It is a method of suspending or pausing customs duties on certain goods or services between two or more countries.
This usually happens during:
Trade negotiations (for example, if they are preparing a new agreement).
Economic crises (to ease the burden on markets).
Or with the aim of encouraging trade between specific parties.
Example:
If two countries decide to halt the trade war, they might announce a "pause" on tariffs, meaning temporarily they will not impose additional taxes on each other's goods.
