Behind the Three Consecutive Titanium Dioxide Price Hikes, Sulfur and Sulfuric Acid Costs Are Rewriting the Pricing Floor

On March 24, LB Group announced an adjustment to titanium dioxide selling prices, with domestic prices raised by RMB 1,000 per ton and international prices increased by US$150 per ton on top of current levels. On the same day, companies including Guangdong Huiyun Titanium, Tineng Chemical, Shengwei Fuquan Chemical, and Zhengtai New Materials also issued notices matching the same increase. By March 25, 25 companies had intensively released price increase letters, with the market generally seeing a rise of RMB 1,000 per ton. Combined with LB Group’s three consecutive price hikes on March 2, March 16, and March 24, this latest titanium dioxide rally is no longer an ordinary “follow-the-trend” price increase, but a systemic move upward jointly driven by cost pressure, low inventories, and stronger exports.

What makes this round of price increases especially striking is not just that prices rose three times, but that each increase was stronger than the last. The mid-March round was still a domestic increase of RMB 500 per ton and an export increase of US$100 per ton. By March 24, it had already jumped to RMB 1,000 per ton domestically and US$150 per ton for exports. The price rhythm has clearly accelerated, which indicates that companies’ internal ability to absorb costs is rapidly approaching its limit. Market analysis has pointed out that by March 24, titanium dioxide price indices had already risen significantly year to date, while low inventories, improved exports, and geopolitical disruptions amplified bullish market sentiment. In other words, current titanium dioxide prices are not being driven simply by producers “wanting to raise prices,” but by upstream costs and supply-demand expectations pushing them upward together.

What is really driving this market is not titanium dioxide itself, but the sulfur–sulfuric acid–sulfate-process titanium dioxide cost chain behind it. As shipping uncertainty in the Strait of Hormuz increased, the global sulfur trade tightened significantly. Recent market data show that sulfur prices in China continued rising through March, and port sulfur prices in late March had already climbed to around RMB 5,500 per ton. Sulfur itself is not titanium dioxide, but it determines sulfuric acid costs, and sulfate-process titanium dioxide consumes sulfuric acid in very large volumes, which means every jump upstream is written directly into the manufacturing cost of titanium dioxide.

That is also why titanium dioxide producers have issued price increase letters in such a dense, coordinated, and almost simultaneous way. Under the sulfate-process route, each ton of titanium dioxide typically consumes large amounts of sulfuric acid, making costs extremely sensitive to sulfur and sulfuric acid prices. Public industry analysis generally points out that the continued rise in sulfuric acid prices has become the single most important factor driving titanium dioxide price increases. Put more directly, titanium dioxide producers are not taking the initiative to expand profits right now, but are passively repairing costs. If prices do not move up in step, margins will be rapidly swallowed by raw material costs.

But it would still be incomplete to explain this round simply as “cost pass-through.” The reason titanium dioxide has been able to rise three times in a row is also that inventories are not high, and exports are not weak. Multiple market sources recently noted that overseas orders have improved, with some producers already booked through May or even June, which has lowered inventory levels. That means if upstream costs had risen while producers were sitting on large inventories and downstream buyers refused to take goods, price increase letters would not necessarily have created real market force. The issue now is precisely that titanium dioxide producers do not have enough stock on hand to sell cheaply at will, while overseas demand has given them stronger pricing power.

This gives the current three consecutive increases a very obvious feature: this is not a price rise driven by comprehensive demand expansion, but a cost-push increase under low inventory conditions. The distinction matters. The former means companies benefit from both higher volumes and higher prices. The latter means upstream producers are first protecting margins while downstream is forced to absorb the pressure. For major titanium dioxide-consuming sectors such as coatings, plastics, rubber, and inks, this is clearly not a comfortable situation. Small and medium-sized downstream companies in particular often already operate with thin margins, and now face a rapid rise in pigment costs while finished product prices cannot necessarily follow immediately. For leading producers, higher titanium dioxide prices may mean margin repair; for weaker downstream players, they look much more like a new round of cost compression.

At a deeper level, this round of three consecutive increases also shows that the operating logic of the titanium dioxide industry has changed. In the past, many companies faced with upstream raw material volatility would first wait, absorb, and try to rely on inventory buffers. Now, mainstream producers are becoming increasingly inclined to raise prices faster, pass costs through earlier, and rebuild price floors more directly. The reason is simple: external disruptions are no longer one- or two-day shocks, but long-duration variables carrying clear geopolitical and supply risk. Once the Strait of Hormuz becomes unstable, sulfur stops being just another ordinary chemical raw material and becomes a strategic cost item carrying a transportation risk premium. If companies continue selling new-cost products at old prices, they are effectively giving away their margins. Three rounds of price increases almost forming a straight line indicate that titanium dioxide producers are no longer willing to continue acting as the industry’s “cost buffer.”

Of course, whether prices can remain firm will still depend on downstream acceptance in April and into the second quarter. Market analysis has also warned that sustainability will depend on how well downstream can absorb higher prices after the traditional peak season. The issue now is that many end users and distributors have already completed a stage of advance stocking, meaning some demand has been brought forward. In other words, after three consecutive increases, the market is about to enter a stage that will test real digestion capacity much more directly. If sulfur and sulfuric acid remain at high levels while downstream cannot continue replenishing, titanium dioxide prices may not necessarily fall back quickly, but the ability to keep rising at the same steep pace will weaken. On the other hand, if Middle East tensions continue to disturb markets and raw material prices rise again, titanium dioxide prices will likely remain supported and could even test still higher offers.

Based on current market conditions, titanium dioxide costs are unlikely to fall significantly in the short term. Sulfur prices remain elevated, recovery in Hormuz traffic is still uncertain, and the sulfuric acid market has not genuinely loosened. In this environment, spot titanium dioxide prices will most likely continue to operate at a high center. For producers, the more important issue now is no longer “whether to raise prices,” but how to maintain shipment rhythm between high costs and high offers. For downstream players, the more practical issue is no longer “have prices risen,” but “whether procurement strategy needs to change.” If supply remains tight after April and order books continue to fill, the market will further reinforce expectations that prices are “easier to rise than to fall.”

Taken together, the three consecutive titanium dioxide price hikes in March are not one company leading the market, but a full price reassessment driven jointly by sulfur, sulfuric acid, exports, inventories, and geopolitical risk. LB Group has raised prices by a cumulative RMB 2,000 per ton across three rounds, while 25 companies have followed, showing that the market has shifted from isolated adjustments to an industry-wide upward reset. For the titanium dioxide sector, this round of price increases is first about cost repair, and only second about profit improvement. For downstream industries, it means raw material procurement strategy, inventory management, and finished product pricing all need to be recalculated. In the end, the two variables that will still determine price direction are whether the Strait of Hormuz can recover and whether sulfur and sulfuric acid prices can come back down. Until there is a clear turning point in those two issues, titanium dioxide is likely to remain at high levels.
