Class Code: 4484

Per NCCI's Scopes Code Description:

Code 4484 is applied to insureds that manufacture molded plastic products provided that the manufacture of the plastic product is not otherwise classified. The manufacturing process will require the use of low- or high-pressure devices and may involve compression or injection molding. Raw materials used may be in the form of pellets, granules, powders and liquid dispersions.

Compression molding involves the placement of raw materials directly into a mold cavity and subjecting the material to a variable hydraulic pressure. The pressure is dependent upon the type of raw material and the article being molded.

Injection molding involves loading the raw material into a hopper which feeds into a cylinder. The raw material is then forced by a hydraulic ram into a heating chamber under pressure. After being plasticized, the material is forced into a cold mold to solidify the article. After solidification, the article is ejected from the mold.

The classification includes die making and all subsequent machining, finishing, assembling and forming operations necessary to complete the molded products.

Code 4484 also is applied to insureds engaged in the laminating of plastic products by use of heat and pressure. Layers of cloth or paper are impregnated with liquid plastic, dried, cut to size, stacked and inserted into a laminating press. Heat is applied and steel sheets within the press impart a finish similar to the finish in compression molding. After removal from the press, the laminated material may be machined, buffed or polished.

The manufacture or assembly of plastic dolls or doll parts is assigned to Code 4484. The manufacture of nonplastic parts, doll clothing or the dressing of the dolls is separately classified.

Examples of the manufacture of fiberglass or plastic products assigned to Code 4484 include bottles, chair frames, cleats, doors, dune buggy bodies, fish tanks, satellite dishes, swimming or wading pools and tubs (bath or hot).

Code 4484 contemplates insureds that manufacture various plastic products using a brush to place or gun to spray layers of fiberglass and fillers over or into molds or forms. Once the desired thickness has been attained, the material is left to set for a period of time and then is removed from the mold.

Insureds engaged in metal parts manufacturing from powdered metals, and insureds engaged in laminating liquid plastic impregnated fibers by use of brush or spray, either in or over a mold or form, are assigned by analogy to Code 4484, provided the products being produced are not otherwise classified.

Code 4484 is also applied to insureds engaged in the manufacture of all types of buttons made from raw materials such as sheets or rods of plastic, glass or other synthetics, mussel or clam shells, vegetable ivory and wood blocks. The manufacture of buttons from metal or exclusively from fabric is separately classified. The raw material is automatically sliced into blanks or discs. The blanks are classified and churned to remove rough edges. Some blanks are soaked to soften while others may be soaked to harden. The blanks are then dried and machined into various shapes and patterns. The eyes are drilled and the buttons are tumbled, polished and inspected. They are then sorted into various grades and counted. Some are boxed while others are sewn onto cards by machine and packaged.

It is important to reiterate that Codes 4452 or 4484 are applicable only when products being manufactured are specifically referenced in these scopes or the manufacture of a plastic product cannot be assigned to another classification either by specific reference or by analogy. In prioritizing classification procedures for manufacturers of plastic products, the classifier should first determine if a specific product manufacturing class is applicable to the operation. An example of a product class is Gear Mfg. In the event one does not find a specific product class, an industry class such as Sporting Goods Mfg. should be considered. In the event a product or industry class does not specifically describe the product being manufactured, or the product being manufactured cannot be assigned by analogy to either the industry or product group, either Codes 4452 or 4484, the “not otherwise classified” plastics manufacturing codes, should be assigned to the manufacture of a plastic product.

Certain Code 4484 operations are designated as “not otherwise classified” (NOC). These NOC operations shall apply to an insured only when no other classification more specifically describes the insured’s operations. In addition to the above references, the following is a representative list of operations somewhat related in nature to Code 4484 operations that are not assigned to Code 4484:

2688 Leather Goods Mfg. NOC    
9501 Painting—Shop (Plastic Sign Mfg.—Computerized)    
4273 Plastic Bag Manufacturing    
4452 Plastics Mfg.—Fabricated Products NOC    
4459 Plastics Mfg.—Sheets, Rods, Tubes    
4299 Printing (Plastic Sign Mfg.—Computerized)    
2683 Vinyl Bag Mfg.    
2670 Vinyl Glove Mfg.    
2660 Vinyl Shoe Mfg.    

In addition to this representative list, one should review sources such as the alphabetical index in this manual to determine whether a classification other than Code 4484 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 2501 for the manufacture of vinyl gloves (Code 2670 is N/A MA).
