我想把磁性冰箱贴发到FBA，这个算是违禁品吗？

这个不清楚耶。我只在帮助里找到了这个：
Hazardous ＆ Dangerous Items

问一下客服比较好

谢谢楼上的回复。我是把磁铁装在冰箱贴里面（如图），买家是拆不开的：


 

那我觉得应该OK吧。因为主要的顾虑是安全问题，担心小孩子会不小心吞下去。如果冰箱贴足够大，那小孩就没法吞下去。
以前我有问过客服关于ceramic magnet的问题，他们是说磁铁的大小很重要：
"As long as the products comply with the following:Amazon policy requires that all strong magnets (for example, neodymium and rare earth) must be too large to fit inside a cylinder that is 1.25 inches diameter and 2.25 inches long. Then the items should have no problem. 
Size is very important since the material you have mention is ceramic Magnets.I'll suggest to avoid the word Batteries, since this could trigger an alert to the system."
