19 C.F.R. § 10.2023
(b) Effect on regional value content calculation. Packing materials and containers for shipment, as defined in § 10.2013(o), are to be disregarded in determining the regional value content of a good imported into the United States. Accordingly, in applying the build-down, build-up, or net cost method for determining the regional value content of a good imported into the United States, the value of such packing materials and containers for shipment (whether originating or non-originating) is disregarded and not included in AV, adjusted value, VNM, value of non-originating materials, VOM, value of originating materials, or NC, net cost of a good.
Example. Panamanian producer A produces good C. Producer A ships good C to the United States in a shipping container that it purchased from Company B in Panama. The shipping container is originating. The value of the shipping container determined under § 10.2016(a)(2) is $3. Good C is subject to a regional value content requirement. The transaction value of good C is $100, which includes the $3 shipping container. The U.S. importer decides to use the build-up method, RVC= (VOM/AV) × 100 (see § 10.2015(c))), in determining whether good C satisfies the regional value content requirement. In determining the AV, adjusted value, of good C imported into the U.S., paragraph (b) of this section and the definition of AV require a $3 deduction for the value of the shipping container. Therefore, the AV is $97 ($100−$3). In addition, the value of the shipping container is disregarded and not included in the VOM, value of originating materials.
