These are very reasonable requirements .
These are just the requirements to claim treaty benefits . A little bit of research wouldn't hurt.
You have to fill out the Form-10f to claim treaty benefits for the reduction of withholding tax on services and royalties .
These are the requirements:
Tax Residency Certificate (TRC) (= extract from cantonal commercial register) • Non-Permanent Establishment Declaration (No PE Declaration) • Form 10F: If you are registered accordingly, Form 10F can be submitted online.

This is very unprofessional in my opinion how pocket base handled that issue as this is a perfectly reasonable request .
It's a similar to the W8-BEN non us resident aliens have to file .
