Every seller located in North America agrees to the following statement before their listing goes live: I agree that the hops being listed have already been processed, are available for immediate shipment, are completely sealed (unopened boxes, no punctures) in original packaging, and have been stored cold. This is a legally binding contract between buyer and seller. Sellers are reviewed by a peer rating system (you can click on any seller's profile to see their reviews/history). 

Cold storage is not a requirement for sellers outside of North America because refrigeration of hops is not as common elsewhere. You can always use the orange Ask the seller a question button on any listing details page to get more information about a given listing. We are considering adding refrigeration and/or storage temperature as a required field for new listings. If you like/hate that idea or have suggestions for changes/improvements, please post them to the LEx Community.
