The Foreign-Trade Zones Board is part of the U.S. Department of Commerce and is responsible for administration of the foreign-trade zone program at the federal level.
State and Local
In Michigan, there are seven U.S. Customs ports of entry (Detroit, Battle Creek, Flint, Grand Rapids, Lansing, Port Huron, and Sault Ste. Marie), each with its own foreign-trade zone grant area. Greater Detroit Foreign-Trade Zone, Inc. (GDFTZ) administers Foreign-Trade Zone No. 70, which includes Wayne, Oakland, Macomb, Washtenaw, Monroe, Lenawee, and Livingston counties.
U.S. Customs and Border Protection Service
Once a site is granted zone status, it must be activated by the local U.S. Customs and Border Protection Service (CBP) before it can be used. Zone activity remains under the supervision of CBP.
