IOR 101: what the Importer of Record is actually liable for in the EU
Importer of Record is not just a name on a shipping document. It is the party customs holds responsible for duty, VAT, classification accuracy, and regulatory compliance.

Non-EU sellers often treat "Importer of Record" as an administrative label — somebody who fills in a form so the cargo can move. It is not. The IOR is the legally responsible party for the import, and understanding what that responsibility covers is the difference between a clean supply chain and a tax authority on the phone.
Customs debt — the first liability
The IOR owes the customs debt on the imported goods. That is duty plus import VAT, calculated on the declared customs value plus freight and insurance to the EU border. If customs later decides the declaration was wrong — classification dispute, valuation challenge, missed anti-dumping duty — the IOR pays the difference.
Customs can revisit a declaration for up to three years after the import (longer if fraud is alleged). A classification error on a repeated import flow can turn into a multi-year retroactive bill quickly.
Classification accuracy — where most disputes happen
HS codes, or more precisely the EU's Combined Nomenclature (CN) eight-digit codes, drive the duty rate. Pick the wrong code and you either pay too much (your problem, not recoverable) or too little (customs' problem, they come after you).
The classification is the IOR's responsibility. Practically, a competent IOR has a customs broker in-house or on retainer who knows the nomenclature for the sectors they handle. A company just willing to put their EORI on a declaration without classifying properly is not really acting as IOR in any meaningful sense.
Valuation
Customs value is, roughly, the transaction value: what you actually paid for the goods, plus certain adjustments. If the sale is between related parties (your factory in Shenzhen selling to your US holding company selling to the EU market), customs may challenge the valuation as non-arm's-length.
Defending a valuation challenge needs documentation: the transfer pricing method, the pricing studies, benchmarks. The IOR is the one facing customs on this, so the IOR wants the documentation upfront.
Regulatory compliance
Beyond duty and VAT, imported goods have to meet EU product regulations. CE marking for many electrical and mechanical products. REACH compliance for chemicals. RoHS for electronics. Food contact materials rules. Textile labelling rules. Dual-use controls for controlled items.
The IOR is the party customs and market-surveillance authorities hold responsible for compliance on the goods it imports. If a product is later found to be non-compliant, the IOR can be ordered to recall or destroy it.
This is why a real IOR asks questions about the product before accepting the job. "Is this electronic device CE marked?" "Do the children's toys have the EN 71 certificate?" A broker who does not ask these questions is one who will have problems.
EORI numbers
Every IOR needs an EORI — the Economic Operators Registration and Identification number. It is how the EU customs systems identify you. Applying for one is free, takes a few days in most member states, but the applicant must be EU-established.
Non-EU companies cannot get their own EORI. That is what makes the IOR-as-a-service model necessary — somebody else lends their EU establishment and their EORI to make the import possible.
Why the IOR matters more than who pays the freight
On a typical commercial invoice, people focus on Incoterms (who pays for shipping) and freight cost. Those are commercial questions. The IOR question is a compliance question, and compliance is usually more expensive than freight when it goes wrong.
Pick an IOR provider who actually classifies, actually asks about CE and REACH, actually files under their own EORI, and actually holds the documentation for four-plus years. That is what the word means in practice.
