Imposing some sort of cost on trade that raises the price of traded products is more likely an example of a trade barrier. Trade barriers are government-imposed restrictions or policies that make it difficult or expensive for imports and exports to flow freely between countries. They can take various forms, including tariffs, quotas, and trade restrictions, aimed at protecting domestic industries, reducing imports, or promoting exports.

A trade surplus refers to a situation where a country's exports are higher than its imports, resulting in a positive balance of trade. A trade deficit, on the other hand, occurs when a country's imports exceed its exports, leading to a negative balance of trade.

A trade incentive, as the name suggests, is a deliberate measure taken by governments or organizations to encourage trade. It can include various policies and initiatives such as preferential tariffs, tax breaks, subsidies, or investment incentives to stimulate trade activities and attract foreign investments.

Therefore, based on the given context, imposing a cost on trade that raises the price of traded products is more likely an example of a trade barrier rather than a trade surplus, trade deficit, or trade incentive.
