A significant regulatory shift is underway: BIS Quality-Control Orders taking effect in April 2026 require manufacturers to obtain ISI marks. Analysts expect this to remove a large share of non-compliant supply — good news for quality-focused members.
What it means for the fraternity
- Greater assurance of product quality for clients and applicators
- Short-term price firming as non-compliant supply exits
- A level playing field that rewards compliant manufacturers
- Stronger grounds for specifications and warranties
TWA encourages members to source ISI-marked, standardized products and to update specifications accordingly.
