Title 27 - Alcohol, Tobacco Products and Firearms
(a) Testing. Proprietors shall ensure that the materials they receive for use in denaturing conform to the specifications prescribed in 27 CFR part 21. The appropriate TTB officer may require the testing of denaturants at any time. (b) Samples. Samples of denaturants shall be taken in such manner as to represent a true composite of the total lot being sampled. When samples are tested by persons other than a proprietor, a copy of the analysis or a statement, signed by the chemist performing the test, shall be secured and filed by the proprietor for each test. Samples of denaturants may be taken by appropriate TTB officers at any time for testing by Government chemists. (c) Conformity. When a denaturant does not conform to the specifications prescribed under 27 CFR part 21, the proprietor shall not use the material unless he treats or manipulates the denaturant to make it conform to such specifications. Such treated or manipulated denaturant shall again be tested. (Sec. 201, Pub. L. 85–859, 72 Stat. 1369, as amended (26 U.S.C. 5242))
