Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for boiler/pressure vessel service
Boiler tubes classify under 7304.51 based on high-temp/pressure end-use, not oil/gas transport.
If welded construction of similar specs
Equivalent welded versions fall under 7306.19 line pipe heading due to manufacturing difference.
If sold as set with welded fittings
Assembled pipe sets with fittings may classify under 7304.90 as composite articles.
