Phosphorus Chemical Industry Chain: From Rocks to Fertilizers

I. Industry Overview

The phosphorus chemical industry is a strategic pillar of China's chemical sector, playing a critical role in both national food security and the rapidly expanding new energy industry. Centered on phosphate rock as its primary raw material, the industry produces a wide range of phosphorus-containing products through two main processing routes: the wet-process and thermal-process technologies. These products serve agriculture, industrial manufacturing, food and pharmaceuticals, electronics, semiconductors, energy storage, and many other sectors.

Today, China's phosphorus chemical industry is undergoing a significant transformation. While traditional agricultural demand for phosphate fertilizers continues to grow steadily, the rapid expansion of the new energy sector, particularly lithium iron phosphate (LFP) battery materials - is reshaping the industry. As a result, the sector is evolving from a fertilizer-focused industry into a dual-engine growth model driven by both agricultural demand and advanced energy materials.

The total market value of China's phosphorus chemical industry exceeded RMB 280 billion in 2024 and is projected to reach RMB 420 billion by 2030, representing a compound annual growth rate (CAGR) of approximately 6.5%.

The industry's product portfolio can be broadly divided into two major categories:

• Agricultural products, including phosphate fertilizers and phosphorus-based agrochemicals, which support global food production.

• Industrial products, including high-purity phosphates, electronic-grade phosphoric acid, and specialty phosphorus compounds that support advanced manufacturing and clean energy technologies.

II. The Complete Phosphorus Chemical Industry Chain

1. Upstream: Raw Materials and Energy

The upstream segment is built around phosphate rock, sulfur, sulfuric acid, and silica, supported by energy inputs such as electricity and coke. Production facilities typically include acid treatment systems, purification units, and specialized chemical processing equipment.

Phosphate Rock Resources

As a non-renewable strategic mineral resource, phosphate rock distribution is highly concentrated worldwide:

• Global phosphate rock reserves are estimated at approximately 74 billion tonnes.

• Morocco alone holds around 50 billion tonnes, accounting for approximately 67.6% of global reserves.

• China possesses roughly 3.8 billion tonnes, representing approximately 5.1% of global reserves and ranking second worldwide.

• More than 90% of China's phosphate resources are concentrated in four provinces:

  • Yunnan (36%)

  • Hubei (25%)

  • Sichuan (18%)

  • Guizhou (13%)

A significant supply-demand imbalance exists globally. Although China holds only about 5.1% of global reserves, it accounts for approximately 40.9% of global phosphate rock production, with annual mining volumes reaching around 90 million tonnes. In contrast, resource-rich countries such as Morocco and Saudi Arabia possess abundant reserves but comparatively lower production levels, with substantial capacity expansion underway.

Raw Material Cost Pressure

More than 70% of China's phosphate rock consumption is used for fertilizer production, while the remaining 30% supports higher-value sectors such as:

• Yellow phosphorus

• High-purity phosphates

• Battery precursor materials

• Specialty phosphorus chemicals

Recent surges in sulfur prices and disruptions in import supply chains have significantly increased upstream production costs, accelerating the industry's push toward technological upgrades and resource efficiency.

2. Midstream: Processing Technologies and Product Manufacturing

The midstream sector converts phosphate rock into phosphoric acid and yellow phosphorus, which serve as the primary intermediates for the entire phosphorus chemical value chain.

Two major processing routes dominate the industry:

(1) Wet-Process Phosphoric Acid (Mainstream Technology)

Wet-process phosphoric acid is produced by reacting phosphate rock with sulfuric acid.

Depending on the crystallization form of calcium sulfate, several process variations exist, including:

• Dihydrate process

• Hemihydrate process

Current industry structure in China:

• Approximately 85% of production capacity uses the mature and cost-effective dihydrate process.

• Around 15% employs advanced hemihydrate technology capable of producing higher-concentration phosphoric acid directly.

The primary challenge associated with wet-process production is the generation of phosphogypsum, a large-volume industrial by-product. Efficient utilization and treatment of phosphogypsum remain among the industry's most important environmental and sustainability priorities.

(2) Thermal-Process Phosphoric Acid

Thermal-process phosphoric acid is produced by smelting phosphate rock, coke, and silica at high temperatures to produce elemental phosphorus, followed by oxidation and hydration.

Key characteristics:

• High energy consumption

• Significant environmental constraints

• Higher production costs

• Superior product purity

Due to its economics, thermal-process phosphoric acid is increasingly reserved for specialty applications and high-end phosphorus chemicals.
