For farmers, importers, distributors, and agricultural businesses, choosing the right DAP product means evaluating nutrient content, granule quality, packaging, certification, delivery terms, and the current DAP fertilizer price. This guide explains what to look for when you buy Diammonium Phosphate fertilizer in bags, container https://hortamericas.com/ loads, or bulk quantities.

Diammonium Phosphate 18-46-0 Dap granular

Diammonium phosphate, commonly called DAP, is a concentrated phosphate fertilizer produced by reacting phosphoric acid with ammonia. Its chemical formula is (NH4)2HPO4(NH_4)_2HPO_4(NH4​)2​HPO4​. The resulting product is a granular fertilizer that dissolves in soil moisture and releases ammonium nitrogen and plant-available phosphate.

The “18-46-0” designation describes the guaranteed nutrient analysis:

• 18% total nitrogen, expressed as N.

• 46% available phosphate, expressed as P₂O₅.

• 0% potassium, expressed as K₂O.

In practical terms, 100 kilograms of DAP fertilizer 18% N 46% P₂O₅ contains approximately 18 kilograms of nitrogen and 46 kilograms of P₂O₅-equivalent phosphate. The product does not provide potassium, sulfur, calcium, or micronutrients unless it has been specially blended.

Granular DAP fertilizer is popular because the granules are easy to transport, store, spread, and combine with other compatible fertilizers. Commercial specifications commonly include a granule size of approximately 2–4 millimeters, low moisture, high water solubility, and a free-flowing appearance.

How DAP supports crops

Phosphorus plays an important role in early root development, energy transfer, flowering, seed formation, and crop maturity. Nitrogen supports leaf growth, plant vigor, and chlorophyll formation. Combining both nutrients in one granule helps place nitrogen and phosphorus near the developing root zone.

DAP phosphate fertilizer is often applied before planting or during planting. It may be broadcast and incorporated into the soil, placed in bands near—but not directly against—seed, or included in a fertilizer blend. Application rates should be based on soil-test results, crop requirements, local agronomic recommendations, and the nutrient analysis of other products being used.

Common agricultural applications

Agricultural DAP fertilizer is suitable for many cropping systems, including:

• Maize, wheat, rice, barley, and other cereals.

• Soybean, groundnut, cotton, and other field crops.

• Vegetables, fruits, flowers, and greenhouse crops.

• Sugarcane, tobacco, coffee, cocoa, and plantation crops.

• Pastures and forage production.

• Compound NPK fertilizer manufacturing.

• Starter fertilizer programs where nitrogen and phosphorus are both required.

DAP is especially useful where soil testing indicates a need for phosphorus. However, it should not automatically be used on every field. Applying phosphorus when soil levels are already adequate can increase costs and contribute to nutrient losses or environmental problems.

Buy DAP fertilizer

When you buy DAP fertilizer, begin by confirming the product’s guaranteed analysis and grade. A reliable supplier should provide a technical data sheet, certificate of analysis, safety data sheet, product photographs, packaging details, and information about the manufacturing source.

Important product checks include:

• Total nitrogen: 18% minimum or as specified in the contract.

• Available P₂O₅: 46% minimum or as specified.

• Moisture content.

• Granule size distribution.

• Water solubility.

• Bulk density.

• Appearance and color.

• Caking resistance.

• Country of origin.

• Batch number and production date.

DAP can appear in different colors, including gray, brown, tan, or off-white, depending on the raw materials and production process. Color alone does not establish fertilizer quality. Laboratory analysis and contract specifications are more reliable indicators.

Buyers should also confirm whether the quotation is based on EXW, FOB, CFR, CIF, or another delivery term. A low product price may not represent the lowest landed cost after freight, insurance, port fees, customs charges, inland transportation, inspection, and handling.

Buy Diammonium Phosphate fertilizer

Businesses that buy Diammonium Phosphate fertilizer for resale or farm distribution should select packaging according to the destination climate and supply chain. Standard options include 25-kilogram bags, 50-kilogram bags, jumbo bags, and loose bulk shipments.

Common packaging materials include woven polypropylene bags with polyethylene liners. These bags help reduce moisture exposure during transportation and storage. For humid regions, lined bags, palletization, container desiccants, and covered warehouses can help protect the product.

Before placing an order, ask the supplier about:

• Minimum order quantity.

• Available bag sizes.

• Private-label or custom printing.

• Container loading capacity.

• Loading port and estimated transit time.

• Payment terms.

• Inspection options.

• Certificate and documentation requirements.

• Claims procedure for damaged or off-specification goods.

A professional Diammonium Phosphate supplier should be able to explain how the product is tested and how quality is maintained from production through dispatch. Contact

DAP fertilizer supplier

A dependable DAP fertilizer supplier should offer consistent quality rather than relying only on a low quotation. Evaluate the supplier’s experience with international agricultural trade, production capacity, export documentation, and ability to meet repeat orders.

Useful questions include:

1. Is the supplier a manufacturer, authorized distributor, or trading company?

2. Can it provide recent certificates of analysis?

3. Does it have experience shipping to your destination country?

4. Can it supply the required packaging and labeling?

5. What quality standard is used for each batch?

6. How are moisture and granule size controlled?

7. What are the payment, inspection, and claims terms?

A supplier that answers these questions clearly is generally easier to manage than one that provides only a product name and price.

Diammonium Phosphate supplier

When comparing a Diammonium Phosphate supplier, consider both product quality and commercial reliability. The supplier should clearly distinguish fertilizer-grade DAP from technical, industrial, food, or feed grades. These grades may have different purity standards, documentation, and permitted uses.

