Problems with US Customs HELP!

[Frank Farruggia]

Recently we have requested herbarium specimens from England, which were then
sent via DHL.  Last week we were informed that US Customs had "quarantined"
the materials and were holding them till approval was received.  Its been a
week and we have no new information.  Do any of you know how to resolve this
issue?  Who do we contact?

Thanks
Frank
