HS code for 1,1,1-Trichloroethane mixtures: 3827.14
Mixtures containing halogenated derivatives of methane, ethane or propane, not elsewhere specified or included, containing 1,1,1-trichloroethane (methyl chloroform).
Classification of 1,1,1-Trichloroethane mixtures under HS 3827.14
Mixtures containing 1,1,1-trichloroethane, also known as methyl chloroform, are classified under HS code 3827.14. This classification is part of Chapter 38, which covers miscellaneous chemical products. Heading 3827 was introduced in the 2022 HS nomenclature to specifically group mixtures containing halogenated derivatives of methane, ethane, or propane. These substances are strictly monitored under the Montreal Protocol due to their ozone-depleting potential. For a product to be classified under 3827.14, it must be a mixture where 1,1,1-trichloroethane is a constituent part. This applies to industrial solvents, degreasing agents, or chemical blends where the substance is not a single chemically defined compound. If the product were a pure, single chemical compound, it would be classified in Chapter 29. The inclusion of 1,1,1-trichloroethane in this specific subheading ensures that customs authorities can track and regulate the movement of this controlled substance effectively, regardless of the other components in the mixture.
- Covers
- Solvent mixtures containing 1,1,1-trichloroethane
- Degreasing preparations with methyl chloroform
- Chemical blends for metal cleaning containing 1,1,1-trichloroethane
- Industrial cleaning solutions with halogenated ethane derivatives
- Also under 3827.14
- N/A (virtually no consumer products)
- historically used by companies like Dow Chemical for industrial solvents.
Codes often confused with 3827.14
Common mistake. The most common misclassification is under HS code 2903.19, which is for pure 1,1,1-trichloroethane. Another error is using 3824.99, the general basket code for chemical products, which is incorrect because heading 3827 is more specific for halogenated mixtures. Additionally, mixtures containing other halogenated solvents like trichloroethylene (3827.13) are sometimes confused with 3827.14.
Top exporters and importers of HS 382714 (the code used for 1,1,1-Trichloroethane mixtures), 2025
In 2025, the largest exporter of HS 382714 (the code used for 1,1,1-Trichloroethane mixtures) in UN Comtrade data was Austria, with 70% of world exports; the largest importer in UN Comtrade data was Austria, with 50% of world imports. Mexico reports $159M of its heading 3827 imports without product detail (confidential), so it may also belong among the top importers.

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).
