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
