The Agreement on Trade Related Investment Measures (TRIMS) applies to any measure that discriminates against foreigners or foreign products. Like the GATT, it applies only to measures that affect trade in goods. It recognizes that certain measures can restrict and distort trade, and states that no member shall apply any measure that discriminates against foreigners or foreign products (i.e. violates National Treatment). It also outlaws investment measures that lead to restrictions in quantities (violating another principle in the GATT).

An illustrative list of trade-related investment measures, agreed to be inconsistent with these GATT articles, is appended to the TRIMS. The list includes measures that require particular levels of local procurement by an enterprise ("local content requirements"). It also discourages measures that limit a company's imports or set targets for the company to export ("trade-balancing requirements"). Under the agreement, countries must inform the WTO and fellow-members of all investment measures that do not conform to the agreement. Developed countries had to eliminate these by the end of 1996; developing countries had until the end of 1999; and least developed countries were given until 1 January 2002. In addition, WTO members were to consider by 1 January 2000 whether there should also be provisions on investment policy and competition policy.

In English, TRIMS (Agreement on Trade-Related Investment Measures); in French, MIC (Accord sur les Mesures concernant les Investissements et liées au Commerce).
