Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If OD not exceeding 285.8 mm
Smaller diameters shift to adjacent subheading 7304.59.40 within the same boiler-suited other alloy category.
If for industrial non-boiler heat exchanger use only
Hollow profiles not explicitly for boilers may go to 7228 for alloy steel bars/tubes of other than circular section or general use.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Supply ultrasonic test reports for internal soundness; ensure 'seamless' marking on bundles; common error: classifying smaller OD under wrong statistical break
