The second way of looking at free trade agreements as public goods is related to the growing trend that they are „deeper“. The depth of a free trade agreement relates to the additional types of structural policies it covers. While older trade agreements are considered more „flat“ because they cover fewer areas (for example. B tariffs and quotas), recent agreements cover a number of other areas, ranging from e-commerce services and data relocation. Since transactions between parties to a free trade agreement are relatively cheaper than those with non-parties, free trade agreements are considered excluded. Now that deep trade agreements will improve the harmonization of legislation and increase trade flows with non-parties, thereby reducing the exclusivity of free trade agreements, next-generation free trade agreements will take on essential characteristics for public goods.  Governments with free trade policies or agreements do not necessarily abandon import and export controls or eliminate all protectionist policies. In modern international trade, few free trade agreements lead to completely free trade.

 Although a dispute in free trade areas is not the subject of litigation within the WTO`s dispute resolution body, „there is no assurance that WTO panels will comply and reject jurisdiction in a particular case.“  At the international level, there are two important databases on access to free trade, developed by international organizations for policy makers and businesses: WTO members are required to communicate their free trade agreements to the secretariat, this database is based on the official source of information on free trade agreements (called regional trade agreements in the WTO language). The database allows users to obtain information on trade agreements that are communicated to the WTO by country or theme (goods, services or goods and services). This database provides users with an up-to-date list of all existing agreements, but those that are not notified to the WTO may be lacking. In addition, reports, tables and graphs containing statistics on these agreements, including preferential tariff analysis, are presented.  There are significant differences between unions and free trade zones.
