[July-Sept. 
shall permit entry into the United States insofar as these regulations may 
govern. The inspector may authorize temporary entry of railway cars under 
conditions to be prescribed by him for unloading or loading in railroad yards 
at the port of entry or for in-transit movement from and to Mexico. 
§ 320.6. Vehicles, articles, and materials, other than railway cars and unregu- 
lated boats. — When the inspector has determined by examination that vehicles, 
other than railway cars and unregulated boats, or any of the various articles 
and materials covered by these regulations may enter the United States without 
risk of introducing insect pests or plant diseases, he shall permit their entry 
insofar as these regulations may govern. If the examination by the inspector 
discloses such regulated vehicles, articles, or materials are contaminated and 
would involve risk of introducing insect pests or plant diseases into the United 
States, he shall prescribe, as a condition of entry, cleaning, transfer of cargo, 
or disinfection, or any or all of these. The cleaning, transfer of cargo and 
disinfection shall be carried out under his supervision and to his satisfaction 
and until it has been so accomplished' entry into the United States shall be 
refused. 
§320.7. Responsibility for opening and cleaning. — The owner or agent in 
charge of railway cars, other vehicles, and freight, express, baggage, articles, 
or other materials shall open these for inspection as required by the inspector 
and provide reasonable access to every part thereof, and when cleaning is 
prescribed by the inspector as a condition of entry, shall so open, and clean, 
and do any and all things reasonably pertaining thereto as required by the 
inspector. All costs incident to entry, opening, and cleaning, except for the 
services of the inspector, shall be paid by the owner or agent in charge. 
§ 320.8. Responsibility for disinfection. — When disinfection involves fumiga- 
tion the inspector will apply the fumigant whether in the houses erected for 
the purpose or in the cars themselves. If, in the judgment of the inspector, 
fumigation will not provide adequate safeguards against the introduction of 
insect pests and plant diseases, he may prescribe another type of disinfection 
which shall be applied by the owner or agent under the supervision of the 
inspector. Costs incident to such disinfection, other than the services of the 
inspector, shall be borne by the owner or his agent, or paid for as prescribed 
elsewhere in these regulations. 
§ 320.9. Fees for disinfection in government-owned facilities. — Prior to entry 
of railway cars or other vehicles requiring fumigation in government-owned 
facilities as a condition of entry, the owner or agent in charge shall buy fumiga- 
tion coupons from the inspector in charge at the port of entry. The price 
fixed for these coupons shall represent as nearly as may be, the average cost 
of materials, facilities, and special labor used by the Bureau of Entomology 
and Plant Quarantine in performing such fumigation. On the basis of the 
average cost for such fumigation over a period of years the inspector in charge 
shall, until further notice, collect a fee of $4.00 for each coupon sold. Payments 
for coupons, if practicable, shall be in the form of postal money orders, or bank 
drafts or certified checks drawn on United States banks, drawn to the credit 
of the Treasurer of the United States. Payments in United States currency 
will be accepted if tendered. All fees so collected by the inspector shall be 
promptly turned into the Treasury of the United States as miscellaneous receipts 
in accordance with the practices approved by the Secretary of Agriculture. 
These regulations shall supersede the Rules and Regulations Prohibiting the 
Movement of Cotton and Cottonseed from Mexico into the United States and 
Governing the Entry into the United States of Railway Cars and Other Vehicles, 
Freight, Express, Baggage, or Other Materials from Mexico at Border Points,
