Common products:
Brazil nut kernels (raw or roasted) and Brazil nut oil are the principal commercial products of Bertholletia excelsa. Kernels are widely used in confectionery, desserts, baked goods, granola, and chocolate. Shells, which are hard and lignocellulosic, are used as activated carbon and as a granular sorbent and mulch; they also serve as a fuel and for carbonization.

Industrial and craft applications:
Shells are processed into activated carbon for filtration and adsorption. The carbonized product is employed as a filtering medium for gases and water; granular shell chars are used in waste gas/wastewater treatment. Shells are also burned as fuel and utilized as horticultural mulch and in abrasives for polishing.

Food and beverages (non-medicinal):
Kernels are sold as in-shell or shelled nuts for direct consumption and ingredient use in confectionery, ice cream, pastries, and snacks. Brazil nut oil is produced by mechanical pressing for culinary use in dressings and light sautéing; solvent-extracted refining is commercially practiced for flavor-neutral oil suitable for larger-scale applications. Kernel and oil are regulated as foods under national legislation.

Colorants and tanning:
Shells yield brown natural dyes for protein fibers (e.g., wool, silk). Shells and husk contain tannins used for tanning leather. Studies report shells yield brown dyes suitable for natural-fiber dyeing, and the shells/husk are effective tannins for leather tanning.

Wood and fiber:
The wood is dense, durable, and suitable for flooring, carpentry, and construction. Use is limited by conservation concerns and restricted access; sustainable management plans govern legal timber flow. There are no documented non-wood fiber uses for this species.

Fragrance and cosmetics:
Brazil nut oil is used in cosmetic formulations for hair and skin products; it is supplied by food-grade nut processors to cosmetics manufacturers. No essential oil or volatile-fragrance uses are reported for this taxon.

Properties relevant to use:
Kernels have high oil content and produce a fixed oil with fatty-acid composition suitable for edible and cosmetic uses; refining yields neutral flavors. Shells are dense, lignocellulosic, and suitable for activation to produce high-surface-area carbon with effective adsorption performance. Shell tannin extracts show crosslinking and protein-binding properties useful in leather tanning.

Standards and regulation:
Brazil nut kernels and oil are subject to national food safety and labeling standards. Activated carbon from shells follows conventional activated-carbon specifications for iodine number, methylene blue adsorption, and moisture/ash limits (common ASTM D5463; ISO 13503). Timber use is regulated under national forestry codes and CITES/Directions for forest product trade depending on national listing.

Sustainability and sourcing:
Seeds are wild-harvested from natural forests, with production concentrated in Bolivia, Brazil, and Peru. Populations are vulnerable to habitat loss and overharvest, and market access is often linked to forest conservation through certified schemes and biodiversity-friendly production. Sustainable harvest guidelines and community-based forest management are emphasized to maintain long-term yield and ecosystem integrity.
