Ammonium Sulfate Products
Crystalline and granular ammonium sulfate supplied from China under the grade analysis 21-0-0-24S — a dual-nutrient nitrogen and sulfur product for agricultural, compound fertilizer and industrial use.
Grades we quote
Both crystalline and granular ammonium sulfate are supplied. Where a specific particle size, packaging or document requirement applies to your order, it is confirmed against the TDS and COA for the production lot before you commit.
Ammonium Sulfate
Ammonium sulfate (NH4)2SO4, 21-0-0-24S — a dual-nutrient nitrogen and sulfur fertilizer supplied from China in crystalline and granular form for agricultural, compound fertilizer and industrial applications.
Specifications & applications → GranularGranular Ammonium Sulfate
Granular ammonium sulfate from China — a coarse, free-flowing form of (NH4)2SO4 for bulk blending, compound fertilizer production and mechanical application.
Specifications & applications → Crystalline / standardCrystalline Ammonium Sulfate
Crystalline (standard) ammonium sulfate from China — fine white crystals of (NH4)2SO4 for agricultural use, compound fertilizer production and industrial processing.
Specifications & applications →Crystalline or granular — which do you need?
The chemistry is identical. The difference is physical form, and it decides whether your blend holds together and whether your spreader works properly.
| Characteristic | Crystalline / standard | Granular |
|---|---|---|
| Nominal analysis | 21-0-0-24S | 21-0-0-24S |
| Particle form | Fine white to off-white crystals, as produced | Coarser, more uniform granules |
| Dissolution | Dissolves quickly | Dissolves more slowly |
| Bulk blending | Not suited — segregates from coarse granules | Suited — the form blenders specify |
| Mechanical spreading | Prone to dust and uneven feed | Feeds and spreads predictably |
| Typical buyers | Straight fertilizer supply, compound fertilizer producers, industrial users, fertigation | Bulk blenders, NPK producers, distributors selling granular material |
| Particle size distribution | Confirmed per lot — see TDS / COA | Confirmed per lot, against your blend requirement |

Packaging formats quoted
25 kg bags
Standard small bags for distributors and retail-facing supply. Bag material, printing and palletisation are agreed per order.
50 kg bags
Larger bags for agricultural distribution and handling systems that work at 50 kg unit weights.
Jumbo bags (FIBC)
Typically used for industrial buyers and for container or bulk programmes where large unit weights reduce handling cost.
Bulk (in vessel)
Loose cargo for bulk vessel shipment, subject to vessel availability, loading port facilities and discharge requirements at destination.
Loading quantity: Loading quantity depends on packaging, container type and shipping requirements.

Specifying an ammonium sulfate order
A quotation you can act on needs six things. Send all six and you will normally avoid a clarification round.
- Product and grade — ammonium sulfate, and the analysis you require
- Physical form — granular or crystalline, stated explicitly
- Particle size — if you blend or use mechanical spreaders, give the range
- Packaging — 25 kg, 50 kg, jumbo bags or bulk
- Quantity — a trial container, or a programme with a monthly profile
- Destination port and trade term — FOB, CFR or CIF; tell us the basis you want to work on
If you also need a specific document set, a letter of credit or an unusual packaging configuration, raise it with the first enquiry. See Ammonium Sulfate Specification Guide.
