According to now we’ve contacted Thai customs officer to discuss about the exact H.S. code of RAV7AT, due to we need to apply H.S. code 292090.90 (Tax 0%).
However after we apply document of registration letter & certificated of analysis (RAV-7AT) to Thai customs, we were informed that there are inconsistency between these two document as follows,
The detail on registration letter stated that RAV-7AT contain only “Diethyleneglycol bis (allylcabonate)” CAS # 142-22-3, total 100% however the detail on certificated of analysis stated that there are impurity substances (ADC, AD2C & AD3C content) in RAV-7AT.
Thus please help to explain why the information on chemical composition sheet do not declare impurity substances.
In addition, they request us to provide chemical structure of ADC AD2C & AD3C. Therefore please help to provide this information too.
We look forward to hearing from you soon.
