Example. A brings CFC-12, an ODC listed in section 4682(a)(2), into the customs territory and enters the CFC-12 for transportation and exportation. The ODC is not taxable because it is not entered for consumption, use, or warehousing. The ODC also would not be taxable if it were admitted to a foreign trade zone (rather than brought into the customs territory) for transportation and exportation.
Example. A enters CFC-113, an ODC listed in section 4682(a)(2), into the United States for consumption, use, or warehousing. A warehouses the CFC-113 and then decides to ship the ODC to its factory outside the United States (as defined in § 52.4681-1 (c)(2) ). The CFC-113 is a taxable ODC because the requirements of paragraph (b)(1)(i) of this section have been met. However, tax is not imposed on the ODC because there is no taxable event. A did not sell the ODC and, under § 52.4681-1(c)(7) , warehousing is not a use.
