Import Tips

Verify seamless construction via mill test certificate; welded tubes classify under 7305/7306

Provide material composition analysis to confirm 'other alloy steel' (e.g

>1.65% Mn or specific alloying elements)

Measure OD precisely (190.5-285.8 mm range) and wall thickness (<12.7 mm) to match statistical suffix
