BIS certification for farm machinery — what's actually in scope after Scheme X.

Scheme I — ISI Mark is the routine grant path operated under Schedule-I of the BIS (Conformity Assessment) Regulations, 2018, as amended by the BIS (CA) Amendment Regulations, 2020. It is the path used for almost all farm-machinery component certifications — pumps, sprayers, engines, fasteners, lighting. Application, factory inspection, sample testing, and grant follow a documented sequence. Marking fees are governed by Annexure-I of Scheme I and depend on the specific IS standard.

Scheme II — CRS (Compulsory Registration Scheme) applies to electronics and IT goods; rarely the lead scheme on a farm-machinery programme but relevant for in-vehicle electronics modules (e.g. precision-ag controllers).

Scheme X — Machinery and Electrical Equipment Safety was issued by the Ministry of Heavy Industries on 28 August 2024 as the Omnibus Technical Regulation Order, 2024 — originally effective 28 August 2025, deferred by 12 June 2025 amendment to 1 September 2026^[6], then rescinded with immediate effect on 14 January 2026 by MHI^[5]. As of May 2026, Scheme X is not applicable. Anyone reading consultancy content that still presents Scheme X as forthcoming is reading content that has not been updated since the rescission.

Product-specific QCOs (Quality Control Orders) — issued by the relevant Ministry for narrowly defined product categories — continue to apply. The Pumps QCO 2023 is the most directly relevant on agri programmes; centrifugal jet pumps for water-supply or irrigation use are within scope and require ISI marking.

For an Indian manufacturer with a clean dossier and conforming factory, plan 4–6 months from application submission to ISI Mark grant under Scheme I. The split is roughly: 2–3 weeks application processing and inspection scheduling; 2–4 weeks inspection plus sample drawal; 4–8 weeks laboratory testing depending on the IS; 2–4 weeks grant decision and marking-plan finalisation. The total compresses materially when pre-submission audits eliminate the most common dossier defects before BIS sees them.

For foreign manufacturers under FMCS, plan 6–9 months. The additional time covers AIR appointment and notarisation, overseas factory inspection logistics (BIS officers travel to the foreign facility — increasingly with hybrid / remote audit elements), and the bank guarantee mechanics. The FMCS scheme is mature — operated since 2000 — and the steps are well-documented^[3].

Surveillance. Once the licence is granted, BIS conducts annual surveillance — production sample drawal for laboratory verification plus a factory check against the originally approved layout and quality plan^[7]. Surveillance is the operational discipline that protects the licence between renewals; surveillance non-conformance can trigger licence suspension.

Renewal. Licences are granted for a minimum of 1 year and a maximum of 5 years. Renewal applications must be filed at least 3 months before expiry — the ₹5,000 late fee is a soft penalty; the hard penalty is the suspension of marking authority during the gap, which interrupts despatch of marked stock to dealers and can trigger contractual issues with downstream OEMs.

In our practice, three failure modes account for most rejection or delay cycles:

1. Test report / IS revision mismatch. Laboratory reports cite parameters from a superseded IS revision, or test methods that don’t match the IS clause numbers in the application. Triggers a re-test under the current revision — 4–8 week delay per occurrence.
2. Factory layout discrepancy. The factory as inspected differs from the layout submitted — most often raw-material storage, quality-control bench placement, and segregation of marked vs unmarked production. Triggers a re-inspection cycle.
3. FMCS — AIR appointment defects. Foreign manufacturers submit Authorised Indian Representative letters that lack notarisation in the required format, or designate an AIR who cannot demonstrate residency. Each defect adds 3–6 weeks.

Each is preventable with a pre-submission walkthrough that takes 3–5 working days. We run this on every BIS engagement before a single document goes to BIS Manak Online.

BIS in isolation is a paperwork problem. BIS as one thread of a farm-machinery regulatory pack — sequenced against CMVR/AIS at ARAI / ICAT / FMTTI Budni, against TREM-IV emission compliance for the engine, against the dealer-network rollout calendar — is a planning problem. AgPro runs it as the latter. Engagements begin with a regulatory map: every approval the product needs, sequenced with time-on-clock, with parallel tracks identified and resourced from week one.

The team is engineer-led, with hands-on history at ARAI, ICAT, and FMTTI Budni and direct experience filing under FMCS for overseas tractor and implement OEMs. The Pune office is 15 km from ARAI and a short drive from the test sites; the New Delhi office puts us within walking distance of the regulatory ministries. For multi-product portfolios we bundle BIS Scheme I work with CMVR/AIS at the whole-vehicle layer and CIBRC for any chemistry-driven sub-systems (e.g. coatings, packaging regulated under separate Acts).
