Potential upsell: expanded testing services, additional pollutants, and certification support for new biomass products.

Transparency Focus Positioning around transparent testing services and customer-friendly features suggests opportunities to sell reporting dashboards, data access tooling, and audit-ready documentation packages to manufacturers seeking clear compliance trails.
