Code:
cat a.csv | sort > a.csv
cat b.csv | sort > b.csv
comm -23 a.csv b.csv > c.csv.

Code:
a.csv
SKU     COUNTRY     CURRENCY     PRICE_LIST_TYPE     LIST_PRICE_EFFECTIVE_DATE
TG430ZA    ZA    USD    DF    2012-03-28    9999-12-31    120000    
TG431ZA    ZA    USD    DF    2012-03-28    9999-12-31    96000    
TG432ZA    ZA    USD    DF    2012-03-28    9999-12-31    1200    
TG433ZA    ZA    USD    DF    2012-03-28    9999-12-31    12000

TG433ZA    ZA    USD    DF    2012-03-28    9999-12-31    12000
