As one would guess Automotive parts are a very lucrative product to sell on Amazon but they are also subject to fraud, counterfeiting and other problems so this is an amazon gated category. Brands such as BMW, Mercedes Benz, Chevrolet and Ford among thousands of others allow for a multitude of automotive parts to be sold once you are ungated for this category. Even accessories such as air fresheners, automotive tools and car wash accessories are all restricted unless you are ungated for this category.
You can either source your own private label automotive parts or you can find other retailers/wholesalers and use them for amazon arbitrage, both have their advantages and both are very profitable. Even when you are ungated though there will still be certain brands that you can’t sell online unless you become an authorized dealer.
Amazon will inform you of this when you create your product listing but do keep this in mind when purchasing products so you don’t get stuck with a large amount of inventory that you can’t sell.
In general 80% or more of automotive products are NOT brand restricted.
