GUS classification
1) A classification of products into three categories for the benefit of goods flow control and stock control, based on a product’s area of application within a product division. G = General products that may be required in several main article groups or operations centres and are administered centrally in the division. U = Unique products that are used uniquely in one main article group or operations centre but in several of its products, and administered locally in the division. S = Specific products that are used exclusively in one higher-level product, and whose procurement is effected per individual order. (Source: ILT Supply-Chain Inventory Management SIG)
