OEM Registration — What It Is, Who Requires It, and Why It Unlocks Larger Orders
OEM registration is the formal process by which a manufacturer gets recognised by a specific buyer — a government department, PSU, defence establishment, or large corporation — as an authorised Original Equipment Manufacturer of a specific product. Once registered, the OEM is placed on the buyer's Approved Vendor List (AVL) as a manufacturer, qualifying for manufacturer-specific tenders, rate contracts, direct purchase orders, and R&D partnerships.
Without OEM registration, you are treated as a trader. With it, you qualify for manufacturer-restricted tenders, rate contracts, and direct purchase orders — often at significantly better margins and with lower competition.
Key Differentiator — Manufacturer vs Trader
The core purpose of OEM documentation is to prove you manufacture the product. Factory registration, machinery list, manufacturing process flow, test reports, and BIS/product certification together establish this. Missing any of these is the most common reason OEM applications are rejected.
Who Should Register as an OEM?
Indian Manufacturers
Designing, developing, and manufacturing products under your own brand.
