Export of Matrox Parhelia 128MB PH-A128 to Russia

Question posted by Jon Dane

We have advertised a Matrox Parhelia 128MB PH-A128 on eBay. This item was purchased in 2004 and is surplus to our needs. A Russian buyer has purchased the item on eBay and has paid by PayPal. Are there any restrictions or rules that we need to take into account before accepting this order?
