Import Tips
• Verify vehicle compatibility certification to confirm classification under 8409.99.91.90; mismatch leads to reclassification
• Provide engine model and vehicle subheading documentation to Customs for smooth clearance
• Avoid common pitfall of classifying as general auto parts under 8708 without proving principal use with 8407/8408 engines
