GeM Product Catalogue Upload as Reseller: Complete Process

Most new sellers on the Government e-Marketplace assume that uploading a product is a simple form-filling job. Then they hit the first wall: the brand is locked, the category asks for an authorisation code, or the catalogue sits pending for weeks and finally gets rejected.

If you are selling products made by someone else, you are a reseller on GeM — and the rules for you are different from the rules for a manufacturer. This guide explains the complete GeM product catalogue upload process as a reseller, what documents you need, where sellers usually go wrong, and how to get your listings approved without repeated rejections.

What Is a GeM Product Catalogue?

A GeM product catalogue is your product's official record on the GeM portal. It contains the category, brand, model, technical specifications, images, price, warranty, delivery terms and supporting certificates.

Government buyers search and compare products using exactly these fields. When a buyer creates a direct purchase order or a bid, GeM matches the technical parameters of the requirement against the parameters in your catalogue. If your specifications are incomplete or entered in the wrong field, your product simply will not appear in the buyer's comparison — even if you have the right product in your warehouse at the right price.

So the catalogue is not a formality. It is your visibility, your eligibility and your price list, all in one place.

Can a Reseller Upload Products on GeM?

Yes, but only with the manufacturer's backing, and the extent of what you can do depends on the category.

Every GeM seller account has a reseller panel by default. What that panel allows you to do is controlled by the category quadrant — GeM classifies product categories into quadrants and applies different reseller rules to each.

Two practical takeaways from this table. First, check the quadrant of your category before you chase stock or quote a price — a category may not accept resellers at all. Second, in most reseller cases you are not creating a product from scratch; you are attaching yourself to a catalogue the manufacturer already built.

Documents and Information Required

Before you open the upload screen, keep the following ready:

Account-level requirements

• Active GeM seller account with a completed profile (PAN, GST if applicable, bank details, business registration proof)

• Category activated on your seller profile

• OEM authorisation — an authorisation code for Q2 categories, or an authorisation letter from the manufacturer where the category requires it

• Vendor assessment, where the category or the buyer's requirement demands it

Product-level information

• Exact brand name and model number as used by the OEM

• Manufacturer name and full manufacturing address

• Complete technical specifications, matching the OEM datasheet

• Country of origin and local content details

• HSN code and SKU/EAN

• Product images meeting GeM's image rules

• MRP, selling price, tax details, quantity and delivery period

• Warranty terms and after-sales support details

• Supporting certificates — BIS, ISI, test reports, energy ratings, or any certification mandatory for that category

The single most useful preparation step is to get the OEM's official datasheet or brochure in writing. Almost every specification mismatch rejection starts with a seller typing values from a dealer's WhatsApp message instead of the manufacturer's document.

GeM Product Catalogue Upload Process for Resellers

Step 1 — Complete your seller registration and profile. An incomplete profile blocks catalogue submission. Confirm your business details, bank account and GST are verified.

Step 2 — Identify the correct category and check its quadrant. GeM has thousands of categories with strict mapping. Search the category by the actual product, not by a general name.

Step 3 — Obtain authorisation from the OEM. For Q2 categories, ask the manufacturer to generate an authorisation code for you from their OEM panel. For other categories, obtain a reseller authorisation letter on the OEM's letterhead in the format GeM accepts.

Step 4 — Enter the authorisation code in your reseller panel. Log in to your GeM seller account and add the code against the relevant brand and category.

Step 5 — Wait for the OEM to validate the first pairing. For a first-time pairing, the manufacturer verifies from their panel that the code was used by the intended reseller. Later pairings in the same category with the same code are generally processed automatically.

Step 6 — Pair with the existing catalogue, or create a new one. Where the OEM has already listed the product, pair with it using the catalogue ID or the golden parameters. Where the quadrant permits a new listing, proceed to create the catalogue.

Step 7 — Fill in the product details. Enter brand, model, manufacturer details, and every technical parameter in its designated field. Do not put specifications only in the description box.

Step 8 — Upload product images. Follow GeM's image requirements — clear, actual product images on a plain background, correct dimensions, no promotional text, no stock photos from the internet.

Step 9 — Add pricing and commercial terms. Enter MRP and offer price, tax, delivery period, quantity and warranty. Keep the price realistic against MRP and consistent with what other authorised sellers of the same brand are offering.

Step 10 — Attach the required documents and certificates. Upload the authorisation document, mandatory certifications and any test reports the category demands.

Step 11 — Review and submit for approval. Re-read the brand, model and specification fields once more before submitting. Corrections after submission cost far more time than a two-minute check.

Step 12 — Track the catalogue status. In Q3 and Q4 categories the request goes to the OEM first, who must act within 72 hours. Track the status in your panel and read the rejection remarks carefully if it comes back.

