SA-213 TP347H Seamless Boiler Tube from Japan
Seamless tube made from TP347H stabilized austenitic stainless steel alloy, with an outside diameter of 250 mm, designed specifically for high-temperature superheaters in industrial boilers. It falls under HTS 7304.59.20.60 due to its seamless construction, circular cross-section, alloy steel composition, and suitability for superheaters with the specified diameter range. These tubes withstand extreme pressures and temperatures in power generation.

Import Tips
• Verify material certification to ASTM A213/ ASME SA-213 standards proving alloy composition and seamless production; obtain end-user declarations confirming boiler/superheater use to avoid reclassification; watch for diameter measurement discrepancies during customs inspection
