Since COVID19 prevented onsite verification, remote verification (via web-based video conference calls, and telephone calls) was conducted in November 2021, February, and March 2022. The assurance encompassed IVL Dhunseri Petrochem Industries – Haldia (PET) located in India; Indorama Petrochem (PTA) located in Thailand; Indorama Ventures Polymers Mexico (PET & Fibers) located in Mexico, Indorama Ventures Oxides Australia (IOD) located in Australia and Auriga Polymers (PET & Fibers) located in USA. The assurance activities were done together with a desk review carried out for all other IVL sites within the reporting boundary. Applicable boundaries for disclosures are explained in the Report. Limitations TUVI did not perform any assurance procedures on the prospective information, such as targets, expectations, and ambitions, disclosed in the Report.
