Qg BUREAU OF ENTOMOLOGY AND PLANT QUARANTINE [April-June 
ANNOUNCEMENT RELATING TO RULES AND REGULATIONS GOVERN- 
ING THE IMPORTATION OF COTTON AND COTTON WRAPPINGS 
INTO THE UNITED STATES 
MODIFICATION OF COTTON REGULATIONS 
Amendment No. 4 of Rules and Regulations Governing the Importation op 
Cotton and Cotton Wrappings into the United States 
[Effective on and after July 1, 1938] 
introductory note 
The Cotton Regulations revised effective February 21, 1923, provided for the 
entry of cotton lint and cotton linters from Mexico via border ports only when 
they originated in the Imperial Valley of Baja California, Mexico. Effective 
December 15, 1924, the regulations were modified to provide for entry from other 
specified areas in Mexico through ports on the border. Since that date the 
Bureau has acquired a wider knowledge of pink bollworm control measures, and 
has been able, in connection with its administration of Quarantine No. 52, the 
domestic pink bollworm quarantine, to acquaint itself more thoroughly, through 
the cooperation of the Mexican Government, with the pink bollworm conditions 
in areas in Mexico adjacent to the border and with control measures carried on 
in such areas by the Ministry of Agriculture and Development of that country. . 
In the light of this wider knowledge a more liberal policy is adopted to allow 
the entry of baled cotton lint and linters from Mexico, subject to conditions of 
entry paralleling the conditions under which cotton lint and linters, produced in 
the pink bollworm infested areas of the United States, may move interstate under 
the provisions of Quarantine No. 52. 
Regulation 13 of the Cotton Regulations, as hereby amended, is predicated 
upon a continuance of the enforcement, in cotton-producing areas of Mexico, of 
measures of suppression and of measures to prevent the spread of the pink boll- 
worm which are deemed by the United States Department of Agriculture to be 
equal in effectiveness to measures enforced in cotton-producing areas of the 
United States having a similar status with respect to the pink bollworm. The 
importation of baled cotton lint and linters from Mexico, as provided in regula- 
tion 13, as amended, is further contingent upon the determination, from time to 
time, by manner and method deemed satisfactory to the Department, of the 
status of Mexican cotton-producing areas with respect to the pink bollworm 
and upon the determination, by manner and method deemed satisfactory to the 
Department, of suppression and control measures enforced in Mexican cotton- 
producing areas. 
Avery S. Hoyt, 
Acting Chief, Bureau of Entomology and Plant Quarantine. 
Under authority conferred by the Plant Quarantine Act of August 20, 1912 
(37 Stat. 315) as amended, it is ordered that regulation 13, of the Rules and 
Regulations Governing the Importation of Cotton and Cotton Wrappings into 
the United States, be, and the same is hereby, amended to read as follows: 
Regulation 13. Provision for the Entry via Boeder Ports of Cotton Lint 
and Linters From Mexico 
Baled cotton lint and linters produced in Mexico may be imported into pink 
bollworm infested areas of the United States through border ports approved by 
the Chief of the Bureau of Entomology and Plant Quarantine for that purpose, 
subject to such treatment on arrival as is required under the regulations of the 
domestic Pink Bollworm Quarantine No. 52, for the interstate movement of 
cotton lint and linters produced in those areas : Provided, however, That no 
cotton lint and linters produced in areas of Mexico determined by the Chief of 
the Bureau of Entomology and Plant Quarantine as heavily infested with the 
pink bollworm may enter the United States under the provisions of this 
regulation unless such areas are adjacent to heavily infested areas of the 
United States.
