Example to paragraph (b)(4): Synthetic rutile that is shown by appropriate analysis in the entry papers to be 91.7% pure titanium dioxide is imported and dutiable at a 5% ad valorem duty rate. The amount of imported synthetic rutile is 30,000 pounds with an entered value of $12,000. The total duty paid is $600. Titanium in the synthetic rutile is designated as the basis for a drawback claim under 19 U.S.C. 1313(b) . The amount of titanium dioxide in the synthetic rutile is determined by converting the purity percentage (91.7%) to its decimal equivalent (.917) and multiplying the entered amount of synthetic rutile (30,000 pounds) by that decimal equivalent (.917 * 30,000 = 27,510 pounds of titanium dioxide contained in the 30,000 pounds of imported synthetic rutile). The titanium, based on atomic weight, represents 59.93% of the constituents in titanium dioxide. Multiplying that percentage, converted to its decimal equivalent, by the amount of titanium dioxide determines the titanium content of the imported synthetic rutile (.5993 * 27,510 pounds of titanium dioxide = 16,486.7 pounds of titanium contained in the imported synthetic rutile). Therefore, up to 16,486.7 pounds of titanium is available to be designated as the basis for drawback. As the per-unit duty paid on the synthetic rutile is calculated by dividing the duty paid ($600) by the amount of imported synthetic rutile (30,000 pounds), the per-unit duty is two cents of duty per pound of the imported synthetic rutile ($600 ÷ 30,000 = $0.02). The duty on the titanium is calculated by multiplying the amount of titanium contained in the imported synthetic rutile by two cents of duty per pound (16,486.7 * $0.02 = $329.73 duty apportioned to the titanium). The product is then multiplied by 99% to determine the maximum amount of drawback available ($329.73 * .99 = $326.44). If an exported titanium alloy ingot weighs 17,000 pounds, in which 16,000 pounds of titanium was used to make the ingot, drawback is determined by multiplying the duty per pound ($0.02) by the weight of the titanium contained in the ingot (16,000 pounds) to calculate the duty available for drawback ($0.02 * 16,000 = $320.00). Because only 99% of the duty can be claimed, drawback is determined by multiplying this available duty amount by 99% (.99 * $320.00 = $316.80). As the oxygen content of the titanium dioxide is 45% of the synthetic rutile, if oxygen is the designated merchandise on another drawback claim, 45% of the duty claimed on the synthetic rutile would be available for drawback based on the substitution of oxygen.
