Import Tips

• Obtain material test reports (MTRs) certifying alloy composition and seamless manufacturing to comply with HTS 7304 requirements

• Verify exact OD (190.5-285.8 mm) and wall thickness (12.7-19 mm) measurements per ASTM specs to avoid misclassification

• Include end-user certificates if for pressure applications to prevent reclassification as tubes under different headings
