How to Bulk Add Up to 25,000 Existing ASINs to Your Amazon Catalog

Want to sell products that already exist on Amazon? In Seller Central, you'd search for each ASIN, click "Sell this product," fill in your offer, and repeat — one at a time. For a catalog of hundreds or thousands of products, that's hours of manual work.

SellerSheet lets you add up to 25,000 existing ASINs to your catalog in a single submission from Google Sheets. The whole process takes three steps:

1. Check eligibility — verify you're approved to sell each ASIN.
2. Fill in SKUs & ASINs — set productType to PRODUCT and add your SKU/ASIN pairs.
3. Submit to Amazon — one click, up to 25,000 SKUs per submission.

PrerequisitesCopy Anchor Link

• Store connected: your Amazon store is connected under Settings → Stores & Marketplaces in the SellerSheet app.
• Sidebar installed: the SellerSheet add-on is installed in Google Sheets. If not, follow Install & first sync.
• A list of ASINs: the ASINs you want to add, plus your own SKU for each.

Step 1: Check selling eligibilityCopy Anchor Link

Some ASINs are restricted — they require approval, brand gating, or category ungating before you can sell them. Finding out after submission wastes time, and in Seller Central you'd have to check each one individually.

Before adding ASINs, check that you're approved to sell them with the Restriction Check sheet in your SellerSheet Catalog spreadsheet:

1. Go to the Restriction Check sheet tab.
2. Enter your stores and ASINs in the Store and ASIN columns, and pick a Reason Locale (the language of Amazon's reasons) on every row.
3. Click Get Restrictions in the sidebar.
4. Review the Status column — ALLOWED ASINs are ready to add. APPROVAL_REQUIRED rows have an Approval Link to apply in Seller Central, and RESTRICTED rows say why in Reasons.

Step 2: Prepare and fill in your SKUsCopy Anchor Link

Now switch to the Publish Queue sheet tab. Since you're adding existing products (not creating new ones), the setup is minimal:

1. Set Store (A3) and Listing Locale (B3) for your marketplace.
2. Write PRODUCT in the Product Type column (D) for each row, from row 7 down.
3. Click Get Template in the sidebar — this loads the PRODUCT template (very few columns needed).
4. Set Operation Type to UPDATE in column C for each row.
5. Fill in your SKU (column B) — your own identifier for each product.
6. Fill in the ASIN of each row in its Merchant Suggested ASIN column.

Why productType = PRODUCT?Copy Anchor Link

PRODUCT is the simplest productType — designed for matching existing catalog products. Since the product already exists on Amazon (with title, brand, images and so on), you only need to provide your SKU and the ASIN. Amazon handles the rest.

Optionally, you can also fill in your offer (price) and the condition (new/used) if you want to set them during submission.

Step 3: Submit and track resultsCopy Anchor Link

Which button you click depends on how many SKUs you're submitting:

Tracking your submissionCopy Anchor Link

1. Go to the Submission Log sheet tab.
2. Find your submission row.
3. For Submit Feed: click Refresh Status in the sidebar until the Feed Status shows the feed is finished.
4. Check the Result and Issues columns — they show success or error details for each SKU.

Tips for maximum efficiencyCopy Anchor Link

• Always check restrictions first: submitting restricted ASINs wastes time. Check eligibility in the Restriction Check sheet before filling in the Publish Queue.
• Batch your submissions: prepare all your SKU/ASIN pairs in the sheet first, then submit in one click. No need to submit row by row.
• Update price or title later with PARTIAL_UPDATE: once your ASINs are in your catalog, use the PARTIAL_UPDATE operation type to update specific attributes like price, title or images without re-submitting everything.
• Need full listing control? See How to Bulk Create & Revise Amazon Listings for creating new listings, updating attributes, managing variations and cross-marketplace expansion. Every button of the panel is listed on Catalogs.
