The few items merchants are allowed to trade in are divided into three categories: food, medicine and detergent. Everything else is forbidden - including building materials (which are necessary to rehabilitate Gaza's ruins and rebuild its infrastructure), electric appliances such as refrigerators and washing machines, spare machine and car parts, fabrics, threads, needles, light bulbs, candles, matches, books, musical instruments, crayons, clothing, shoes, mattresses, sheets, blankets, cutlery, crockery, cups, glasses and animals. Many of the banned products are imported through the tunnels and can be found in Gaza's markets.
Pasta, which had been forbidden in the past, is now allowed, after U.S. Senator John Kerry expressed his astonishment at the ban during a visit to Gaza in February. But tea, coffee, sausages, semolina, milk products in large packages and most baking products are forbidden. So are industrial commodities for manufacturing food products, chocolate, sesame seeds and nuts. Israel does allow importing fruit, milk products in small packages and frozen food products as well as limited amounts of industrial fuel.
