eBay is a perfect platform for selling used auto parts. Those who are looking for discontinued parts and accessories know that it would be difficult to find them in regular stores. Marketplaces are the obvious solution. For this category, the quality of photos matters a lot: the degree of wear must be clearly visible on your pictures.

How to begin selling internationally

Seasoned sellers recommend starting with auto parts of medium or small size. It takes time and practice to learn how to pack them correctly. A large size of a parcel can also cause shipping issues. While trying to find out the cause of delays or returns, you will lose time, displease your customers and get bad feedback. For beginners, it’s especially important to keep their seller rating high.

How to choose auto parts suppliers

If you are selling new parts, they must be original. Counterfeit products aren’t allowed on eBay, and your account can be blocked for violating this policy. That is why you should choose your suppliers carefully. Official representatives of large companies are the best option.


If you want to sell quality goods for a competitive price, consider purchasing auto parts directly from the manufacturer. It is especially effective if you specialize in certain makes or vehicle types. Direct purchase from manufacturers also helps you avoid additional surcharges of wholesalers.

Beginners might think: the more suppliers, the better, because buyers have wider choice of auto parts! In fact, product ranges of different suppliers often overlap, differing only in margins. Besides, if you have just a few partners, you can place larger orders with each of them, and thus obtain more favorable terms. Auto parts suppliers usually have a volume-based discount system. You should bear this in mind when choosing your partners.


When discussing cooperation with a potential partner, be sure to find out which items are always in stock, and which ones are supplied to order. It is also important to ask what shipping company they work with. To streamline logistics, it’s recommended to find a supplier with storage facilities in your city. As a result, you will be able to ship orders faster.

How to check parts compatibility

The key peculiarity of the auto parts market is its large product grid. To find the right part, one needs to know all the necessary parameters. A good supplier provides exhaustive information about each product. It usually includes:

  • The part name according to SKU and other international classifications
  • Country of manufacture
  • High resolution photos and a dimensioned drawing

When creating a listing on eBay, you must specify the MPN (Manufacturer’s Part Number).

It’s extremely important to have full and precise information about compatibility, so that you know what vehicles can use a certain part. Sometimes suppliers don’t provide such data, but thankfully eBay has its own extensive catalog of parts compatibility. When listing an auto part that is featured in this catalog, eBay automatically adds relevant information to the listing (make changes if necessary).

On eBay, it’s also possible to specify compatible vehicles manually.

Why it is important to create a Returns policy

Auto parts is a category that is far more diverse and complicated than any other one. For example, many parts under the hood (such as the distributor cap) can have different connector positions depending on the vehicle make and year. That is why seemingly identical parts can be absolutely incompatible, and there is always a risk of making a mistake. It would be reasonable to think about such situations when choosing your supplier. Make sure that your partnership agreement clearly sets out flexible return conditions.

Offer a generous return policy to stay competitive and keep your buyers happy. To learn more about returns on eBay, please read this article.
