Sulfuric acid prices rose sharply through the first half of 2026 before retreating from their mid-year peak as supply conditions loosened. Weak downstream demand has contributed to the easing, though the commodity remains a critical revenue buffer for copper smelters facing squeezed processing margins. The price trajectory reflects the interplay between by-product supply dynamics and broader industrial demand.
China's 98% smelting sulfuric acid price eased over the week as spot trading weakened and recovering supply added pressure. Elevated sulfur and metal ore costs provided partial support, but the market faces further downside as lower-priced regional supplies increase competitive pressure.
Asia
The Asian sulphonated naphthalene market experienced slight downward price pressure during the fourth quarter, with the Indian market demonstrating progressive weakening through most of the period. Prices declined gradually as supply conditions remained comfortable and downstream demand from construction chemicals and concrete admixture sectors showed measured activity. Procurement from ready-mix concrete manufacturers and construction material producers remained cautious, with buyers maintaining conservative purchasing strategies amid moderate infrastructure project activity. Demand from textile auxiliary applications for dye dispersants demonstrated steady but uninspiring consumption levels, while leather tanning chemical sectors generated baseline procurement volumes. The latter portion of the quarter witnessed price stabilization as the declining trajectory moderated and market participants adjusted to prevailing supply-demand balances. Dispersing agent applications across various industrial sectors maintained regular order patterns, though overall consumption growth remained limited throughout the period.
Europe
European sulphonated naphthalene markets demonstrated range-bound price movements during the fourth quarter, fluctuating within established trading bands as supply-demand dynamics remained balanced. Prices oscillated without sustained directional momentum as production capacity aligned with downstream consumption requirements. Demand from construction chemical formulations and concrete plasticizer applications showed measured activity, with infrastructure projects generating consistent but moderate procurement levels. Textile processing applications for dye dispersion maintained steady consumption patterns, while industrial dispersing agent sectors demonstrated baseline purchasing activity. Market participants adopted cautious trading approaches, with buyers maintaining need-based procurement strategies and suppliers offering stable quotations throughout the period.
North America
North American sulphonated naphthalene markets experienced slight upward price movement during the fourth quarter, influenced by rising feedstock naphtha costs that elevated production economics. Prices demonstrated progressive appreciation as manufacturers adjusted offer levels to reflect increasing input costs. Demand from construction chemicals and concrete admixture applications remained steady, with infrastructure development projects providing baseline consumption support. Ready-mix concrete producers maintained regular purchasing patterns, while industrial dispersing agent applications across coatings and specialty chemical sectors generated measured procurement activity. The upward trend reflected cost-push dynamics as feedstock price appreciation translated through the supply chain.
Analyst Insight
According to Procurement Resource, sulphonated naphthalene prices are expected to maintain relative stability as supply-demand fundamentals remain balanced and downstream demand from construction chemicals and textile applications shows gradual improvement.

Asia
The price movement of Sulphonated Naphthalene in Asia was significantly upward during the second quarter. The prices were about 1330 USD/MT (FOB) in April and around 1340 USD/MT in June in India. The market steadily increased from the start of the quarter, presumably due to the rise in demand from major industries. The prices went up consistently as the demand increased, indicating the tight supply and consumption dynamics. The increase in prices is also a result of the feedstock behavior, including Naphtha, which experienced fluctuations throughout this timeframe. The steady increase in prices of Sulphonated Naphthalene reflected that Asian markets were, to some extent, able to absorb the increased input costs but still ensured a stable demand-supply equilibrium to support the price increase in the region.
Europe
In Europe, the Sulphonated Naphthalene market was more volatile in its price direction. Prices initially experienced a slight increase, led by solid demand and scarce supply levels. The market, however, later experienced a softening trend in the latter part of the quarter. This was in some part because of the more volatile nature of its main feedstock, Naphtha, which experienced some instability over the quarter. The Sulphonated Naphthalene prices, while tracking the trends of Naphtha prices, stabilized eventually as the market adapted to supply and demand movements. The market also experienced some softening towards the end of the quarter, which might have been caused by dampened buying activity from key consumers. The price action in Europe reflected this general trend of fluctuation.
North America
In North America, the Sulphonated Naphthalene trend price was subject to a host of factors such as fluctuations in the prices of feedstocks like Naphtha, and the downturns in the agricultural and construction industries. The market began on a weak note, which was a reflection of the initial weakness in demand. But by the latter part of the quarter, prices started to recover on the back of increasing demand from sectors like agriculture and the construction industry, for which Sulphonated Naphthalene finds extensive applications. The price improvement in North America found support in both supply-side considerations and increasing costs of inputs. In spite of the oscillating market in the initial phases, the later part of the quarter witnessed partial recovery, bearing witness to a general range-bound trend for the market.
Sulphonated naphthalene is an aromatic sulfonic acid derivative produced by introducing sulfonic acid groups into naphthalene molecules. It is widely used as an intermediate for manufacturing dispersants, surfactants, and specialty chemicals. Its strong dispersing properties make it valuable in industries requiring improved flow, stability, and uniform distribution of materials.

Sulphonated naphthalene production involves sulfonating purified naphthalene, neutralizing the resulting acid, and processing it into sodium salts or condensed products. Manufacturers control reaction temperature, acidity, and purification steps to produce consistent grades used in concrete additives, detergents, dyes, and industrial chemical applications.
Sulphonated naphthalene derivatives are mainly used in construction chemicals as raw materials for naphthalene sulfonate formaldehyde (SNF) superplasticizers in concrete admixtures. They are also used in dyes, textiles, leather processing, detergents, agrochemicals, and chemical formulations where dispersing and wetting properties are required.
