Below is the latest. New CBP Guidance As explained in our previous client alert, Section 307 of the Tariff Act of 1930 (19 U.S.C. § 1307) prohibits the importation of merchandise mined, produced or manufactured, wholly or in part, in any foreign country by forced or indentured labor — and since 2016, CBP has ramped up its enforcement. Most recently, on January 13, 2021, CBP issued a withhold/release order (WRO) directing all personnel at all U.S. ports of entry to detain cotton and tomato products grown or produced by any entities operating in Xinjiang. In conjunction with the announcement, CBP cited examples of “downstream products” that are covered by the order including apparel, textiles, tomato seeds, canned tomatoes, tomato sauce and other goods made with cotton and tomatoes that are produced in whole or in part in Xinjiang.
