Import Tips
• Submit heat analysis reports confirming carbon content <0.3% to prove non-alloy status
• Avoid bundling with fittings; sets may classify under 7307 as tube fittings rather than individual pipes
• Check for anti-dumping orders on specific grades/sources; Chinese A106 often under AD/CVD scrutiny
