OSAC will not ship specimens to researchers or institutions in countries where import/export laws or regional postal services are perceived as risks to the specimens and/or their return. Researchers in these countries are encouraged to visit OSAC directly or make arrangements with another institution at which they might receive/return specimens.
Any specimens sent internationally must comply to international, regional and the carrier regulations for shipping scientific specimens.
For specimens preserved in ethanol, loanees should re-package their specimens for return according to IATA regulations: As of Feb 2014 those standards/regulation can be found here: OSU Shipping Guidelines - Feb 2014
ALL international shipments of museum specimens must be shipped with a US Fish & Wildlife 3-177 form. That form, and instructions for filling it out can be found here: http://www.fws.gov/le/declaration-form-3-177.html
