The term 'mandatory' in Israel's mandatory certification needs to be understood from multiple perspectives. According to the laws and regulations promulgated by the Israeli state, all goods must be inspected by the SII organization upon entry into Israel to confirm that the goods comply with Israel's national standards. The Israeli "Industrial Trade and Labor Agency" refers to this certification process as "compression of conformity", where goods are inspected in batches, meaning that each imported goods must be inspected. The test certificate issued during the last inspection can be used for the next inspection of goods, but it cannot directly replace this inspection and will only shorten the time the goods stay at customs, In order to save some customs stagnation costs for customers (usually around 40 days for SII cargo inspection).
