Import Tips
• Include hydrostatic test reports proving seamless integrity; customs often requires proof against welded tube classifications
• Label spools clearly with OD, wall thickness, and 'refined copper' to match statistical reporting suffixes
• Avoid bundling with fittings—pure tubing only; sets may classify under 7418 as tube fittings
