GeM Catalogue Upload Failed — How to Fix Product Listing Errors

Uploading your product catalogue on GeM is essential to start selling to government buyers. But sellers frequently face errors — image rejections, specification mismatches, wrong category selection, and brand approval blocks. This guide covers every common catalogue upload error and its fix.

Common Catalogue Upload Errors

• "Image upload failed" — image rejected due to format, size, or quality
• "Specification mismatch" — product specs don't match the selected category template
• "Category not applicable" — wrong product category selected
• "Brand not approved" — brand requires OEM authorization
• "OEM panel authorization required" — resellers need manufacturer approval
• "Catalogue rejected" — manual review rejected the listing
• "Duplicate catalogue" — similar product already listed by you

Fix 1: Image Format and Size Errors

GeM has strict image requirements:

1. Accepted formats — JPG, JPEG, and PNG only; no BMP, GIF, TIFF, or WebP
2. File size limit — Each image must be under 2 MB; compress large files
3. Minimum resolution — At least 500 x 500 pixels; blurry or low-resolution images are rejected
4. White background — Product images should have a clean white background for catalogue display
5. No watermarks or text — Don't add company logos, watermarks, or promotional text on the product image
6. Multiple images — Upload 2-3 images showing different angles of the product
7. Actual product photo — Use real product photos, not 3D renders or stock images

How to fix:

• Use free tools like tinypng.com to compress images below 2 MB
• Resize to at least 800 x 800 pixels for best display
• Use a white bedsheet or poster board as background for product photography
• Save as JPG at 80% quality for optimal file size

Fix 2: Specification Mismatch

Each GeM category has a predefined specification template:

1. Fill all mandatory fields — Fields marked with * are required; leaving them blank causes rejection
2. Match exact specifications — Enter specifications exactly as per your product; don't exaggerate or generalize
3. Unit of measurement — Use the exact unit the template asks for (mm, cm, kg, litres); don't enter "5 centimeters" in a "mm" field
4. Dropdown values only — Some fields have fixed dropdown options; you must select from available choices
5. Model number — Enter the exact manufacturer model number, not your internal SKU
6. BIS/ISI certification — If the category requires BIS certification, you must have it and enter the license number
7. Country of origin — Mandatory field; select accurately (Made in India products get preference)

Common mistakes:

• Entering "NA" or "N/A" in numeric fields — enter 0 if not applicable
• Mixing up "Brand Name" and "Model Name" fields
• Entering dimensions in wrong order (L x W x H)

Fix 3: Wrong Category Selected

Selecting the wrong product category causes specification template mismatch:

1. Search before browsing — Use the category search box and enter your product name or type
2. Check category hierarchy — GeM categories have multiple levels; drill down to the most specific sub-category
3. Similar but different categories — "Office Furniture" and "Educational Furniture" are different categories with different specs
4. Product vs Service — Don't list products under service categories or vice versa
5. Category mapping guide — Check GeM's product category list for the exact match

How to fix wrong category:

• You cannot change the category of an existing listing
• Delete the rejected listing and create a new one with the correct category
• Search for similar products on GeM to see which category other sellers use

Fix 4: Brand Approval Pending

Many product categories require brand authorization:

1. Brand registration — If you are the brand owner, register your brand on GeM through the seller dashboard
2. Brand authorization document — Upload the brand registration certificate (trademark registration)
3. Unregistered brands — If your brand is not trademarked, GeM may allow listing under "Unbranded" or "Generic" categories
4. Brand spelling — Ensure the brand name matches exactly with GeM's database (including capitalization and spacing)
5. Brand approval timeline — Brand registration review takes 5-7 working days on GeM

For resellers:

• You need the brand owner's authorization letter to list their products
• The brand owner must be registered on GeM and approve you through the OEM panel

Fix 5: OEM Panel Authorization

If you're a reseller, Original Equipment Manufacturer (OEM) authorization is mandatory for many categories:

1. What is OEM panel? — The manufacturer (OEM) must add you as an authorized reseller on their GeM OEM panel
2. Contact the manufacturer — Ask your supplier/manufacturer to log into their GeM seller account and add you to their OEM panel
3. OEM not on GeM — If the manufacturer isn't registered on GeM, they must register first before they can authorize resellers
4. Authorization per category — OEM authorization is category-specific; you need separate authorization for each product category
5. Authorization expiry — OEM authorizations have validity periods; check if yours has expired

Steps for OEM to authorize a reseller:

1. OEM logs into GeM seller dashboard
2. Goes to OEM Panel → Add Reseller
3. Enters the reseller's GeM seller ID
4. Selects the product categories for authorization
5. Approves the reseller

Steps for reseller after OEM authorization:

1. Log into your GeM seller dashboard
2. Check OEM Authorizations section — you should see the approved categories
3. Now upload your catalogue under the authorized categories

Fix 6: Catalogue Rejected After Review

If your catalogue passes initial upload but is rejected during review:

1. Check rejection reason — Go to Dashboard → My Catalogues → Rejected → View reason
2. Common rejection reasons:
   • Product image doesn't match specifications
   • Misleading product title or description
   • Price significantly below market rate (suspected fake listing)
   • Missing mandatory certifications (BIS, FSSAI for food items)
   • Duplicate of existing listing
3. Fix and resubmit — Correct the identified issues and upload again
4. Appeal — If you believe the rejection is incorrect, raise a ticket with supporting documents

1. Log into gem.gov.in → Seller Dashboard
2. Click "Add Catalogue" or "Upload Product"
3. Select category — Search and select the correct product category

Important Tips

1. Study existing listings — Search for similar products on GeM to understand the correct category, specs format, and pricing

3. Competitive pricing — GeM shows price comparisons; price your products competitively but realistically
4. Bulk upload — For large catalogues, use GeM's bulk upload template (Excel format) instead of adding one product at a time
5. Update regularly — Keep your catalogue updated with current prices and stock availability
