A long time ago, people from different countries in Europe used to trade different things with each other. But sometimes, when they tried to send things from one country to another, the people in charge would stop the things and not let them through. This made it hard for people to trade and send things to different countries.
So, the leaders of the countries got together and came up with an idea. They decided to make a special portal called the European Customs Information Portal, or ECIP for short. This portal would help people who wanted to send things to different countries by telling them what they needed to do to get their things through the customs people.
Now, when someone wants to send something from one country to another in Europe, they can go to the ECIP portal and type in what they want to send and where they want to send it. The portal will then show them all the rules they need to follow and paperwork they need to fill out.
This helps people make sure they do everything right and their things can get through the customs people without any problems. So, the ECIP portal is like a helpful guide that makes it easier for people to trade and send things to different countries in Europe.
