HS-6 · Subheading
730519
Iron or steel (excluding cast iron); line pipe of a kind used for oil or gas pipelines (not seamless), (not longitudinally welded), having circular cross-sections, external diameter exceeds 406.4mm
Heading 7305 — Iron or steel (excluding cast iron); tubes and pipes (e.g. welded, riveted or similarly closed), having circular cross-sections, external diameter of which exceeds 406.4mm, not seamless
Chapter 73: Articles of iron or steel
Plain-language overview
Use HS-6 730519 when importing or exporting large iron or steel line pipes designed for oil or gas pipelines. These pipes have a circular cross-section and an external diameter exceeding 406.4mm. For example, a shipment of welded steel pipes for a gas pipeline would fall under this code.
This code specifically applies to line pipes that are not seamless and are not longitudinally welded. In contrast, HS-6 730520 covers similar pipes that are seamless, which are often used in high-pressure applications. Understanding these distinctions is crucial for accurate classification.
The 730519 subheading narrows down the broader category of iron or steel products to those specifically used in pipeline applications. This includes pipes that are critical for transporting oil and gas, making them essential for energy infrastructure.
When classifying your products, keep in mind that the external diameter is a key factor. If your pipes are seamless or have a diameter of 406.4mm or less, you may need to look at different HS codes, such as 730520 or 7304.
