In some cases, the 50% duty on all foreign repairs made to American flag merchant vessels may be remitted. Which work does NOT come under the remitting policy of U.S. Customs?

Correct Answer: Option D — Chipping, painting, and scaling by foreign labor

U.S. Customs imposes a 50% ad valorem duty on foreign repairs to U.S.-flagged vessels. However, routine maintenance tasks performed by the crew, such as chipping, painting, and scaling, are generally exempt from this duty, as they do not constitute structural repairs or major modifications subject to the repair tax.
