Import Tips
• Obtain API or ASTM certifications to prove pressure rating compliance and avoid reclassification
• Declare exact dimensions and steel grade; pitfalls include incorrect OD measurement leading to wrong subheading
• For refinery use, note any special coatings but ensure they don't alter tube classification
