I-68 has been in use elsewhere around the country, but not in the Pac
NW until now.

Customs seems to be set up something like CG districts....the general
rules apply everywhere but some of the details can vary from region to
region.

The Customs officer who provided the information from which I
constructed the report noted that the I-68 requirement can't be phased
in until they actually receive the forms and train the local customs
examiners in this region.
