Bulgaria EORI Number & Customs Registration for Importers & E-Commerce

If your Bulgarian EOOD imports goods from China, the United States or any other third country — or exports outside the EU — an EORI number is not optional. It is the single identifier the Bulgarian Customs Agency (Агенция Митници) and every other EU customs authority uses to identify you on every declaration, transit document and import VAT entry. The good news: a Bulgarian EORI is free, the application is straightforward through the Customs Agency e-portal at ep.customs.bg, and it is issued within one to three business days. The complication: 2026 is the year EU e-commerce customs rules shift — the EUR 150 duty-free threshold ends, an interim EUR 3 per-item duty starts on 1 July 2026, and a Union-wide customs handling fee launches in November 2026. This guide walks the EORI process and the customs setup decisions a foreign-owned Bulgarian e-commerce or import business has to make right now.

What an EORI Actually Is — And Why Your EOOD Needs One

EORI stands for Economic Operators Registration and Identification. The legal basis is Article 9 of the Union Customs Code (Regulation (EU) 952/2013) read together with Article 1(18) of the Commission Delegated Regulation (EU) 2015/2446 and Article 7 of Implementing Regulation (EU) 2015/2447. In plain terms: every economic operator established in the EU customs territory must register once with the customs authorities of its Member State to obtain a number that uniquely identifies it for all customs purposes EU-wide.

For a Bulgarian EOOD the EORI is issued by the Bulgarian Customs Agency (Агенция Митници) under the Ministry of Finance and takes the format BG + your 9-digit UIC (the Bulgarian unified company code from the Commercial Register). A Wise or Stripe account does not give you an EORI. A VAT number does not give you an EORI. The Bulgarian Trade Register entry alone does not give you an EORI. The Customs Agency registration is a separate, standalone step.

Who needs an EORI

An EORI is required for every Bulgarian-established economic operator that performs at least one of the following:

• Imports goods into the EU customs territory from a third country (China, US, UK, Switzerland, Turkey).
• Exports goods from the EU customs territory to a third country.
• Files a transit declaration (T1, T2) under the Common Transit Convention.
• Submits an Entry Summary Declaration (ENS) or Exit Summary Declaration (EXS) for safety and security.
• Applies for a customs decision — binding tariff information (BTI), binding origin information (BOI), an AEO authorisation, a special procedure.

Where you actually clear goods in Bulgaria

The Bulgarian Customs Agency operates regional and territorial directorates across the country. For a foreign-owned EOOD the practical entry points cluster around six locations:

• Sofia Airport (Аерогара София) — primary air-freight entry point; default for express courier shipments from Asia and the US.
• Burgas Port — main Black Sea container terminal; principal sea-freight entry from China, Turkey and the Black Sea region.
• Varna Port — secondary Black Sea container and ro-ro terminal.
• Plovdiv — inland clearance for road freight from Turkey, the Middle East and Central Asia via the Kapitan Andreevo crossing.
• Russe Port and Russe Danube terminal — Danube river-freight gateway; relevant for transhipment from EU western ports via the Rhine-Main-Danube corridor.
• Kapitan Andreevo (border crossing with Turkey) — the EU's largest land border crossing by truck volume; the dominant road-freight customs office for goods originating in Turkey, the Middle East and Asia.

Choice of customs office is usually a logistics decision driven by the carrier's network rather than a tax one. The EORI is the same regardless of entry point.

Who does not need an EORI

The EORI obligation does not apply to:

• Private individuals who lodge written or electronic customs declarations occasionally — fewer than ten times per year — provided no economic activity is involved.
• EOODs trading only within the EU (intra-Community supply or acquisition). Intra-Community movements are VAT events, not customs events; the EORI is irrelevant.
• Marketplace sellers using full marketplace-of-record fulfilment (for example Amazon FBA EU dispatched from Polish or Czech warehouses) where the marketplace handles import on its own account. The moment the EOOD becomes importer of record, the EORI becomes mandatory.

The Legal Basis — EU and Bulgarian Layers

Bulgarian customs law sits on top of two EU layers and a Bulgarian implementing statute. Understanding the layering matters when you are reading guidance from accountants or platform vendors — claims that "Bulgaria requires X" sometimes describe an EU-level rule that has nothing to do with Bulgarian discretion.

Two practical consequences flow from this stack. First, the EORI obligation is EU-level and uniform — there is no Bulgarian discretion to demand more documents than the UCC permits. Second, sanctions for customs offences are national; the Bulgarian Customs Act sets the penalty ranges and the Customs Agency administers them, but the substantive obligation is uniform across all 27 Member States.

