Carbamide is used in industry as a raw material for manufacturing of resins, glues, in agriculture as a mineral nitric fertilizer and in cattle-breeding as a fodder additive.

Exported carbamide quality should meet requirements of a contract with a foreign buyer. Fraction of total nitrogen mass in recalculation to dry substance with norm no more than 46.0%, fraction of total biuret mass with norm no more than 3%, fraction of total free ammonia with norm no more than 0.03%, fraction of total water mass with norm no more than 0.3% (using drying method) are defined in carbamide for cattle-breeding. Fraction of total nitrogen mass in recalculation to dry substance with norm no less than 46.2%, fraction of total biuret mass with norm not more than 1.5%, fraction of total water mass with norm no more than 0.3% (using drying method) are defined in carbamide for retail. Indices for carbamide of first-rate grade a with appropriate norms are defined while shipping grade b carbamide according to demands of consumers in industry.
Carbamide is shipped in a packed state for retail with weight not more than 3 kg and in bulk by minerals' transporters.
6 months from a date of manufacturing, 2 years – for retail.
