DAP Fertilizer Market in October 2026: Prices Anchor Around $802/Ton, Market Stagnates Awaiting New Signals

The global fertilizer market entered October 2026 with a cautious sentiment as prices for phosphate-based fertilizers, particularly Diammonium Phosphate (DAP), continued a sideways trend while remaining at very high levels. In Vietnam, demand for the upcoming 2026 - 2027 Winter-Spring production season is beginning to pick up, placing pressure on the agricultural supply chain as import prices remain stable around the $800/ton threshold.

1. Overview of World and Vietnam DAP Fertilizer Prices in October 2026

Global fertilizer market data as of mid-October 2026 recorded DAP trading prices at $802.50/ton (equivalent to approximately 20,742,458 VND/ton). Compared to the slight adjustments at the beginning of the month, prices have seen a modest recovery of +$2.50/ton (+0.3125%) from the $800.00/ton mark established on October 7 and October 8, 2026.

In general, the fluctuation range over the past 30 days has been relatively narrow, ranging between $800.00 - $802.50/ton (approximately 20,677,840 - 20,742,458 VND/ton). The average price for October currently stands at $802.12/ton (approximately 20,732,636 VND/ton), nearly equivalent to the average for September 2026 ($802.50/ton). This clearly reflects a fierce tug-of-war between high production cost pressures and caution from global buyers.

In the domestic Vietnamese market, DAP fertilizer prices have remained relatively stable, following the global sideways trend:

• DAP Dinh Vu and DAP Lao Cai: Wholesale prices at the factory fluctuate around 17,500,000 - 18,200,000 VND/ton, depending on the delivery area and commercial discount policies.
• DAP imported from China (64% grade, yellow/brown): Retail prices in the Mekong Delta and Central Highlands range from 21,500,000 - 22,800,000 VND/ton.
• DAP imported from Russia, South Korea, and Jordan: Maintained in the premium segment with prices from 22,000,000 - 23,500,000 VND/ton.

2. Analysis of Reasons for DAP Prices Holding at Peak within a Narrow Range

The stability of DAP at high price levels in October 2026 is driven by several factors, including raw material supply chain dynamics and export regulatory policies:

Input Material Costs Remain High

DAP is primarily produced from phosphate rock, ammonia (NH3), and sulfuric acid (H2SO4 - produced from sulfur). In October 2026, the liquid and granular sulfur market recorded tight supply in the Middle East due to periodic refinery maintenance, pushing sulfur prices up slightly. Simultaneously, the price of natural gas – the primary feedstock for ammonia production – remains high ahead of the Northern Hemisphere winter, preventing fertilizer producers from lowering their offer prices.

Export Quota Management Policies of Major Countries

China – a leading producer and exporter of phosphate – continues to enforce strict export quota policies to prioritize domestic market stabilization and food security. The absence of large volumes of competitively priced DAP from China in the international free market has created a significant gap, forcing importers from India, Pakistan, and Southeast Asia to seek alternative sources from Morocco (OCP) or Saudi Arabia (Ma'aden) at higher prices.

Supply-Demand Balance in Key Markets

Demand in India – the world's largest DAP consumer – has slowed down as import prices exceed government subsidy levels; however, emergency tenders to secure the Rabi planting season continue to appear sporadically. In South America (particularly Brazil), demand for base fertilization for the soybean crop is mostly complete, but low inventory pressure at arrival ports has prevented a decline in prices for this commodity.

3. Impact of Macroeconomic Factors

DAP fertilizer fluctuations in October 2026 cannot be separated from complex macroeconomic movements in the international market:

• Geopolitics and Energy Markets: Geopolitical tensions along vital maritime shipping routes (Red Sea, Persian Gulf) continue to increase maritime insurance costs and freight rates. This directly adds $25 - $40 to every ton of fertilizer arriving at ports in Southeast Asia.
• USD/VND Exchange Rate Pressure: The DXY index maintains its strength in the face of cautious interest rate policies from major central banks. The high USD/VND exchange rate makes the conversion cost for importing raw materials and finished fertilizers into Vietnam expensive, increasing the financial burden for commercial importers.
• Tax and Environmental Policies: The trend of applying low-carbon emission standards and environmental taxes on heavy industry in Europe and North America has begun to create new compliance costs for chemical plants, indirectly raising the global production cost of phosphate fertilizers.

4. Impact on the Agricultural Sector and Vietnamese Enterprises

The high level of DAP prices throughout October 2026 has multi-dimensional impacts on domestic stakeholders:

For farmers: Fertilizer costs account for 20 - 30% of the total production cost of rice, fruit trees, and industrial crops. Maintaining DAP prices above 20 million VND/ton requires farmers to rebalance their cultivation processes, increase the use of organic and microbial fertilizers, or switch to high-tech NPK lines to optimize phosphorus absorption and avoid waste due to loss.

For domestic production enterprises: Entities that are self-sufficient in apatite ore, such as DAP Dinh Vu or DAP Lao Cai, have the opportunity to leverage the advantage of domestic prices being more competitive than imports. However, these enterprises also face the challenge of rising sulfur and ammonia raw material costs, requiring optimal inventory management and production line maintenance to protect net profit margins.

5. Trend Outlook and Recommendations for the End of 2026

Based on the stable trading price trend around $802.50/ton in the first half of October 2026, the DAP fertilizer market is expected to continue its accumulation phase, with little possibility of a deep downward adjustment between now and the end of November 2026. Support from winter energy costs and the demand for preparing for the Winter-Spring season in Vietnam will act as a solid foundation for fertilizer prices.

Recommendations for agents and distributors:

• Proactively monitor import progress and vessel schedules arriving at ports in the second half of October to avoid the risk of local shortages when entering the peak of the Winter-Spring sowing season.
• Avoid excessive speculative stockpiling while the price range is at a short-term peak; instead, adopt a staggered purchasing strategy to average out capital costs.
• Strengthen technical advice for farmers on balanced fertilization solutions, combining single and compound fertilizers to minimize direct cost pressures per hectare of cultivation.

In summary, October 2026 marks a consolidation phase for DAP prices on the international trade map. Businesses and farmers need to proactively adapt to the new price level by improving usage efficiency and remaining flexible in their agricultural supply business strategies.
