Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence under the ISI Mark Scheme per Scheme-I of Schedule II of the BIS (Conformity Assessment) Regulations, 2018. Verify the supplier's CM/L number, licensed product scope (use category and size range), and manufacturing facility on the BIS online register before placing the purchase order.

2
Confirm that the consignment's intended end-use category is covered by the licensed scope: Category A (potable water supply), Category B (agriculture, suction and delivery lines of agricultural pumps, rainwater systems), or Category C (drainage and sewerage). A CM/L licence is category-specific; a licence for Category C does not cover Category A supply.

3
Ensure each tube bears the ISI mark and the supplier's CM/L number per Scheme-I of Schedule II to the BIS (Conformity Assessment) Regulations, 2018. Confirm that the product also meets the lead extraction limits specified in column (3) of the notification; lead-extraction conformity is a separate mandatory condition alongside the standard mark.

4
Comply with Central Board of Indirect Taxes and Customs Circular 23/2023-CUS dated 30-09-2023 by including mandatory additional qualifiers in the import declaration for goods under Chapter 39. These qualifiers are mandatory with effect from 15-10-2023 and must be declared at the time of filing the bill of entry.

5
Quote the supplier's BIS CM/L number on the bill of entry, supported by use-category documentation and lead-extraction conformity evidence. If the consignment originates in Bangladesh, verify applicability of port restrictions introduced under paragraph 19 of the ITC (HS) 2022 general notes; exempted goods are listed in paragraphs 2 and 3.

A word of counsel

The most frequent error on this tariff line is treating the BIS CM/L licence as a single, product-wide authorisation when in fact the Lead Stabilizer in PVC Pipes and Fittings Rules, 2021 structure the obligation across three distinct end-use categories — potable water, agriculture, and drainage — each mapped to separate Indian Standards and separate lead extraction limits. An importer who clears a consignment under a Category C (drainage) CM/L for what is actually Category A (potable water) product faces detention and re-export, not merely re-labelling, because the underlying certified standard is different and the lead-extraction tolerance differs materially.

Frequently asked

Does HSN 3917 29 10 require BIS certification?

Yes. Seamless tubes of vinyl acetate and vinyl chloride copolymers classified here must conform to the Indian Standard applicable to their end-use category and bear the ISI mark under a BIS CM/L licence, mandatory with effect from 30 March 2021 under the Lead Stabilizer in PVC Pipes and Fittings Rules, 2021.

What end-use categories govern which Indian Standard applies?

The Lead Stabilizer in PVC Pipes and Fittings Rules, 2021 (G.S.R. 228(E)) specify three categories: Category A for potable water supply, Category B for agriculture and agricultural pump lines, and Category C for drainage and sewerage. The applicable Indian Standard and lead extraction limit differ by category.

Are mandatory additional qualifiers required in the import declaration for this HSN?

Yes. CBIC Circular 23/2023-CUS dated 30-09-2023 requires mandatory additional qualifiers in import declarations for goods under Chapter 39, including this tariff item, with effect from 15 October 2023.

Does one CM/L licence cover tubes intended for both potable water and drainage applications?

No. The CM/L is scope-specific by end-use category; a licence issued under one category does not authorise supply under another, and customs detains consignments where the declared end-use does not match the licensed category on the BIS register.
