Import Tips
• Label with schedule designation and confirm wall thickness via caliper or NDT to match tariff specs exactly
• For Schedule 10S, ensure not mistaken for thinner Schedule 5 (under 1.65 mm wall) which would be 7306.40.51
• Provide evidence of ERW (electric resistance welded) process if audited, as it affects 'welded' classification
