Stainless Steel Brought Under Full Regulation: Where Lie the Tough Red Lines in MIIT’s New Rules?

On May 18, 2026, the Ministry of Industry and Information Technology (MIIT) issued the revised Measures for the Implementation of Production Capacity Replacement in the Iron and Steel Industry (MIIT Yuan [2026] No. 97), which took effect on the date of issuance and repealed the 2021 version simultaneously. The core of the new rules includes implementing nationwide unified high-proportion capacity reduction replacement, imposing strict controls on cross-enterprise capacity flow, and formally incorporating stainless steel into production capacity assessment. This marks a shift in China’s iron and steel capacity governance from regionally differentiated management to unified nationwide regulation, with the governance philosophy upgraded from mere capacity control to a combination of capacity regulation, low-carbon development and industrial consolidation. As the first set of rules to bring stainless steel production capacity under supervision, the new measures will exert a far-reaching impact on the future supply landscape, business operations and long-term development of the stainless steel sector.

I. Core Differences Between the 2021 and 2026 Capacity Replacement Rules

1. Unified Replacement Ratio & Preferential Policies for Mergers and Restructuring

The old rules adopted regionally differentiated replacement standards: the replacement ratio was no less than 1.5:1 in key areas for air pollution prevention and control, and no less than 1.25:1 in other regions. Such regional disparities left room for enterprises to profit from capacity arbitrage.

2. Restrictions on Free Capacity Trading & Incentives for Enterprise Mergers

A two-year transition period (2026–2028) is stipulated under the new rules. Upon the expiry of the transition period, pure cross-enterprise capacity replacement will be prohibited. Capacity transfer will only be permitted through substantial mergers and restructuring involving changes in controlling rights and equity holdings.

Capacity quota trading will gradually decline, and the value of nominal idle capacity will keep falling. This compels enterprises to abandon the model of expanding production by purchasing quotas and accelerates industrial consolidation.

3. Stainless Steel Included in Regulation to Fill Industry Supervision Gaps

Stainless steel production capacity had long been excluded from capacity replacement assessment under the old rules. Many enterprises built induction furnaces in the name of alloy smelting, resulting in disorderly new steelmaking capacity, severe overcapacity and a long-term capacity utilization rate below 75%.

For the first time, the new rules integrate stainless steel into the unified assessment system for iron and steel capacity. They set strict standards for induction furnace construction, requiring the volume and quantity of equipment to match production processes. Unauthorized new steelmaking capacity is strictly banned to curb blind expansion of stainless steel capacity at the source.

4. Optimized Differentiated Policies to Support High-end Special Steel

The new rules ramp up support for high-end special steel and low-carbon smelting. Preferential policies are tilted toward hydrogen metallurgy and electric furnace short-process production. High-end stainless steel and special alloys are eligible for differentiated replacement policies. Electric furnaces for restricted categories of high-end special steel may adopt a 1:1 equivalent replacement ratio. The clear policy orientation drives the industry toward high-end and green transformation.

II. Impacts of the New Rules on the Stainless Steel Industry

1. Halted Capacity & Output Expansion and Optimized Supply-Demand Balance

First, inefficient capacity will be phased out at a faster pace. Small and medium-sized manufacturers of low-end stainless steel face mounting pressure from rising costs for technological renovation and capacity replacement. Small plants lacking compliant capacity and featuring high energy consumption will be gradually eliminated, accelerating the exit of backward low-end capacity.

Second, output growth will continue to slow. Previously, China’s stainless steel output posted an annual growth rate of around 6%. Following the implementation of the new rules, the growth rate will drop to 1%–2% in the coming years. The industry will shift from cutthroat competition amid overcapacity to a tight supply-demand balance, providing stronger bottom support for stainless steel prices.

2. Divergent Business Performance & Growing Advantages of Industry Leaders

Leading enterprises will gain new development opportunities. Major players including Tsingshan, TISCO and Baowu boast strengths in compliant capacity, capital and technology. Leveraging preferential policies for mergers and restructuring, they can integrate small and medium-sized capacity at low cost and expand market share. Meanwhile, policy support for high-end special stainless steel will help top enterprises raise the proportion of high-value products and improve profitability, steadily lifting industrial concentration.

Small and medium-sized manufacturers face heightened operational pressure. Blocked from capacity expansion and burdened by high costs for environmental protection, energy conservation and low-carbon upgrading, their cost disadvantages keep widening. A clear industrial divergence has taken shape. SMEs with professional features focusing on precision pipes and special steel plates can follow the path of specialized, refined, distinctive and innovative development. In contrast, low-end processing enterprises lacking core technologies and unique advantages will either be acquired or withdraw from the market.

3. Stainless Steel Industry Shifts toward Capacity Control, Quality Improvement and Carbon Reduction

First, total supply is capped. The rampant expansion of the stainless steel sector has come to an end. The industry now adheres to the principle of controlling new capacity and cutting existing capacity, shifting competition from scale expansion to competition in quality, technology and cost.

Second, product mix is upgraded. Capacity for low-end 200-series and conventional 300-series stainless steel will gradually shrink. Supported by favorable policies, high-end materials such as duplex stainless steel, super stainless steel and nickel-based alloys will realize import substitution with a rising market share.

Third, production goes greener. The new rules encourage electric furnace short-process smelting, which will account for a larger share in stainless steel production. Low-carbon smelting technologies such as hydrogen-based shaft furnaces will be gradually deployed to reduce industrial carbon emissions.

Fourth, industrial consolidation becomes normalized. Restrictions on capacity trading after the transition period will make mergers and acquisitions the only way for enterprises to expand, fundamentally rectifying the fragmented and inefficient industrial structure.

III. Conclusion

The new capacity replacement rules for the iron and steel industry constitute a key initiative for supply-side structural reform. Its core objectives are to cap total production capacity, facilitate enterprise consolidation and steer the industry toward low-carbon and high-end development. Incorporating stainless steel into capacity assessment stands out as the biggest highlight, addressing long-standing regulatory gaps.

In the short term, the new rules curb disorderly expansion of stainless steel capacity and speed up the phase-out of backward capacity. In the long run, they optimize the supply-demand structure, ease vicious price competition and enhance the overall profitability stability of the industry.

Going forward, the stainless steel industry will see higher concentration, upgraded high-end products and greener production. Leading enterprises will further consolidate their competitive edges, while SMEs will accelerate transformation and upgrading. The entire sector has officially entered a stage of high-quality development.
