Before you type a single detail into the GeM portal, you have to answer one question honestly: do you make the product, or do you sell someone else's? That single answer decides which registration path you're on: Original Equipment Manufacturer (OEM) or Authorised Reseller, and getting it wrong isn't a small slip-up. It can mean blocked catalogue listings, missing authorisation codes, and bids that get rejected for a paperwork mismatch you didn't even know existed.

This is one of the first branching points anyone doing GeM registration in India runs into, and a lot of first-time sellers treat it as a formality. It isn't. Your category decides what documents you'll need, how your product listings get approved, and even how much pricing control you'll have. So before you start your GeM registration, let's actually walk through what these two categories mean, how they're different, and which one fits your business.

What Does "OEM" Actually Mean on GeM?

OEM stands for Original Equipment Manufacturer. On GeM, this term applies to the business that either physically manufactures a product or genuinely owns the brand behind it. If you've built the factory, hired the workers, and put your company's name on the box, you're an OEM.

Being registered as an OEM comes with real privileges. You can list your products directly under your own catalogue, control your brand's presence on the platform, and, most importantly, authorise other sellers to resell your products. Without your permission, nobody else can legally list your branded goods on GeM. That's the whole point of the system.

There's also a middle category worth knowing: Deemed OEM. This applies to businesses that don't manufacture in-house but outsource production to a third party, then sell the finished goods under their own brand name. Think of a company that designs furniture but has it built at a contract factory. They didn't run the machines themselves, but the brand is theirs, and GeM treats them as OEMs for registration purposes.

One thing to keep in mind: registering as an OEM typically means passing GeM's Vendor Assessment, carried out by an agency like the Quality Council of India. It's not automatic. GeM wants proof that you're really capable of manufacturing what you claim to manufacture, not just claiming the title.

What Does "Authorised Reseller" Mean on GeM?

Now flip the picture. A reseller doesn't manufacture anything. They buy finished products from an OEM, sometimes in bulk, sometimes on a case-by-case basis, and sell those same products on GeM at a standard commercial markup.

Here's the catch, though: you can't just decide to sell someone else's branded product on GeM. You need permission, and that permission comes in the form of an authorisation code or a Letter of Authorisation (LoA) issued directly by the OEM. Without it, the portal simply won't let you pair your reseller account with that product listing. No exceptions.

For a lot of product categories, especially electronics, industrial equipment, and anything considered "Q2" under GeM's classification system, the process works like this: the OEM uploads an authorization code through their own OEM Panel, and the reseller enters that code to get matched and approved. It's a digital handshake, essentially, and it exists specifically to stop unauthorised sellers from listing knockoffs or unapproved stock under a real brand's name.

If you're planning GeM registration online as a reseller, budget time for this step. Getting an OEM to issue your authorisation code isn't instant; it depends on their internal approval process, not just yours.

OEM vs Reseller — Key Differences

Let's put this side by side, because the differences are more practical than theoretical.

Who registers under each category?

• OEM: Businesses that manufacture their own products, or deemed OEMs selling outsourced goods under their own brand.
• Reseller: Traders, dealers, and distributors selling products manufactured by someone else.

Pricing control

• OEM: Sets the base price for the product across the entire platform.
• Reseller: Can adjust pricing within limits set by the OEM; you don't get a completely free hand.

Catalogue creation

• OEM: Builds the original product listing from scratch, including specifications, images, and compliance details.
• Reseller: Doesn't create a new listing. Instead, they "pair" with the OEM's existing catalogue entry once authorised.

Documentation required

• OEM: Vendor assessment, manufacturing proof, brand ownership documents.
• Reseller: Authorisation Code or Letter of Authorisation from the specific OEM whose products they want to sell.

Buyer trust and purchase preference

• Government buyers on GeM often lean toward OEM listings first, since it removes a layer of uncertainty. That doesn't mean resellers can't win business — it just means OEMs tend to have a slight edge on trust.

Category quadrant relevance

• This one confuses people up constantly, so it gets its own section next.

How Product Quadrants (Q1–Q4) Affect Your Choice

GeM sorts products into quadrants — Q1 through Q4 — and each quadrant treats the OEM-reseller relationship differently. This is honestly one of the most overlooked parts of the whole registration decision.

• Q1 categories: No reseller role exists here at all. Only the actual manufacturer can list and sell. If your product falls into Q1, the reseller path simply isn't available to you.
• Q2 categories: This is where the authorisation code system applies. OEMs upload codes; resellers use them to get paired and authorised.
• Q3 and Q4 categories: Here, OEMs directly approve or reject the catalogue listings that resellers upload. It's a bit more manual, but the same underlying principle holds — no OEM approval, no listing.

Why does this matter for your registration decision? Because the quadrant your product falls under determines exactly what kind of authorisation paperwork you'll need and when. Checking your product's quadrant before you start your GeM registration India journey saves you from applying under the wrong assumption and having to backtrack later.

