HS-6 · Subheading
730711
Cast iron; cast fittings, of non-malleable cast iron
Heading 7307 — Tube or pipe fittings (e.g. couplings, elbows, sleeves), of iron or steel
Chapter 73: Articles of iron or steel
Plain-language overview
Use HS-6 730711 when importing or exporting cast fittings made from non-malleable cast iron, such as couplings and elbows. For example, if you are shipping a batch of cast iron elbows for plumbing systems, this code will apply.
This code specifically covers fittings that are cast from non-malleable iron, differentiating them from similar fittings made from malleable iron or other materials. If you have cast iron fittings that are malleable, you would need to look at HS-6 730721 instead.
The 730711 classification is part of a broader category of tube and pipe fittings under HS-4 7307, which includes various types of fittings made from iron or steel. Understanding this distinction is crucial for accurate customs declarations.
When considering whether to use this code, think about the specific characteristics of your product. If your fittings are designed for high-pressure applications or specific industrial uses, ensure they meet the criteria for non-malleable cast iron.
