Hello,
Thank you for your question.
The classification process is entirely manual at this point.
We are working on a more automated approach, but that will not be ready until January 2017.
We have an upcoming release scheduled for September 1, 2016 that will include a more detailed JSON response with detailed information regarding taxes and fees.
If you have any additional questions, please email us at info@vineglobal.com
Regards,
