September 8–10, 2026 · China International Exhibition Centre
CIOF 2026 is presented as the 37th China International Optics Fair and is scheduled for September 8–10, 2026 in Beijing, China. The venue indicated on the official event page is China International Exhibition Centre, which is a practical advantage for professional visitors because it allows a concentrated three-day agenda focused on meetings, sourcing and technical validation. For importers, distributors and retail buyers, this format typically supports a structured procurement workflow: screening suppliers by product category, clarifying manufacturing capability and compliance readiness, then moving to RFQ-ready discussions with a shortlist. Because optics procurement is specification-driven, the event is most useful when visitors come with defined requirements for materials, coatings, tolerances, packaging and documentation, so that negotiations on pricing and lead times are grounded in clear technical parameters.
