Manufacturing & metal tenders in India: vendor approval and Make in India rules

Short answer: Government manufacturing and metal-fabrication work is bought mainly by Indian Railways (through RDSO-approved vendors), Defence (Ordnance factories, Defence PSUs, DRDO), other PSUs, and state industries corporations, usually as a supply contract against a technical specification rather than a works contract. Many categories require the manufacturer to hold prior vendor or source approval before a bid is even opened. Your bid is also classed Class-I or Class-II local supplier under the Make in India purchase-preference order, which affects who wins when prices are close. GST, EMD and PBG follow the same general structure as any tender, with specific exemptions for Udyam-registered MSEs. Treat this guide as a map; the tender's own eligibility clause and the current government orders are the final word.

Who buys manufactured and metal goods in India?

• Indian Railways — wagons, coaches, track fittings, signalling and electrical equipment, structural steel for bridges and sheds, mostly procured through IREPS with technical specifications set by RDSO.
• Defence — Ordnance factories, Defence PSUs (such as BEML, BEL, HAL) and DRDO buy components, assemblies and fabricated structures, often with security clearance and quality-assurance requirements layered on top of the commercial bid.
• Other PSUs — steel plants, power utilities, oil and gas companies buy spares, fabricated structures and industrial equipment for their own operations and projects.
• State industries corporations and municipal bodies — street furniture, water-supply fittings, metal gates and smaller fabricated items, usually on the state e-procurement portal or GeM.

GeM is a realistic entry point for standard, catalogue-style products in this vertical even before you have department-specific vendor approval; our GeM bidding guide covers registration and catalogue listing.

Vendor or source approval: the gate most tenders don't spell out in one place

Unlike a works contract, a manufacturing or metal-component tender often has a second, earlier gate: approval of the manufacturer itself, separate from approval of the bid.

• Railways (RDSO): for safety and quality-sensitive items, a manufacturer applies for vendor registration (through the Unified Vendor Approval Module on IREPS), which typically involves a works capability assessment, sample or type testing, and sometimes a trial order before full approval. RDSO publishes its updated approved-vendor list periodically. Without this, many Railway tenders will not even evaluate your bid, however competitive the price.
• Defence: Ordnance factories, Defence PSUs and DRDO run their own vendor or source registration and quality-assurance processes (often involving DGQA inspection), specific to the item category.
• Other PSUs: many run their own supplier-registration process, sometimes a simple online form, sometimes a plant audit.

Read a tender's eligibility clause for phrases like "approved source," "registered vendor" or "vendor code" before you price it — if it names a registration you don't hold, find out whether a trial-order route or a registered sub-vendor arrangement is allowed, or treat that tender as a longer-term target rather than an immediate bid.

Make in India: Class-I and Class-II local suppliers

The Public Procurement (Preference to Make in India) Order classifies every bidder by self-certified local content:

In practice: if the lowest bid (L1) is already Class-I, it wins outright. If L1 is Class-II or non-local, the lowest Class-I bidder already in the tender is invited to match L1's price within the preference margin the order sets, and wins if it matches. Self-certifying a local-content figure you can't support is a real risk — the order allows a financial penalty if your class is found incorrect after award. Confirm the current thresholds and margin with the DPIIT order in force before you certify.

MSE purchase preference, separate from Make in India

Alongside local content, the Public Procurement Policy for MSEs gives registered Micro and Small Enterprises their own advantage: central ministries, departments and CPSUs target at least 25% of annual procurement value from MSEs, with sub-targets for women-owned and SC/ST-owned MSEs, and Udyam-registered MSEs are generally exempt from EMD and tender-document fees. The two policies stack — an MSE that is also a Class-I local supplier gets both benefits where the tender applies them. Our MSME benefits guide covers the MSE side in full.

GST on manufactured goods

Unlike a works contract, which is usually taxed as a service, a straight manufacturing supply is taxed as a supply of goods under GST, at the rate set for that product's HSN code — commonly 5%, 12%, 18% or 28% depending on the item, not a single flat rate. Input tax credit is available to a registered manufacturer on inputs and capital goods used to produce the supply. The tender's commercial terms state whether your quoted price is GST-inclusive or GST is paid extra against invoice; confirm the correct HSN rate for your specific product with your tax consultant before pricing, since it directly changes your margin.

A realistic first manufacturing tender, end to end

1. Register the basics: GST, PAN, Udyam (if applicable), and BIS/ISI certification where your product category requires it.
2. Start on GeM for catalogue-style products while you pursue department-specific vendor approval for higher-value, specification-driven work.
3. Apply for vendor/source approval early with the buyers you want to sell to repeatedly (RDSO, a Defence PSU, a specific PSU) — this is a one-time process that unlocks many future tenders, not a per-tender task.
4. Build your document vault once: registration certificates, BIS/ISO certificates, last three years' turnover and net worth, past supply orders and completion certificates, and your self-certified local-content workings.
5. Price to the specification, not just the quantity: testing, inspection charges, packing and freight to site, and the correct GST rate for the HSN code all belong in the rate, not as an afterthought.
6. Submit on the buyer's own portal (IREPS, GeM, CPPP, or the PSU's own site) with every certificate in the format asked for, and track corrigenda up to the deadline.

Grovia Tender runs steps 4 and 5 for you: Company DNA stores your registrations, certifications and financials once, eligibility is checked with evidence against each tender's actual clause (vendor-approval and local-content flags included where the tender states them), and the technical response and document checklist are drafted from your own vault. Vendor approval, testing and final pricing judgement stay with you.
