Binding Origin Information
BOI decisions are binding on the holder and on the EU customs authorities. They are normally valid for three years from the date of issue.
How and where to apply for a BOI decision?
Applications should be made in writing to the competent authorities in the EU country in which a company is established or where it intends to use the BOI. You must make sure that the description of the goods in the Binding Origin Information is identical to the goods that you are exporting or importing.
The authorities have 120 days from the date they registered your application to take a decision.
Note that the existence of Binding Origin Information does not exempt you from the requirement to provide proof of origin.
