U.S. imports of mixed-halogen acyclic hydrocarbon derivatives (two or more different halogens, nesoi) (HS 290379) totaled $3.7M in June 2026, traded with 6 countries.
Importers of Mixed-Halogen Acyclic Hydrocarbon Derivatives (Two or More Different Halogens, NESOI) paid $274K in duties in June 2026 — an effective duty rate of 7.3% on $3.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Mixed-Halogen Acyclic Hydrocarbon Derivatives (Two or More Different Halogens, NESOI) imports of $3.7M in June 2026 ran 16% below the year-to-date monthly average of $4.5M.
Bromochloromethane (line 2903791000) and the broader NESOI lines (2903799000 and 2903799070) cover acyclic hydrocarbon derivatives bearing two or more different halogens — a chemically diverse group that includes flame-retardant intermediates, pharmaceutical building blocks, and agrochemical precursors. India and Japan are the leading US suppliers, with China, Mexico, and Canada rounding out the top sources, reflecting both large-scale Asian chemical manufacturing and North American integrated supply chains. The breadth of this residual category means classification disputes are common when a compound could plausibly fit a more specific heading.

The specific HCFC and CFC headings (290373–290377) take precedence for named compounds meeting their descriptions. Heading 290379 applies to acyclic derivatives with two or more different halogens that are not perhalogenated (which would go to 290378) and do not match any named compound in the earlier headings. The key classification steps are confirming the degree of halogenation and checking whether the compound is specifically enumerated elsewhere in Chapter 29.
Bromochloromethane is listed as an ozone-depleting substance under the Montreal Protocol, so EPA allowance requirements may apply depending on the intended use and quantity. Importers should confirm current EPA regulatory status before shipment, as the compliance framework can differ from the more widely known CFC/HCFC allowance system.
