But beside, we also need the document from the chemical produce to have licence to import it. About shipping, did you ask the company that we sent sample for you last time? I hope maybe they have experience. This is food additive and if we have license, I think everything will be ok
運送の件ですが、貴社にサンプル送った時の船会社に連絡しましたか。その会社は経験があるかもしれません。
これは食品用の添加物なのでライセンスがあれば、大丈夫と思います。
