Class Code: 3632

Per NCCI's Scopes Code Description:

Code 3632 applies to the manufacture or repair of machines as well as general job machining. It must be emphasized that Code 3632 is an NOC classification and is applied to operations only when such operations are not specifically contemplated by another classification.

Metal castings, forgings, bars, rods, flats, tubing, angles, pipe and pipe fittings, chains, sockets, gears, shafting, pulleys, hardware, sheet metal and some lumber and paint may be used. A variety of processes may be involved such as boring, turning, planing, shaping, milling, drilling, punching, grinding, tapping, threading, shearing, bending, forming, riveting, welding, painting, inspecting and testing.

Code 3632 additionally contemplates auto jacks manufacturing—not stamped; auto piston manufacturing; commercial or household laundry machinery manufacturing; stoker manufacturing; and the sharpening of industrial tools.

Additional representative operations that have been assigned to Code 3632 include the repair of diesel engines used as generators, risks engaged exclusively in the repair of either inboard or outboard motors and other small engines such as those used in lawn mowers and snowmobiles, and axle unit assembly or manufacturing or repair.

The classification applies to automotive machine shops. The term “automotive machine shops” as used in this context refers to locations where work is performed on various automobile parts which have been removed from a vehicle by others. The “automotive machine shop” does not engage in any work on vehicles or on parts while the parts are attached to vehicles. The operations may include cylinder reboring, valve grinding and turning down brake drums. See Code 3648 for shops engaged in the repair of automotive parts such as lighting, ignition and starting apparatus.

The partial or complete rebuilding of used automobile engines is assigned to Code 3632. This differs from the manufacture of new automobile engines, which is assigned to Code 3827—Automobile Engine Mfg.

Code 3632 contemplates the machining and finishing of the rough projectile shell blanks that have undergone preliminary processing by means of foundry and forging operations performed by outside entities or in separate departments operated by the shell manufacturer.

The machining operations are typical machine shop operations consisting of sawing, centering, turning, boring, facing, reaming, shaping the nose (i.e., “Nosing In” as specified in the class phraseology), heat-treating, thread milling, application of copper bands, washing, painting and packing.

Code 3632 also applies to the production of bomb cases made from sheet steel or steel tubing. In general, this involves the processing of seamless steel pipe by cutting to size and then applying heat-treating, shaping the nose and tail, welding on the bomb fin, degreasing, spray painting and packing.

The manufacture of woodworking machinery is additionally assigned to Code 3632.

Certain Code 3632 operations are designated as “not otherwise classified” (NOC). These NOC operations must apply to an insured only when no other classification more specifically describes the insured’s operations. The following is a representative list of classifications somewhat related in nature to Code 3632 operations that are not assigned to Code 3632:

3638 Ball or Roller Bearing Mfg. 3629 Machined Parts Mfg. NOC
3581 Fuel Injection Device Mfg. 3145 Screw Mfg.
3179 Electrical Apparatus Mfg. NOC 3303 Spring Mfg.
3635 Gear Mfg. or Grinding 3114 Tool Mfg.—Drop or Machine Forged—NOC—Machining or Finishing of Tools or Die Making Operations
3146 Hardware Mfg. NOC 3113 Tool Mfg.—Not Drop or Machine Forged—NOC
3400 Metal Stamped Goods Mfg. NOC 3634 Valve Mfg.
3132 Nut or Bolt Mfg. 3257 Wire Goods Mfg. NOC
3188 Plumbers’ Supplies Mfg. NOC    

In addition to this representative list, one should review sources such as the classification index in this manual to determine whether a classification other than Code 3632 or a classification other than one on the above list is applicable to the operations being reviewed for classification purposes.

State Addendum
Massachusetts Refer to Code 3648 for shops engaged in the repair of automotive lighting and ignition, and Code 3643 for shops engaged in the repair of automotive starting apparatus. Refer to Code 3612 for the manufacture of fuel pumps, super or turbochargers and fuel injectors. Code 3581—Fuel Injection Device Mfg. and Code 3303—Spring Mfg. are N/A MA.
