Import Tips

Submit detailed blend composition certificates showing biodiesel percentage and petroleum base to validate 70%+ oil content requirement

Comply with MARPOL Annex VI sulfur limits (<3.5% for global trade) with test reports to facilitate smooth CBP clearance

Avoid misdeclaration as lighter distillates by including flash point (>60°C) and viscosity specs in entry documentation
