Auto parts export to Malaysia need form e

We are an auto parts company in Shanghai. All the time, we have exported our products to Malaysia. Before that, other customers have never asked for form e certificate of origin. Last month, we talked about a new customer. Now, the customer has placed an order, and the customer mentioned in the email that he asked for form E certificate of origin, I think it's very strange, but in order to deal with the transaction and ensure that the customer can smoothly clear the customs and pick up the goods, the customer has been promised to apply for the form e certificate of origin. But now I would like to ask how to apply for the form e certificate of origin for the export of auto parts to Malaysia?
