As of 2015, comprehensive lists of American-made products are available on websites such as AmericansWorking.com, MadeInUSAChallenge.com and MadeInUSA.org. These sites conduct thorough investigations of companies and products submitted to their sites to ensure they are made in America. They are updated consistently to maintain accurate product listings.
A product must consist of 51 percent or more of American-made parts or labor for MadeInUSA.org to classify it as made in America, regardless of the origin of the company's owner. The Federal Trade Commission states that a product must be entirely made in America to qualify for the label "Made in USA" and to use the claim on labeling and packaging.
