About Sinotruk spare parts: What’s the difference between original, OEM, copy, or fake?

Our company has been engaged in the sales and export of Sinotruk parts for 15 years.
Many customers have questions. How to distinguish between so many types of parts, original, OEM, aftermarket, copy, and fake? Now let’s compare them together.
1. Original parts, or Genuine parts, refer to the parts that are exactly the same as those used when producing trucks, and the packaging usually has the original logo. At the same time, original parts are divided into parts produced by Sinotruk itself and parts purchased from outside.
2. OEM, original equipment manufacturer, actually refers to the manufacturer that produces supporting parts for Sinotruk, that is, they are the supplier of Sinotruk! Customers who are very familiar with Sinotruk parts may notice that many original parts are labeled with OEM.
3. Aftermarket: Aftermarket parts are also called copy parts, which refer to those parts produced by other factories that are exactly the same but of different quality, or in other words, they are not Sinotruk suppliers, but they produce the same parts themselves. Some of these manufacturers are also of good quality, but with different brands.
4. Fakes: Fakes are parts produced by some manufacturers, which are marked with the SINOTRUK brand or logo and passed off as genuine products.
