## What boron is used for

Boron (B) reaches industry mostly as **borate minerals**, and its largest use is in **glass**: insulation fibreglass, textile glass fibre for composites, and the heat-resistant borosilicate glass of laboratory ware, cookware and display panels. **Agriculture** is the next market, as boron is an essential micronutrient for crops. It also plays a quiet part in clean energy, as the "B" in **neodymium-iron-boron magnets** and as the neutron absorber in nuclear control rods.

### Other uses

- Ceramics, glazes and enamels
- Boron carbide for armour and abrasives
- Detergents and bleaches
- Flame retardants and wood preservatives

## Boron supply and demand factors

Boron supply is dominated by two producers: Turkey's state-owned miner and a US operation in California, with smaller output from South America. That concentration makes the market orderly, as most borates trade on contract rather than on an exchange. Demand follows **glass fibre, ceramics and agriculture**, with a smaller but growing contribution from magnets and nuclear uses.

### What moves the price

- Production and pricing decisions by the two dominant producers
- Fibreglass insulation and composites demand
- Crop prices and fertiliser use
- Ceramic tile output

## Boron price history

Borates trade mostly on contract, so boron prices move gradually rather than in spikes. The biggest changes in recent years came from the energy and freight inflation of 2021 and 2022, which producers passed through to customers, rather than from shortages.

As of October 2026, the Stockatomics benchmark price is $5.27 per kg contained.

## Where boron is produced

Borate production is dominated by **Turkey**, home to the world's largest reserves, and the **United States**, which mines at Boron in California. Chile, Argentina, Bolivia and Russia make up most of the rest.

## Why boron is a critical mineral

Boron was added to the **US critical minerals list** in 2025 and is on the **EU critical raw materials list**. Glass fibre, agriculture, permanent magnets and nuclear control rods have few substitutes for it, and borate supply sits mainly with two producers, in Turkey and the United States.

## How the boron benchmark price is calculated

Stockatomics publishes a monthly US benchmark price for boron in US dollars per kg contained, reading as of October 2026. It is a contained-boron price, which puts the many borate products, from boric acid to refined borates, on the same footing. It is not a price for a particular borate grade or for fibreglass.

### Converting the price

- Boric acid contains about 17.5% boron, so a kilogram of boric acid carries about 0.175 kg of boron
