is an interesting question. My instinct is that as it is not for
sale IN the UK, despite being available TO the UK that there is no
obligation on you at all to hallmark it, I can't see why or how
that would need to happen. But you could always email the assay
office (via the link above) - they are very friendly and helpful.
You are not a UK maker, so this wouldn't apply to you I don't think
- just to the importer. but you could check. It would be interesting
If someone in the UK or any of the convention countries buys your
unhallmarked work and brings it into the UK as personal property you
are under no obligation to deal with the issues of assay and
hallmark. If a dealer buys the work for resale, it is up to them to
comply with the laws. That can mean that either they have it assayed
or you do it, either is OK as long as it is done. It is the retailer
that takes the heat if it is not done, not the maker.
My experience is that when I offer to have the piece hallmarked for a
UK retail customer and explain the expense and delay, they have
always declined. My several UK wholesale customers insist on
hallmarks, so I am registered. But it remains a barrier to trade
since it is very inconvenient and also adds expense and delays.
