First of all, you need to know the products you produce, which country you are selling, different homes, and different requirements on the power cord standards. For example, in countries that go to Europe, the products need to have the VDE certification of the European Union. If you go to the United States, you need to have the US UL certification. You have to go to Australia, Japan, Italy, and many other countries to have relevant product certification requirements. In the same way, if this is not certain, you may not be able to use the product you have made, so this is the primary issue.
