Importer of Record UK (IOR): who they are, when required and what liability they bear towards HMRC

What is an Importer of Record (IOR) — operational definition

The Importer of Record is the entity whose GB EORI number appears in the "Importer" field of the customs declaration submitted through the Customs Declaration Service (CDS). In practice this means the legal or natural person who takes on the legal and financial burden of the import — even if they never physically handle the goods nor complete the paperwork themselves.

In everyday speech "importer" is often conflated with "buyer". In the UK customs system these two roles can diverge. The buyer may be in Germany, the goods may be stored in the UK by a third party, and the IOR may be somebody else again. That is why, before you issue a proforma invoice for clearance, you must unambiguously establish: who is entered as the importer on the declaration, and who is merely the consignee (physical recipient). These are separate fields on the CDS declaration and carry different liability scopes.

The IOR, in line with the official GOV.UK guidance on declaring goods at customs:

• Submits (or instructs a customs agent to submit) the import declaration in CDS,
• Is answerable to HMRC for the accuracy of the declaration — tariff classification, customs value, origin of goods, required licences and authorisations,
• Accounts for import duty and import VAT (directly or via Postponed VAT Accounting (PVA)),
• Retains the full set of customs documents for a minimum of 4 years in line with the HMRC record-keeping requirements,
• Is the entity to whom HMRC addresses any C18 Post Clearance Demand Note if irregularities are identified.

"Established in UK" — the critical post-Brexit requirement few talk about

The biggest gap in overseas knowledge about importing into the UK concerns not the EORI but the established importer status. From 1 January 2022, HMRC has progressively restricted the ability to submit standard declarations for entities without a physical presence in the United Kingdom. The rules are set out in GOV.UK — Check if you're established in the UK for customs.

In short: "established in UK" means your company has a permanent business establishment in the United Kingdom — a registered office, genuine administrative infrastructure and a person responsible for customs matters. A registered address rented in London through a "virtual office" service alone is not enough if there is no real operational activity behind it.

The consequences are serious: if you are non-established, then:

• Your customs declaration must be submitted by a UK customs agent in indirect representation mode (this point is pivotal — we will return to it),
• You cannot take advantage of certain customs simplifications intended for non-established traders (e.g. the simplified declaration procedure generally requires UK presence),
• A customs agent who agrees to indirect representation becomes jointly and severally liable for the customs debt — which dramatically changes the commercial arithmetic of such an engagement (and is why most agents refuse to act for non-established traders).

The EasyClearance team sees this daily in practice: an overseas company opens sales into the UK, registers only a GB EORI (without a UK company), and then wonders why no agent will sign off the clearance. That is precisely the collision with the "established in UK" requirement. The way out? Either register a real UK company, or work with someone who knowingly accepts joint liability under indirect representation.

IOR vs Exporter of Record vs Customs Agent — do not confuse these three roles

Three concepts that are most frequently confused in cross-border e-commerce. Each describes a different role in the clearance chain and a different allocation of liability:

Key takeaway: EasyClearance is a Customs Agent, not an IOR. Even when we take indirect representation and share liability with the client, the client remains the trading party — the seller of the goods — while we remain the service provider. This distinction has tax consequences (who reclaims import VAT), operational ones (who engages with HMRC on audit) and reputational ones (whose name appears on the UK purchase invoice).

Three IOR scenarios — how it looks in practice

Instead of abstract theory — the three most common patterns the EasyClearance team encounters each week.

Scenario 1: Classic B2B import (a UK client buys from an overseas supplier)

A Polish furniture factory sells a pallet of armchairs to a distributor in Manchester. Incoterms: FCA Poznań or CPT Dover. Who is the IOR?

• IOR = the UK distributor. They hold their own GB EORI, are established in UK and have the infrastructure to account for import VAT (usually via PVA).
• The Polish supplier acts as the Exporter of Record on the Polish side — filing the export declaration in PUESC.
• The EasyClearance team can act as customs agent for the UK distributor under direct representation — submitting the declaration on their behalf, while they remain answerable for its content.

This is the cleanest and safest pattern. The Polish supplier carries no customs liability in the UK. The full "being the importer" burden sits with the buyer.

