15 U.S.C. § 63 — Acquisition of stock of export trade corporation

This section carves out an exception to section 18 of this title, which normally restricts one corporation from acquiring another's stock. It says section 18 should not be read to forbid a corporation from acquiring or owning all or part of the stock or capital of another corporation, as long as that other corporation was organized solely to engage in export trade and is actually engaged solely in that export trade. But this exception has a limit: it doesn't apply if the effect of the acquisition or ownership would be to restrain trade or substantially lessen competition within the United States.
