HS Code for Stainless steel line pipe

The classification of stainless steel line pipe under HS code 7304.11 is governed by the General Rules of Interpretation (GRI), specifically GRI 1 and 6. This code is designated for seamless tubes and pipes made of stainless steel that are specifically engineered for use in oil and gas pipelines. To qualify for this classification, the product must meet the definition of stainless steel provided in Chapter 72, Note 1(e), which requires a chromium content of at least 10.5% and a carbon content of no more than 1.2%. The term 'seamless' refers to the manufacturing process where the pipe is formed from a solid billet through piercing or extrusion, ensuring there is no welded seam. This structural integrity is vital for the high-pressure environments typical of energy transport. Furthermore, the 'line pipe' designation implies adherence to specific industrial standards, such as API 5L, which differentiate these products from general-purpose mechanical or structural tubing. The classification ensures that high-performance materials used in critical infrastructure are tracked accurately for trade and safety regulations.

Products Included

• Seamless stainless steel oil transport pipes
• High-pressure gas line pipes
• Corrosion-resistant seamless pipelines for offshore drilling
• ASTM A312 compliant seamless line pipes
• Duplex stainless steel seamless line pipe

Common Misclassification

This product is frequently confused with HS code 7306.11. The primary difference lies in the manufacturing method; 7306.11 covers welded line pipe, whereas 7304.11 is strictly for seamless products. Additionally, it may be misclassified under 7304.41, which covers other seamless stainless steel tubes. However, 7304.11 takes precedence if the pipe is specifically designed for oil and gas line applications rather than general fluid transport or structural use.

FAQ

What is the HS code for Stainless steel line pipe?

The primary HS code for seamless stainless steel line pipe used for oil or gas pipelines is 7304.11.

Does this code include pipes used for water transport?

No, pipes intended for water transport or general plumbing are typically classified under 7304.41 or 7304.49, as 7304.11 is reserved for oil and gas infrastructure.
