Our products are mainly derived from mineral deposits found in northern Chile. We mine and process caliche ore and brine deposits. The caliche ore in northern Chile contains the only known nitrate and iodine deposits in the world and is the world’s largest commercially exploited source of natural nitrates. The brine deposits of the Salar de Atacama, a salt-encrusted depression in the Atacama Desert in northern Chile, contain high concentrations of lithium and potassium as well as significant concentrations of sulfate and boron.

From our caliche ore deposits, we produce a wide range of nitrate-based products used for specialty plant nutrients and industrial applications, as well as iodine and iodine derivatives. At the Salar de Atacama, we extract brines rich in potassium, lithium, sulfate and boron in order to produce potassium chloride, potassium sulfate, lithium solutions and bischofite (magnesium chloride). We produce lithium carbonate and lithium hydroxide at our plant near the city of Antofagasta, Chile, from the solutions brought from the Salar de Atacama. We market all of these products through an established worldwide distribution network.

Specialty plant nutrition:

We produce four main types of specialty plant nutrients: potassium nitrate, sodium nitrate, sodium potassium nitrate and specialty blends. We also sell other specialty fertilizers including third party products. All of these specialty plant nutrients are used in either solid or liquid form mainly on high value crops such as vegetables, fruits and flowers. Our nutrients are widely used in crops that employ modern agricultural techniques such as hydroponics, green housing, fertigation (where fertilizer is dissolved in water prior to irrigation) and foliar application. Specialty plant nutrients have certain advantages over commodity fertilizers, such as rapid and effective absorption (without requiring nitrification), superior water solubility, increased soil pH (which reduces soil acidity) and low chloride content. One of the most important products in this business line is potassium nitrate, which is sold in crystalline or prill form, allowing for multiple application methods. Crystalline potassium nitrate products are ideal for application by fertigation and foliar sprays, and potassium nitrate prills are suitable for soil applications.

The new needs of more sophisticated customers demand that the industry provide integrated solutions rather than individual products. Our products, including customized specialty blends that meet specific needs along with the agronomic service provided, allow to create plant nutrition solutions that add value to crops through higher yields and better quality production. Because our products are derived from natural nitrate compounds or natural potassium brines, they have certain advantages over synthetically produced fertilizers, including the presence of certain beneficial trace elements, which makes them more attractive to customers who prefer products of natural origin. As a result, specialty plant nutrients are sold at a premium price compared to commodity fertilizers.

Iodine:

We believe that we are the world’s leading producer of iodine and iodine derivatives, which are used in a wide range of medical, pharmaceutical, agricultural and industrial applications, including x-ray contrast media, polarizing films for LCD and LED, antiseptics, biocides and disinfectants, in the synthesis of pharmaceuticals, electronics, pigments and dye components.

Lithium:

We are a leading producer of lithium carbonate, which is used in a variety of applications, including electrochemical materials for batteries, frits for the ceramic and enamel industries, heat-resistant glass (ceramic glass), air conditioning chemicals, continuous casting powder for steel extrusion, primary aluminum smelting process, pharmaceuticals and lithium derivatives. We are also a leading supplier of lithium hydroxide, which is primarily used as an input for the lubricating greases industry and for certain cathodes for batteries.

Industrial chemicals:

We produce three industrial chemicals: sodium nitrate, potassium nitrate and potassium chloride. Sodium nitrate is used primarily in the production of glass, explosives, and metal treatment. Potassium nitrate is used in the manufacturing of specialty glass, and it is also an important raw material for the production of frits for the ceramics and enamel industries. Solar salts, a combination of potassium nitrate and sodium nitrate, are used as a thermal storage medium in concentrated solar power plants. Potassium chloride is a basic chemical used to produce potassium hydroxide, and it is also used as an additive in oil drilling as well as in food processing, among other uses.

Potassium:

We produce potassium chloride and potassium sulfate from brines extracted from the Salar de Atacama. Potassium chloride is a commodity fertilizer used to fertilize a variety of crops including corn, rice, sugar, soybean and wheat. Potassium sulfate is a specialty fertilizer used mainly in crops such as vegetables, fruits and industrial crops.

Other products and services:

We also sell other fertilizers and blends, some of which we do not produce. We are the largest company that produces and distributes the three main potassium sources: potassium nitrate, potassium sulfate and potassium chloride. This business line also includes revenue from commodities, services, interests, royalties and dividends.

Our subsidiary SQM Salar holds exclusive rights to exploit the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is only entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to the Lease Agreement. Corfo cannot unilaterally amend the Lease Agreement and the Project Agreement, and the rights to exploit the resources cannot be transferred. The Lease Agreement establishes that SQM Salar is responsible for making quarterly lease payments to Corfo according to specified percentages of the value of production of minerals extracted from the Salar de Atacama brines, maintaining Corfo’s rights over the Mining Exploitation Concessions and making annual payments to the Chilean government for such concession rights. The Lease Agreement was entered into in 1993 and expires on December 31, 2030. On January 17, 2018, SQM and CORFO reached an agreement to end an arbitration process directed by the arbitrator, Mr. Héctor Humeres Noguer, in case 1954-2014 of the Arbitration and Mediation Center of Santiago Chamber of Commerce (

Centro de Arbitrajes y Mediación de la Cámara de Comercio de Santiago

) and other cases related to it.

The agreement signed in January 2018, includes important amendments to the lease agreement and project agreement signed between CORFO and SQM in 1993. The main modifications became effective on April 10, 2018 and requires an increase in the lease payments by increasing the lease rates associated with the sale of the different products produced in the Salar de Atacama, including lithium carbonate, lithium hydroxide and potassium chloride. In regard to lithium carbonate, the former rate of 6.8% on FOB sales was changed to the following structure of progressive rates based on the final sale price:

SQM Salar commits to contribute between US$10.8 and US$18.9 million per year to research and development efforts, between US$10 to US$15 million per year to the communities in close proximity to the Salar de Atacama, and 1.7% of total annual sales of SQM Salar to regional development.