Scenario 2: Amazon FBA UK — the wall that catches out most overseas sellers

A Polish seller ships their own goods to an Amazon warehouse in Coventry (FC BHX4). Amazon is only a fulfilment partner — it does not own the goods and is not the IOR. So who is the Importer of Record?

• IOR = the Polish seller. They must hold a GB EORI and — if using a standard declaration — be established in UK. The most common route: registering a UK Limited Company or a branch, and then obtaining a GB EORI for that entity.
• Amazon requires that on the commercial invoice, packing list and CMR the Importer field show the seller's details, not Amazon's. Amazon never signs off as IOR — this is clearly set out in Seller Central policy.
• Import VAT can be accounted for via PVA — provided you have previously registered for the PVA scheme and hold a UK VAT registration.

In this scenario the overseas company MUST take on the IOR role. There is no "shortcut" path via a UK customs agency that "takes it off your hands" — such an offer either hides an irregularity or amounts to indirect representation with joint liability (which is legal, but is not cheap and is not "writing off" the IOR).

Scenario 3: DDP e-commerce (selling to UK consumers with duty paid)

A Polish e-shop sells cosmetics to consumers in the UK. Terms: DDP (Delivered Duty Paid) — the end customer sees no charges on delivery. Who is the IOR?

• A UK consumer cannot be the IOR — a private individual acting as a non-trader has no EORI and no mechanism to account for import VAT.
• The Polish company elects to assume the IOR role → it must hold a GB EORI and be established, or use the IOSS alongside UK VAT registration scheme for goods ≤£135, where the seller charges UK VAT at checkout and there is no classic import (described in GOV.UK — VAT on goods sold directly to UK customers).
• For values above £135 per parcel — classic customs clearance with the Polish company as the IOR. Here the established requirement, or indirect representation, applies again.

DDP without UK presence is one of the most frequent sources of customs problems — parcels stuck at DHL East Midlands, demands for additional VAT, refusals of refund, unhappy customers. In such cases the EasyClearance team first proposes a sales-structure audit, and only then a specific clearance model.

IOR liability towards HMRC — what can realistically land on your desk

For as long as everything is going well, being the IOR is invisible. The problems start when HMRC runs a compliance audit or risk analysis on a declaration. At that point the full list of IOR obligations comes to life. The official rules on audit are set out in HMRC Notice 199A: Compliance checks.

The most common HMRC instruments directed at the IOR

• C18 Post Clearance Demand Note — a formal demand for additional duty/VAT, most often following a correction to HS classification or customs value. Payment term: 30 days. A C18 can be appealed, but the burden of proof rests with the IOR.
• Inland Pre-Clearance (IPC) check — HMRC can halt the clearance before release into free circulation and request documentation. Business pressure deadlines (customers, warehouse) run at the IOR's cost.
• Customs Civil Penalty — a financial penalty for an irregularity in the declaration, even where there has been no loss of revenue. Basis: HMRC — Customs Civil Penalties.
• Withdrawal of customs authorisations (CFSP, IPR, OSR, Customs Warehouse) in more serious cases of non-compliance.

Three areas where the IOR most often gets caught out

1. HS classification. An overseas company shipping to the UK classifies an "electronic gate remote" under one heading; HMRC considers another with a higher duty rate. Difference × number of declarations over 3 years = several thousand pounds of correction. That is why it is worth using the HS code verification procedure before the first clearance.
2. Customs value. Understating the value by omitting commissions, licensing fees or pre-packaging transport is a classic error. HMRC reconstructs value from invoices and market statistics.
3. Origin and preferences. Wrongly declaring EU origin and using TCA preferences, when in reality the goods contain Chinese components — duty top-up plus penalty.

The EasyClearance role — customs agent, not IOR (and why that is good news)

Back to the most important operational distinction. The EasyClearance team acts as a customs agent, not as an Importer of Record. That means:

• Your company remains the trading party — the goods are yours, the sales invoice is yours, the customer relationship is yours.
• On the CDS declaration your GB EORI appears in the Importer field, and our GB EORI appears in the Declarant/Representative field.
• We work in two modes: direct representation (client is established — full liability on their side) and indirect representation (client is non-established — we take on joint and several liability alongside the client).
• Indirect representation is a service we consciously take on for selected clients following a sales-structure audit. We then share liability jointly and severally — this is not "writing off" the IOR, it is a shared assumption of liability.

