19 C.F.R. § 152.106
(a) Elements. The computed value of imported merchandise is the sum of:
(b) Special rules.
(c) Profit and general expenses. The amount for profit and general expenses will be taken as a whole. If the producer's profit figure is low and general expenses high, those figures taken together nevertheless may be consistent with those usually reflected in sales of imported merchandise of the same class or kind.
(e) Merchandise of same class or kind. Sales for export to the United States of the narrowest group or range of imported merchandise, including the merchandise being appraised, will be examined to determine usual profit and general expenses. For the purpose of computed value, merchandise of the same class or kind must be from the same country as the merchandise being appraised.

The transaction between the foreign shipper and the U.S. importer is determined to have been affected by the relationship. There is no identical or similar merchandise from the same country of production. The U.S. importer further processes the product and sells the finished product to an unrelated buyer in the U.S. within 180 days of the date of importation. No assists from the unrelated U.S. buyer are involved, and the type of processing involved can be accurately costed. The U.S. importer has requested that the shipment be appraised under computed value. The profit and general expenses figure for the same class or kind of merchandise in the country of exportation for export to the U.S. is known. How should the merchandise be appraised?The merchandise should be appraised under computed value, using the company's profit and general expenses if not inconsistent with those usually reflected in sales of merchandise of the same class or kind.
