Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the applicable Indian Standard for the relevant use category: Category A (potable water supply), Category B (agriculture and pump suction/delivery lines), or Category C (drainage and sewerage). Verify the CM/L number, product scope, and licensed facility on the BIS online register before placing the purchase order.

2
Confirm the imported PVC pipes and fittings comply with the lead extraction limits specified in column (3) of the notification for the applicable use category. Non-compliant lead content is an independent statutory ground for detention, separate from the ISI mark requirement.

3
Ensure every pipe and fitting bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018. Marking must be on the product itself and not limited to outer packaging.

4
Include mandatory additional qualifiers in the import declaration for Chapter 39 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. These qualifiers are compulsory with effect from 15 October 2023 and their absence triggers bill-of-entry rejection.

If the consignment originates in Bangladesh, verify applicability of the port restrictions introduced under paragraph 19 of the general notes to the import policy. Goods outside the documented carve-outs in paragraphs 2 and 3 of that notification are restricted to specified ports.

A word of counsel

The single most common error on this tariff line is treating the ISI mark obligation as a single uniform requirement, when the controlling notification maps distinct Indian Standards and lead extraction limits to three separate use categories — potable water, agriculture, and drainage/sewerage. A CM/L licence granted for a Category C drainage product does not cover a Category A potable-water pipe; customs and the Bureau of Indian Standards both verify the match between the licensed use category and the declared end-use, and a category mismatch triggers detention regardless of whether the ISI mark is physically present on the product.

Frequently asked

Does HSN 3917 39 20 require BIS certification?

Yes. PVC pipes and fittings of addition polymerisation products falling within Categories A, B, or C of G.S.R. 228(E) must conform to the specified Indian Standard and bear the ISI mark under a CM/L licence issued by the Bureau of Indian Standards under the ISI Mark Scheme, with effect from 15 October 2023.

Are lead extraction limits a separate compliance requirement from the ISI mark?

Yes. The Lead Stabilizer in Polyvinyl Chloride (PVC) Pipes and Fittings Rules, 2021 impose category-specific lead extraction limits in column (3) of the notification; non-compliance with those limits is an independent statutory ground for detention distinct from the ISI mark requirement.

Do the mandatory import declaration qualifiers under CBIC Circular 23/2023-Cus apply to this HSN?

Yes. Chapter 39 commodities, including HSN 3917 39 20, are covered by the mandatory additional qualifiers stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, effective 15 October 2023; absence of these qualifiers triggers bill-of-entry rejection at customs.

Does a single CM/L licence cover PVC pipes and fittings across all three use categories?

No. The CM/L licence is scope-specific by use category, applicable Indian Standard, size range, and manufacturing facility; a licence granted for one category does not authorise import of product classified under a different category, and customs verifies the category match against the BIS register.
