HSN code 7306, under the chapter 'Articles of Iron or Steel', encompasses a wide array of 'Other tubes, pipes, and hollow profiles' manufactured using methods like open seam, welding, riveting, or similar closure techniques. This heading is crucial for procurement teams dealing with structural components, infrastructure projects, and specialized engineering applications across India. Unlike seamless pipes (7304) or large diameter pipes (7305), 7306 covers a vast range of commonly used welded and closed hollow sections. Understanding this HSN is vital for accurate customs classification, GST compliance, and sourcing the right materials for diverse industrial needs, from construction to oil and gas infrastructure. MetaleMart’s extensive catalog features numerous products falling under HSN 7306, catering to the varied demands of Indian businesses.
What HSN 7306 Covers
HSN 7306 is a comprehensive heading for "Other tubes, pipes and hollow profiles (for example, open seam or welded, riveted or similarly closed), of iron or steel." This broad classification primarily includes products manufactured using methods that result in a seam, unlike seamless pipes (classified under HSN 7304). It encompasses a vast range of commonly used steel pipes and tubes, including Electric Resistance Welded (ERW), Electric Fusion Welded (EFW), and spiral welded pipes. The heading specifically mentions 'open seam or welded, riveted or similarly closed' constructions, making it the default category for most manufactured hollow steel sections. Sub-headings further differentiate based on intended use, such as 'line pipe' (730610), 'casing and tubing' for oil and gas wells (730620), and other welded hollow profiles, including those of non-circular cross-section. Also covered are galvanized pipes within the line pipe sub-category. Typically, products under HSN 7306 are utilized in construction, infrastructure development, oil and gas transportation and extraction, agricultural applications, and general engineering fabrication. It's important to note exclusions: Seamless pipes fall under 7304, cast iron pipes under 7303, and pipes with an outer diameter exceeding 406.4 mm are classified under 7305. Accurate classification depends on the manufacturing process and specific application.Common Materials & Grades

Frequently Asked Questions about HSN 7306
What's the difference between HSN 7306, 7303, 7304, and 7305?
The primary difference lies in their construction and application. HSN 7306 covers 'other' tubes, pipes, and hollow profiles, including welded or riveted types not specifically classified elsewhere, often used for general industrial purposes, line pipes, and casing. HSN 7303 covers cast iron pipes, while 7304 covers seamless tubes and pipes, which are made without a welded seam and are typically used for high-pressure applications. HSN 7305 covers pipes and tubes of iron or steel with outer diameters exceeding 406.4 mm, used for specific large-scale projects. Always verify the specific product details against the official HSN classification chapter notes.
What specific types of pipes and tubes are classified under HSN 7306?
HSN 7306 specifically covers 'other' tubes, pipes, and hollow profiles of iron or steel that are manufactured by methods such as open seam, welding, riveting, or similar closure techniques. This broad category importantly excludes seamless pipes (HSN 7304), cast iron pipes (HSN 7303), and large diameter pipes covered under 7305. Procurement teams should ensure their welded or specially closed hollow profiles for construction, oil & gas, and general engineering fit within this HSN code. MetaleMart offers a wide array of welded MS and SS pipes and tubes that fall under this classification.
What are some common examples of products and materials covered under HSN 7306?
Under HSN 7306, you'll find various pipes and tubes like welded MS (Mild Steel) pipes, ERW (Electric Resistance Welded) pipes, EFW (Electric Fusion Welded) pipes, steel hollow sections (both circular and non-circular), line pipes for oil and gas, and casing/tubing for drilling operations. MetaleMart's catalog includes popular grades like ASTM A53/A106 for structural and line pipes, and various hollow sections in mild steel and stainless steel suitable for diverse industrial applications classified under this HSN.
How does HSN 7306 apply to oil and gas pipelines and drilling?
HSN 7306 covers a broad range of welded and similarly closed tubes and pipes. For oil and gas applications, specific sub-codes like 730610 (Line Pipe) and 730620 (Casing and Tubing) are relevant. Welded tubes for general engineering purposes fall under the broader 7306 heading, often distinguished by their non-circular cross-sections (730660) or specific material compositions. Buyers should consult their CHA or tax advisor for precise classification, but MetaleMart lists many products like MS Square & Rectangular Hollow Sections suitable for this code. Iranian buyers often look for these under specific trade names for structural use.
