Picking the right Calcium Ammonium Nitrate supplier in China isn’t just about comparing prices — it's a bit more involved. You really want to look at how consistent the product is. Things like checking the declared levels of nitrogen and calcium, the size of the granules, moisture content, and packaging details matter a lot before you place your order. Having a clear specs sheet can make comparing these factors way easier. Also, don’t hesitate to ask the supplier for recent batch test results and find out how they collect and test their samples. Little things, like whether a 25-kg bag arrives sealed, well-labeled, and free from clumps, can make a big difference too.
A dependable supplier should be willing to answer your technical questions straightforwardly and provide documents that match what they’re selling. It’s good to check their production capacity, lead times, experience with export orders, and how they handle quality issues. These details help you tell apart a manufacturer from a trading company, though honestly, either might work depending on what you need. Just don’t rely on fancy marketing claims alone — always verify with samples, records, and clear, written info.
One thing to keep in mind is that publicly available supplier profiles don’t always guarantee long-term consistency — even thorough checks can’t eliminate all risk. This guide walks you through practical ways to select the right supplier and points out what you can verify before asking for a quote. Ultimately, the so-called "best" option depends on your specific needs like grade, order size, delivery timeline, and quality standards. There's no one-size-fits-all answer here, so take the time to figure out what works best for you.
What Is Calcium Ammonium Nitrate? Typical 26% and 27% Nitrogen Grades
Calcium Ammonium Nitrate (CAN)is a granular Nitrogen Fertilizer that combines ammonium and nitrate nitrogen. Many formulations also include limestone or dolomitic material, which supplies calcium-bearing components. Typical commercial grades contain26% or 27% total nitrogen, though calcium content and nitrogen-form proportions can vary by specification. Details matter.
At equal tonnage, a 27% grade delivers more nitrogen than a 26% grade. That small difference can affect application calculations across a large field. Use the product label and local soil or crop guidance; do not infer calcium content from nitrogen percentage alone. Granules should be reasonably uniform, with limited dust and few damaged pieces. Appearance cannot confirm nutrient analysis.
When comparing suppliers, request a current specification sheet showing total nitrogen, nitrate and ammonium proportions, calcium analysis, granule size, and moisture limits. Ask how batches are tested, and check that delivered material matches the agreed specification. Store bags dry and sealed, since moisture can cause caking and uneven spreading. This detail is easy to overlook.
How CAN Is Made: Ammonium Nitrate Combined with Limestone or Dolomite
Calcium ammonium nitrate (CAN) is made by combining ammonium nitrate with finely ground limestone or dolomite. The ammonium nitrate is produced by reacting ammonia with nitric acid, then concentrated and formed into granules. The carbonate mineral is blended in to create a stable, free-flowing product and reduce its nitrogen concentration. Fertilizers Europe’s product information identifies 27% nitrogen as a common CAN grade, with nitrogen supplied in both ammonium and nitrate forms. These forms behave differently in soil, so crop needs and local conditions matter.
During production, consistent mineral particle size and thorough mixing help prevent uneven nutrient distribution. Granules are cooled, screened, and checked for size and moisture before storage. Small details count. Excess moisture can encourage caking; poor mixing may leave some granules richer in nitrogen than others. Dolomite also supplies magnesium, while limestone mainly contributes calcium carbonate. Calcium Nitrate is a different fertilizer, despite the similar name, and should not be confused with CAN.
Tips: Ask suppliers for a recent product analysis, including nitrogen content, particle-size range, and moisture. Check that bags stay dry and granules remain free-flowing. A specification sheet helps, but field performance can still vary with soil and weather.
