However, this validity period can only be until the date of annual review, because 3C certification requires annual review every year before it can continue to be used. In this way, the new company does not need to do anything else. It can be sold directly. If the annual review date comes, then the product that has passed 3C certification cannot be extended because the original company's factory is no longer available and cannot inspect the factory for annual review. The new company cannot continue to sell this product. After the new company assembles the parts into finished products, and the finished products are the products and accessories that were originally certified by 3C, then the original company's 3C certification can be used. Of course, the condition is that the original company's 3C certification is within the validity period. In this way, you can sell it directly. If the accessories of the finished product are not the original 3C certified finished product accessories, you cannot use the 3C certificate of the original company. If it cannot be used, the new company will have to re-apply.
