Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer whose licence covers the specific PVC pipe or fitting 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, category scope, and licensed facility on the BIS online register before placing the purchase order.

2
Confirm the consignment meets the lead extraction limits specified in column (3) of the notification for the relevant category. The CM/L licence alone does not substitute for documented lead-extraction compliance; retain the test evidence in the import record.

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

Include all 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. This requirement is in force with effect from 15 October 2023 and a declaration missing required qualifiers will be held at customs.

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 are restricted to specified ports of entry.

A word of counsel

The single most common error on this tariff line is treating the CM/L licence as a single undifferentiated authorisation, when the QCO notification distinguishes three discrete use-categories — potable water, agriculture, and drainage — each mapped to a separate Indian Standard and a separate lead extraction limit. A CM/L covering Category C (drainage) does not authorise import of Category A (potable water) pipes; customs and BIS both verify category-specific scope at the point of clearance, and a scope mismatch triggers detention regardless of whether the product physically bears the ISI mark.

Frequently asked

Does HSN 3917 32 20 require BIS certification?

Yes. PVC pipes and fittings under this tariff line must conform to the Indian Standard applicable to their use category and bear the ISI mark under a CM/L licence issued under the ISI Mark Scheme, with effect from 15 October 2023.

Are the lead extraction limits a separate requirement from the BIS CM/L licence?

Yes. G.S.R. 228(E) under the Lead Stabilizer in Polyvinyl Chloride (PVC) Pipes and Fittings Rules, 2021 imposes independent lead extraction limits by use category; compliance with both the IS standard and the lead limits is required for each consignment.

Does one CM/L licence cover all three use categories — potable water, agriculture, and drainage?

No. The CM/L licence is category-specific; a licence granted for Category C (drainage and sewerage) does not cover Category A (potable water supply) or Category B (agriculture), and import under an out-of-scope category triggers detention and potential confiscation.

What are the mandatory additional qualifiers required in the import declaration for Chapter 39?

CBIC Circular 23/2023-Cus dated 30-09-2023 prescribes specific additional qualifiers for import declarations covering Chapter 39 commodities; the exact fields are set out in paragraphs 4.1 and 4.2 of that circular and must be completed on every bill of entry from 15 October 2023.