Who Is the Best Calcium Ammonium Nitrate Supplier in China? - How CAN Is Made: Ammonium Nitrate Combined with Limestone or Dolomite
| Category | Dimension | Established Product or Process Information | What Buyers Should Verify |
| Product composition | Nitrogen content | Commercial CAN grades commonly contain about 26–27% total nitrogen. The exact grade and nitrogen guarantee vary by product. | Check the product specification and independent laboratory analysis for total nitrogen and the declared nitrogen forms. |
| Mineral component | Limestone | Limestone is primarily calcium carbonate (CaCO3). It can supply calcium and act as a mineral component in CAN formulations. | Request the declared calcium content, mineral analysis, and confirmation that the material meets the agreed specification. |
| Mineral component | Dolomite | Dolomite is a calcium-magnesium carbonate mineral, commonly represented by the formula CaMg(CO3)2. Its use can contribute both calcium and magnesium. | Check whether the formulation uses limestone, dolomite, or a blend, and verify the declared calcium and magnesium levels. |
| Manufacturing | Typical production concept | CAN is made by combining ammonium nitrate with a carbonate mineral component. Industrial production may use granulation or other controlled solid-forming processes. | Ask for a process description, product specification, and evidence that the stated process is appropriate for the supplied grade. |
| Manufacturing | Granule or prill form | CAN is commonly supplied as solid granules or prills. Particle-size distribution and physical properties depend on the product and manufacturing process. | Confirm the agreed particle-size range, appearance, and physical-quality limits in the purchase specification. |
| Quality control | Batch testing | Fertilizer quality is assessed against declared product specifications; relevant checks may include nutrient content, moisture, and physical properties. | Request a batch-specific certificate of analysis and confirm which test methods and acceptance limits are used. |
| Storage and handling | Moisture protection | Moisture can affect the handling and physical condition of fertilizer granules. Storage requirements depend on the product and packaging. | Review packaging, sealing, storage guidance, and shipment protection for the intended route and climate. |
| Supplier assessment | Traceability and documentation | A reliable supply arrangement should identify the product grade and batch and provide consistent technical and shipping documentation. | Evaluate batch traceability, certificates of analysis, safety documentation, export records, and the supplier’s ability to meet the contract specification. |
| Supplier assessment | How to compare suppliers | There is no single universally applicable “best” supplier; suitability depends on product compliance, verified quality, delivery capability, and the buyer’s requirements. | Compare documented test results, specification consistency, logistics, communication, and contractual terms rather than relying on an unverified ranking. |
How to Compare Suppliers: Nitrogen Content, Granule Size, and Moisture
When comparing a Chinese calcium ammonium nitrate supplier, request a recent, batch-specific certificate of analysis. Check total nitrogen and the nitrate and ammonium fractions separately; a “27% N” label alone tells only part of the story. CAN grades vary, so compare each result with the product specification in your purchase contract. The International Fertilizer Association’s 2024 Medium-Term Fertilizer Outlook places global nitrogen nutrient use around 110 million tonnes annually. That scale makes consistent batch records important, not just an attractive quotation.
Granules matter at the point of use. Ask for the size range and the percentage within it, rather than accepting “uniform granules.” A 2–4 mm range can serve as a useful comparison example, but it is not a universal grade requirement. Request sieve-analysis results and check for excess fines or oversized pieces; both can affect spreading consistency. Look closely at moisture, too. Ask for the measured value, test date, and agreed maximum, since damp granules may cake during storage. Small detail. A clear method matters.
Compare samples from more than one production batch, and retain sealed samples for an independent laboratory check if results are disputed. Verify that the paperwork identifies the same grade and batch as the shipment. Calcium And Nitrate content should be confirmed by analysis, not inferred from product name or appearance. Supplier documents can still be imperfect; that is a reason to specify test methods and acceptance limits before ordering, not to assume every certificate is unreliable.
How to Verify a 26% CAN Grade: 13% Nitrate-N and 13% Ammonium-N
A reliable Chinese CAN supplier should document more than “26% total nitrogen.” For a 26% grade, the declared split is 13% nitrate-nitrogen and 13% ammonium-nitrogen. Check that the certificate reports both forms on the same basis, usually product weight, rather than confusing nitrate ion with nitrate-nitrogen. That distinction matters.
Request a batch-specific certificate of analysis, production date, and sampling method. Then compare the paperwork with a representative, sealed sample. A qualified laboratory can measure total nitrogen and the nitrate and ammonium fractions independently. Ask for test methods and measurement uncertainty, not just rounded figures. If results sit near specification limits, repeat the sampling before accepting the lot. Granules can segregate during transport. A scoop from the top may mislead.
Check moisture and particle-size distribution too, since damp or uneven granules can affect handling and application. Visual checks are useful, but they cannot confirm nitrogen chemistry. I would not treat a polished certificate as proof by itself; documents and test results should agree. A supplier willing to explain discrepancies, retain samples, and support independent testing offers stronger evidence than a low price alone.
