19 CFR § 181.23 - Effect of noncompliance; failure to provide documentation regarding transshipment.
(a) Effect of noncompliance. If the importer fails to comply with any requirement under this part, including submission of a Certificate of Origin under § 181.22(b) or submission of a corrected Certificate under § 181.22(c), the Center director may deny preferential tariff treatment to the imported good.
(b) Failure to provide documentation regarding transshipment. Where the requirements for preferential tariff treatment set forth elsewhere in this part are met, the Center director nevertheless may deny preferential tariff treatment to an originating good if the good is shipped through or transshipped in a country other than the United States, Canada or Mexico and the importer of the good does not provide, at the request of the Center director, copies of the customs control documents that indicate to the satisfaction of the Center director that the good remained under customs control while in such other country.
