In September 2024, the Ministry of Finance of Ukraine published an order defining the procedure for customs clearance of biomethane transported by pipeline. Effectively, this allows the export of biomethane to begin. For export, it is necessary to submit a periodic customs declaration; certificate of compliance with biomethane sustainability criteria; documents confirming the connection of the biomethane producer to the gas transportation or gas distribution systems; the act of receiving and transferring produced biomethane; and the act of the gas storage operator of Ukraine.
The following documents must be submitted after the physical export: an additional declaration with accurate information on biomethane amount; proof of sustainability of biomethane; general act of acceptance and transfer – a document signed by the operators of the gas transportation system of Ukraine and neighbouring countries; certificate of the GTS Operator regarding the accounting of commercial gas supplies and withdrawals.
