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 nylon fish net twine — principally IS 1084 or IS 8674 depending on construction. Verify the supplier's CM/L number, licensed product scope, and licensed manufacturing facility on the BIS online register before placing the purchase order.

2
Confirm which IS standard governs the specific construction being imported: IS 1084:2005 for manila and general twines, IS 8674:2013 for polyethylene strand ropes, IS 4572:2022 for polyamide strand ropes, IS 17609:2021 for polyester/polyolefin dual-fibre ropes. The CM/L must be valid against the construction-specific standard, not merely the heading.
S.O. 4327(E) dated 03-10-2024 · applicable IS standards cited in the Ropes and Cordages Quality Control Order, 2024
3
Ensure every unit of twine bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018. Marking must be on the product or its label, not on outer packaging alone.

4
Accompany the consignment with a Pre-Shipment Inspection Certificate from an accredited laboratory in the exporting country certifying absence of prohibited hazardous azo dyes. Imports from EU, Serbia, Poland, Denmark, Australia, Canada, Japan, South Korea, and United Kingdom are exempt from azo dye testing.

5
Quote the supplier's BIS CM/L number and the IS standard reference on the bill of entry alongside the PSIC. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or construction-scope-mismatched licence triggers consignment detention.

A word of counsel

The most common error on this tariff line is treating the Ropes and Cordages QCO as requiring a single generic CM/L — when in fact the Order maps each construction type to a distinct IS standard. A supplier licensed under IS 1084 for general twines is not automatically licensed for polyamide strand ropes under IS 4572 or polyethylene ropes under IS 8674; importing nylon fish net twine against a CM/L scoped only to a different rope family triggers detention on a scope mismatch even where the ISI mark is physically present on the goods.

Frequently asked

Does HSN 5607 50 10 require BIS certification?

Yes. Nylon fish net twine must conform to the applicable Indian Standard and bear the ISI mark under a BIS CM/L licence, with effect from 01 April 2025, pursuant to the Ropes and Cordages Quality Control Order, 2024 notified under S.O. 4327(E).

Is a Pre-Shipment Inspection Certificate required for this tariff line?

Yes, as a textile import policy overlay. A PSIC from an accredited laboratory in the exporting country is required to certify absence of prohibited azo dyes, except for imports from the EU, Serbia, Poland, Denmark, Australia, Canada, Japan, South Korea, and the United Kingdom per DGFT Public Notice 14/2023.

Which IS standard applies to nylon fish net twine specifically?

The Ropes and Cordages QCO 2024 maps multiple IS standards to construction type: IS 1084:2005 covers general twines including fish-net twine; IS 4572:2022 governs polyamide strand ropes; IS 8674:2013 covers polyethylene strand ropes. The CM/L must be scoped to the exact construction and fibre type of the consignment.

Does a single CM/L licence cover all rope and twine constructions from the same manufacturer?

No. Each CM/L is construction-specific and IS-specific; a licence scoped to one standard and rope family does not cover products governed by a different IS standard under the Ropes and Cordages Quality Control Order, 2024.
