Import Tips
• Verify sulfur content via ISO 20846/20884 testing and provide certificates to CBP for ≤500 ppm compliance
• Ensure documentation proves ≥70% petroleum oil content and biodiesel as basic constituent per Chapter 27 notes
• Beware reclassification if viscosity exceeds 125 SUS (may shift to 2710.20.10.25) or sulfur >500 ppm
