You may “import” into the Russian Federation up to $10,000 (or equivalent) and “export” up to $3,000 without declaring it at the customs. If you export from the country a sum of money over $3,000 and up to $10,000 it must be declared upon departure.
If you are exporting from the country a sum of over $10,000 you must provide documentary proof that you either imported it into the country or have legally obtained it whilst in the country.
If you complete a declaration form to state that you are bringing in more than $3,000 you must ensure that it is stamped by a Customs official at your port of entry or it will not be valid. Declaration forms are freely available at the ports of entry.
If you cash travellers cheques, or obtain money from a bank, make sure you keep all documents as proof. Please note, that travellers cheques may be difficult to cash and be charged at a premium, outside of Moscow and St. Petersburg. Sterling may also be difficult to change so we recommend you take either US dollars or Euros.
NOTE! If you fail to complete a declaration form on arrival or to get it validated by Customs officials your foreign currency and non-declared items may be confiscated when you leave Russia and you may be fined.
