Final answer:
Restrictive administrative and technical regulations can create barriers to trade, but safety and health regulations are not one of them.
Step-by-step explanation:
Restrictive administrative and technical regulations can create barriers to trade, with examples including antidumping regulations, product size regulations, common agricultural policies, and safety and pollution regulations. However, one form of barrier to trade that is not created by restrictive regulations is safety and health regulations. Safety and health regulations are put in place to protect consumers and workers, and they are not intended to restrict trade.
