Regarding preferential origin, we purchase an EU produced, but not preferential origin (no supplier declaration) material under HTS 2921 and in the EU we use this material to manufacture a product with HTS 3908. Is it possible to claim preferential origin of the end-product? The origin rule for the end-product is:
RULE 1: Manufacture in which the value of all materials of Chapter 39 used does not exceed 20% of the ex-works price of the product. However, for products composed of materials classified in headings 3901 to 3906 on the one hand, and 3907 to 3911 on the other hand, this restriction only applies to that group of materials which predominates by weight in the product
RULE 2: manufacture in which the value of all the materials used does not exceed 25% of the ex-works price of the product.
