(a) Calculating the value of materials. Except as provided in §10.541, for purposes of calculating the regional value content of a good under General Note 25(o), HTSUS, and for purposes of applying the de minimis (see §10.533 of this subpart) provisions of General Note 25(o), HTSUS, the value of a material is:

(1) In the case of a material imported by the producer of the good, the adjusted value of the material;

(2) In the case of a material acquired by the producer in the territory where the good is produced, except for a material to which paragraph (a)(3) of this section applies, the adjusted value of the material with reasonable modifications to the provisions of the Customs Valuation Agreement so as to permit their application to the domestic acquisition by the producer. Such reasonable modifications include, but are not limited to, treating a domestic purchase by the producer as if it were a sale for export to the country of importation; or

(3) In the case of a self-produced material, or in a case in which the relationship between the producer of the good and the seller of the material influenced the price actually paid or payable for the material, including a material obtained without charge, the sum of:

(i) All expenses incurred in the production of the material, including general expenses; and

(ii) A reasonable amount for profit.

(b) Permissible additions to, and deductions from, the value of materials—(1) Additions to originating materials. For originating materials, the following expenses, if not included under paragraph (a) of this section, may be added to the value of the originating material:

(i) The costs of freight, insurance, packing, and all other costs incurred in transporting the material to the location of the producer;

(ii) Duties, taxes, and customs brokerage fees on the material paid in the territory of one or both of the Parties, other than duties and taxes that are waived, refunded, refundable or otherwise recoverable, including credit against duty or tax paid or payable; and

(iii) The cost of waste and spoilage resulting from the use of the material in the production of the good, less the value of renewable scrap or by-product; and

(2) Deductions from non-originating materials. For non-originating materials, if included under paragraph (a) of this section, the following expenses may be deducted from the value of the non-originating material:

(i) The costs of freight, insurance, packing, and all other costs incurred in transporting the material to the location of the producer;

(ii) Duties, taxes, and customs brokerage fees on the material paid in one or both of the Parties, other than duties and taxes that are waived, refunded, refundable or otherwise recoverable, including credit against duty or tax paid or payable;

(iii) The cost of waste and spoilage resulting from the use of the material in the production of the good, less the value of renewable scrap or by-products;

(iv) The cost of processing incurred in the territory of Singapore or the United States in the production of the non-originating material; and

(v) The cost of originating materials used in the production of the non-originating material in the territory of Singapore or the United States.

(c) Accounting method. Any cost or value referenced in General Note 25, HTSUS and this subpart, must be recorded and maintained in accordance with the Generally Accepted Accounting Principles applicable in the territory of the country in which the good is produced (whether Singapore or the United States).
