Welding consumables, flux-cored electrodes, solder wire and welding cables

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 9857

HSN 8311 90 00 (welding consumables residual) is covered by multiple Bureau of Indian Standards Quality Control Orders spanning flux-cored electrodes, welding cables, flux-cored solder wire, and welding rods and bare electrodes. Conformity to the applicable Indian Standards is mandatory under the ISI Mark Scheme, with enforcement dates ranging from 1 September 2021 to 18 January 2024 depending on product sub-type. No separate customs-clearance overlay applies to this tariff line beyond the BIS obligation.

Compliance steps

1
Identify the precise product sub-type in the consignment before sourcing: flux-cored (tubular) electrodes for gas-shielded or self-shielded metal arc welding of carbon or carbon-manganese steel (IS 15769:2008); welding cables (IS 9857:1990); flux-cored solder wire (IS 1921:2005); or covered electrodes and bare welding rods (IS 814:2004 and IS 6419:1996). Each sub-type falls under a separate Quality Control Order.
Flux Cored (Tubular) Electrodes (Quality Control) Order, 2021 · S.O. 1203(E) dated 12-03-2021; Cables (Quality Control) Order, 2020 · S.O. 294(E) dated 21-01-2020; Flux Cored Solder Wire (Quality Control) Order, 2023 · S.O. 4092(E) dated 18-09-2023; 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
Verify the foreign supplier's BIS CM/L licence number on the BIS online register against the specific Indian Standard covering the consignment's product sub-type. Confirm the licensed product scope, manufacturing facility address, and current validity before placing the purchase order.

3
Ensure every product unit bears the ISI mark and the supplier's CM/L number. Per the applicable QCOs, goods shall conform to the corresponding Indian Standard and bear the Standard Mark under licence from the Bureau of Indian Standards as per Scheme-I of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018.

4
Assess the Micro and Small Enterprise exemption before each shipment for flux-cored solder wire and welding rods. For flux-cored solder wire, Micro Enterprises as defined in the MSMED Act, 2006 registered on the Udyam Portal with investment in plant and machinery not exceeding ₹1 crore and turnover not exceeding ₹5 crore for the previous financial year (certified by a Chartered Accountant) are exempt.
Flux Cored Solder Wire (Quality Control) Order, 2023 · S.O. 4092(E) dated 18-09-2023; 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 licence number and the applicable IS standard on the bill of entry. Customs verifies the CM/L against the BIS register in real time; an absent, expired, or product-scope-mismatched CM/L triggers consignment detention, demurrage, and potential re-export or confiscation.

A word of counsel

The single most common error on this tariff line is filing a single bill of entry for a mixed consignment of welding consumables without identifying each product sub-type against its specific Quality Control Order and Indian Standard. Each sub-type — flux-cored electrodes under IS 15769:2008, welding cables under IS 9857:1990, flux-cored solder wire under IS 1921:2005, and covered or bare electrodes under IS 814:2004 or IS 6419:1996 — requires a separate CM/L licence; a single CM/L covering one product sub-type does not cover the others, and customs detains the entire consignment when any line item lacks a matching CM/L.

Frequently asked

Does HSN 8311 90 00 require BIS certification?

Yes. Multiple Quality Control Orders mandate ISI Mark Scheme certification under CM/L licences tied to specific Indian Standards — IS 15769:2008, IS 9857:1990, IS 1921:2005, IS 814:2004, and IS 6419:1996 — depending on the welding consumable sub-type being imported.

Are Micro or Small Enterprises exempt from any of the QCO obligations on this tariff line?

Yes, for flux-cored solder wire and welding rods. Enterprises registered on the Udyam Portal with investment in plant and machinery not exceeding ₹1 crore and turnover not exceeding ₹5 crore for the previous financial year (certified by a Chartered Accountant) are exempt under the respective QCOs, per the MSMED Act, 2006.

Do different product sub-types within HSN 8311 90 00 have different enforcement dates?

Yes. Flux-cored tubular electrodes under IS 15769:2008 and welding cables under IS 9857:1990 have been covered since 1 September 2021 and 21 January 2020 respectively; flux-cored solder wire under IS 1921:2005 from 19 March 2024; and covered electrodes and bare welding rods under IS 814:2004 and IS 6419:1996 from 18 January 2024.

Does a single CM/L licence cover all welding consumable variants under HSN 8311 90 00?

No. Each CM/L is issued against a specific Indian Standard and product scope; a licence for flux-cored electrodes under IS 15769:2008 does not cover welding cables under IS 9857:1990 or flux-cored solder wire under IS 1921:2005.
