The UK has decided to ban trade in goods and services from illegal Israeli settlements in the Occupied Palestinian Territories. This move is meant to align with international law, but it raises questions about how effectively it can be enforced. Similar to the Kimberley Process, which aims to stop the trade in "blood diamonds" mined using forced labor, enforcing this ban may be difficult, especially for agricultural products like dates and olives, where it is hard to trace the exact origin of the goods. The Foreign, Commonwealth and Development Office (FCDO) has previously raised concerns about the practicality of such sanctions. One challenge is the difficulty in clearly distinguishing between areas that are internationally recognized as part of Israel and those that are considered occupied Palestinian territory. Since 2005, the UK has already restricted preferential tariff treatment for products from Israeli settlements in the occupied territories, and a list of non-eligible areas is published using postal codes. However, verifying the origin of agricultural products remains complex because of shared environmental and geographical features between Israeli and settlement areas. According to analysis by the Global Echo Litigation Center, about 20% of Israeli exports to the European Union come from these settlements. Some companies may try to obscure the origin of their goods by using postal codes from illegal settlements as the official origin or by providing false addresses within Israel. Other methods include mixing products from Israel with those from settlements during packaging or processing, making it harder to identify their true origin. The EU’s Deforestation Regulation, which aims to stop deforestation linked to imported goods, has faced delays due to high compliance costs. A simplified version of the rule is expected to cut these costs by about 75%. In the US, the Uyghur Forced Labor Prevention Act shifts the responsibility of proving that goods are not made using forced labor to the importers, rather than relying on inspections after the fact. This approach may offer a model for future regulations that require prior approval of companies rather than checking each shipment individually. However, enforcing sanctions on goods from the West Bank is complicated by the fact that all exports, whether from Palestinian areas or Israeli settlements, go through Israeli ports. These ports have been found to be unreliable in certifying the origin of goods. There are also concerns that these sanctions could have unintended effects, such as harming trade with Israel, which exports pharmaceuticals, cosmetics, and technology. Additionally, the new rules might discourage companies from importing from the West Bank, which could hurt Palestinian farmers who rely on agricultural exports for their livelihoods. A key issue is who will bear the cost of verifying the origin of goods—whether it will be customs authorities or the importers themselves.
