Before finding a substance to be a narcotic precursor, the Commissioner shall give due notice in the FEDERAL REGISTER and afford an opportunity for public hearing to interested persons.

(b) Requirements as to persons engaging in transactions with respect to narcotic precursors. Any person who is engaged in the manufacture, compounding, packaging, selling, dealing in or giving away of a narcotic precursor, as defined in paragraph (a) of this section, shall:

(1) Maintain records as prescribed in paragraph (d) of this section; and

(2) Prepare and submit an annual report on Bureau Form 193 on or before February 15 of each year.

(c) Exception to applicability of paragraph (b). The provisions of paragraph (b) of this section shall not apply to a person manufacturing a narcotic precursor who holds a license to manufacture a basic class of narcotic drug under section 8 of the Narcotics Manufacturing Act of 1960, provided that the narcotic precursor manufactured by such licensee is to be used exclusively by him for the manufacture of the basic class of narcotic drug for which he holds a license.

(d) Procedure as to maintenance of records and preparation of annual report. The manufacturer of a substance which has been declared a narcotic precursor shall keep for a period of not less than two years such records as will enable him to supply the Commissioner accurate information as to the quantity of such precursor manufactured or otherwise acquired by him, his dispositions thereof, the names and addresses of the persons to whom supplied, the quantity supplied to each and the use for which intended. The annual report on Form 193 shall include a summary of this information for the calendar year.

IMPORTATION OF NARCOTIC DRUGS

§ 307.151 Importation of narcotic drugs for scientific purposes.

(a) Exemption for scientific purposes. Notwithstanding the provisions of § 302.1 of this chapter, the Commissioner of Narcotics may issue a formal permit to certain classes of persons desiring to import any narcotic drug or drugs (including crude opium and coca leaves) for scientific purposes only.

(b) Application for import permit. Application for a permit to import shall

be made to the Commissioner on Bureau Form 191. The applicant for such import permit shall also prepare and submit to the Commissioner, Bureau Form 185 (Drug Identification Sheet), where the substance to be imported is a narcotic drug not described in the standard reference works on drugs and chemicals.

(c) Limitation on authorization to import. Imports under this section will be limited to narcotic drugs not readily available to the applicant from sources within the United States, unless questions of origin, types or particular methods of production are elements of the research objectives. Each importation desired must be separately applied for and be covered by a separate import permit. Applicants for import permits licensed under section 8 of the Narcotics Manufacturing Act of 1960, who as part of their manufacturing business maintain branch or subsidiary manufacturing establishments in foreign countries, or are themselves a branch or subsidiary of a foreign parent organization, may be issued import permits for occasional imports of samples of the products of these foreign branches, subsidiaries or parent organizations for the purpose of research or spot check analyses to establish or maintain proper chemical and therapeutical standards of their products. However, an applicant will not be granted import permits to make continuous or regular imports of samples of recurring batches or lots of the same product for routine factory controls.

(d) Disposition. All drugs imported under this section shall be used in research or otherwise disposed of as authorized by the Commissioner, within five years from the date of their import, unless an extension of time for completion of the research has been granted by the Commissioner.

(e) Reports. Persons importing narcotic drugs under this section shall render to the Commissioner semi-annual reports on Bureau Form 192, as of June 30 and December 31 of each year, to be submitted not later than the 15th of the month following, accounting for the importation and use or other disposition of the narcotic drug or drugs so imported.
