Urea Fertilizer: What Buyers Should Know
Urea is a high-analysis nitrogen fertilizer containing 46% nitrogen, the most concentrated solid nitrogen source for field crops, rice, wheat, and corn. Buyers source urea from China for competitive bulk pricing, consistent granule quality, and large export volumes.
The key specifications are nitrogen content, biuret level, granule size, and moisture. Lower biuret is critical for foliar and fertigation use. The curated suppliers below are screened against these criteria.

7 Checks Before Choosing a Urea Fertilizer Supplier
1. Nitrogen content
Verify 46% minimum nitrogen on a dry basis.
2. Biuret level
Keep biuret below 1.0% for soil use and under 0.5% for foliar spraying.
3. Granule size
Uniform 2-4mm granules improve spreading accuracy and reduce segregation.
4. Moisture
Low moisture (below 0.5%) prevents caking during storage and ocean shipping.
5. Anti-caking treatment
Confirm the formaldehyde or coating level for long-distance transport.
6. Packaging
50kg bags, jumbo bags, or bulk; confirm your port handling capacity.
7. Compliance
Check destination import permits and fertilizer registration requirements.
Frequently Asked Questions
What is the nitrogen content of urea?
Standard agricultural urea contains 46% nitrogen, making it the most concentrated solid nitrogen fertilizer.
What is biuret and why does it matter?
Biuret is a by-product of urea production that can burn leaves; low-biuret urea is required for foliar and fertigation use.
Prilled or granular urea: which is better?
Granular urea is harder and spreads more uniformly, while prilled urea is finer and dissolves slightly faster.
What is the MOQ for urea from China?
Urea is usually traded in bulk or container loads, with MOQ around 25-50 metric tons depending on the supplier.
