The Attorney General shall register an applicant to import or export a controlled substance in schedule I or II if he determines that such registration is consistent with the public interest and with United States obligations under international treaties, conventions, or protocols in effect on May 1, 1971. In determining the public interest, the factors enumerated in paragraph (1) through (6) of section 823(a) of this title shall be considered.
No registration shall be issued under this subchapter for a period in excess of one year. Unless the regulations of the Attorney General otherwise provide, sections 822(f), 825, 827, and 830 of this title shall apply to persons registered under this section to the same extent such sections apply to persons registered under section 823 of this title.
Persons registered by the Attorney General under this section to import or export controlled substances or list I chemicals may import or export (and for the purpose of so importing or exporting, may possess) such substances to the extent authorized by their registration and in conformity with the other provisions of this subchapter and subchapter I.
Except in emergency situations as described in section 952(a)(2)(A) of this title, prior to issuing a registration under this section to a bulk manufacturer of a controlled substance in schedule I or II, and prior to issuing a regulation under section 952(a) of this title authorizing the importation of such a substance, the Attorney General shall give manufacturers holding registrations for the bulk manufacture of the substance an opportunity for a hearing.
