Cancellation policy

We hope you will join us at SPNHC-TDWG 2024 in person and online! However we recognize that unexpected changes occur. At any time, we encourage in-person delegates who are unable to travel to switch to be a virtual delegate.


Cancellation up to 16 August, 23:59 JST (UTC+9): cancellations for in-person attendance will receive a full refund, less fees, excursions (which must be booked and cancelled separately), and T-shirts. Fees retained may include transaction and exchange fees, plus printing and food services.

Cancellations between 17 August, 00:00 JST and 30 August, 16:59 JST (UTC+9), will be refunded at the rate of 50%, excluding excursions and tours.

Cancellations after 30 August, 17:00 JST (UTC+9), for in person attendance: no refund. In-person delegates who are unable to travel at the last minute will be automatically switched to be a virtual delegate.

Other fees retained will support the subsidies we have offered to students and our colleagues from low and lower-middle income economies.

In-person no-shows with no correspondence will not be refunded.

For alterations or cancellations to your registration please notify the SPNHC-TDWG Organizing Committee via email,
