BIS QCO APPLICABLE · ISI MARK SCHEME · IS 814

HSN 8311 30 90 (coated rods and cored wire of base metal for soldering, brazing or welding by flame) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 814:2004 and IS 6419:1996 is mandatory under the ISI Mark Scheme with effect from 18 January 2024 under the Welding Rods and Electrodes (Quality Control) Order, 2023. No separate customs-clearance overlay applies to this tariff line.

Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 814:2004 (covered electrodes for manual metal arc welding of carbon and carbon-manganese steel) or IS 6419:1996 (welding rods and bare electrodes for gas shielded arc welding of structural steel), as applicable to the product. Verify the CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.
Welding Rods and Electrodes (Quality Control) Order, 2023 · S.O. 3153(E) dated 14-07-2023 · S.O. 777(E) dated 12-02-2026
2
Ensure every rod or cored wire bears the ISI mark and the supplier's CM/L number in accordance with Scheme-I of Schedule-II of the Bureau of Indian Standards (Conformity Assessment) Regulations, 2018. Marking must appear on the product or its individual packaging unit, not on the outer carton alone.

3
Confirm the phased enforcement dates with the supplier: the general effective date is 18 January 2024; for small enterprises (as defined under the MSMED Act, 2006) it is 18 April 2024; for micro enterprises it is 18 July 2024. Product manufactured after the applicable enterprise-category date must be ISI-marked.

4
If the supplier claims the Udyam-portal micro-enterprise exemption, obtain a Chartered Accountant certificate confirming investment in plant and machinery not exceeding ₹1 crore and annual turnover not exceeding ₹5 crore for the previous financial year. The exemption does not survive a mismatch against Udyam Portal registration.
Welding Rods and Electrodes (Quality Control) Order, 2023 · S.O. 3153(E) dated 14-07-2023 · MSMED Act, 2006 (27 of 2006)
5
Quote the supplier's BIS CM/L number on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or product-scope-mismatched licence triggers consignment detention at port.

A word of counsel

The single most common error on this tariff line is importing flux-cored solder wire or flux-cored tubular electrodes under HSN 8311 30 90 without recognising that each product sub-type carries its own Quality Control Order: IS 1921:2005 governs flux cored solder wire under the Flux Cored Solder Wire (Quality Control) Order, 2023 (S.O. 4092(E)), and IS 15769:2008 governs flux cored tubular electrodes under S.O. 1203(E). Importing any of these under a CM/L licensed only against IS 814:2004 or IS 6419:1996 results in a scope mismatch — the consignment is treated as uncertified, triggering detention regardless of whether the supplier holds a BIS licence for a different product in the same tariff line.

Frequently asked

Does HSN 8311 30 90 require BIS certification?

Yes. Coated rods and cored wire under this tariff line must conform to IS 814:2004 or IS 6419:1996, as applicable, under the ISI Mark Scheme. Imports are permitted only from manufacturers holding a current BIS CM/L licence, with effect from 18 January 2024.

Does the Udyam micro-enterprise exemption eliminate the BIS QCO obligation entirely?

No. The exemption under the Welding Rods and Electrodes (Quality Control) Order, 2023 applies only to goods manufactured by an enterprise whose investment in plant and machinery does not exceed ₹1 crore and whose annual turnover does not exceed ₹5 crore, as certified by a Chartered Accountant. The BIS obligation applies in full to all other enterprises.

Is a separate CM/L licence required for IS 814:2004 and IS 6419:1996?

Yes. Each IS standard requires a distinct CM/L licence; a licence against IS 814:2004 does not authorise supply of products within the IS 6419:1996 scope, and customs detains consignments where the CM/L scope does not match the product on the bill of entry.

Do flux cored solder wire and flux cored tubular electrodes share the same QCO as welding rods and electrodes under IS 814 and IS 6419?

No. Flux cored solder wire is governed by IS 1921:2005 under S.O. 4092(E), and flux cored tubular electrodes by IS 15769:2008 under S.O. 1203(E); each is a separate Quality Control Order with its own CM/L licensing requirement.
