This walkthrough assumes you've already confirmed this product doesn't exist in Amazon's catalog (see How to Determine Whether a Product Already Exists) and have your product identifier ready (see Understanding Product Identifiers).
Step 1: Navigate to Add a Product
From Seller Central, go to Catalog → Add Products.
Step 2: Confirm this is a new listing, not an existing one
Amazon will prompt you to search for the product before letting you create a new listing — this is the same check covered in Creating a New Listing vs. Adding an Offer. Search using your UPC/GTIN to be sure.
Step 3: Choose the correct category
Select the category that matches how comparable, well-established competitor listings are categorized (see How Category Trees Work). Amazon will show you the referral fee rate associated with your selection — use this as a sanity check.
Step 4: Complete the Vital Info tab
Fill in every required field — title, brand, product identifier, and category-specific required attributes. Required fields are typically marked distinctly from optional ones.
Step 5: Upload images meeting Amazon's requirements
Upload your main image (pure white background) and additional images. See Product Image Requirements by Marketplace for exact specs.
Step 6: Review before submitting
Compare your near-final listing against the Product Listing Optimization Checklist and the good vs. poor listing example before submitting.
Step 7: Submit and monitor
After submission, Amazon generates your ASIN and processes the listing — this can take anywhere from a few minutes to longer depending on category and current processing volume. Check back within a few hours to confirm the listing is live and not flagged; if it comes back suppressed, see How to Troubleshoot a Suppressed Listing.
