Import Tips
• Document tank cleaning records and clarification process to prove it's a petroleum residue, not waste
• Check flash point and viscosity specs; residues below certain thresholds may shift to 2710 classifications
• Use NIOSH-approved containers for transport due to potential H2S content in these residues
