Industries in the Miscellaneous Manufacturing subsector make a wide range of products that cannot readily be classified in specific NAICS subsectors in manufacturing. Processes used by these establishments vary significantly, both among and within industries. For example, a variety of manufacturing processes are used in manufacturing sporting and athletic goods that include products, such as tennis racquets and golf balls. The processes for these products differ from each other, and the processes differ significantly from the fabrication processes used in making dolls or toys, the melting and shaping of precious metals to make jewelry, and the bending, forming, and assembly used in making medical products.
The industries in this subsector are defined by what is made rather than how it is made. Although individual establishments might be appropriately classified elsewhere in the NAICS structure, for historical continuity, these product-based industries were maintained. In most cases, no one process or material predominates for an industry.
Establishments in this subsector manufacture products as diverse as medical equipment and supplies, jewelry, sporting goods, toys, and office supplies.
The subsector's revenue for the year 2008 was approximately $153.5 billion USD, with an estimated gross profit of 38.97%. Import was valued at $98.1 billion USD from 223 countries. The subsector also exported $59.9 billion USD worth of merchandise to 188 countries. Adding import value to and subtracting export value from the subsector's shipment value, the total domestic demand for the subsector in 2008 was $191.8 billion USD.
