HSN Code and GST Rate of PVC Pipes in India

Confused about product classification? The HSN Code Finder helps you pinpoint the correct code with ease.

The HSN Code (Harmonised System of Nomenclature) for PVC pipes falls under the heading 3917. This category is specifically for "Tubes, pipes, and hoses, and fittings thereof (for example, joints, elbows, flanges), of plastics."

PVC (Polyvinyl Chloride) pipes are widely used in construction, plumbing, agriculture, and irrigation systems. The most commonly applicable HSN code for PVC pipes is:

• HSN Code: 3917
• GST Rate: 18%

The HSN code for plastic pipes and fittings is structured hierarchically. While the primary heading is 3917, more specific 6-digit and 8-digit codes apply depending on the polymer type and the product's functional nature.

Below is a detailed breakdown for PVC pipes and related products as per the 2026 GST guidelines:

HSN code classification for plastic pipes and fittings

Key takeaway: For standard rigid PVC pipes used in Indian construction and agriculture, the most applicable HSN code is 3917 23 90. For associated fittings like elbows and couplers, you must use 3917 40 00.

Beyond the pipes themselves, businesses in the Indian market frequently deal with associated products that fall under the same HSN chapter but require distinct codes. Here is a concise guide to these classifications for 2026:

• PVC pipe fittings (Joints, Elbows, Tees, Couplers, End caps): These components are classified under a dedicated sub-heading. Irrespective of the specific plastic type (such as PVC, UPVC, or CPVC), plastic fittings generally fall under HSN code 3917 40 00. The applicable GST rate remains 18%.
• PVC hoses (Flexible): If your business deals with flexible PVC hoses (e.g., for gardening or low-pressure irrigation), these fall under the broader "flexible tubes" categories. For non-reinforced hoses supplied without fittings, use 3917 32. For hoses with fittings already attached, use 3917 33 00. High-pressure hoses (with a minimum burst pressure of 27.6 MPa) require 3917 31 00.
• PVC conduit pipes (Electrical): Rigid PVC pipes used as electrical conduits are still classified as rigid tubes made of vinyl chloride polymers. The standard code 3917 23 (specifically 3917 23 90) is applicable. There is no separate HSN category specifically for electrical conduits.

Important note: While a product may have a specific industrial application (such as electrical casing or heavy-duty drainage), the GST classification is strictly based on its material composition and physical form (i.e., a rigid tube of PVC). Consequently, 3917 23 remains the correct designation for standard rigid PVC conduit pipes.

Identifying the right HSN code for PVC pipes is crucial for tax accuracy and compliance. Here's how you can determine it:

• Refer to GST/HSN code directories: Use government portals or reliable HSN code lookup tools.
• Consult tax experts: Professionals can offer guidance on classification based on usage and material.
• Analyse product composition: Ensure your pipe is made of plastic (PVC) and intended for transport of fluids, which places it under heading 3917.
• Check industry standards: Certain product types may have specific sub-classifications under the same HSN heading.
• Use invoicing software: Most billing software auto-suggests correct HSN codes based on item description.

Correct classification ensures smooth GST compliance and reduces chances of audits or fines.

Conclusion

Using the correct HSN code for PVC pipes (3917) is essential for tax accuracy, legal compliance, and streamlined trade within the Indian market. Whether you are a manufacturer, distributor, or exporter, staying updated with HSN classifications simplifies your GST filing and significantly reduces the risk of penalties during audits.
