Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of iron or non-alloy steel construction
Standard carbon steel casing classifies under 7304.23 rather than stainless steel provisions.
If outside diameter not exceeding 285.8 mm
Smaller OD stainless casing falls in 7304.24.20 series despite identical wall thickness.
If imported in screw-threaded lengths exceeding 3 meters
Heavy-walled stainless tubes primarily for screw-threading applications may classify under other hollow profiles.
