BIS ISI Certification for Cross Recessed Screws in India: Standards, Process & Requirements

Drilling screws, tapping screws, drywall screws, chipboard screws and wood screws are all covered by the Cross Recessed Screws (Quality Control) Order, one of the newest and most actively amended QCOs, spanning 14 notified IS standards.

Fasteners rarely draw attention until one fails, which is exactly why BIS brought cross recessed screws under compulsory certification through the Cross Recessed Screws (Quality Control) Order, 2024 (S.O. 4099(E), dated 20 September 2024) — one of the newest QCOs on the books, already revised twice since. The category spans drilling screws, tapping screws, and the wood, drywall and chipboard screws used throughout construction and furniture manufacturing, across 14 notified IS standards.

For hardware manufacturers and importers, this is a relatively recent compliance obligation that many in the supply chain are still adapting to. This guide lists all 14 IS standards, explains what BIS certification verifies for fasteners, and walks through the licensing process, documentation, timeline and common pitfalls.

🎯 What Is BIS ISI (Scheme-I) Certification?

BIS Scheme-I is the classical Indian Standards Institution (ISI) mark scheme — India's original and most rigorous product certification route. Unlike the self-declaration model used under CRS for electronics, Scheme-I certification requires the manufacturer to hold a BIS licence granted only after laboratory testing and a physical BIS audit of the factory's manufacturing process and quality control system. The ISI mark on a product is a direct assurance that both the product and the process producing it meet the notified Indian Standard.

📌 Three regulatory updates in under two years: the 2024 Order, the 2025 Order, and the 2026 Amendment Order together show how actively BIS is refining this category — manufacturers already certified should check whether the 2026 amendment affects their existing licence.

📄 The Governing Quality Control Order

This category is notified under the Cross Recessed Screws (Quality Control) Order, 2024 (S.O. 4099(E), dated 20 September 2024). Followed by the Cross Recessed Screws (Quality Control) Order, 2025 (S.O. 3927(E), dated 27 August 2025) and the Cross Recessed Screws (Quality Control) Amendment Order, 2026 (S.O. 3298(E), dated 22 June 2026).

🔧 What BIS ISI Certification Verifies

BIS testing for cross recessed screws evaluates dimensional accuracy (head geometry, thread pitch, recess conformance), mechanical property class (tensile and torsional strength appropriate to the steel grade or stainless/non-ferrous material specified), coating and corrosion resistance where applicable, and drilling or tapping performance for self-drilling and self-tapping variants. Because many of these standards are directly aligned to ISO specifications, testing typically follows internationally recognised methods adapted for Indian certification.

Very recent, still evolving: the Cross Recessed Screws (Quality Control) Order, 2024 was followed by a 2025 Order (S.O. 3927(E), 27 August 2025) and a 2026 Amendment Order (S.O. 3298(E), 22 June 2026). Confirm the current in-force requirements with BIS before testing — this is one of the fastest-changing QCOs currently in effect.

📋 Step-by-Step: BIS ISI (Scheme-I) Licensing Process

Scheme-I is a test-and-audit certification, more rigorous than the self-declaration route used for CRS-scheme electronics. The sequence is:

  1. Identify the applicable IS standard(s)Confirm which of the notified Indian Standards under this QCO apply to your exact product variant and specification.
  2. Test at a BIS-recognised laboratorySubmit representative samples for testing against the applicable IS standard. The test report is the foundation of the ISI licence application.
  3. Prepare documentationCompile factory details, quality control records, product technical data, and — for foreign manufacturers — the Authorised Indian Representative (AIR) nomination under FMCS.
  4. File the online applicationSubmit the application on the BIS Manak Online portal with the test report, factory details, and supporting documents.
  5. Factory auditUnlike the CRS self-declaration route, Scheme-I (ISI) certification involves a physical BIS assessment of the manufacturing unit and its quality control system.
  6. Grant of licence and ISI markBIS reviews the application and audit findings and grants the licence with a unique licence number, allowing use of the ISI mark on the product.
  7. Surveillance, renewal and market samplingLicensees remain under periodic BIS surveillance, including market sample testing, and must renew the licence on schedule.

📂 Documents Required

A complete file at the outset shortens both the review and audit stages. You will typically need:

14IS Standards in Scope
FactoryAudit Required
PeriodicSurveillance & Renewal

Because Scheme-I combines laboratory testing with a factory audit, timelines run longer than the self-declaration CRS route. Once granted, the BIS ISI licence remains subject to ongoing surveillance, including unannounced market sampling, and must be renewed on schedule to stay valid.

Common Mistakes That Delay ISI Licensing

Frequently Asked Questions

Is BIS ISI certification mandatory for cross recessed screws?

Yes. All 14 notified IS standards under the Cross Recessed Screws QCO are mandatory — a covered screw type cannot be manufactured, imported or sold in India without the corresponding BIS ISI licence.

How new is this certification requirement?

Very. The original Order was issued in September 2024, followed by a further Order in 2025 and an Amendment Order in June 2026 — this is one of the most recently notified and actively revised QCOs currently in force.

Do drywall and chipboard screws need separate certification from general tapping screws?

Yes. IS 18507 (drywall screws), IS 18508 (chipboard screws) and IS 18509 (wood screws) are each distinct standards from the general cross recessed tapping and drilling screw standards, and each needs its own BIS ISI licence.

Are these standards aligned to international ISO specifications?

Many are. Standards like IS 18471 (Parts 1-3) and IS 18480 (Parts 1-3) directly reference their corresponding ISO 15481-15483 and ISO 7049-7051 specifications.

How long does certification take for screws?

Testing for fasteners is generally faster than for pressure equipment or cement, but factory audit scheduling still applies; a realistic timeline is typically a couple of months.

What happens if a hardware importer sells uncertified screws?

It is a violation of the Cross Recessed Screws QCO, exposing the importer or seller to enforcement action including stock seizure and penalties.
