Title 27 - Alcohol, Tobacco Products and Firearms
(a) General. (1) Pipelines for the conveyance of spirits, denatured spirits, articles, or wines shall be of permanent character and constructed, connected, arranged, and secured so as to afford adequate protection to the revenue and to permit ready examination. However, the appropriate TTB officer may approve pipelines which may not be readily examined if no jeopardy to the revenue is created. (2) Where a pipeline connection must be flexible, a hose may be used if connected and secured so as to protect the revenue. (b) Identification. The appropriate TTB officer may require permanent pipelines for conveyance of spirits or denatured spirits to be color coded to provide identification. (Sec. 201, Pub.