Which One Should You Register As? Practical Scenarios

Abstract rules are one thing. Real situations make this a lot clearer. Here are three common scenarios:

Scenario 1: You manufacture your own products 

Say you run a small furniture factory in Jodhpur, and every chair leaving your warehouse was built on your own floor. You're a textbook OEM. Register under that path, and once you clear the Vendor Assessment, you'll be able to list directly and even authorise other sellers to resell your furniture line if you want to expand your reach.

Scenario 2: You outsource manufacturing but sell under your own brand 

Maybe you design stationery products, but a contract manufacturer actually produces them. You're not lying about your capability; you're just not running the machines yourself. This is the Deemed OEM path. You'll still need to prove the brand is genuinely yours and that your outsourcing arrangement is legitimate.

Scenario 3: You're a distributor selling an established electronics brand

You don't manufacture laptops or printers. You buy them from a known brand and sell them to government departments through GeM. This is the reseller path, plain and simple. You'll need an authorisation letter from that specific brand, and if you're bidding on multiple tenders for the same product, don't assume one generic letter covers everything. Many tenders require authorisation tied to that specific bid.

What Happens If You Choose the Wrong Category?

This isn't a hypothetical warning — it happens often enough that it's worth spelling out clearly.

If you register as an OEM without actually manufacturing anything, your vendor assessment will likely fail, and you'll be stuck reapplying. If you register as a reseller but try to list a product without a valid authorisation code, GeM's system will simply block the listing. It won't let you bypass this with a workaround.

Even worse, some sellers realise the mismatch only after they've already built out part of their profile and started uploading documents. At that point, fixing it isn't a quick edit; it can mean a partial rebuild of your entire seller profile, plus the time lost waiting for a second round of approvals. If you're bidding against a deadline, that delay can cost you the tender entirely.

The smarter move is deciding your category honestly, upfront, based on what your business actually does, and not what sounds more impressive on paper.

Getting Your GeM Category Right the First Time

Here's the part worth remembering: this decision isn't a checkbox you fill in and forget. It shapes your entire experience on the platform: what you can list, how fast your approvals move, and whether your bids get rejected over a technicality that had nothing to do with your actual product quality.

If you're unsure which path applies to your business, especially if you're somewhere in between, like outsourcing part of your production, it's worth getting a second opinion before you submit anything. That's exactly where professional GeM registration services earn their keep. A good provider will look at how your business actually operates, confirm your product's quadrant classification, and make sure you're gathering the right documents — Vendor Assessment for OEMs and Authorisation Letters for resellers — before you're deep into the process.

At Services Plus, our GeM registration services start with exactly this kind of clarity, so you're not guessing your way through a category decision that's genuinely hard to reverse once you've begun.

Frequently Asked Questions

Can one business register as both OEM and Reseller on GeM?

Yes, this is possible if your business genuinely operates both ways: manufacturing some products while also reselling others under separate authorisation. Each product line follows its own documentation path.

Is an OEM Authorisation Code the same as an OEM Certificate?

No. An OEM certificate proves that a company is the actual manufacturer of a product. An OEM Authorisation Code (or Letter) is permission given to a reseller to represent that manufacturer's product, often tied to a specific category or even a specific tender.

Do resellers need a new authorization letter for every tender?

Often, yes. Many tenders require authorisation tied to that specific bid, not just a general reseller agreement. Always check the tender requirements before assuming an older letter still applies.

What is a "Deemed OEM", and how is it different from a regular OEM?

A Deemed OEM outsources manufacturing to a third party but sells the product under its own brand. A regular OEM manufactures in-house. Both are treated as OEMs on GeM, but a deemed OEM usually needs to show proof of its outsourcing arrangement along with brand ownership.

Does every product category require an OEM authorisation code?

No. This mainly applies to Q2 categories. Q1 categories don't allow resellers at all, while Q3 and Q4 categories use a slightly different process where OEMs approve reseller catalogue uploads directly rather than issuing a code.

What documents does an OEM need for GeM registration?

Typically, proof of manufacturing capability, brand ownership documents, GST and PAN details, and successful completion of the Vendor Assessment conducted by an agency like the Quality Council of India.

Can a reseller set their own price on GeM?

Within limits. The OEM usually sets a base price, and the reseller can adjust it slightly, but they don't have unrestricted pricing freedom the way an OEM does.

What happens if my product's quadrant doesn't match my registration category?

Your catalogue listing will likely get blocked, or your bid may be rejected on a technicality. It's best to confirm your product's quadrant classification before starting your GeM registration online, not after.

Is it harder to get approved as an OEM compared to a reseller?

Generally, yes, because OEM approval involves the vendor assessment process, which checks manufacturing capability. Reseller approval mostly depends on getting a valid authorisation code or letter from the OEM, which is usually a faster process.

Should a new business start as a reseller before becoming an OEM?

Not necessarily a rule, but it's a common path. Some businesses start by reselling an established brand's products to understand how GeM works, then move toward OEM registration once they start manufacturing their own line.
