Further, Limestone Technologies personnel will report to the U.S. Department of Commerce Enforcement Division any and all individuals or agencies who may attempt to do so.

Limestone Technologies has also implemented the following requirements to help ensure that our instrumentation is not illegally exported to any restricted countries and to become more familiar with our customer base. Orders for polygraph systems will not be accepted without first receiving a signed and dated, “U. S. Department of Commerce Polygraph Export Restriction Compliance Form” which requires the name(s) of the examiner(s) who will be using the system.

We apologize for any inconvenience this may cause you or your customers, but Limestone Technologies Inc. is committed to compliance with all U.S. export requirements and thus this policy is necessary.
