Import Tips

Verify the steel is nonalloy (less than 10% alloying elements) via mill test certificates to avoid reclassification

Ensure threading specifications match US standards (e.g

NPT) to comply with plumbing codes and prevent customs holds

Declare exact dimensions and galvanization process; anti-dumping duties may apply to certain galvanized steel products from specific countries
