Dear Mr. Pstrak:

This responds to your letter of April 7, 2005, requesting clarification as to whether a shipper that has drilled holes in a “Type A package” must perform an analysis on the package to confirm that no contents would be released.

The answer is yes. It is the opinion of this office that if holes are drilled in a package that was previously demonstrated to satisfy the “Type A package” performance requirements, the package would no longer be identical to the previously designed and tested package. Therefore, a “Type A package” that has holes drilled in it, may not continue to be designated as a “Type A package” until it has been completely evaluated against the specifications specified in § 178.350. That evaluation may be conducted using any of the methods described in § 173.461(a), or a combination of them, and documented in accordance with § 173.415(a).

I trust this satisfies your inquiry. If we can be of further assistance, please contact us.
