Just to be absolutely clear :

xa-s03:~# sg_inq -e -o=0x83 /dev/sdb
EVPD INQUIRY, page code=0x83:
 Only hex output supported
 00     00 83 00 14 01 03 00 10  60 05 08 b4 00 01 56 d7   
........`.....V.    
 10     00 01 20 00 00 0b 00 00                             ..
.....            

Here :
o opcode is 0x83
o evpd is set
o offset is 8 (wwid = 600508b4000156d700012000000b0000)
