1. UN certificate- kindly provide a copy for verification As previously advised that we are on the process of renew the license, once we have it in next three weeks, I would definitely share with you.
2. What is the material of the bottle? HDPE? The bottle is HDPE
3. There is a sealing pad within the bottle cap (See attached picture). What material is that? We just want to make sure that it is compatible with the chemicals we are working on. the sealing pad is Teflon.
You should have sample of the bottle soon.
Again, sorry for my delay respond.
