Last night U.S. Customs and Border Protection issued a CSMS on the steel and aluminum tariffs that came into effect today, using some very specific language toward foreign-trade zones.

All steel and aluminum imports subject to Section 232 duties must be admitted under Privileged Foreign (PF) status as of today, March 23. In addition, any steel or aluminum imports admitted under PF status prior to March 23 are still subject to the additional 25% steel tariff and 10% aluminum tariff.
