The board tweeted a photo of the delegation with the message: “Ukrainian Paralympic team together earlier today before climbing to #Beijing 2022.”
IPC refused to share the authorization location for security reasons.
Ukrainian athletes will compete at the Beijing Olympics in two sports: biathlon and cross-country skiing.
Ukraine won 22 medals at the Pyeongchang Games four years ago, and all of its seven gold medals came in the above disciplines.
Meanwhile, a decision on whether or not to ban Russian athletes will be made at the IPC’s board meeting in Beijing on Wednesday.
The governing bodies have so far suspended Russian teams from competition or stripped the country of the right to host the events.
Russian athletes will compete under the Russian Neutral Paralympic Committee (RPC) banner following the historic 2020 state-sponsored doping ban.
According to the IPC, the majority of the 71 athletes scheduled to visit Beijing will be in the Chinese capital on Tuesday.
The Beijing 2022 Paralympic Games kick off with the opening ceremony on Friday before the official competition begins on Saturday.
