Crystal carbamide (urea) is received from ammonia and carbon dioxide. carbamide is used in an

industry as raw materials at manufacturing of pitches, glues, etc., for use in agriculture as mineral

nitrogen fertilizer. Carbamide can be utilized in animal husbandry as fodder additive.

Depending on purpose, two carbamide marks are produced: A- for industry; B – for agriculture.

Carbamide is non-combustible, fire-and is explosion-proof under normal conditions. As regards to

its influence on organism, it falls into 3-rd class of hazardous substances. Carbamide is packed in

paper bitumized of laminated bags, polyethylene bags, woven polymeric laminated bags woven

polymeric bags with inserts, and also in soft specialized containers as MKR-1, OS. Carbamide is

stored in closed store rooms protecting the product from rainfall. At storage of product in bulk its

mixture with other fertilizers is not permitted. It is permitted to store carbamide containers and

transport packages fastened by synthetic film on open areas.

Warranty period of product storage – 2 years from the date of manufacturing.
