Mercer International Inc. (MERC) is a global manufacturer primarily engaged in the production and marketing of northern bleached softwood kraft (NBSK) pulp.

Its pulp products are distributed internationally, reaching markets in Europe, the United States, Asia, and other regions.

The company's operations are divided into two main segments: Pulp and Wood Products. Beyond pulp, Mercer also plays a role in sustainable energy, generating and supplying green electricity derived from its biomass cogeneration power plants to various third-party utility providers. Furthermore, the company is involved in the manufacturing, distribution, and sale of lumber and other valuable wood residuals. The primary feedstocks for its NBSK pulp production include wood chips, pulp logs, and sawlogs.

Its carbon-neutral or "green" energy is generated using sustainable bio-fuels such as black liquor and wood waste.

Additionally, Mercer produces tall oil, which serves as both a chemical additive and a green energy source. Mercer's pulp is a key ingredient for manufacturers of tissue, specialty paper, printing and writing paper, and other paper products.

Its lumber goods reach a diverse customer base, including distributors, construction firms, secondary manufacturers, retail yards, and home centers. Established in 1968, Mercer International Inc. maintains its corporate headquarters in Vancouver, Canada.
