Import Tips
• Verify ASTM A178 certification and wall thickness ≥1.65mm to confirm HTS 7306.30.50.10 classification; thinner walls shift to 7306.30.30
• Provide end-use documentation proving boiler suitability to avoid reclassification as general pipe under 7306.19
• Ensure hydrostatic test certificates for pressure applications to meet boiler code compliance
