Ammonium sulfate grades supplied from China
We supply ammonium sulfate as a straight fertilizer product and as an input for compound fertilizer production and industrial processing. Both crystalline and granular forms are supplied. Every order is specified individually — the particle size, analysis and packaging applying to your shipment are confirmed against the TDS and COA for the production lot.
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.

All products →Why source ammonium sulfate from China?
China is one of the world's largest production and export bases for ammonium sulfate. For international buyers, working through a China-based export team means access to that supply base without having to establish a presence in it.
- A large supply base. Ammonium sulfate comes from more than one type of production process in China. Working with a supplier who can access several sources makes it easier to match a grade to your application and to keep a programme running when one source is unavailable.
- Export experience. Chinese ammonium sulfate moves to agricultural and industrial buyers worldwide as a routine export commodity, with established shipping routes from the main ports.
- Documentation. A manufacturer's certificate of analysis for the lot shipped, a technical data sheet and the standard export document set are issued with each shipment.
- Packaging options. Bags to your specification, jumbo bags for industrial and large-volume buyers, and bulk cargo for vessel programmes.
- Container and bulk shipping. Bagged material ships in containers; large programmes can be arranged as bulk vessel cargo where the destination can discharge loose material.

Three ways ammonium sulfate is used
The chemistry is the same in every case. What changes is the specification a customer buys against — analysis, particle size and packaging all follow from the end use.
Agriculture
Straight nitrogen and sulfur fertilizer. Ammonium nitrogen with no volatilisation pathway, sulfur in the sulfate form plants take up directly, and an acidifying effect that is useful on alkaline soils.
Agriculture →Compound Fertilizer
A nitrogen and sulfur carrier for NPK production and bulk blending. For blenders, particle size distribution is the parameter that decides whether the blend holds its analysis.
Compound fertilizer →Industrial
Processes requiring a sulfate or ammonium source. Industrial buyers generally specify from the process requirement rather than from an agronomic grade — tell us the parameter that matters.
Industrial →Guides for ammonium sulfate buyers
Written for people placing orders rather than for search engines: how the import process works, how to write a specification, what packaging to choose and how to evaluate a supplier.

What is ammonium sulfate and what does 21-0-0-24S mean?
Ammonium sulfate is an inorganic salt with the formula (NH4)2SO4. The fertilizer grade is described by its analysis as 21-0-0-24S — approximately 21% nitrogen and 24% sulfur, with no phosphorus or potassium. The exact figures for a cargo are declared on the certificate of analysis for that production lot.
Do you supply granular as well as crystalline ammonium sulfate?
Yes — we supply both. Granular material is usually specified by blenders and compound fertilizer producers; crystalline material suits direct application, fertigation and industrial use. Tell us the form and destination and we will confirm the specification available for your shipment.
Can you export ammonium sulfate from China?
Yes — this website exists to serve international ammonium sulfate buyers. Export availability, documentation and inspection requirements are confirmed for each specific product, quantity and destination before you commit.
What packaging is available?
25 kg bags, 50 kg bags, jumbo bags (FIBC) and bulk cargo in vessel. Loading quantity depends on packaging, container type and shipping requirements, and is confirmed for your specific order.
Can you provide a COA and a TDS?
A technical data sheet is provided for the grade offered. A certificate of analysis is issued by the manufacturer for the specific production lot shipped. Additional certification is reviewed per order before contract.
More questions, including packaging, documents, MOQ and payment terms, are answered on the FAQ page.
Looking for ammonium sulfate from China?
Request product specifications and a quotation. Tell us the grade, form, quantity, packaging and destination port and our export team will confirm what is actually available for your programme.
