The Northern Mariana Islands had successfully used its position as a free trade area with the U.S., while at the same time not being subject to the same labor laws. For example, the $3.05 per hour minimum wage in the Commonwealth, which lasted from 1997 to 2007, was lower than in the U.S. and some other worker protections are weaker, leading to lower production costs. That allowed garments to be labeled "Made in USA" without having to comply with all U.S. labor laws.

However, the lifting of World Trade Organization restrictions on Chinese imports to the U.S. in 2005 had put the Commonwealth-based trade under severe pressure, leading to a number of recent factory closures. Adding to the U.S.-imposed scheduled wage increases, the garment industry is expected to become extinct by 2009.17 - dated info Agricultural production, primarily of tapioca, cattle, coconuts, breadfruit, tomatoes, and melons exists, but is relatively unimportant in the economy.