Product Information a Reseller Must Enter

Common Reasons for GeM Catalogue Rejection

• Wrong category selection — the most frequent cause. A product listed under a near-matching category will not surface in buyer searches and is often rejected outright.

• Specification mismatch — values that do not match the OEM's published datasheet.

• Brand and model mismatch — model number entered differently from the OEM's catalogue.

• Incorrect manufacturer details — trader name entered instead of the actual manufacturer.

• Missing or invalid authorisation — expired letter, wrong format, or a code issued for a different reseller.

• Poor images — blurry photos, watermarks, brochure screenshots, or images that do not show the actual product.

• Missing mandatory certificates — BIS or category-specific certification not attached.

• Pricing issues — unrealistic pricing against MRP, or prices inconsistent with the brand's other sellers.

• Incomplete fields — optional-looking fields left blank that the category treats as mandatory.

How to Avoid GeM Catalogue Rejection

Confirm the quadrant and the exact category before you do anything else. Take the specification values directly from the OEM datasheet and copy them field by field rather than from memory. Keep the authorisation document valid and in the correct format, and renew it before it lapses — if an OEM invalidates an authorisation code, catalogues paired using that code are removed from the marketplace.

Upload one product first and get it approved before bulk-listing fifty. That one approval tells you exactly what the category expects. And when a rejection comes, read the recorded reason and fix that specific field instead of resubmitting the same catalogue again.

GeM Reseller Catalogue Upload vs OEM Catalogue

In short: the OEM sets the record and the reseller works within it. This is why authorisation is not paperwork you can arrange later — without it, most branded categories are closed to you.

Why Professional GeM Catalogue Management Helps

Catalogue work is repetitive, detail-heavy and unforgiving. One wrong category or one mismatched model number can stall a listing for weeks, and a rejected catalogue with a recorded reason is harder to clean up than one filed correctly the first time.

At BizHelp, our team handles GeM catalogue management and product upload end to end — category mapping, specification entry, image compliance, documentation and follow-up on pending approvals. We also help resellers arrange the OEM authorisation they need before uploading, so the catalogue does not get stuck at the approval stage.

Frequently Asked Questions

1. Can a reseller upload products on GeM?

Yes, but only with OEM backing. In Q2 categories you pair with the manufacturer's existing catalogue using an authorisation code. In Q3 and Q4 categories you may upload a new catalogue, which the OEM must approve. Q1 categories do not allow resellers.

2. What documents are required for catalogue upload?

 You need an active GeM seller account, OEM authorisation code or letter, the manufacturer's technical datasheet, product images, HSN and SKU details, and any mandatory category certification such as BIS or test reports.

3. How does a reseller add a product on GeM?

 Log in to your seller account, enter the OEM authorisation code in your reseller panel, wait for validation, then pair with the OEM's catalogue using the catalogue ID or golden parameters, or upload a new catalogue where the quadrant permits.

4. Why is my GeM catalogue rejected repeatedly?

The usual causes are wrong category selection, specifications that do not match the OEM datasheet, brand or model mismatch, invalid authorisation, or non-compliant images. Read the recorded rejection reason and correct that specific field before resubmitting.

5. Can a reseller list multiple products on GeM?

Yes. There is no fixed limit on the number of products. However, each brand and category needs its own valid authorisation, and every product must meet that category's specification and documentation requirements separately.

6. What happens after catalogue submission?

In Q3 and Q4 categories the request goes to the OEM, who must approve or reject it within 72 hours with reasons recorded. Once cleared, the catalogue moves through GeM validation and then becomes visible to government buyers.

7. Do I need an authorisation code for every category?

No. Authorisation codes are required for Q2 categories. Other quadrants may require a reseller authorisation letter instead, and some categories restrict reseller listing entirely. Check the quadrant before starting.

8. How long does GeM catalogue approval take?

Timelines vary by category and by how quickly the OEM responds. OEM approval in Q3 and Q4 is capped at 72 hours. Delays usually come from incomplete specifications or missing documents rather than the portal itself.

9. Can the OEM remove my catalogue later?

Yes. If the OEM invalidates the authorisation code you used, catalogues paired with that code are removed from the marketplace and you are notified on your panel. Keep your authorisation current and renew it before expiry.

10. Can I change the price after uploading the catalogue?

Yes, prices can be updated from your seller panel. In Q2 categories, MRP change requests are routed to the OEM for processing, so keep your pricing aligned with the brand's approved MRP from the start.

Conclusion

Uploading a product catalogue as a reseller on GeM is less about the upload screen and more about the preparation behind it. Check the category quadrant, secure valid OEM authorisation, and take your specifications straight from the manufacturer's datasheet — those three habits prevent most rejections.

Start with one product, get it approved, and use that approved listing as the template for everything else you add. A clean, correctly mapped catalogue is what keeps your products visible to government buyers and eligible when the right bid comes along.
