Import Tips

• Provide OPPTS 830 testing data for customs; failure to declare toxicity leads to 100% exam rates

• Secure BIS export license equivalents for import; dual-use chemical with strict end-use monitoring

• Avoid glass packaging—use PFA/PTFE due to HF generation risk, preventing common DOT violation
