While we provide customs with all the proper documentation, we have no way of knowing if it will pass through the customs of your particular country without being held up. We encourage you to investigate your countries rules and regulations RE: importation of your order and the exportation of your specimens if you are testing. PCI will not be held responsible for any costs associated with customs. If you should have any specific questions about the country you live in, you can use the Contact us link at the bottom right of this page or click here CONTACT US.
