[Histonet] picric acid paranoia

[Tyrone Genade]

Hello,

I am moving to the USA from sunny South Africa. I would like to bring my
wax blocks with me but the fish inside them were fixed with Bouin's fluid.
I'm worried the picric acid could draw the wrong sort of attention. Courier
companies and US Customs (which never got back to me) haven't been able to
give me an answer if they are safe to travel. The blocks have sat under my
lab bench for 4 years without blowing up so I guess they are perfectly
safe. Anyone have an opinion on the issues or some advice on an expert (at
US customs?) to contact? I would probably ship them by surface post as it
just more cost effective.

Thanks
