EORI: the customs identity
Any business importing into or exporting out of the EU or UK needs an EORI number; customs systems reject declarations without one. It is issued once per legal entity by a member state (or HMRC in the UK) and used across all its customs activity in that territory. A non-EU company that wants to act as importer into the EU generally needs an EU EORI, which in turn usually requires EU establishment or a fiscal/indirect representative — a frequent surprise for exporters trying to sell DDP into Europe.
The US equivalent identity is not an EORI but a CBP-recognised importer number (often tied to an IRS/EIN or a customs-assigned number) plus, for many importers, a customs bond. Different jurisdiction, same underlying idea: customs must be able to identify and hold accountable the party bringing goods in.
Importer of record: where liability sits
The IOR is legally answerable to customs for classification, valuation, duty payment, and compliance — the buck stops there even when a broker files the entry and a forwarder moves the cargo. This is why Incoterms matter beyond cost: under DDP, the seller must act as (or arrange) IOR in the destination country, taking on that liability abroad; under DAP or FCA, the buyer is naturally the IOR in its home country.
When neither buyer nor seller can be IOR in a given country — common in e-commerce, spare-parts, and drop-ship flows — specialised importer-of-record services step in for a fee, holding the compliance obligation and the bond. For forwarders, an IOR request is both an opportunity (bundled brokerage and financing margin) and a liability to price carefully, because the IOR carries the penalty exposure if the entry is wrong.
