SA115-C 

Export Control Policy 

When applying a refrigerator to a cryocooler for optical sensors, the 
cryocooler falls under row 6.A.2.d.2 of the control list established by 
The Wassenaar Arrangement, which is equal to row 10(2) of 
appended table 1 of Japan’s Export Trade Control Order. 
Customers must follow all related rules and regulations  such as 
Foreign Exchange and Foreign Trade Act and take  appropriate 
procedures when exporting or re-exporting our refrigerators.
