Material distinction: fumigation-free wooden cases and fumigation wooden cases are made of fumigation-free multi-layer plywood, and the difference lies in the bottom support and side strips. The edge of the fumigation wooden box is solid wood, mostly white pine, and the bottom is also solid wood, mostly poplar; The edge of the fumigation-free wooden box is made of laminated veneer lumber, which is a high-density composite compression board. Because it is fumigated during processing, it has the characteristics of direct export, and the base is also made of it.

Time division: after the fumigation of wooden cases is completed, the simple fumigation period should be at least two days, and the validity period is 2 1 day. 2 1 day before export; Fumigation-free wooden cases can be directly exported after processing, which has many advantages in time and no shelf life. No matter how long you leave them, you can export them directly. In other words, wooden cases with the same specifications can be exported when they are finished, while fumigation wooden cases can only be exported after fumigation with solid wood to achieve the effect of moth prevention;

Price differentiation: The production cost of fumigation wooden cases is often at least half as expensive as that of non-fumigation wooden cases, because there is a separate fumigation cost.

The raw material of the fumigation-free wooden box is composite board or plywood, and its board is formed by various wood scraps after high temperature and high pressure disinfection. The finished product will not contain insects and eggs, and the risk of introducing pests is very small, which will not cause harm to agriculture and forest resources. Therefore, when this wooden box is used as an export packing box, the customs department does not require fumigation.
