原来托盘还有不同的种类，托盘还有需要熏蒸的，还有不需要熏蒸的。之所以需要熏蒸的托盘，是因为这样的托盘都是实木（原木）做成的托盘，所以就需要熏蒸并有熏蒸标识。 主要怕未经过处理的木质的托盘里面可能存在寄生的虫子或者有虫卵这样进入另一个国家会影响这个国家的生态平衡。严重的可能会影响农林业，可能会对此造成严重危害。所以才会必须要求熏蒸。记得前些年就发生过类似这样的事件。
There are different types of pallets, including those that need fumigation and those that do not need fumigation. The reason why the tray needs to be fumigated is that such trays are made of solid wood (log), so they need to be fumigated and have fumigation marks. The main fear is that there may be parasitic insects or eggs in untreated wooden trays, which will affect the ecological balance of another country. Serious may affect agriculture and forestry, which may cause serious harm. That's why we have to ask for fumigation. I remember something like this happened a few years ago.
