Air transport packaging of polysilazane

When transporting organopolysilazanes, we often encounter many problems.

Such as: How to choose the HS code?

which category of dangerous goods does it belong to?

What are the requirements for air freight packaging?

Appearance	Colorless, transparent to light yellow liquid
Applications	Industrial coatings Adhesives, ceramic precursors Composites and coatings
Hazard Description	Highly flammable liquid and vapor Harmful if swallowed Damage to eyes
HS code	3911900090
UN number	UN2920/8/3/II

We usually use passenger aircraft for delivery. The delivery standard of passenger aircraft is: 1L/plastic bottle, 1 bottle/UN box.

First, we will use aluminum bottles to package polysilazane. Because of the nature of aluminum materials, it can be packaged and transported safely to a great extent.

Secondly, we put a bag into the box, and then put a small amount of sawdust at the bottom of the bag. After putting the bottles in, we will put a layer of foam on top. This will maximize the safety of the packaging during transportation.

Finally, we use packaging boxes that are certified by an international certification body (dangerous goods packaging certification).

Finally, we will pack the goods on pallets according to the quantity.
