US tariff pause brings relief to fertilizer exporters

President Donald Trump delayed his ‘liberation day” tariffs by three months on 9th April, while simultaneously ramping up levies on China. In this latest twist to the on-off US tariffs saga, the Trump administration’s 90-day pause on additional duties should provide international suppliers to the world’s biggest fertilizer market with some respite – for now. With the exception of China, the US will now cut back its so-called ‘reciprocal tariffs’ to 10% for the duration of a three-month suspension period. The European Union’s tariff is now halved to 10%, for example, with the trade bloc also pausing its trade countermeasures against the US.

Start-up for Adani smelter

Adani Group subsidiary Kutch Copper has commenced operations at its new Mundra copper refinery and smelter, the company announced on 28 March. The company previously indicated an expected start-up by the end of Q1. The new smelter will help boost domestic supplies of copper, demand for which is robust from the construction, transport and power sectors in particular and likely to double by 2030, with the shift towards clean energy and electric vehicles. This first phase of the project will have around 500,000 t/a copper capacity, with a similar capacity planned to be added in the second phase by 2029.

Production cuts at Chinese smelters

It is reported that Tongling Nonferrous is planning production cuts this year given current record low treatment and refining charges (TC/RCs). CRU estimates that the company’s potential cutbacks will total 67,000 tonnes of copper for the year. However, the start-up of the Jinguan II and Chifeng Jinjian II projects could offset the reduction in concentrate demand at operational smelters. Tongling Nonferrous owns five operational smelters/refineries with a total of 1.28 million t/a blister capacity and 1.73 million t/a refined capacity, respectively. It is understood that the Chifeng Jintong 220,000 t/a smelter has cut operating rates by 10% since early March due to concentrate tightness.

Daewoo to build phosphoric acid plant

Daewoo Engineering & Construction has signed a $700 million framework agreement to build a fertilizer plant in Turkmenistan. The agreement was signed in Seoul with Turkmenistan's state-owned chemical firm, Turkmenhimiya, according to the Turkmen Ministry of Trade, Industry and Energy, noting the Korean firm was named the preferred bidder for the project in October. The project aims to construct a fertilizer plant that will extract phosphoric acid from phosphate rocks and process the substance into 300,000 t/a of annually in eastern Turkmenistan by 2029.

Cornerstone sells sulphuric acid operations

Cornerstone Chemical Company has sold its sulphuric acid operations to Ecovyst, a global provider of advanced materials, specialty catalysts, sulphuric acid and regeneration services based in Malvern, Pennsylvania. Ecovyst's business structure includes two core business units: Advanced Materials and Catalysts (AM&C) and Ecoservices. Ecovyst more than 900 employees throughout its 12 facilities across multiple locations worldwide and its Ecoservices division is a North American provider of sulphuric acid and sulphuric acid regeneration services.

Price Trends

Sulphur markets have been on a tear over the past few months, driven by strong demand in Asia, with buyers primarily sourcing from the Middle East and Canada through late 2024 and into the early months of 2025. Steady buying from Indonesia and China, the two largest importers of sulphur, appears to have supported the market, in China’s case mainly for phosphate production as well as a variety of industrial processes, and in Indonesia’s case to feed the high pressure acid leach (HPAL) plants that are producing nickel for the battery and stainless steel industries. Prices saw a notable rally following the Chinese Lunar New Year celebrations. Nevertheless, this momentum finally began to shift as April began ago as the pace of price increases in Asia started to slow. As the spring fertilizer application season in China draws to a close, domestic prices began to drop, reaching the equivalent of a delivered price of around $272/t c.fr. As well as the narrowing window for spring application of phosphates, the decline was also driven by weakening demand amid uncertainty over tariffs and export restrictions. In southern China, phosphate producers continue to purchase import cargoes. A major phosphate producer in southwest China has been reported as having bought mainstream material at a price of $303/t c.fr, according to local market sources. Total sulphur port inventories in China had declined by 22,000 tonnes to 1.86 million tonnes by 16 April 2025. The volume at Yangtze River ports increased to 825,000 tonnes, while the port inventory at Dafeng decreased to 400,000 tonnes.
