Trading industries are those that sell their products and services outside of the community, whether elsewhere in the U.S. or internationally.
Typical examples are the manufacturing, high-technology and entertainment sectors.
Local industries are those that depend on the vitality of these trading industries for growth. Generally, wholesalers, retailers, health care providers and local services are local industries. This is a misnomer. Any company that sells its products or services outside of its local area is a trading business. Let's take a CPA firm in Santa Clarita Valley whose client base is primarily located in the San Fernando Valley.
