Import Tips
• Certify durometer hardness (e.g
• 70-90 Shore A) in tech data sheets for classification verification
• Avoid common pitfall of misdeclaring as 'parts of Chapter 87' which requires specific vehicle fitment proof
• Use HTSUS advisory rulings for custom O-rings to preempt CBP disputes on automotive specificity
