Shipping

[Stinkfist]

Actualy the mail will accept yeast samples, heck at work we recieve hiv, flu, salmonella, and some other nice nasty bacteria and viruses though the mail. The key though is you have to ship it properly, meaning your price goes up and theres a lot more rules and regulations. To ship it you would have to class it as a UN item, id guess UN3373 which is biological substance catagory B. By using this i dont see why you cant ship "yeast samples" by mail, and in practice it is the proper way to ship. The issue is if you are shipping it this way they can require you to disclose what your sending which you could then probably use the name of your yeast/bugs but make sure you go to the leagle weight limit on the amount you declare so your volume isnt questioned.

If my memory is actualy correct i think we got a fungus though us mail a few weeks ago.

But Fedex and UPS is much less hassel but still could give you just as much greif.

Alcohol is strictly prohibited to send through usps no matter how you send it, Unless of course you have a license to do so......all those other things you listed are not alcohol....it is probably an antiquated law but it is still there...

USPS publication 52 section 42. Intoxicating liquors having 0.5 percent or more alcoholic content are nonmailable. This includes taxable liquors with 3.2 percent or less alcohol, as well as those obtained under a prescription or as a collector's item. The prohibition of the mailing of intoxicating liquors is contained in Federal law 18 U.S.C. 1716.
There is an exemption when it is sent between employees of federal or state agencies who have an official use for the liquor, such as for testing purposes. This exemption is based on the intent of the law to prevent liquor from being transported to prohibited jurisdictions for consumption and to ensure that all proper tax revenues are paid.
