Urea is the world's most widely traded nitrogen fertilizer — a white, crystalline solid carrying about 46% nitrogen, the highest of any common solid fertilizer, and also a feedstock for resins, AdBlue and industrial chemistry. That concentration makes it efficient to ship, but it also makes buying it a matter of precision: the right form, verified to the right specification, in packaging your site can actually handle. Urea has been one of 2026's most volatile commodities, so timing and supplier qualification matter as much as the headline price. This guide walks through both. Browse available grades on our Petrochemicals catalogue, part of our Industrial Products & Trading sector.
The short version
Pick your form by application: granular for bulk blending and mechanical spreading, prilled for liquid blends and industrial use. Specify to N46 with total nitrogen 46% min, biuret 1.0% max and moisture 0.5% max, demand a recent certificate of analysis, and lock in packaging and loading dates early — the market has swung by hundreds of dollars a tonne in 2026.
Step 1 — Decide what the urea is for
Most traded urea is fertilizer grade for broadacre and horticultural crops, but the same molecule also serves technical and industrial buyers: low-biuret grades for foliar feeding, and technical-grade urea for resins, melamine, cattle-feed and diesel-exhaust fluid (AdBlue/DEF). End use drives the specification — a foliar buyer cares most about biuret, a bulk-blend buyer about particle hardness and size, an industrial buyer about purity. Define the application before you talk grade.
Step 2 — Understand prilled vs granular
Urea is sold in two physical forms. Prilled urea is made by spraying molten urea down a prilling tower, giving small, near-spherical prills of roughly 1–3 mm that dissolve fast — the preferred choice for liquid fertilizer solutions and many industrial applications. Granular urea is built up into larger, harder particles that resist moisture and abrasion, so it holds up better in bulk blending with other nutrients and in modern mechanical spreaders. Most new commercial plants produce granules for their superior physical quality; prills remain widely traded where fast dissolution or smaller particle size is wanted. Both normally carry 46% nitrogen, so the decision is about handling, not nutrient value.
Step 3 — Check the specifications that matter
Whichever form you buy, a short list of parameters decides field and industrial performance: total nitrogen, urea purity, biuret, moisture and particle size. The table below sets out the values most commonly written into an N46 export specification. Always confirm exact limits against the supplier's certificate and your own agronomic or process requirement.
| Parameter | Typical N46 spec | Why it matters |
|---|---|---|
| Total nitrogen | 46% min | The nutrient you are paying for; sets application rate |
| Urea purity | 99% min | Confirms product identity and limits impurities |
| Biuret | 1.0% max (<1.5%) | High levels scorch leaves and hurt germination |
| Moisture | 0.5% max | Excess moisture causes caking and handling loss |
| Particle size | 1–3 mm (prilled); 2–4 mm (granular) | Drives spreader accuracy and blend compatibility |
A common pitfall is buying on nitrogen content alone. Two cargoes can both meet 46% N yet differ sharply in biuret, moisture or particle hardness — exactly the properties that cause caking in the warehouse or crop damage in the field. Our laboratory teams cross-check certificate values against the named specification before release; see how in Quality Assurance.
Step 4 — Verify before you ship
- Request a recent certificate of analysis covering total nitrogen, urea purity, biuret, moisture and particle size — tied to a named specification, not a generic brochure.
- Confirm the form and grade by name. State whether you need prilled or granular, fertilizer or technical grade, and any low-biuret requirement for foliar use.
- Pin down origin and consistency. Major supply comes from the Middle East, China, North Africa, Russia and Southeast Asia; source and plant vintage affect biuret and particle quality lot to lot.
- Match packaging to your site. Confirm whether you can discharge bulk or need 50 kg or jumbo bags, and specify anti-caking treatment and moisture-barrier liners where humidity is a risk.
- Use independent pre-shipment inspection at load port for larger contracts, and retain witness samples for dispute resolution.

Step 5 — Choose the right packaging
Packaging is a sourcing decision, not an afterthought — it dictates handling cost, moisture protection and how the product is discharged. The main options are 50 kg polypropylene bags (easy to distribute and retail, but higher unit cost), jumbo / FIBC bags of roughly 500 kg to 1 tonne (efficient for mechanised handling and bulk blenders), and bulk in vessel holds for large tenders (lowest unit cost, but needs silo or covered warehouse capacity at destination). Because urea is hygroscopic, confirm liner quality and anti-caking treatment against the humidity at your destination, and fix the format on the contract.
Step 6 — Manage price and supply risk
Urea has been a textbook case of geopolitical risk in 2026. After trading roughly in the US$350–450 per tonne band, granular prices spiked above US$700 per tonne in April as disruption around the Strait of Hormuz — through which a large share of seaborne urea passes — tightened supply, with Qatar reported to have suspended output. Prices have since retreated sharply: benchmark urea was quoted around US$368 per tonne at the end of June, down roughly a fifth over the month, and India's state importer NFL drew tender bids near US$445–449 per tonne CFR as Chinese export volumes returned under a managed June–August quota. Several analysts expect further downward pressure into the third quarter. The practical takeaways: qualify at least two origins, avoid buying into a policy-driven spike, and fix packaging and loading dates early given freight volatility.

Frequently asked questions
What is the difference between prilled and granular urea?
Prilled urea is formed by spraying molten urea down a tower, producing small, near-spherical prills of roughly 1–3 mm that dissolve quickly, which suits liquid fertilizer blends and many industrial uses. Granular urea is built up in larger, harder particles that resist moisture and handling damage, making it better for bulk blending and mechanical spreading over large areas. Both typically carry 46% nitrogen; the choice is driven by application, storage and spreading method rather than nutrient content.
How much nitrogen does urea contain?
Fertilizer-grade urea is rated 46-0-0, meaning about 46% nitrogen by weight, the highest of any common solid nitrogen fertilizer. Technical specifications usually state total nitrogen at 46% minimum and urea purity at 99% minimum. The high concentration lowers freight and storage cost per unit of nitrogen but makes correct handling and application timing important to limit volatilisation losses.
Why does biuret content matter in urea?
Biuret forms when urea is overheated during production and can be toxic to plants at high levels, causing poor germination and leaf scorch, especially in foliar sprays and sensitive crops. Fertilizer-grade urea is normally specified at 1.0% biuret maximum and kept below about 1.5%, while low-biuret grades below 1.0% are preferred for foliar and horticultural use. Always confirm the biuret limit on the batch certificate.
How is urea packaged for export?
Common formats are 50 kg polypropylene bags, jumbo or FIBC bags of about 500 kg to 1 tonne, and bulk in vessel holds for large tenders. Bagged product suits distribution and retail handling, while bulk lowers unit cost for buyers with silo or warehouse capacity at destination. The right format depends on volume, humidity at destination and how the product will be handled on arrival.
What documents should I request from a urea supplier?
Request a recent batch certificate of analysis showing total nitrogen, urea purity, biuret, moisture and particle size against a named specification, plus origin, form (prilled or granular) and packaging details. For larger contracts, independent pre-shipment inspection with SGS-style sampling and retained witness samples is good practice, along with confirmation of loading dates given current freight and export-policy volatility.
