(a) Recovered denatured spirits and articles. A proprietor may receive recovered denatured spirits and recovered articles on bonded premises for restoration (including redistillation, if necessary), or redenaturation, or both, as provided in subpart Q of this part. However, the proprietor may not withdraw the spirits from bonded premises except for industrial use or after redenaturation.

(b) Spirits or articles retaining some denaturants. If recovered denatured spirits or recovered articles are to be redenatured and do not require the full amount of denaturants for redenaturation, the proprietor must make an entry to that effect in the record of denaturation required by § 19.606(b).
