• You must have:

  • Registered trademark (or in process)

  • Brand logo and packaging with your brand name

Step 2: Go to Seller Central

Inventory → Add a Product → I’m adding a product not sold on Amazon

Step 3: Create a New Listing

Fill out:

• Product title

• Brand name (must match packaging)

• Manufacturer name (can be your business name)

• Category selection

• Product description & bullet points

• Search terms (SEO keywords)

• Images (1000x1000px minimum)

• Price, SKU, condition

• Product ID (UPC, EAN, or GTIN)

  • If you don’t have a barcode, you can apply for a GTIN exemption

Step 3: Enter Offer Details

• Quantity

• Shipping method (FBA/FBM)

• SKU

Click Save and Finish.

✅ You’ll now be competing on the same product detail page with other sellers.

3. Can You Sell Products from Other Brands on Amazon?

Yes, but there are important rules.

✅ You Can Sell:

• Branded products you legally own and purchased from authorized distributors

• As “New” if they're sealed, undamaged, and unused

❌ You Cannot Sell:

• Counterfeit, unlicensed, or fake goods

• “Ungated” brands or categories unless approved

• Used products labeled as new

🧾 What You May Need to Sell Other Brands

Some categories and brands require approval (gating).

📦 What Is the “Buy Box” & How Do I Compete?

Factors for Winning the Buy Box:

• Competitive price

• Fast and reliable shipping (FBA preferred)

• High seller rating

• Order defect rate

• Inventory availability

Bonus Tips to Avoid Listing Errors

✅ Make sure product titles match packaging exactly✅ Avoid keyword stuffing in bullet points✅ Do not use restricted images or logos you don’t own✅ Use only your registered brand in listings✅ Keep UPC/EAN codes clean and unused elsewhere

Final Thoughts

Selling on Amazon in 2025 offers three powerful options:

1. Private label your own brand (build long-term value)

2. List on existing ASINs (fast, easy entry)

3. Sell other brands (with authorization)

Understanding how each method works, and staying compliant with Amazon’s policies, ensures your account remains healthy and profitable.

Important Note:When selling products under your own brand or unbranded items, manual product listing is required. If you intend to sell a product that belongs to another brand, Amazon will require specific documents related to the ASIN you want to list. Without these documents, selling another brand’s product is not allowed.

Never sell counterfeit or low-quality products.Amazon has strict policies and expects full compliance.If you experience confusion or uncertainty, it is strongly recommended to review Amazon’s official policies.
