Common products:
- Sawn hardwood timber (heartwood) used in construction, furniture and joinery.
- Small-diameter stems and branches supplied as fuelwood and for charcoal production.
- Bark harvested for extraction of tannins employed in leather tanning.
- The heartwood is prized for its attractive grain and is used in interior paneling.

Industrial and craft applications:
- The durable hardwood serves as structural material in heavy construction (bridge timbers, railway sleepers) and in interior and exterior joinery.
- Bark tannins are used in the leather industry as a natural vegetable tanning agent.
- The wood fiber can be processed into kraft pulp for paper manufacture.

Colorants and tanning:
- Bark yields a brown natural dye historically applied to wool and silk.
- The tannin‑rich bark is the basis for vegetable tanning of hides and skins.

Wood and fiber:
- The timber is a dense, strong hardwood with good dimensional stability.
- Wood fibers have a relatively high cellulose content, suitable for pulping processes.

Properties relevant to use:
- High specific gravity, providing good mechanical strength for structural uses.
- Natural extractives (flavonoids and phenolics) confer resistance to decay and insect attack.
- Bark contains a high proportion of hydrolysable tannins (gallotannins and ellagitannins), enabling efficient leather tanning.
- The wood’s low shrinkage upon drying reduces warping in finished products.

Standards and regulation:
- Sawn timber is classified under the International Trade Classification (HS 4407) and may be tested according to ISO 13061 for density and strength.
- Tannin extracts follow national food‑grade or cosmetic regulations where applicable (e.g., EU Regulation 1223/2009 for cosmetic ingredients).
- National forestry codes in Ghana and Côte d’Ivoire govern harvesting, transport and export of the species.
- Export of processed timber requires phytosanitary certification under the International Plant Protection Convention (IPPC).

Sustainability and sourcing:
- Anonychium africanum is harvested from natural forests in West Africa; no large‑scale plantations exist.
- Sustainable management recommendations include selective logging, regeneration surveys and monitoring of population levels; the species is currently not listed as threatened.
- The species is classified as Least Concern on the IUCN Red List, and national forest authorities recommend sustainable harvest rates with regeneration monitoring.
