I am in the Philippines and sending my DJI Osmo to my son in the USA for use on a school project. It will be sent back to me after his use.
Our local FedEX is asking me to fill out the FCC 740 form.
The FCC ID is on the box but where do I find the Harmonized Tariff Number?
Thanks!

It's about customs clearance issue. Can you find relative staff who's working on it and ask for help?
