7304.51.50.15/Cold-Drawn Heat-Resisting Steel Boiler Tube/Mexico

Cold-Drawn Heat-Resisting Steel Boiler Tube from Mexico

Seamless cold-drawn tube made from heat-resisting alloy steel, designed for high-temperature applications in steam boilers. Its circular cross-section and cold-rolled finish ensure pressure resistance and durability in superheaters. Classified under 7304.51.50.15 due to its seamless construction, heat-resisting steel composition, and suitability for boilers.

Import Tips

• Verify chemical composition certification to confirm heat-resisting steel (e.g

• ASTM A213 TP347H) meeting Chapter 73 alloy definitions

• Provide mill test reports proving seamless cold-drawn process and pressure ratings for boiler use to avoid misclassification

• Ensure marking complies with ASME Boiler Code; common pitfall is failing to distinguish from hot-finished tubes under 7304.51.30
