What’s the difference between provenance and origin

The words ‘provenance’ and ‘origin’ of goods are often used interchangeably. Nevertheless, they have different meanings. Particularly in the world of customs matters. ‘Provenance’ relates to the customs status of the goods. Are they Union goods (goods that are produced in the EU, or that have already been imported from a non-EU country) or non-Union goods (goods from non-EU countries)? ‘Origin’ refers to where a product is manufactured, produced or grown.
