The core driving factors of the price surge are analyzed, and professional suggestions on specification selection, cost control and procurement planning are finally provided.

1. Definition of Mesh
Mesh is the core industry unit for measuring the particle size of granular materials, referring to the number of holes in the sieve screen per inch (2.54 cm) in length; the larger the mesh number, the finer the corresponding particle size and the smaller the sieve pore size.

- 8-30 Mesh: Coarser particles, low water flow resistance, high flux, suitable for high-flow continuous water purification scenarios, and is the mainstream choice for municipal water supply and small commercial water purification systems.
- 12-40 Mesh: Finer particles, larger specific surface area, higher adsorption efficiency, suitable for compact filter cartridge structure, and is the core filling specification for household water purifiers and water purification faucet filter cartridges.
II. Main Types and Applications of Activated Carbon for Water Treatment
Activated carbon products in the water treatment field are usually classified by morphology and raw material, and different categories have significant differences in applicable scenarios and core characteristics:
1. Classification by Morphology
- Powdered Activated Carbon (PAC): Particle size <0.18mm, fast adsorption speed, non-regenerable; mostly used in industrial wastewater pretreatment, emergency algae removal / odor removal scenarios, coal-based powdered carbon is the mainstream in the industry.
- Granular Activated Carbon (GAC): Particle size 0.4~2.4mm, regenerable, stable filtration and adsorption performance; it is the core category in the water treatment field, and the mainstream products include coal-based granular activated carbon and coconut shell granular activated carbon.
2. Classification by Raw Material and Scenario Adaptation
- Coal-based Granular Activated Carbon: Low cost, high mechanical strength, developed mesopore structure; it is the preferred category for municipal water supply systems and industrial wastewater advanced treatment, and the 8-30 mesh specification is the most widely used in the industry.
- Coconut Shell Granular Activated Carbon: Micropore accounts for 85%~95%, uniform pore size distribution, low ash content (≤5%), it is a recognized high-end preferred material in the drinking water purification field; the core application specifications are 8-30 mesh (small water purification systems) and 12-40 mesh (household water purification equipment).
- Other Fruit Shell Activated Carbon (Apricot Shell / Peach Shell): Lower mechanical hardness than coconut shell carbon, lower procurement cost; it is a cost-effective alternative in the water purification field, and cannot be used for gold extraction due to insufficient hardness, only suitable for water purification scenarios.
III. Core Role of Coconut Shell Activated Carbon in Water Treatment
Coconut shell activated carbon is the most popular activated carbon product in the current drinking water purification field, and its core value is concentrated in four dimensions:
- Heavy Metal Adsorption and Removal: With a uniform micropore structure, it efficiently adsorbs heavy metal ions such as iron, lead and chromium in water, greatly reducing the health risks of drinking water.
- Water Quality and Taste Optimization: Precisely adsorbs residual chlorine, odor, volatile organic compounds (VOCs) such as trihalomethanes (THMs) in water, removes discoloration, and significantly improves the purity and taste of drinking water.
- Water Quality Softening Regulation: Through the synergistic effect of ion exchange and physical adsorption, it reduces the content of calcium and magnesium ions in water, and effectively alleviates the problem of scale formation.
- Core Filter Material for High-end Water Purification: It is an essential core material for high-end household water purifiers, water purification faucets, and commercial pure water systems, and also the core raw material of UDF granular carbon filter cartridges and CTO compressed carbon filter cartridges.

Core Reasons for the Price Surge
Raw Material Side: Continuous Tight Supply of Coconut Shell99% of China's coconut shell raw materials are imported from Southeast Asia (mainly Philippines, Indonesia, Vietnam); frequent natural disasters in Southeast Asia from 2024 to 2025 led to a 30% reduction in coconut shell production, and the procurement price of raw materials continued to rise, pushing up product costs from the source.

Demand Side: Production Capacity of High Iodine Value Carbon is Occupied by the Gold Extraction Industry
- Coconut shell activated carbon with iodine value above 1000 and 6-12 mesh large particles is a special product for gold extraction (core raw material of Carbon-in-Pulp (CIP) / Heap Leaching), with explosive market demand and significant premium, and a large amount of production capacity is tilted to this category.
- The production capacity of 8-30 mesh / 12-40 mesh (below 1000 iodine value) water purification-specific specifications has been squeezed, the market is in short supply, and orders from activated carbon factories are generally backlogged, with a conventional delivery cycle of up to 1 month.
Logistics Side: New Sea Freight Regulations Significantly Increase Transportation CostsSince January 2026, coconut shell carbonized material has been classified as dangerous goods for transportation, which requires the use of special containers and special customs declaration procedures, directly leading to a 30%~40% increase in sea freight logistics costs, and further extending the delivery cycle at the same time.
Alternative Demand Drives Up Premium in ReverseAfter the price of coconut shell activated carbon skyrocketed, a large number of downstream water purification manufacturers turned to alternative products such as apricot shell / peach shell activated carbon. The procurement demand of alternative categories surged, and the price rose synchronously, which in turn pushed up the market premium of coconut shell activated carbon.

V. Summary and Selection Recommendations
-
Specification Selection: The 8-30 mesh specification is suitable for municipal water supply and small commercial water purification scenarios. It is preferred to choose products with 900~1000 iodine value, which can balance high flow flux and basic adsorption effect; the 12-40 mesh specification is suitable for household water purifiers and water purification faucet filter cartridges. It is preferred to choose products with 1000~1100 iodine value, which can ensure deep purification effect and water quality taste.
-
Cost Control: For water purification projects with limited budget, apricot shell / peach shell activated carbon can be used as a cost-effective alternative, which can meet the adsorption demand of conventional water purification scenarios, and the procurement cost is significantly lower than that of coconut shell activated carbon of the same specification.
-
Procurement Planning: The current coconut shell activated carbon market is in a stage of tight supply and demand and high price operation. It is recommended that customers with long-term procurement needs lock prices and stock up in advance with professional suppliers, or customize graded products to control comprehensive costs.
