A specialized fire suppression blend containing hydrobromofluorocarbon HBFC-123B1 (C2HBrF4) mixed with inert propellants for use in clean agent fire extinguishers. This mixture falls under HTS 3827.12.00.00 because it primarily contains HBFCs, which are halogenated derivatives of ethane used in controlled industrial applications. It is subject to strict import regulations due to ozone-depleting properties.

Import Tips

• Obtain EPA approval under the Montreal Protocol Clean Air Act for all HBFC imports; provide Substance Protection Authorization

• Include detailed chemical composition certificates and end-use statements to avoid customs holds on restricted substances

• Verify Phase II exemption status as HBFCs are almost fully banned; common pitfall is missing TSCA import certification
