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
