U.S. Notes (con.) (k) As provided in headings 9903.05.38, 9903.05.39, 9903.05.48, 9903.05.49, 9903.05.70, 9903.05.71 and 9903.05.73–9903.05.76, for any good of a member state of the European Union, Japan, South Korea, Switzerland or Taiwan subject to a specific or compound rate of duty under column 1-General, the ad valorem equivalent rate of duty of such good shall be determined by dividing the amount of duty payable under column 1-General by the customs value of the good. For example, if a good were subject to a specific duty of 50 cents per kilogram, and one kilogram of the good were entered with a customs value of $10, then the ad valorem equivalent rate of duty would be obtained by dividing 50 cents by $10, yielding 5 percent. For any good of South Korea for which a specific or compound rate of duty under column 1-Special is properly claimed, the ad valorem equivalent rate of duty shall be determined in the same manner. For headings 9903.05.39 and 9903.05.76, articles for which the applicable column 1 duty rate is less than 10 percent, the sum of the column 1 duty rate and the additional ad valorem rate of duty is 10 percent ad valorem. For headings 9903.05.49, 9903.05.71 and 9903.05.74, articles for which the applicable column 1 duty rate is less than 12.5 percent, the sum of the column 1 duty rate and the additional ad valorem rate of duty is 12.5 percent ad valorem.
