Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against the applicable IS 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 and licensed product scope on the BIS online register before placing the purchase order.

2
Confirm the consignment conforms to the lead extraction limits specified in column (3) of the notification for the relevant use category. Lead-extraction compliance is a statutory condition independent of the ISI mark; absence of documentary evidence triggers detention.

3
Ensure every pipe and fitting bears the ISI mark and the supplier's CM/L number per Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself; marking on packaging alone does not satisfy the statutory requirement.

4
File the bill of entry with mandatory additional qualifiers for goods under Chapter 39 as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. This requirement applies with effect from 15 October 2023 and is verified at assessment independently of BIS QCO documentation.

5
If the consignment originates in Bangladesh, verify whether port restrictions under paragraph 19 of the general notes to the ITC (HS) 2022 import policy apply. Goods outside the documented exemptions in paragraphs 2 and 3 are restricted to specified ports of entry.

A word of counsel

The most common error on this tariff line is treating PVC pipes and fittings as a single undifferentiated category for CM/L licensing purposes. The QCO organises product scope into three distinct use categories — potable water, agriculture, and drainage/sewerage — each mapped to a different Indian Standard with its own lead extraction limit in the notification schedule. A CM/L licence covering Category B (agricultural) pipes does not authorise import of Category A (potable water) pipes; customs has detained consignments where the declared end-use category on the bill of entry does not match the use scope of the supplier's CM/L licence.

Frequently asked

Does HSN 3917 33 00 require BIS certification?

Yes. PVC pipes and fittings under this tariff line must conform to the applicable Indian Standard for the relevant use category and bear the ISI mark under a BIS CM/L licence, with effect from 30 March 2021 under G.S.R. 228(E).

Are there separate Indian Standards for different end uses of PVC pipes?

Yes. The Lead Stabilizer in PVC Pipes and Fittings Rules, 2021 map Category A (potable water), Category B (agriculture and pump lines), and Category C (drainage and sewerage) to distinct Indian Standards listed in the notification schedule; a CM/L licence is use-category-specific.

Is lead extraction limit compliance a separate requirement from the ISI mark?

Yes. Conformity to the lead extraction limits in column (3) of G.S.R. 228(E) is a statutory condition of the QCO; the ISI mark alone does not discharge this obligation, and test documentation demonstrating compliance must accompany the consignment.

Does a single CM/L licence cover all pipe sizes and fittings within one use category?

No. A CM/L licence is scope-specific by product variant, size range, and manufacturing facility; pipes or fittings outside the licensed scope, or produced at an unlicensed plant, are not covered and are liable to detention at port.
