Class Code: 4829

Per NCCI's Scopes Code Description:

Code 4829 applies to the manufacture products requiring a chemical conversion. Chemical conversion is any process in which the substances used in the manufacturing process undergo a molecular change in composition. Refer to Code 4828 for employers that compound, blend, mix, bottle, and package chemicals when those operations are not otherwise classified. Unlike Code 4829, Code 4828 is assigned to employers that do not manufacture any of the ingredients they compound, blend, mix, bottle, or package.

The following briefly describes those processes that are specifically referenced in Code 4829’s note:

   
1.    Alcoholysis as used above means the process of introducing one or more alcohol groups into a compound for purposes of chemical conversion.
2.    Alkylation as used above means the process of introducing one or more alkyl groups into a compound for purposes of chemical conversion.
3.    Amination as used above means the process of introducing one or more amine groups into a compound for purposes of chemical conversion.
4.    Calcination as used above means the process of heating materials to a high temperature but without fusing in order to effect changes in the material.
5.    Carboxylation as used above means a chemical conversion involving carboxyl or carbon dioxide to form a carboxylic acid.
6.    Distillation as used above means a process of driving gas or vapors from liquids or solids by heating and condensing liquid products. Distillation may be used for, but is not limited to, purification, fractionation, or the formation of new substances. Employers that perform distillation may also use fermenting processes. Distillation of asphalt, wood, spirituous liquor, and fruit juice are separately classified.
7.    Esterification as used above means the process of introducing one or more ester groups into a compound for purposes of chemical conversion.
8.    Halogenation as used above means the process of combining a halogen (chlorine, bromine, fluorine, iodine, astatine) with another substance to form a new compound.
9.    Nitration as used above means the process of combining a nitrate (NO2) with another substance to form a new compound. Some of the ways nitration is performed are treating a substance with a mixture of strong nitric and sulphuric acid; adding nitric acid and strong sulphuric acid; nitric acid, alone, may be added to the substance; and solutions of nitrous gas or sodium nitrate in acid solutions may be used.
10.    Oxidation as used above means the process of uniting or of causing a compound to unite with oxygen chemically. The use of powerful oxidizing agents is included in the scope of Code 4829. The use or manufacture of substances such as chlorates, perchlorates, permanganates, and peroxides liberate large quantities of oxygen and are included within the definition of oxygenation.
11.    Sulphonation as used above means the combination of sulfates or sulfides with another substance to form a new compound.

Certain Code 4829 operations are designated as “not otherwise classified” (NOC). These NOC operations apply to an employer’s operations only when no other classification more specifically describes the employer’s operations. The following is a representative list of operations somewhat related in nature to Code 4829 operations that are not assigned to Code 4829.
