Import Tips
• Verify burst pressure certification through testing to confirm classification under 3917.31; lower pressure shifts to 3917.39
• Provide material composition docs showing predominant polymer (e.g
• polyamide >95%) per Chapter 39 notes
• Avoid common pitfalls like mislabeling as rigid tubing, which falls under 3917.29
