solvents (HS 382541)?
In 2025, the top exporters of HS 382541 (the code used for halogenated waste solvents) in UN Comtrade data were Switzerland ($911K, 64% of world exports), Jordan (about $234K) and Belgium ($118K). World exports came to about $1.4M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of halogenated waste solvents (HS 382541)?
In 2025, the top importers of HS 382541 (the code used for halogenated waste solvents) in UN Comtrade data were France ($1.8M, 64% of world imports), Germany ($562K) and South Korea ($119K). World imports came to about $2.9M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Halogenated waste solvents the same in all countries?
