HS code · 6-digit subheading
HS Code 2903.78 – Halogenated derivatives of acyclic hydrocarbons containing two or more different halogens; perhalogenated derivatives, other than those only with fluorine and chlorine, n.e.c. in item no. 2903.71 to 2903.76
HS code 2903.78 is the 6-digit subheading for halogenated derivatives of acyclic hydrocarbons containing two or more different halogens, perhalogenated derivatives, other than those only with fluorine and chlorine, n.e.c. in item no. 2903.71 to 2903.76. It is used for perfluorobromoethane, perfluorochloroiodomethane, perfluorobromopropane, perfluorochlorobromomethane and specialty perhalogenated compounds.
What HS 2903.78 covers
This is a broad 'basket' category for perhalogenated acyclic hydrocarbons containing two or more different halogens, specifically excluding those composed solely of fluorine and chlorine, and not specifically listed in subheadings 2903.71 to 2903.76. This encompasses a diverse range of compounds that might contain bromine or iodine in addition to fluorine and/or chlorine, and are fully halogenated. These chemicals often find applications as specialty solvents, chemical intermediates in advanced synthesis, or in niche areas requiring unique chemical properties, though many are subject to environmental regulations due to their ozone-depleting potential or global warming potential. Trade involves specialized chemical manufacturers, research and development institutions, and industries requiring unique solvent properties or precursors for high-value products.

Codes often confused with 2903.78
Common mistake. Can be confused with other halogenated derivatives, especially those containing only fluorine and chlorine (2903.77), or with non-perhalogenated compounds, requiring careful verification of the 'perhalogenated' and 'other than only fluorine and chlorine' criteria.
Top exporters and importers of HS code 290378, 2025
In 2025, the largest exporter of HS code 290378 in UN Comtrade data was Japan, with 66% of world exports; the largest importer in UN Comtrade data was the United States, with 25% 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).

What are common misclassifications for HS code 290378?
Can be confused with other halogenated derivatives, especially those containing only fluorine and chlorine (2903.77), or with non-perhalogenated compounds, requiring careful verification of the 'perhalogenated' and 'other than only fluorine and chlorine' criteria.
Which countries are the top exporters of goods under HS code 290378?
In 2025, the top exporters of HS code 290378 in UN Comtrade data were Japan ($26M, 66% of world exports), the United States ($12M) and India ($491K). World exports came to about $40M, 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.
