Import Tips

Verify residue composition via lab analysis to confirm it meets 'residues of petroleum oils' definition and obtain Certificates of Analysis

Ensure proper hazardous material declarations (e.g

IMDG for shipping) as these residues often contain hazardous hydrocarbons

Avoid misclassification as waste; provide evidence of commercial value and reprocessing intent to prevent EPA scrutiny