How to Apply for a Bulgarian EORI — Step by Step

Two routes exist: electronic via the Customs Agency e-portal (ep.customs.bg) using a qualified electronic signature (QES), or paper at any of the regional customs bureaus (Sofia, Plovdiv, Burgas, Varna, Russe and other regional offices). Electronic is faster, cheaper and the only sensible route in 2026.

1. Confirm prerequisites. The EOOD must be entered in the Bulgarian Commercial Register, have a Bulgarian UIC, and the manager (or an attorney with notarised PoA) must hold a Bulgarian qualified electronic signature certificate from a Qualified Trust Service Provider — B-Trust, InfoNotary, StampIT or Borica.
2. Register on ep.customs.bg. Create an e-portal user account using the QES. The portal authenticates against the Bulgarian QTSP infrastructure; foreign electronic signatures (eIDAS-recognised) are technically accepted but in practice the portal handles Bulgarian QES most reliably.
3. Open the EORI application form. Inside the e-portal, navigate to the EORI registration service. The form pulls the EOOD's data from the Commercial Register automatically — name, UIC, registered address, manager — leaving the customs-specific fields (anticipated activity profile, contact details, authorised representative if any) for completion.
4. Attach supporting documents. Trade Register extract (Удостоверение за актуално състояние) — not mandatory but speeds processing; ID or passport copy of the legal representative; notarised power of attorney if the application is filed by a third party with the specific power to register an EORI explicitly stated.
5. Sign and submit. The application is signed with the QES and submitted electronically. A confirmation receipt is issued automatically with the application reference number.
6. Receive your EORI. Within 1-3 business days the Bulgarian Customs Agency issues the EORI number — typically BG + UIC. The EORI is registered in the EU central EORI database and is immediately searchable through the European Commission's EORI validation tool. Issue notification arrives by email and is available in the e-portal inbox.

The 2026 E-Commerce Reform — EUR 150, EUR 3 and the Handling Fee

For a Bulgarian-domiciled e-commerce operator importing from third countries to EU consumers, 2026 is the year the rules tighten. Two reforms matter and both bite in the second half of the year.

The EUR 150 duty exemption is being removed

Since 2021, low-value imports below EUR 150 sent directly to EU consumers have been exempt from customs duty (though not from import VAT). The exemption was paired with the introduction of IOSS — the Import One-Stop Shop — which let sellers collect destination-country VAT at the point of sale and remit through a single EU registration. The policy worked imperfectly: it lowered friction for legitimate low-value e-commerce, but it also created a structural undervaluation incentive. On 12 December 2025 the EU Council agreed to remove the EUR 150 exemption as part of the broader EU customs reform.

The interim EUR 3 per-item duty from 1 July 2026

Pending the full customs reform, an interim flat customs duty of EUR 3 per item applies to low-value parcels (below EUR 150 intrinsic value) sent directly to EU consumers from third countries from 1 July 2026 — provided VAT is settled via IOSS. Based on the Council agreement of 12 December 2025, the duty is expected to apply per item according to tariff heading, not per parcel — meaning a five-item parcel triggers EUR 15 of interim duty. Final per-item versus per-parcel mechanics will be confirmed by the Commission implementing act. For Bulgarian e-commerce operators sourcing from China this is the single largest cost change of the year.

The EU customs handling fee from November 2026

A Union-wide customs handling fee on low-value imports launches in November 2026 — EUR 2 per consignment, as confirmed by the Council in its December 2025 agreement. Some Member States (Belgium, France, Italy, the Netherlands, Romania) have already introduced or are introducing national customs handling fees that pre-date the Union-wide one. Bulgaria has not, as of June 2026.

IOSS Strategy — When It Helps a Bulgarian Seller and When It Doesn't

IOSS (Import One-Stop Shop) is the EU's mechanism for B2C VAT collection on imported goods up to EUR 150 — introduced by Council Directive (EU) 2017/2455 with its operational rules added by Council Directive (EU) 2019/1995 and operative since 1 July 2021. A non-EU or EU seller registers for IOSS in one Member State (in Bulgaria, through the NRA portal), collects destination-country VAT at the point of sale at the customer's national rate (20% for a Bulgarian consumer, 19% Cyprus, 21% Netherlands, etc.), and remits the total monthly through a single return. Customs clearance at the EU border is fast-tracked because import VAT is treated as already paid.

