Export Tax Rebate Cancellation Reshapes China's Methyl Silicone Oil Industry: From Price-Led to Value-Led Competition

The Chinese methyl silicone oil industry is experiencing a watershed transformation in 2026 following a major policy shift. On January 9, China's Ministry of Finance and State Taxation Administration jointly issued an announcement canceling the 13% VAT export tax rebate for primary-form polysiloxanes—including methyl silicone oil, 107 rubber, vinyl silicone oil, and hydrogen-containing silicone oil—effective April 1, 2026.

The Policy Shockwave: A 13% Rebate Elimination

With methyl silicone oil market prices quoted at approximately 16,000-17,800 RMB/ton in April 2026, the cancellation of the 13% rebate increases per-ton export costs by approximately 2,000-2,300 RMB. For an industry that has long relied on export volumes with thin profit margins often below 5%, this policy represents a significant stress test.

The three-month policy buffer period (January-March) triggered a "rush-to-export" surge. Industry data shows that domestic silicone exports increased approximately 15% month-over-month in January 2026 as manufacturers accelerated production to fulfill overseas orders before the April deadline.

Price Dynamics: From Surge to Correction

The methyl silicone oil market experienced a characteristic surge-then-correction pattern following the policy announcement:

Pre-Policy Run-up (October 2025-March 2026): Silicone DMC prices rose steadily from lows of 11,300 RMB/ton in October 2025 to 14,700 RMB/ton by late April 2026, a cumulative increase of 30%. Methyl silicone oil followed this trend, rising to 16,000-17,800 RMB/ton.

Post-Policy Outlook (April onward): Industry analysts warn that post-policy, elevated export costs will suppress overseas orders. Combined with demand pull-forward from pre-deadline "rush orders," the supply-demand balance may weaken, creating downward price pressure in the second quarter.

Short-Term Pain, Long-Term Gain

While the immediate impact of export rebate cancellation is increased costs and potential volume decline, the policy is widely viewed as a catalyst for long-term industry transformation.

Direct Cost Impact: Using 107 rubber at approximately 14,200 RMB/ton as an example, rebate cancellation increases export costs by approximately 1,600 RMB/ton. This cost must be absorbed by exporters, passed to overseas customers, or offset through operational efficiencies.

Competitive Positioning: China's silicone capacity accounts for over 70% of global supply, with overseas production capacity continuing to contract—including planned exits of approximately 145,000 tons of capacity in 2026. Overseas customers face significant difficulty finding alternative supply sources, enabling Chinese producers to partially pass increased costs through higher export prices.

Structural Upgrade Driver: According to industry analysis, the rebate adjustment effectively redirects resources from low-value-added, homogeneous competition toward high-tech, high-margin specialty segments. This will accelerate domestic silicone companies' product upgrades and technological innovation toward electronic-grade, medical-grade, and specialty functional silicone oils.

Dual Pressures: Environmental Standards Tighten

Beyond export policy changes, the methyl silicone oil industry faces tightening environmental regulations. The new Chinese national standard GB 4806.16-2025 "National Food Safety Standard – Silicone Rubber Materials and Products for Food Contact" is set for mandatory implementation on September 2, 2026, imposing stricter volatile organic compound (VOC) limits and raw material restrictions.

These regulatory developments are accelerating industry consolidation. Companies lacking purification capabilities, advanced manufacturing processes, or environmental compliance systems face increasing pressure. According to third-party estimates, approximately 30% of low-end products currently on the market fail to meet the new VOC limit requirements.

Long-Term Industry Implications

The policy "combination punch"—from export tax rebate cancellation to environmental standard upgrades—is accelerating the methyl silicone oil industry's transition from "volume-driven expansion" to "quality-driven value creation." Several long-term trends are emerging:

1. Market Consolidation Accelerating: The industry's top five manufacturers' market share (CR5), currently approximately 68%, is projected to reach 75% by 2027 as smaller, less efficient producers exit the market.

2. Premium Product Share Increasing: Commodity-grade methyl silicone oil growth is slowing, while electronic-grade, medical-grade, and cosmetic-grade high-purity, low-cyclic products are becoming the growth drivers. The share of premium products is expected to increase from approximately 20% to over 35% by 2030.

3. Export Structure Optimizing: While short-term export volumes may decline, the policy will force export products to upgrade from low-priced commodity goods to high-value-added specialty products.

4. Innovation Investment Rising: Companies are redirecting resources from price competition to R&D investment in high-purity synthesis, low-volatility formulations, and functional modification technologies.

The era of relentless price competition is fading. The value-led competition era, driven by technological innovation and quality differentiation, has arrived.
