Diatomite Prices, Demand and Supply Overview
In Germany, the highest-cost reporting region, Diatomite prices moved only roughly 0.2% in Q3 2026, moving from close to USD 647/MT in Q2 to about USD 646/MT in Q3, and it was stable calcining costs and balanced orders from filtration and building material buyers that most plausibly shaped the move. Across the tracked regions, the global average moved from near USD 514/MT in Q2 to just under USD 514/MT in Q3, a change of just above 0.0%. For Q4 2026, a global average of roughly USD 499 to 535/MT is expected, with energy costs, grade mix, and filtration demand guiding the range.
Diatomite, also called diatomaceous earth, is a soft siliceous sedimentary rock made of fossilised diatom shells, and it is mined, milled, and sold in natural, calcined, and flux calcined grades with silica content of eighty percent or more. It is used mainly as a filter aid for beer, wine, juice, edible oils, and pharmaceuticals, and also as a functional filler in paints and plastics, a carrier in agrochemicals, and an insulation material, with filtration taking the largest share of demand. Mining and calcining energy costs, grade mix, beverage and oil filtration demand, and freight rates all feed into the price.
Diatomite Price Forecast for 2026
The balance of supply and demand for diatomite through the end of 2026 leans stable. Chinese quotes for the 86 percent grade were unchanged from August through October, and the market rates the price as low for the year. Filtration demand has been steady, which supports the current range.
The main upside risk is a rise in natural gas and energy costs or mine restrictions that tighten supply of filter aid grades and lift prices above the forecast range. The main downside risk is weaker beverage and edible oil demand, which would pull prices below the forecast.
| Region | 2026 Price Range (USD/MT) | Outlook |
| Global Average | 499 - 535 | Stable energy costs guide the range |
| China | 396 - 424 | Large deposits keep China lowest |
| Mexico | 460 - 493 | Export links hold a lower middle |
| United States | 510 - 547 | Filter aid quality holds a firm level |
| Germany | 627 - 672 | Purity rules and imports hold the top |
