Starting April 1, 2026, China will cancel the VAT export tax rebate for certain organic phosphorus chemicals.
This policy mainly targets pesticide technicals but also includes inorganic phosphates like sodium hexametaphosphate and trisodium phosphate, which are raw materials for water treatment chemicals.
Consequently, production costs may rise for water treatment companies. Additionally, this change aligns with a global industry shift towards greener, more efficient specialty chemicals, encouraging innovation and supply chain optimization.
Which Products Are Affected?
We will now analyze the specific products impacted by the policy. Understanding this is crucial because it directly clarifies the scope of the change and helps your company identify potential risks and opportunities within the supply chain.
1. Directly Affected Product List
The new policy targets specific categories of products for export tax rebate cancellation. It’s important to distinguish between those directly listed and those potentially affected indirectly.
Pesticide-related Organic Phosphorus Products:
The policy explicitly cancels rebates for numerous pesticide technical materials and intermediates. Examples include glufosinate, dichlorvos, and acephate.
While these are primarily used in agriculture and have a lower direct relevance to water treatment, companies with diversified business operations spanning both agrochemicals and water treatment chemicals should be cautious of cross-over risks.
Inorganic Phosphate Raw Materials:


This is the category of highest direct relevance to the water treatment industry. Key raw materials used in water treatment chemicals, such as Sodium Hexametaphosphate and Sodium Tripolyphosphate, are explicitly listed in the policy for rebate cancellation.
These phosphates are fundamental ingredients in many scale and corrosion inhibitors. The cancellation will directly increase the production cost for manufacturers relying on these exported raw materials.
2. Key Difference: Raw Materials vs. Finished Preparations
A critical aspect of this policy is its focus on the early stages of the chemical supply chain. The rebate cancellation specifically applies to products classified under Chapter 29 of the Customs Tariff, which covers organic and inorganic chemicals, including raw materials and intermediates.
However, most finished water treatment chemical preparations (e.g., formulated scale inhibitors, corrosion inhibitors, biocides) typically fall under Chapter 38 (Miscellaneous Chemical Products) .
As such, the direct export of these finished preparations is not affected by this particular policy change. The primary impact on water treatment companies will be indirect, transmitted through increased costs of raw materials from their suppliers.
3. Policy Transition Period and the “Rush to Export”
The policy takes effect on April 1, 2026. According to the announcement, the export date declared on the customs declaration form determines which rules apply. This means goods exported before this date are still eligible for the rebate .
This timeline will likely create a short-term “rush to export” phenomenon. Suppliers of raw materials may accelerate shipments before the deadline to benefit from the current rebate rates.
For water treatment companies, this could lead to short-term volatility in raw material availability and pricing. It is essential to plan procurement and supply chain logistics accordingly to navigate this period smoothly.
In summary, the policy directly targets the export of specific organic phosphorus pesticides and, more importantly for water treatment, key inorganic phosphate raw materials like sodium hexametaphosphate.
While finished water treatment preparations are not directly targeted, the increased cost of raw materials will inevitably affect production costs. The transition period until April 1, 2026, is critical for strategic planning.
Understanding which products are affected is the first step. Next, we will explore the specific implications of these changes for the water treatment chemicals industry and discuss practical strategies for adaptation.
Concrete Impacts on the Water Treatment Chemicals Industry
This section analyzes the specific impacts of the policy change, moving beyond the listed products to explore its real-world consequences for businesses. Understanding these effects is crucial for developing effective response strategies.
The cancellation of the VAT export rebate will trigger a chain reaction across the industry, primarily affecting operational costs, forcing product innovation, and reshaping the competitive landscape.
1. Rising Cost Pressures
The most immediate impact will be increased production costs. Since key inorganic phosphate raw materials like sodium hexametaphosphate are included in the rebate cancellation list, their prices are expected to rise.
This directly increases the cost of manufacturing many water treatment chemicals, particularly scale and corrosion inhibitors that rely on these phosphates. Consequently, profit margins will be squeezed across the board.
However, the pressure will not be felt equally. Small and medium-sized enterprises (SMEs) with weaker bargaining power will be more vulnerable. They often lack the volume for bulk purchasing or long-term supply contracts that can shield against price volatility.
In contrast, larger firms or those with integrated raw material production capabilities may better absorb these cost increases. This situation could force some SMEs to either raise their prices, potentially losing customers, or face severe profit compression, threatening their market stability.

2. Pressure for Product Portfolio Optimization
Beyond simple cost pressure, this policy acts as a powerful catalyst for industry-wide product transformation.
It aligns with and accelerates a global regulatory trend towards greener chemicals, such as the EU’s push for phosphorus-free products. Companies are now under stronger pressure to reduce reliance on traditional phosphorus-based products.
Therefore, innovation is no longer just an option for growth but a necessity for survival. The focus is shifting towards developing and commercializing more sustainable alternatives. This includes phosphorus-free scale inhibitors and biodegradable flocculants, which are seeing growing demand.
Furthermore, there is a rising market for high-value, specialty chemicals, such as those designed for membrane systems and smart dosing solutions that improve treatment efficiency and reduce chemical consumption. This shift pushes the industry from competing on cost to competing on value and technological advancement.
3. Changes in the Competitive Landscape
These combined pressures will inevitably alter the competitive dynamics of the market. Companies with vertically integrated operations or strong in-house raw material production may gain a significant cost advantage, potentially strengthening their market position.
Meanwhile, technology-leading companies have a clear path to differentiate themselves. By developing high-performance, compliant products—such as advanced inhibitors that meet international standards like REACH—they can capture specific market segments less sensitive to price.
This evolution may lead to industry consolidation. While larger players might expand their share, agile SMEs can still thrive by becoming specialists in niche areas, such as creating custom formulas for challenging wastewater streams or emerging contaminants.
In summary, the policy’s impact extends far beyond export costs, driving up expenses for all, forcing a strategic shift towards greener products, and realigning competitive forces around cost control and technological innovation.
Navigating this new landscape requires more than just reacting to price changes. The following section will provide actionable strategies—from supply chain optimization to targeted R&D—to help your business not only adapt but also discover new opportunities for growth in this evolving market.
Strategic Responses
Having analyzed the policy’s impacts, it is crucial to develop actionable strategies. Proactive adaptation is key to navigating the new regulatory landscape successfully. The following measures can help water treatment chemical companies mitigate risks, control costs, and uncover new avenues for growth.
Supply Chain Optimization
To address immediate cost pressures and ensure long-term stability, a dual approach to supply chain management is essential.
Short-term Actions: Companies should promptly engage with existing suppliers to negotiate and potentially lock in raw material prices before the policy takes full effect. Simultaneously, exploring alternative suppliers in regions not affected by the rebate cancellation, such as Southeast Asian phosphate producers, can diversify risk and create competitive leverage.
Long-term Strategy:
For greater control, investing in upstream raw material production capacity or establishing long-term strategic partnerships with key suppliers can stabilize the supply chain. This vertical integration or close collaboration helps shield companies from market volatility and ensures consistent quality for critical ingredients like sodium hexametaphosphate.
