Product classification
HS code for Halogenated mixtures: 3827.90
Mixtures containing halogenated derivatives of methane, ethane or propane, n.e.c. in subheading no 3827.
Classification of halogenated mixtures under HS 3827.90
Halogenated mixtures are classified under HS code 3827.90. This code was introduced in the 2022 HS nomenclature update to better track and regulate mixtures containing halogenated derivatives of methane, ethane, or propane, which are often used as refrigerants, solvents, or fire extinguishants. Chapter 38 covers miscellaneous chemical products, and heading 3827 specifically addresses mixtures containing hydrofluorocarbons (HFCs) or perfluorocarbons (PFCs) but not containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). Subheading 3827.90 is the residual category for mixtures that do not meet the specific criteria of the more defined subheadings (3827.11 through 3827.69). These mixtures are typically complex blends of various halogenated hydrocarbons designed for specific industrial thermal properties. The classification is driven by the chemical composition of the mixture rather than its end-use, though many are found in the HVAC and fire protection industries. Proper documentation of the chemical constituents is essential for correct classification under this heading.

Codes often confused with 3827.90
Common mistake. A common mistake is classifying these mixtures under heading 2903. Heading 2903 is strictly for chemically defined pure halogenated derivatives; as soon as two or more such substances are mixed for a specific use, the product moves to Chapter 38. Another error is using 3824.99, which was the previous catch-all for chemical mixtures. With the 2022 update, most halogenated mixtures must now be in 3827. Additionally, fire extinguisher preparations already put up in charges or extinguishers should be classified under 3813.00 rather than 3827.90.
Top exporters and importers of HS 382790 (the code used for halogenated mixtures), 2025
In 2025, the largest exporter of HS 382790 (the code used for halogenated mixtures) in UN Comtrade data was the United States, with 34% of world exports; the largest importer in UN Comtrade data was Thailand, with 38% 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 that did not report are estimated from what other countries recorded trading with them. 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 mixtures
What is the HS code for Halogenated mixtures?
The HS code for Halogenated mixtures is 382790 (Mixtures containing halogenated derivatives of methane, ethane or propane; n.e.c. in subheading no 3827). The HS code for mixtures containing halogenated derivatives of methane, ethane, or propane (not elsewhere specified) is 3827.90.
How do I classify Halogenated mixtures for customs?
Halogenated mixtures is classified under HS code 382790 — Mixtures containing halogenated derivatives of methane, ethane or propane; n.e.c. in subheading no 3827. This is a 6-digit subheading level code.
Does 3827.90 include mixtures with CFCs?
No, mixtures containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs) are classified in the earlier subheadings of 3827 or under heading 3824, depending on the specific composition.
Which countries are the top exporters of halogenated mixtures (HS 382790)?
In 2025, the top exporters of HS 382790 (the code used for halogenated mixtures) in UN Comtrade data were the United States ($6.4M, 34% of world exports), Germany ($5.8M) and the Netherlands ($1.1M). World exports came to about $19M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).
