Tubes, pipes and hollow profiles, of cast iron
In plain English
This category covers tubes, pipes, and hollow profiles made from cast iron. The classification system places all such items under a single entry without further subdivision. Consequently, there are no additional levels of detail to distinguish between different types of these specific products.
6-digit subheadings (1)
Official HS 2022 subheading texts. National tariff schedules subdivide these further (8-10 digit lines) and set the actual duty rates.

Chapter 73 classification notes
Frequent misclassification in this chapter
Stainless steel articles should be classified under the specific stainless steel headings, not general iron/steel. Alloy steel has its own subheadings.
Classification certainty
The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
