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 (potable water, agriculture, or drainage/sewerage). Verify the supplier's CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.

2
Confirm the use-category of the consignment against the three QCO categories: Category A (potable water supply), Category B (agriculture and suction/delivery lines of agricultural pumps and rainwater systems), or Category C (drainage and sewerage). The applicable Indian Standard and the lead-extraction limits both vary by category.

3
Ensure each pipe and tube bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018, and that the product conforms to the lead-extraction limits specified in column (3) of the notification for the declared use-category. Marking must appear on the product, not packaging alone.

4
Comply with the mandatory additional-qualifier requirement in import declarations for Chapter 39 goods. From 15 October 2023, declarations must include the qualifiers stipulated in paragraphs 4.1 and 4.2 of the relevant CBIC circular at the item level on the bill of entry.

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 carve-outs in paragraphs 2 and 3 of the notification are restricted to specified ports.

A word of counsel

The single most common error on this tariff line is importing PVC pipes without mapping the consignment to the correct QCO use-category before the purchase order. Each of the three categories — potable water, agriculture, and drainage/sewerage — attracts a distinct Indian Standard and a distinct set of lead-extraction limits; a pipe licensed and marked for Category C (drainage) cannot be cleared as Category A (potable water), and customs detention follows when the declared end-use and the CM/L product scope do not align. Confirm the category-specific IS number and lead-extraction compliance in the supplier's CM/L scope before shipment, not at the port of entry.

Frequently asked

Does HSN 3917 23 10 require BIS certification?

Yes. Seamless PVC pipes 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 the Lead Stabilizer in PVC Pipes and Fittings Rules, 2021.

Do additional import-declaration qualifiers apply to this HSN?

Yes. CBIC Circular 23/2023-Cus requires mandatory additional qualifiers in import declarations for Chapter 39 commodities from 15 October 2023; the qualifiers must be entered at the item level per paragraphs 4.1 and 4.2 of that circular.

Does the QCO apply equally to potable water pipes and drainage pipes under this HSN?

The QCO applies to all three use-categories, but the specific Indian Standard and lead-extraction limits differ by category. A CM/L licence is category- and standard-specific; clearance of a pipe under a category not covered by the supplier's licence triggers detention.

Does a single CM/L licence cover all PVC pipe sizes and use-categories from the same manufacturer?

No. The CM/L licence is scope-specific by use-category, Indian Standard, pipe size range, and manufacturing facility; pipes outside the licensed scope or produced at an unlicensed plant are not covered and may not bear the ISI mark.
