Shock involving eastern goods (7)
I believe the answer is:
freight
'goods' is the definition.
(freight is a kind of goods)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for freight that I've seen before include "Goods carried by a large vehicle" , "Something carried" , "Consignment" , "Transport of bulk goods" , "that's carried by rail and road" .)
