DAP Fertilizer (Diammonium Phosphate 18-46-0) Specification, Bulk Supply & Global Trade

Overview of DAP Fertilizer

DAP fertilizer, formally known as Diammonium Phosphate, is a high-analysis phosphate fertilizer widely used in modern agriculture and fertilizer manufacturing. Its standard nutrient grade 18-46-0 represents a carefully balanced composition of nitrogen and phosphorus designed to support early plant development and efficient nutrient uptake.

Due to its high phosphorus content and reliable agronomic performance, DAP fertilizer plays a strategic role in global food production systems. It is commonly applied in large-scale farming operations and is also used as a base material in the production of compound fertilizers.

Chemical Composition and Nutrient Characteristics

DAP fertilizer is produced through the controlled neutralization of phosphoric acid with ammonia, resulting in a stable ammonium phosphate compound.

Key nutrient characteristics:

• Nitrogen is present in ammonium form, offering controlled availability and reduced leaching compared to nitrate based fertilizers.

• Phosphorus is highly available, supporting root initiation, energy transfer, and early plant vigor.

• The product is mildly alkaline, which can temporarily influence soil pH around the granule.

This chemical structure makes DAP fertilizer particularly effective during the initial growth stages of crops when phosphorus demand is at its highest.

Agricultural Uses and Crop Applications

DAP fertilizer is primarily applied as a starter fertilizer, either banded near the seed or broadcast before planting.

Typical applications include:

• Cereal crops such as wheat, maize, rice, and barley

• Oilseed crops including soybean, sunflower, and canola

• Industrial crops such as sugar beet and cotton

• Orchard trees and perennial crops during early-season nutrient programs

• Raw material input for NPK fertilizer production and blending

DAP fertilizer is best suited for soils with low to moderate phosphorus levels. Proper soil testing is recommended to optimize application rates and avoid nutrient imbalance.

Packaging Formats and Supply Options

DAP fertilizer is supplied in multiple packaging configurations to meet diverse logistical and market requirements:

• Standard 50 kg polypropylene bags

• Jumbo bags (500 kg and 1,000 kg)

• Bulk shipment for large-volume agricultural and industrial buyers

Packaging selection depends on destination, handling infrastructure, and storage conditions. Private labeling and customized packaging can be arranged for export-oriented customers.

DAP Fertilizer Pricing Structure

DAP fertilizer price is influenced by a combination of raw material costs, global market conditions, and logistical factors.

Key pricing determinants include:

• Cost of phosphoric acid and ammonia

• Production origin and energy inputs

• Order quantity and packaging type

• Incoterms such as FOB, CIF, or CFR

• Freight rates and destination port

For these reasons, DAP fertilizer price per ton is typically quoted on request, based on current market conditions and buyer requirements. Long-term supply contracts and bulk volumes may benefit from more stable pricing structures.

Global Trade and Export Considerations

DAP fertilizer is actively traded in international markets and is a key import product for many agricultural economies.

Trade-related details:

• Common HS Code: 3105.30

• Shipped via containerized cargo or bulk vessels

• Suitable for long-distance international transport

Major importing regions include South Asia, Africa, the Middle East, and Latin America, where phosphorus demand remains structurally strong.

Quality Assurance and Documentation

To support international trade and regulatory compliance, DAP fertilizer shipments can be accompanied by:

• Certificate of Analysis (COA)

• Material Safety Data Sheet (MSDS)

• Third-party inspection reports (SGS or equivalent, if required)

Consistent quality control ensures uniform nutrient content, granule integrity, and safe handling throughout the supply chain.

Storage and Handling Guidelines

DAP fertilizer should be stored in dry, well-ventilated areas to prevent moisture absorption and caking. During transport and storage:

• Avoid prolonged exposure to high humidity

• Use clean handling equipment

• Follow MSDS guidelines for safe handling

Proper storage preserves product quality and ensures smooth application at the point of use.
