Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 17729:2021 for agro-textile water storage tanks. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure each container bears the ISI standard 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 and not on packaging alone.

3
If the containers are liquid-capacity measures exceeding 20 litres, verify Legal Metrology registration and product approval certificates. Sections 19, 20, and 22 of the Legal Metrology Act, 2009 and Rules 11 to 15 of the Sixth Schedule of the Legal Metrology (General) Rules, 2011 govern this requirement.

A word of counsel

The single most common error on this tariff line is assuming that the BIS QCO applies to all large plastic tanks when the IS 17729:2021 scope under the Agro Textile (Quality Control) Order, 2023 is specific to agro-textile water storage applications. Importers sourcing industrial or construction-use plastic tanks of comparable capacity frequently present a CM/L licence whose licensed product scope does not cover the agro-textile application — and customs detention follows on a scope mismatch at port, even where the licence number is otherwise valid and current.

Frequently asked

Does HSN 3925 10 00 require BIS certification?

Yes. Conformity to IS 17729:2021 is mandatory under the ISI Mark Scheme with effect from 01 April 2024 by virtue of the Agro Textile (Quality Control) Order, 2023; import is permitted only from manufacturers holding a current BIS CM/L licence covering the relevant product scope.

Are additional import-declaration qualifiers required for this HSN?

Yes. CBIC Circular 23/2023-Cus dated 30-09-2023 requires mandatory additional qualifiers in import declarations for Chapter 39 commodities; the qualifiers specified in paragraphs 4.1 and 4.2 of that circular apply with effect from 15 October 2023.

Does the BIS QCO apply to all plastic tanks exceeding 300 litres, regardless of end use?

No. The QCO notification S.O. 4248(E) anchors IS 17729:2021 to agro-textile water storage tanks. Industrial or construction-use plastic tanks of the same capacity may fall outside the BIS QCO scope, but the correct classification of end-use remains the importer's burden to establish at customs.

Does a single CM/L licence cover all tank sizes and manufacturing facilities?

No. A CM/L licence is scope-specific by capacity range, product specification, and licensed manufacturing facility; tanks outside the licensed scope or produced at an unlicensed plant are not covered, and a mismatch against the BIS register triggers detention.
