I have an online business and ship product all over the world. I received an order from a company in Nigeria(IBISAM NIGERIA LIMITED) that totaled $1360 including shipping costs. The company sent me a company check that had City Bank New York indicated as the US corriespondant bank. I deposted the check approximately 35 days ago but have been reluctant to ship the produc t. To date the check has not been returned. At what point can I consider this to be a legitimate transaction. The customer PO is very detailed and appears legitimate. I have received several e-mails and phone calls inquiring as to when the goods would be shipped. Is there a statute of limitations on returned checks. My biggest fear is that they will get my product and promptly initiate a chargeback claiming the check was a forgery. Any advice would be appreciated.
