Draft for legal review – the approved text replaces this summary before launch.

Support is available in English and Chinese. Signed-in users contact support from Messages in their account, so the request is linked to the right organisation.

For an Export Readiness Assessment, send your request the same way; VTRIN operations open a case and send you an offer.
