19 CFR § 148.55 - Exemption for articles bearing American trademark.
(a) Application of exemption. An exemption is provided for trademarked articles accompanying any person arriving in the United States which would be prohibited entry under section 526, Tariff Act of 1930, as amended (19 U.S.C. 1526), or section 42 of the Act of July 5, 1946 (60 Stat. 440; 15 U.S.C. 1124), because the trademark has been registered with the U.S. Patent and Trademark Office and recorded with Customs. The exemption may be applied to those trademarked articles of foreign manufacture bearing a trademark owned by a citizen of, or a corporation or association created or organized within, the United States when imported for the arriving person's personal use in the quantities provided in pararaph (c) of this section. Unregistered and unrecorded trademarked articles are not subject to quantity limitation.
(b) Limitations -
(1) 30-day period. The exemption in paragraph (a) of this section shall not be granted to any person who has taken advantage of the exemption for the same type of article within the 30-day period immediately prior to his arrival in the United States. The date of the person's last arrival on which he claimed this exemption shall be considered to be the date he last took advantage of the exemption.
(2) Sale of exempted articles. If an article which has been exempted is sold within one year of the date of importation, the article or its value (to be recovered from the importer), is subject to forfeiture. A sale subject to judicial order or in the liquidation of an estate is not subject to the provisions of this paragraph.
(c) Quantities. Generally, each person arriving in the United States may apply the exemption to one article of the type bearing a protected trademark. The Commissioner shall determine if a quantity of an article in excess of one may be entered and, with the approval of the Secretary of the Treasury, publish in the Federal Register a list of types of articles and the quantities of each entitled to the exemption. If the holder of a protected trademark allows importation of a quantity in excess of one of its particular trademarked article, the total of those trademarked articles authorized by the trademark holder may be entered without penalty.
