Horizon, along with Al Cumings and UGA, was solely responsible for the investment and 4 years of battles, finally getting the USPS to start mailing live birds back in 1989.
We also helped push FedEx to accept live birds for the USPS in late 2006 just before the USPS was about to turn it completely off, 
helping hundreds of small businesses stay in business. We remain dedicated to being your voice in mailing live birds thru the USPS.

Live Bird Shippers for the US Postal Service

The illustration below is WHY our containers are designed a little bit more complicated
than our competitor's boxes. Air circulation should not be an option.

.Horizon makes USPS/FedEx, USDA, and IATA approved shipping boxes for live birds. That's it. That's all we do. But we do it great! We started it!

We are the largest developer and manufacturer of universally approved, environmentally-secure shipping containers for live birds, designed primarily for the U.S. Post Office's  Express Mail service. 

All of our shippers meet and exceed all the ASTM Project 1A standards and have always gone the extra mile to have all our containers officially approved by USPS headquarters.  No other manufacturer of  shipping containers can make this claim.

Unlike our competitors, we test our containers extensively for any heat build-up and ventilation flow problems that will occur in planes, especially with double-stack designs.
