26 CFR § 1.927(d)-2T - Temporary regulations; definitions and special rules relating to Foreign Sales Corporation.
(a) Definition of related supplier. For purposes of sections 921 through 927 and the regulations under those sections, the term “related supplier” means a related party which directly supplies to a FSC any property or services which the FSC disposes of in a transaction producing foreign trading gross receipts, or a related party which uses the FSC as a commission agent in the disposition of any property or services producing foreign trading gross receipts. A FSC may have different related suppliers with respect to different transactions. If, for example, X owns all the stock of Y, a corporation, and of F, a FSC, and X sells a product to Y which is resold to F, only Y is the related supplier of F. If, however, X sells directly to F and Y also sells directly to F, then, as to the transactions involving direct sales to F, each of X and Y is a related supplier of F.
(b) Definition of related party. The term “related party” means a person which is owned or controlled directly or indirectly by the same interests as the FSC within the meaning of section 482 and § 1.482–1(a).