Where IOSS makes sense for a Bulgarian EOOD

• You ship B2C from outside the EU directly to EU customers in multiple Member States, and parcel values are ≤ EUR 150.
• You want frictionless delivery — IOSS shipments clear customs faster because import VAT is already accounted for.
• You have low return rates — IOSS reversal mechanics for returns are administrative.

Where IOSS does not help

• Goods above EUR 150 — IOSS is closed to higher-value items, which go through standard import VAT.
• B2B sales — IOSS is B2C only.
• EU-warehoused stock — once goods are in EU free circulation, IOSS is irrelevant; the OSS regime applies for distance sales.
• Established EU seller selling EU-origin goods — no import event, no IOSS.

From 1 July 2026 IOSS continues to operate but no longer absorbs the new EUR 3 per-item duty. The seller charges VAT at the point of sale (IOSS) and pays EUR 3 per item at customs clearance — through the postal operator, the courier or a customs broker. The IOSS registration itself does not change; the cost calculus does. See our Bulgaria dropshipping VAT setup guide for how the new layer affects margin on a sample basket.

AEO — The Authorised Economic Operator Ladder

AEO is the EU's trusted-trader programme under Articles 38-41 of the Union Customs Code. An economic operator that meets the criteria — compliance with customs and tax law, satisfactory commercial-record management, financial solvency, practical or professional competence, and (for the security variant) appropriate security standards — can be granted AEO status. The status is valid EU-wide and is the entry ticket to several customs simplifications.

Three AEO variants

Is AEO worth it for a foreign-owned Bulgarian EOOD?

Honest answer: usually not, until volume builds. The AEO application file is substantial — a self-assessment questionnaire of more than 90 questions, supporting evidence on each criterion, an on-site customs audit. Total preparation typically runs three to nine months and EUR 5,000-15,000 of professional time. The simplification benefits accrue in proportion to declaration volume: for a small EOOD with 1-10 declarations per month, the operating value is limited; for an EOOD scaling beyond 50-100 declarations per month, AEOC pays back within 18-24 months in reduced clearance time, reduced guarantees and lower inspection rates. Bulgaria recognises mutual-recognition AEO status from non-EU jurisdictions (US C-TPAT, Japan AEO, China AEO, Korea AEO, Norway AEO, Switzerland AEO).

Direct vs Indirect Representation — The Liability Decision

Most importers do not file customs declarations themselves — they engage a customs broker, freight forwarder or law firm to act as customs representative. Article 18 of the Union Customs Code defines two forms of representation and the liability consequence of choosing one over the other is significant.

For a Bulgarian-established EOOD the structural choice is clear: direct representation. The EOOD is the customs debtor (which it would be in any event), and the broker fee is lower. Indirect representation only becomes relevant in two scenarios — when the EOOD's owner has not yet incorporated and the goods are arriving in the name of a non-EU person, or when the broker is offering an indirect-representation package for a strategic reason (typically a financing arrangement). In either case, understand that the broker has a direct interest in penalty exposure and behaves accordingly — closer scrutiny of declarations, higher fees, faster termination of the relationship at the first sign of friction.

Already importing under indirect representation? Free broker-contract audit as part of the retainer scoping call — most operators are paying 30-50% above market for liability that the EOOD does not need to transfer.

Common Customs Mistakes We See on Audit

From the customs files we audit on new tax-and-accounting retainers, five mistakes repeat with high frequency. None of them are fatal — all are correctable — but each can cost an unprepared importer time and money in the first audit cycle.

1. Operating without an EORI on the first shipment

The most common version of the problem. The seller orders sample stock from a Chinese supplier before incorporating the EOOD; goods arrive at Sofia airport or Burgas port; the customs broker requests an EORI; the founder discovers the EORI is a 1-3 day setup. Outcome: temporary-storage fees at EUR 5-30 per pallet per day until the EORI is issued. Apply for the EORI the same week you incorporate the EOOD, before any goods are shipped.

2. Wrong tariff classification (CN code)

The Combined Nomenclature (CN) is the EU's 8-digit goods classification system; the TARIC adds two more digits for EU measures. Every import declaration carries a CN/TARIC code that determines the duty rate. A mis-classified import can over- or under-pay duty by single-digit percentage points — for some product categories double-digit. Examples from the 2026 Combined Nomenclature: 6109.10.00 (cotton T-shirts) carries a 12% MFN duty; 8517.13.00 (smartphones) carries 0% MFN; 9503.00.99 (other toys) carries 0% to 4.7% depending on the precise subheading. A single wrong digit can move duty by hundreds of euro per pallet. Bulgarian Customs accepts Binding Tariff Information (BTI) applications under Article 33 UCC — a free written ruling on the correct classification of a specific product, valid for three years. For sellers with stable SKU lists, a BTI per major product line is the right hedge.

