What does 已出口直封 mean?
I guess this should mean the inspection was successful and your package is directly(直)  (re)packaged(封)

According to http://community.ebay.cn/thread-1200132963-1-1.html (this is the most helpful page I have found)
A translation is "departure from outward office of exchange". A Chinese explanation is "这表示包裹己经顺利的通过海关检查,重新打包好,交给航空公司,等待航班飞走", it means "this indicates the package passed the inspection by custom and had been repackaged, sent to airline and waiting the plane to fly"
