Your adherence to these standards is important for the church to maintain good relations with customs officials. If you wish to send a package to Russia or Ukraine, you may consider using a shipping firm. The Church does not recommend the shipping packages via the U.S. Postal Service to these countries. Many packages shipped this way never arrive at their destination. It is recommended that you ship through a private firm which guarantees reliable delivery.
Several firms have very reasonable prices and claim guaranteed delivery.
U.S. postal mail to some other nations in Eastern Europe is more reliable. Please check the guidelines for your country with the mission office if you have questions. If you have not received a letter from your missionary for some time, it could be for many reasons. Mail from Russia is slow and erratic. Sometimes mail sent sooner than another letter will arrive later.
