Import Tips

Provide Safety Data Sheets (SDS) and ensure UN proper shipping name documentation for hazardous material compliance

Verify purity certificates to confirm it meets 'chemically defined' criteria under Chapter 29 notes

Avoid misclassification as a refrigerant gas (HTS 2903) if not meeting acyclic alcohol derivative specs
