Such regulation typically includes powers for regulators to set product safety requirements, which must be met before the goods can be marketed. For example, the European Union (EU) adds a general safety provision to products, which mandates that goods are safe. If they are deemed unsafe, public law sanctions follow, along with any liability that may be incurred by suppliers subject to private law claims for harm from product defects. Post-marketing controls have also developed, including over intermediaries such as wholesalers or retailers (although often subjected to less strict requirements than for manufacturers and importers). These controls include powers to ban goods found to be unsafe by the authorities, to recall goods, to warn the public about likely safety risks, and even to require product accident or incident reports from suppliers.