Why is this good news? Because the alternative — agencies offering themselves as full IOR on their own EORI for any client — often operates in a grey zone. HMRC is increasingly aggressive in pursuing structures in which someone declares themselves as the importer without a real economic interest in the goods. The EasyClearance team prefers the simpler, transparent model: you are the IOR, we are your agent with genuine liability in indirect mode.

How to prepare for the IOR role — a checklist for the overseas company

If the analysis shows that in your structure you must be the IOR (e.g. FBA or DDP), here is the sequence of steps:

1. UK company registration — either a Limited Company, or a branch of the overseas company (the UK branch). The choice affects tax, but both options give you established status.
2. GB EORI number — registration is free and takes 3–5 working days. Without it there is no customs declaration.
3. UK VAT registration — mandatory on exceeding £90,000 or from the first B2C sale for supplies from abroad.
4. PVA (Postponed VAT Accounting) authorisation — allows import VAT to be accounted for on the VAT return rather than paid in cash at clearance. Details in our article on PVA UK.
5. Verification of customs value and HS codes for all major SKUs — before the first HMRC audit arrives. For HS codes, use the HS code verification procedure.
6. A customs document archive procedure — minimum 4 years, available on request from HMRC, with one named responsible person.
7. Selecting a customs agent — with a clear representation mode (direct/indirect) and an SLA on clearance time.

Frequently Asked Questions (FAQ)

What is an Importer of Record (IOR) in the UK?

An Importer of Record is the entity whose GB EORI appears in the Importer field of the customs declaration in CDS. They are answerable to HMRC for the accuracy of classification, customs value and origin of the goods, and for the payment of duty and import VAT. After Brexit, the IOR must in most cases also be "established in UK" — have a genuine business presence in the United Kingdom.

Can EasyClearance be my IOR?

No — the EasyClearance team acts as a customs agent, not as an Importer of Record. Under indirect representation we share joint and several liability with the client, but the IOR remains the client. Agencies that offer themselves as full IOR on their own EORI for any importer often operate at the edge of compliance, which is why we prefer the transparent customs-agent model.

Who is the IOR on Amazon FBA UK?

On Amazon FBA UK, Amazon is only a fulfilment partner and never acts as the IOR. The Importer of Record is always the seller — which means the overseas seller must hold a GB EORI, a UK VAT registration and established status (most commonly through registering a UK Limited Company). The "Amazon will handle customs for me" model does not exist.

Do I need a UK company to be the IOR?

In most scenarios — yes. The "established in UK" requirement (set out in GOV.UK — Check if you're established in the UK for customs) effectively forces either registration of a UK Limited Company or a branch of the overseas company. A rented registered address without real activity is not enough. Exception: working with a customs agent under indirect representation who knowingly takes on joint liability.

How does the IOR differ from an Exporter of Record?

The IOR (Importer of Record) acts on the side of the country of import (UK) and is answerable to HMRC. The EOR (Exporter of Record) acts on the side of the country of export (e.g. Poland) and is answerable to the Polish customs administration / PUESC. In a typical cross-border transaction the overseas supplier is the EOR, and the UK buyer is the IOR — two different roles, not synonyms.

How does direct differ from indirect representation by a customs agent?

Under direct representation the agent acts in the name of and on behalf of the IOR — and is answerable only for its own errors, while the IOR carries full customs liability. Under indirect representation the agent acts in its own name but on behalf of the IOR — and becomes jointly and severally liable with the IOR for the customs debt. Indirect is typically reserved for non-established clients and is more expensive.

What risk does the IOR bear on HMRC audit?

HMRC can issue a C18 Post Clearance Demand Note (top-up of duty/VAT), a customs civil penalty (a financial penalty for an irregularity in the declaration), and can withdraw customs authorisations such as CFSP or Customs Warehouse. Payment term for a C18 is typically 30 days, and the burden of proof on appeal rests with the IOR. Basis — HMRC Notice 199A: Compliance checks.

Can the IOR use Postponed VAT Accounting?

Yes — and practically every IOR with regular declarations should be using PVA. PVA allows import VAT to be accounted for on the VAT return rather than paid in cash at clearance, which eases cash flow. It requires prior registration on the PVA scheme and an active UK VAT registration. Details in our article on Postponed VAT Accounting (PVA) UK.
