Machine Shops

This category includes establishments known as machine shops primarily engaged in machining metal and plastic parts and parts of other composite materials on a job or order basis. Generally machine shop jobs are low volume using machine tools, such as lathes (including computer numerically controlled); automatic screw machines; and machines for boring, grinding, milling, and additive manufacturing.

Other Communications Equipment Manufacturing

Establishments in this category are primarly engaged in manufacturing communications equipment (except telephone apparatus, radio and television broadcast equipment, and wireless communications equipment).

Illustrative Examples:

Fire detection and alarm systems manufacturing
Signals (e.g., highway, pedestrian, railway, traffic) manufacturing
Intercom systems and equipment manufacturing
Video-based stadium displays manufacturing

Printed Circuit Assembly (Electronic Assembly) Manufacturing

This includes establishments primarily engaged in loading components onto printed circuit boards or who manufacture and ship loaded printed circuit boards. Also known as printed circuit assemblies, electronics assemblies, or modules, these products are printed circuit boards that have some or all of the semiconductor and electronic components inserted or mounted and are inputs to a wide variety of electronic systems and devices.

Other Electronic Component Manufacturing

This includes establishments primarily engaged in manufacturing electronic components (except bare printed circuit boards; semiconductors and related devices; electronic capacitors; electronic resistors; coils, transformers, and other inductors; connectors; and loaded printed circuit boards).

Illustrative Examples:

Crystals and crystal assemblies, electronic, manufacturing
Electron tubes manufacturing
LCD (liquid crystal display) unit screens manufacturing
Microwave components manufacturing
Piezoelectric devices manufacturing
Printed circuit laminates manufacturing
Switches for electronic applications manufacturing
Transducers (except pressure) manufacturing

Electromedical and Electrotherapeutic Apparatus Manufacturing

This includes establishments primarily engaged in manufacturing electromedical and electrotherapeutic apparatus, such as magnetic resonance imaging equipment, medical ultrasound equipment, pacemakers, hearing aids, electrocardiographs, and electromedical endoscopic equipment.

Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables

This includes establishments primarily engaged in manufacturing instruments and related devices for measuring, displaying, indicating, recording, transmitting, and controlling industrial process variables. These instruments measure, display, or control (monitor, analyze, and so forth) industrial process variables, such as temperature, humidity, pressure, vacuum, combustion, flow, level, viscosity, density, acidity, concentration, and rotation.

Analytical Laboratory Instrument Manufacturing

This includes establishments primarily engaged in manufacturing instruments and instrumentation systems for laboratory analysis of the chemical or physical composition or concentration of samples of solid, fluid, gaseous, or composite material.

Current-Carrying Wiring Device Manufacturing

This includes establishments primarily engaged in manufacturing current-carrying wiring devices.

Illustrative Examples:

Bus bars, electrical conductors (except switchgear-type), manufacturing
GFCI (ground fault circuit interrupters) manufacturing
Lamp holders manufacturing
Lightning arrestors and coils manufacturing
Receptacles (i.e., outlets), electrical, manufacturing
Switches for electrical wiring (e.g., pressure, pushbutton, snap, tumbler) manufacturing

All Other Miscellaneous Electrical Equipment and Component Manufacturing

This includes establishments primarily engaged in manufacturing industrial and commercial electric apparatus and other equipment (except lighting equipment, household appliances, transformers, motors, generators, switchgear, relays, industrial controls, batteries, communication and energy wire and cable, wiring devices, and carbon and graphite products). Examples of products made by these establishments are power converters (i.e., AC to DC and DC to AC), power supplies, surge suppressors, and similar equipment for industrial-type and consumer-type equipment.

Illustrative Examples:

Appliance cords made from purchased insulated wire
Battery chargers, solid-state, manufacturing
Door opening and closing devices, electrical, manufacturing
