Dear Mr. Brown:

This is in response to your letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Specifically you ask whether a shipment intended for international transportation qualifies for domestic exceptions from the HMR.  In addition, you asked whether a shipment being prepared for transportation by highway in Mexico for delivery to the US may take advantage of the exceptions in the HMR prior to entering the US.

A shipment being prepared for transportation by highway in the US for delivery to a foreign destination may take advantage of any domestic exceptions including domestic proper shipping names and placarding.  This is true regardless of the destination.  However, when preparing a shipment of hazardous materials in a foreign country, it must comply with that country's regulations.  A shipment qualifies for the exceptions from the HMR only after entering the US.

I hope this information is helpful.
