and parcel-post packages containing live plants, propagating material, cotton 
lint, and other materials subject to quarantine regulations must be accom- 
panied by foreign official certificates issued at points of shipment when such 
products originate in countries that maintain government quarantine or plant 
protection services. Such certificates must aflSrm that the shipment in 
question : 
(a) Is entirely free from infestation by the quarantine pests named in the 
permit. 
(&) Or that the organization that issued the certificate does not guarantee 
the absence of infestation by those insects and diseases. 
GROUP 1

hibition of the importation of products likely to be the means of introducing 
them into the Union of Soviet Socialist Republics when proceeding from in- 
fected countries. Exception is made only with respect to specimens for scien- 
tific purposes, the importation of which into the Union of Soviet Socialist 
Republics is. in each instance, subject to a permit from the Bureau of Foreign