3. Mis-stated customs value

The customs value under Article 70 UCC is the transaction value (price paid or payable for the goods on sale for export to the EU), adjusted under Article 71 for items like royalties, transport to the EU border and licence fees. Common errors: omitting freight to the EU border, omitting royalty payments to the supplier's IP holder, omitting buying commission paid to a sourcing agent. The customs authorities cross-check declared values against industry references; large undervaluation triggers post-clearance audit under Article 48 UCC and recovery of the duty differential with interest.

4. Missing or stale proof of origin

Preferential origin under EU trade agreements (with Canada, Japan, Korea, UK, Vietnam, Singapore and others) requires documentary proof — REX statement, EUR.1, or the trade-agreement-specific equivalent — supplied at the time of the import declaration. Importers often forget to request the document from the supplier, or accept a stale form that no longer matches the current trade agreement text. Without valid proof, the preferential rate is denied and standard MFN duty applies.

5. Missed deferred-VAT regime — when product mix actually qualifies

Bulgaria allows deferred payment of import VAT under Article 167a ЗДДС, but the regime is product-restricted — it applies only to a closed list of commodities (salts, construction materials, chemicals, ores, metals and similar industrial inputs) with customs value of at least EUR 25,565 per consignment (the legacy BGN 50,000 statutory threshold at the 1.95583 conversion rate). For an e-commerce or consumer-goods EOOD the regime does not apply; for an industrial or construction-supplies importer it can be a material cash-flow lever. We assess eligibility at retainer onboarding rather than recommending it as a default — most foreign-owned EOODs we work with operate outside the eligible product list and pay import VAT at the border or via the courier broker as standard.

What This Costs — and What It Should Not Cost

The market for EORI and customs setup services in Bulgaria has wide quotes. Three reference points for a foreign-owned EOOD.

EORI registration

Free at the Bulgarian Customs Agency. A reasonable professional fee for a standalone EORI filing is EUR 100-300 — covering the QES use, document preparation and PoA where needed. Anything above EUR 500 for a standalone EORI is overpriced.

Routine customs declarations (brokerage)

Per-shipment commercial brokerage in Bulgaria runs EUR 30-80 per declaration for standard goods at major customs offices (Sofia, Plovdiv, Burgas, Varna) — higher for specialised goods or special procedures.

AEO authorisation

Total professional preparation: EUR 5,000-15,000 for AEOC, depending on operational complexity. AEOS adds EUR 3,000-8,000 for the security audit overlay. We only recommend AEO pursuit at volumes above 50-100 monthly declarations.

Innovires retainer scope

Within our tax-and-accounting retainer for foreign-owned EOODs that import goods, EORI registration is included at no extra fee; routine customs declarations are handled through our preferred broker network at standard commercial rates; AEO is a separate engagement when volume justifies it. Why a regulated Bulgarian law firm rather than a customs broker alone — the privilege coverage and the integrated VAT/customs view are the two practical reasons.

Common Myths to Ignore

"My VAT number is my EORI."

False. The VAT number is issued by the NRA for VAT purposes. The EORI is issued by the Customs Agency for customs purposes. They are distinct registrations on distinct systems. They often share the underlying 9-digit UIC, but they are not interchangeable on customs declarations.

"I need a different EORI for each EU country I import through."

False. The EORI is single and EU-wide. A Bulgarian EORI lets you import through Rotterdam, Hamburg or Constanța equally. Multiple EORIs per economic operator are not permitted under Article 9 UCC.

"IOSS removes the need for an EORI."

False. IOSS is a VAT scheme; it does not affect customs identification. Even with IOSS in operation, the seller (or its customs representative) needs an EORI for the customs side of the import. Small B2C parcels shipped under IOSS often use the postal operator's EORI for clearance, but the seller's own customs file at scale needs the seller's own EORI.

"Once I have AEO I never get inspected."

False. AEO holders are inspected less and more predictably, not never. The status is a risk-rating advantage, not an immunity.

"A customs broker who is also indirect representative is cheaper."

Almost always false. The indirect representative takes joint-and-several liability for the customs debt — and prices the fee accordingly. The lower headline rate is a marker that something else is wrong (often that the broker is also the upstream seller and is bundling margin into the customs fee).
