Harmonized System Code Classification

HS Code 7307915010
Description: Flanges of iron or non-alloy steel, with an inside diameter of less than 360 mm, other.

Explanation:
This HS code classifies flanges made of iron or non-alloy steel that have an inner diameter less than 360 mm and are categorized as other (not specifically listed elsewhere). Flanges are components used to connect pipes or tubes, typically in piping systems.

Product Examples:
- Steel flange for industrial piping systems
- Iron flange with a 250 mm inner diameter
- Non-alloy steel flange used in water supply systems
- Pipe flange for oil and gas pipelines
- Flange with a 300 mm inner diameter made of carbon steel

Notes:
- This code does not include stainless steel flanges.
- It applies to flanges made of iron or non-alloy steel (not alloyed with other metals).
- The inner diameter is a key classification factor.
