The 1994 Paris Protocol governing Palestinian Authority (PA)-Israeli economic relations provides that the PA not impose tariffs on goods of Israeli origin, although the PA does impose purchase taxes on many durable goods imported from other countries, generally at Israeli rates. All West Bank and Gaza-bound imports that enter through Israeli ports are assessed a 17% VAT as a customs fee. This amount is transferred to the PA as a VAT of 16% on all goods sold in the West Bank and Gaza. The 1% difference is eventually rebated to Palestinian importers via the PA, at times after long delays.
