Import Tips

• Verify sulfur content via ASTM D129 or equivalent testing to confirm >500 ppm and avoid reclassification to low-sulfur subheadings

• Provide detailed refinery certificates and biodiesel blend ratios (70%+ petroleum oils) for customs clearance

• Ensure proper storage tank declarations to prevent mixing with low-sulfur fuels during import