Which Quality Checks Matter: Batch Certificates, Sampling, and Lab Tests

Which Quality Checks Matter: Batch Certificates, Sampling, and Lab Tests
A dependable supplier should provide a batch certificate that matches the goods being shipped. Check the batch number, production date, declared nitrogen and calcium levels, moisture, and test methods. Confirm that units and product specifications are clear. A certificate is useful, but it is not independent proof; ask how the sample was collected and tested. Even neat paperwork can miss a real-world mismatch.
Tips: Compare the certificate with your purchase specification before dispatch. Request a sealed sample from the actual batch, not a display sample. For larger orders, arrange independent laboratory testing using agreed methods. Keep the sample label, seal number, and results together. Small details matter.
Lab results should identify the tested material and report measured values, methods, and any relevant uncertainty. Check physical properties, such as granule size and moisture, against the agreed specification. If a document refers to Water Soluble Calcium Nitrate, verify that it applies to that product; it is not a substitute for a calcium ammonium nitrate certificate. Ask the supplier to explain any gap between its certificate and your test results. Sampling can still be imperfect, so record how it was done and review the process when results differ.
Calcium Ammonium Nitrate: Essential Quality Checks
The bars count practical checklist items: 4 for batch certificates, 3 for sampling, and 5 for laboratory testing. They are checklist counts, not supplier-performance data. Confirm acceptance limits against the applicable product standard and purchase contract.
How to Rank Chinese Suppliers by Compliance, Export Capacity, and Reliability
Choosing the best calcium ammonium nitrate supplier in China requires more than comparing quoted prices. Start by checking whether product specifications match your intended grade, including nitrogen content, moisture limits, granule size, and packaging details. Request a recent certificate of analysis, safety data sheet, and batch traceability records. Paperwork matters. Confirm that documents match the actual product and shipment, not merely a sample file. Check whether the supplier can explain its quality-control process clearly and respond to technical questions without vague promises.
Next, assess export capacity through verifiable shipment records, realistic production schedules, and experience preparing destination-specific documents. Ask for a sample packing list and clarify who handles inspections, port coordination, and shipment updates. Reliability often shows in small details: consistent lot numbers, sealed bags, and prompt notice when a loading date changes. Compare references carefully, since one successful shipment does not prove consistent performance. Keep product records separate if your procurement also includes Soluble Calcium Nitrate; similar names do not mean identical specifications. A simple scorecard for compliance, capacity, communication, and delivery history can make supplier comparisons more objective, though document checks still need human judgment.
Calcium Sulphate Grey Granules: A Practical Soil Conditioner for Healthier Soil
Calcium sulphate grey granules offer a practical way to support healthier soil and more reliable crop growth. Made from natural gypsum and refined for consistent use, they provide calcium and sulphur while helping improve the condition of over-acidic soils when applied according to a soil test. By supporting a more balanced growing environment, the granules can encourage beneficial microbial activity and help crops establish strong roots.
In saline-alkali soils, calcium can help displace sodium, reducing its harmful effects and supporting better root development. The conditioner also helps soil particles form stable aggregates, which can ease compaction and improve air movement, water penetration, and moisture retention. Its nutrients are released gradually, providing steady support over time. Application is straightforward: spread the granules evenly across the soil or place them in furrows, following suitable rates for the crop and soil conditions. They can be used with a wide range of crops as part of a soil-management plan that supports productive farming and long-term soil health.

Conclusion
Calcium Ammonium Nitrate (CAN) is a nitrogen fertilizer commonly produced by combining ammonium nitrate with limestone or dolomite. Commercial grades often contain 26% or 27% total nitrogen, while a typical 26% grade provides approximately 13% nitrate-nitrogen and 13% ammonium-nitrogen. These forms supply nitrogen with different release characteristics, and the mineral component contributes calcium or magnesium depending on the raw material used.
When comparing Chinese suppliers, buyers should assess nitrogen content, granule size, moisture, and consistency between batches. Request current batch certificates, confirm that sampling is representative, and use independent laboratory testing when verification is needed. A reliable supplier should provide clear product specifications, maintain consistent quality controls, demonstrate suitable export capacity, and communicate transparently about documentation and delivery. Evaluating these factors together offers a practical basis for identifying a dependable supplier rather than relying on price or advertised claims alone.
