Think Its Possible To Order Tubes From the Ukraine?

Having a set of tube amps being shipped to me this week. Its a pair of Audio Mirror Reflections monoblocks that use the 6C33C tubes. The amps come with one set of outputs and a pair of spares. I was thinking of ordering a backup set of tubes. After looking at the tube sites, the majority of them are Russian sellers, and that is not going to work due to current events. However, there are sellers from the Ukraine of this tube. Do you think a person can order from them and have a good chance of receiving their package?