For agricultural distribution, request a fertilizer-grade specification that identifies:

• Nutrient analysis.

• Moisture limit.

• Insoluble matter.

• Particle-size range.

• Water-soluble phosphate.

• Bulk density.

• Product appearance.

• Storage recommendations.

• Applicable national or international standards.

Do not market fertilizer-grade DAP for food, feed, or industrial applications unless the product has been manufactured and certified for that specific purpose.

DAP 18-46-0 supplier

A quality DAP 18-46-0 supplier should provide material with uniform granules and dependable nutrient distribution. Uniform granulation improves spreading accuracy and reduces separation when DAP is blended with other dry fertilizers.

If the product will be stored for several months, arrange regular inspections for caking, moisture ingress, and changes in flowability.

Granular DAP fertilizer supplier

A Granular DAP fertilizer supplier should be able to provide granules that spread evenly through standard fertilizer equipment. Uniform granule size is important because very fine particles can create dust, while oversized particles may spread unevenly or separate during blending.

Before ordering, request a sample or recent production data showing:

• Typical granule-size distribution.

• Dust percentage.

• Crushing strength.

• Moisture content.

• Bulk density.

• Solubility.

• Product color and physical condition.

Granular DAP fertilizer may be used alone or combined with products such as potash, urea, ammonium sulfate, or micronutrient fertilizers. Compatibility should be checked before blending, and blended products should not be stored longer than necessary if moisture absorption or caking is likely.

DAP fertilizer manufacturer

When selecting a DAP fertilizer manufacturer, investigate the producer’s raw-material sources, production process, quality-control laboratory, and manufacturing capacity. A direct manufacturer may offer better consistency and pricing for large orders, although a trading company may provide flexibility for smaller shipments.

Diammonium Phosphate exporter

When comparing a Diammonium Phosphate exporter, assess shipping experience, communication, documentation accuracy, and ability to coordinate inspection. Exporters should state the price basis clearly and identify whether the quotation includes freight, insurance, bagging, and port charges.

Avoid paying for an international fertilizer order without verifying the company, bank details, trade references, and documentation. For large transactions, independent inspection and secure payment structures can reduce commercial risk.

DAP fertilizer distributor

A DAP fertilizer distributor purchases product in wholesale quantities and supplies retailers, agricultural cooperatives, farms, and commercial growers. Distributors should maintain a dry warehouse and use stock rotation to minimize long-term storage.

Good distribution practices include:

• Keeping bags on pallets rather than directly on the floor.

• Protecting the warehouse from rain and condensation.

• Separating damaged bags for inspection.

• Keeping fertilizer away from food, animal feed, and incompatible chemicals.

• Using first-in, first-out inventory rotation.

• Recording batch numbers and delivery dates.

• Training workers to control dust and prevent contamination.

DAP fertilizer dealer

A DAP fertilizer dealer should help customers select the correct product and explain that DAP supplies nitrogen and phosphorus but no potassium. Dealers should not recommend application rates without considering the crop, soil test, local conditions, and other fertilizers in the program.

Retail labels should clearly show the 18-46-0 analysis, net weight, manufacturer or importer, batch information, safety guidance, and application instructions required by local law.

DAP fertilizer price

The DAP fertilizer price changes with phosphate-rock and ammonia costs, energy prices, production outages, freight rates, currency movements, import policies, and seasonal agricultural demand. A September 2026 market update reported an average DAP price of approximately $923 per ton, while other benchmarks and regions showed substantially different levels.

Because DAP prices vary by region and trade term, buyers should request a current quotation that states:

• Currency.

• Price per metric ton.

• Packaging basis.

• Minimum order quantity.

• Incoterm.

• Loading port.

• Delivery port.

• Whether a sample is required.

• Any import or labeling requirements.

Clear inquiries produce more accurate and comparable quotations.

Bulk Diammonium Phosphate fertilizer

Bulk Diammonium Phosphate fertilizer is best suited to operations that can receive, store, and distribute large quantities efficiently. It can support commercial crop production, fertilizer blending, government procurement, plantation agriculture, and regional distribution networks.

Before buying bulk material, calculate expected consumption, warehouse capacity, handling losses, and storage duration. Moisture protection is essential, particularly in tropical and coastal locations. Sealed packaging, covered storage, raised pallets, and prompt stock movement can help preserve granule quality.

DAP 18-46-0 fertilizer

DAP 18-46-0 fertilizer is a practical choice when a crop program requires a concentrated source of both ammonium nitrogen and phosphate. Its high nutrient concentration means fewer tons may be required compared with lower-analysis fertilizers, helping reduce transportation and handling requirements.

Nevertheless, DAP is not a complete fertilizer. Crops may also need potassium, sulfur, zinc, boron, magnesium, or other nutrients. Use soil testing and crop-specific recommendations to determine whether DAP should be applied alone or included in a balanced fertilizer program.

Agricultural DAP fertilizer

Agricultural DAP fertilizer remains a major input for farmers and fertilizer distributors because it is concentrated, widely traded, and compatible with many crop-nutrition programs. The best buying decision combines agronomic suitability with commercial due diligence.

For dependable sourcing, choose a supplier that can demonstrate:

• Correct 18-46-0 nutrient analysis.

• Uniform, free-flowing granules.

• Suitable moisture and particle-size specifications.

• Strong packaging.

• Reliable shipment capability.

• Complete export documentation.

• Transparent pricing.
