According to the National Iranian Oil Company, companies can apply from Sunday through Tuesday, Feb. 10, via the registration system on the exhibition’s website at www.iran-oilshow.ir.

Initial pre-registration does not constitute final approval. Applicants will be reviewed and verified, and final acceptance will be issued by the event’s technical evaluation committee in line with announced criteria and available exhibition space.

Organizers said that in line with decisions by the policymaking council and a new approach emphasizing innovative and technology-based firms, applicants may include relevant explanations during the pre-registration process.

The 30th edition of the exhibition is scheduled to be held in May 2026 at Tehran’s Permanent International Fairgrounds.
