Import Tips

Verify alloy certification with mill test reports confirming Mo (1.5-5%) and Ni (>0.5-24%) content to avoid reclassification

Ensure wall thickness documentation exceeds 1.65 mm; common pitfall is mismeasurement leading to duty disputes

Label as 'welded' explicitly; provide weld seam inspection records for customs compliance
