NTE

What NTE does

NTE is a private South African manufacturing company headquartered in Pietermaritzburg that produces wattle tannin extracts and derivative chemicals from Black Wattle (Acacia mearnsii) bark. Its core commercial lines are the Mimosa range for leather tanning and retanning and the Bondtite range for composite wood, corrugated cardboard, mineral processing, water treatment, and animal nutrition. It sells to industrial buyers in natural leather, composite wood, water treatment, animal feeds, mineral processing, and corrugated cardboard, with customer activity described across five continents.

The company’s process extracts condensed tannins by counter-current extraction in pressurized autoclaves above 100°C, then concentrates the liquid extract through evaporation and sells it as solid or spray-dried powder. NTE also modifies tannin chemistry for application-specific performance, including Mimtan AT1 for reduced astringency and improved light-fastness and heat resistance, Bondtite adhesive and flotation products, SupleMim feed additive, and Lucent natural coagulant for water treatment.

NTE’s revenue model is B2B product sales rather than software or recurring subscription revenue. Pricing is not publicly disclosed and appears quote-based through direct sales, supported by technical support and long-term industrial customer relationships. Supply is tied to a grower-owner structure: NTE is owned by more than 700 wattle growers and manages 68,000 hectares of wattle plantations, linking raw bark sourcing to manufacturing.
