According to the Turkish Government Official Journal of 18th April (No. 31103 –2424) certain fasteners imported to Turkey will be subject to additional tariffs from that date.
The tariffs appear to be part of a wider programme of additional duties covering an extensive range of products. From 18th April to 30th September imports of what appears to be the majority of fastener classifications will be subject to an additional 30% customs tariff. This will take the total tariff for countries categorised ‘9’ by the Turkish Government, which include China, Taiwan and Japan, to 33.7%.
From 1st October, the additional tariff level adjusts to 10%, taking the Category 9 total to 13.7%.
