Import Tips
• Verify sulfur content via ISO 8754 or ASTM D4294 testing and include certificates in documentation
• Ensure viscosity and API gravity specs match exactly to avoid reclassification to higher subheadings
• Common pitfall: blending errors exceeding 500 ppm sulfur leading to duty adjustments
