If you did an origin trip you could so sampling while in the origin country, then if the timimg was right you could order directly. In Indonesia it can be a wee bit difficult, as we have so many origins and the crop/harvest times are all over the place.
Probably best thing to do would be to send it freight back to the USA. Use a reputable freight forwarder at origin. You will need to complete the FDA requirements before shipping, but it is only time consuming, not too difficult otherwise. A reputable forwarder is important, because unless you are sending a FCL (18metric tonns) of coffee back, it means you will share a container with other shippers. Shipping manifests for all the shippers are couriered to US Homeland Security by the steam ship line. Any descrepencies with someone elses paperwork, means your greens will also end up being put into the container holding pen in Longbeach, Seattle, San Fran etc. Demurrage and costs for doing a full search on a container are bourne by shipping parties, not the forwarder or the steamship line. If you decide to ship out of Indo, I am more than happy to help you with the paperwork and shipping side of things...learnt in some cases by not so pleasant experience!
