Urea — Granular, Grade B (Highest Grade & 1st Grade, GOST 2081-2010)
Specification
| Characteristic | Highest Grade | 1st Grade |
|---|---|---|
| Mass fraction of nitrogen, dry matter | ≥ 46.2% | ≥ 46.2% |
| Mass fraction of biuret | ≤ 1.4% | ≤ 1.4% |
| Mass fraction of water (hygroscopic) | ≤ 0.3% | ≤ 0.3% |
| Mass fraction of water (total) | ≤ 0.6% | ≤ 0.6% |
| Crumbly | 100% | 100% |
| Granulometric composition | ||
| Granules 1–4 mm | ≥ 94% | ≥ 94% |
| Granules 2–4 mm | ≥ 70% | ≥ 50% |
| Granules < 1 mm | ≤ 3% | ≤ 5% |
| Residue on 6 mm sieve | absent | absent |
| Static strength per granule | ≥ 7 N (0.7 kgf) | ≥ 5 N (0.5 kgf) |
Standards: GOST 2081-2010 (origin), KS 1900-1:2011 (Kenyan import standard). Sampling per KS 158:2018.
The Grade B specification is the premium granulometric standard. The higher static strength (≥ 7 N for Highest Grade) and tighter 2–4 mm fraction (≥ 70%) reduce dust generation in handling, improve broadcasting precision in mechanised application, and minimise caking under coastal humidity. Premium over Grade A: typically $5–15 per MT FOB.

Payment
Buyer's bank issues; seller's bank advises or — where required — confirms. Sarpah is not on the instrument chain.

Application
Grade B urea is preferred for mechanised broadcasting at scale — large estate farms, NCPB depot distribution, KTDA tea operations where precision and minimal dust matter. The higher granule strength survives augers, conveyors and pneumatic conveying systems with minimal degradation.
For subsidy-channel distribution (KNTC → NCPB depots → smallholder voucher), Grade A is typically sufficient. For private-channel sales to large estates, blenders and KEBS Diamond Mark-licensed handlers, Grade B commands the premium.
