Class Code: 3629
Per NCCI's Scopes Code Description:
Code 3629 employers will generally engage in significant amounts of both inspection and quality control work.
Additive manufacturing, also known as 3D printing, is assigned to Code 3629 when the employer’s operations and manufactured parts meet all of the criteria listed in the phraseology.
Additive manufacturing allows for the highly automated production of parts using a base material, such as plastic, wood, or metal, and a binder or adhesive. Thin layers of material are placed on top of each other using computer-controlled distribution. The base material is built up by adding the binder between each layer. The process is repeated until the part is complete. By adding only enough material that is needed to complete the part, the process results in little to no waste.
Additive manufacturing machines are capable of producing any type of part that can be programmed into the computer. This is a “clean” type of manufacturing since almost all of the work is performed by the machine. Work areas are clean and free of debris such as metal shavings, dirt, and grease found in traditional manufacturing plants. It is expected that most of the staff needed to support this technology will be in the areas of design and computer programming, with minimal production work done by individuals.
Code 3629 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 3629 operations that are not assigned to Code 3629:
|Ball or Roller Bearing Mfg.
|Plumbers’ Supplies Mfg. NOC
|Fuel Injection Device Mfg.
|Electrical Apparatus Mfg. NOC
|Gear Mfg. or Grinding
|Tool Mfg.—Drop or Machine Forged NOC—Machining or
Finishing of Tools or Die Making Operations
|Hardware Mfg. NOC
|Tool Mfg.—Not Drop or Machine Forged NOC
|Machine Shop NOC
|Metal Stamped Goods Mfg. NOC
|Wire Goods Mfg. NOC
|Nut or Bolt Mfg.
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 3629 or a classification other than one on the above list is applicable to the operations being reviewed for classification purposes.
Code 3629, is intended to apply to precision machined parts manufacturing, not precision machine manufacturing. The fifty percent or more of all machining operations performed by the risk are held to tolerances of .001 inches or closer. This 50% criterion is intended to recognize that very few insureds within the precision machined parts manufacturing industry are engaged solely in precision machining and that a precision machine shop may engage in general machining work as described by Code 3632—Machine Shop NOC, as well as Code 3629 activities. Additive manufacturing, also known as 3D printing, is assigned, by analogy, to Code 3629. Its application is highly restrictive. An employer is disqualified from being assigned to Code 3629 in all of the following conditions: the operations conducted or parts and/or finished products manufactured are described by other classifications; any assembly operations, and/or casting, forging, stamping, forming, or fabrication are conducted.
Refer to Code 3612 for the manufacture of fuel pumps, super or turbochargers and fuel injectors.
Codes 3581 and 3303 are not applicable in Massachusetts.
