White Cardboard Holds, Corrugated Swings: The Industrial Concentration Logic Behind Paper Price Divergence

White cardboard has drawn considerable market attention after a six-month rally, with prices leading the pack during peak season and refusing to crack in the off-season. Only days ago, the sector's leading producer announced another 600 yuan increase, reigniting the upward momentum.

Corrugated paper, a workhorse grade for packaging, tells a different story. It followed the late-year price wave upward, peaked in March this year, and has since retreated to levels close to early February. Corrugated paper may climb quickly, but its momentum is much weaker than white cardboard's, and its declines are swift. That boom-bust pattern is a headache for many downstream carton plants: when paper costs jump, customer order prices cannot keep pace; when paper prices fall, stockpiled material loses value and customers become less eager to order. The industry is left asking why two paper grades can behave so differently.

White cardboard's strength stems not only from a favorable policy window but also from its concentrated industry structure. Statistics show that the four largest domestic white cardboard producers by annual capacity are APP, Bohui Paper, Chenming Paper and Sun Paper, and these four giants control nearly 90% of the domestic market.

That high concentration creates powerful linkage. When one producer raises prices, others quickly follow; when prices decline, leading players tend to band together to defend levels. As a result, white cardboard prices are prone to rising and resistant to falling.

Corrugated paper, by contrast, operates in a much more fragmented market. Mills of different sizes are scattered across the country, and concentration remains low. This structure makes prices prone to both rapid increases and rapid declines, and in weak markets it can even trigger a rush to liquidate stock.

Why do two paper grades differ so sharply in industry structure? One key factor is how far mills have integrated upstream raw materials.

Most domestic white cardboard producers have already moved toward integrated forest-and-pulp operations, with new projects continually being developed. The projects brought online by major players over the past two years have focused mainly on capacity expansion and forest-and-pulp layout. The strategic value of forest-pulp-paper integration is clear.

By controlling upstream raw materials, white cardboard producers have strengthened both pricing power and profit margins, and can use lower prices to win market share. Even if their selling price falls below the market level, relatively cheap raw materials can still generate an intermediate profit, allowing them to avoid losses, or earn a slim profit, while maximizing market share. This is one secret behind the leading white cardboard producers' firm grip on the market.

White cardboard producers without upstream raw material operations, by contrast, are disadvantaged in both raw material and price competition. In all likelihood, they will be acquired by stronger paper companies or eliminated by the market.

Corrugated paper's upstream raw material is mainly waste paper. With the full implementation of the imported waste paper ban, supply is now even more concentrated in domestic waste paper. According to incomplete statistics, there are more than 100,000 waste paper recycling and baling stations nationwide, making integration extremely difficult. Clearly, raising industrial concentration by controlling upstream raw materials is unrealistic for the corrugated paper market.

The difficulty of integrating upstream raw materials leaves corrugated paper producers with limited bargaining power. Profits are constantly exposed to raw material price swings, and mills struggle to secure a basic margin from the raw material side. They can only adjust prices in step with raw material costs and may even lose the initiative when dealing with the upstream market.

Fragmentation downstream also keeps pricing power dispersed among corrugated paper producers, leaving little room to gain an edge through pricing strategy. Unlike white cardboard giants, which can still profit on the raw material side even after cutting prices, corrugated paper producers that enter a price war are likely to hurt each other.

Price battles among corrugated paper producers also spill over to downstream carton plants. When corrugated paper producers push through price increases, higher costs are clearly unwelcome for carton plants.

If corrugated paper producers shift to price cuts, downstream carton plants may then face order hesitation from end customers. End customers also watch paper prices closely; when prices keep falling, they wait to see whether the decline will continue, potentially delaying orders to carton plants. Some even cite falling paper prices to demand matching price cuts from carton plants, another pressure point for carton converters.

The current upstream and downstream structure means corrugated paper cannot, for now, follow the development path of white cardboard. So is there a way to improve the passive position of corrugated paper producers on both the upstream and downstream sides?
