The global oxalic acid dihydrate market was valued at USD 575 million in 2025. The market is projected to grow from USD 608 million in 2026 to USD 969.07 million by 2034, exhibiting a compound annual growth rate of 6% during the forecast period. Contrive Datum Insights presents this information in its report titled "Oxalic Acid Dihydrate Market Size, Share & Industry Analysis, By Grade (Industrial Grade, Technical Grade), Application (Rare Earth Metal Extraction, Textile & Leather Processing, Metal Cleaning & Surface Treatment, Bleaching Agent (Pulp & Paper), Pharmaceutical & Chemical Synthesis, Others), End-use industry (Chemical & Metallurgical, Textile & Leather, Pharmaceutical, Pulp & Paper, Others), Form (Powder, Granules & Crystals), Distribution channel (Direct Sales (B2B), Distributors & Traders), and Regional Forecast, 2026-2034".
Oxalic acid dihydrate is the crystalline, hydrated form of oxalic acid, a dicarboxylic acid produced synthetically from carbohydrate or petrochemical feedstocks and supplied as technical or industrial grade powder, granules or crystals. It is bought by rare earth processors for metal separation and purification, by textile and leather finishers for bleaching and dyeing preparation, by metal treatment operations for surface cleaning and pickling, and by pharmaceutical and specialty chemical manufacturers as a synthesis intermediate. Buyers range from large industrial processors purchasing under direct supply contracts to smaller specialty manufacturers sourcing through chemical distributors.
Rare earth element extraction and magnet supply chain expansion
Rare earth element extraction and magnet supply chain expansion is the largest single contributor to the market's growth over the forecast period, and the study rates its impact high. Against a market growing at 6% a year, the grade lines exposed to it move fastest: Technical Grade compounds at 6.59%, taking its share of revenue from 38.07% to 40% and its value from USD 218.91 million to USD 387.63 million.
On the upside, the study's bull case assumes rare earth processing capacity comes online faster than currently announced and pharmaceutical intermediate demand grows above trend, pulling realised prices upward across both grades, which would take 2034 revenue to USD 1065.98 million against the USD 969.07 million base case.
The downside is specific. Rare earth processing capacity additions slip and textile and metal treatment demand growth slows with broader industrial output, holding realised prices closer to current levels, and 2034 revenue lands at USD 872.16 million. Industrial Grade is the drag, 61.93% of the 2025 base compounding at 5.63% while the market runs at 6%.
