The European Union has granted the Generalized Scheme of Preferences (GSP) Plus status to Pakistan in December 2013. This status is likely to increase access to the EU market through duty free imports of GSP-eligible products. The grant of the GSP Plus status is effective from January 1, 2014 & by its implementation Denim will be duty free for EU countries.
The “GSP+” enhanced preferences means full removal of tariffs on essentially the same product categories as those covered by the general arrangement. (According to European Commission/Trade). EU’s “Generalized Scheme of Preferences” (GSP) allows developing country exporters to pay lower duties on their exports to the EU. This gives them vital access to EU markets and contributes to their economic growth.
