Urea

AdBlue is 32.5% high-purity urea dissolved in 67.5% deionised water. To make it, you need automotive-grade (technical) urea, not fertilizer urea. Fertilizer grades can contain too much biuret and formaldehyde-based anti-caking agents, which take the fluid out of the ISO 22241 specification and can damage a vehicle’s SCR catalyst. This page is for AdBlue blenders,

Urea reduces vehicle emissions by turning harmful nitrogen oxides (NOx) into harmless nitrogen and water. It does this as AdBlue, also called diesel exhaust fluid (DEF): a solution of 32.5% high-purity urea in deionised water. The fluid is sprayed into the exhaust of diesel vehicles fitted with selective catalytic reduction (SCR). Most people know urea

Cosmetic grade urea is high-purity urea made for skincare and personal-care products. It is the same molecule as fertilizer urea, CO(NH2)2, but produced and handled to much tighter purity and contamination limits. In creams and lotions it acts as a humectant, drawing water into the skin, and at higher levels as a keratolytic, softening thick,

Urea powder is the fine crystalline form of urea (carbamide, CO(NH2)2), a white, odourless and highly water-soluble compound containing about 46% nitrogen. The same molecule is sold in very different grades: fertilizer urea for crops, technical urea for resins and chemicals, high-purity urea for AdBlue/DEF, feed-grade urea for ruminants and pharmacopoeia grades for creams and

There is no single public price for technical grade urea. It is sold on contracts that follow the global urea market, plus a premium for higher purity, tighter specifications and separate handling. The best public reference is the World Bank urea benchmark, which averaged $407.50 per tonne in September 2026 (granular urea, FOB Middle East).

Technical grade urea is high-purity urea made for industrial use rather than for fertilizer. It is typically 99% urea or more, with tightly controlled biuret, moisture and impurities. Industries use it to make resins and adhesives, AdBlue, chemicals, textiles and many other products. The chemistry is the same as farm urea. The difference is control:

The best-known urea fertilizer producers include Yara, CF Industries, Nutrien, QAFCO and SABIC Agri-Nutrients globally, and IFFCO, KRIBHCO, NFL, RCF and Chambal Fertilisers in India. But here is the honest answer most guides skip: standard fertilizer urea is a commodity. Any urea that meets the specification, 46% nitrogen with low biuret and moisture, performs the

Liquid and granular urea supply the same nutrient: nitrogen. The difference is how it reaches the plant. Granular urea is spread on the soil and works through the roots over days or weeks. Liquid urea is urea dissolved in water, applied through irrigation or sprayed on leaves for a faster, smaller dose. Neither is better

Urea is the most widely used nitrogen fertilizer in agriculture. It contains 46% nitrogen, the nutrient that drives leaf and stem growth, so it is used on almost every major crop: rice, wheat, maize, sugarcane and vegetables. Whether you farm a few acres or manage a large estate, urea is probably part of your season.

Urea is made by reacting ammonia with carbon dioxide at high pressure and temperature. The two gases first form ammonium carbamate, which then loses water to become urea. Unreacted gases are stripped out and recycled, the urea solution is concentrated into molten urea, and the melt is formed into prills or granules. This guide explains
