B2B Shipping Guide

B2B Customs & Compliance for Portuguese Exporters

EORI numbers, commercial invoices, EUR.1 certificates, Incoterms and export VAT — what every regular business exporter from Portugal needs to know.

Shipping outside the EU requires customs compliance on every shipment. For businesses exporting regularly from Portugal, having the right documentation, registrations and processes in place is not optional — customs errors cause delays, fines and confiscated goods. This guide covers the core compliance requirements for Portuguese B2B exporters: EORI registration, commercial invoices, proof of origin, Incoterms and export VAT treatment.

Key Benefits

Faster customs clearance

Complete, accurate documentation clears customs in hours. Missing or incorrect paperwork causes holds that delay your customer's goods by days.

0% duty with proof of origin

EU manufactured goods exported to FTA partners (UK, Switzerland, Japan, Canada, South Korea etc.) qualify for 0% import duty — but only with correct EUR.1 or REX origin declaration.

Zero-rated export VAT

Exports outside the EU are zero-rated for Portuguese IVA (23%) — you charge 0% and reclaim input tax. Correct documentation is required to substantiate zero-rating.

Approved Exporter status

Regular exporters can apply for Approved Exporter status — self-certify origin on invoices without obtaining a EUR.1 certificate for each shipment, saving time and cost.

EORI Number — What It Is and How to Get One

An EORI (Economic Operator Registration and Identification) number is a unique identifier for businesses that import or export goods in the EU. Portuguese exporters shipping outside the EU need an EORI number on all customs export declarations. Without one, your carrier cannot submit the electronic export declaration (ECS — Export Control System) on your behalf.

  • Format: PT + your NIF (tax number). Example: PT123456789.
  • Registration: apply online via the Portuguese Customs Authority (AT — Autoridade Tributária e Aduaneira) at eori.at.gov.pt. Free. Usually activated within 1–3 business days.
  • Who needs it: any Portuguese business exporting goods outside the EU (UK, USA, Brazil, Switzerland, etc.).
  • EU internal: EORI is not required for EU-to-EU shipments (no export declaration needed within the EU single market).
  • Share with your carrier: provide your EORI number when setting up your shipping account. The carrier's customs brokerage team needs it for export declarations.

The Commercial Invoice — What Must Be Included

The commercial invoice is the most important document in international shipping. It is the basis for customs valuation, duty calculation and VAT assessment in the destination country. A poorly completed commercial invoice is the most common cause of customs delays.

  • Shipper details: company name, full address (including Portugal), EORI number, NIF, contact name and email.
  • Consignee details: recipient company name, full address, local tax/VAT number (VAT number in EU, EIN/FEIN in USA, CNPJ in Brazil etc.).
  • Description of goods: specific, accurate description of what the goods are — not 'parts', 'samples' or 'goods'. Example: 'Ceramic bathroom tiles, 30×60cm, white, decorative use'.
  • HS code (Harmonised System code): 6-digit HS code minimum — 8 digits for EU export declarations. Look up at hstool.wcoomd.org or via AT customs tariff.
  • Quantity and unit of measure: e.g. '24 units', '5 kg', '2 cartons of 12 bottles'.
  • Unit price and total value in currency: EUR is standard for Portuguese exports. Use actual transaction value — do not under-declare.
  • Country of origin: where the goods were manufactured, not where they are shipped from. Essential for FTA duty preference claims.
  • Incoterm: e.g. DAP Dublin, DDP New York, EXW Lisbon — states who is responsible for shipping costs and customs at each stage.
  • Reason for export: 'Commercial sale', 'Warranty replacement', 'Sample — no commercial value' etc.

Proof of Origin — EUR.1 Certificate and REX

Many of the EU's trade partners have Free Trade Agreements (FTAs) that allow 0% or reduced import duty on goods of EU origin. To benefit from these preferential rates, you must prove the goods originate in the EU with an origin document. Without proof of origin, your customer pays full MFN (Most Favoured Nation) rates.

  • EUR.1 Movement Certificate: issued by Portuguese customs (AT) for each shipment. Bring your commercial invoice and proof of EU manufacture to a customs office. Take 30–60 minutes. Cost: €20–€30. Valid for the UK, Switzerland, Norway, Turkey, Jordan, Egypt, Morocco, Tunisia and others.
  • REX (Registered Exporter): self-declaration of origin on the commercial invoice. Available once you register as a REX exporter with AT (free). For shipments over €6,000 (under that, a simple origin declaration on the invoice is enough without REX). Used for: Japan (JEEPA), Canada (CETA), South Korea (KOREU), Vietnam (EVFTA), Singapore and others.
  • Statement on origin: for shipments under €6,000 to FTA partners — simply include 'The exporter of the products covered by this document declares that, except where otherwise clearly indicated, these products are of EU preferential origin' on your invoice.
  • Origin criteria: goods must meet the relevant Rules of Origin under each FTA — typically 'substantially transformed' in the EU or meeting a specific change of tariff heading or value-added threshold. Your trade lawyer or customs agent can confirm if your product qualifies.

Export VAT — How Zero-Rating Works

Goods exported from Portugal outside the EU are zero-rated for IVA (Article 14 of the Portuguese VAT Code / Código do IVA). This means you charge 0% IVA on the commercial invoice for export sales — but you can still recover input VAT paid on your costs. Zero-rating is not automatic: you must have supporting export documentation.

  • Charge 0% IVA on export invoices (outside EU) — confirmed by Article 14(1)(a) CIVA.
  • Retain proof of export: customs export declaration (EAD — Exportation Accompanying Document) or carrier proof of delivery outside EU. Essential for AT audit defence.
  • EU B2B (reverse charge): for sales to EU businesses with valid VAT numbers, supply is 0% IVA under reverse charge (Article 6 CIVA). Include customer VAT number on invoice.
  • EU B2C: if you sell B2C to EU consumers and your total EU cross-border B2C sales exceed €10,000/year, register for OSS and charge destination country VAT rate.
  • Distance sales exemptions: professional export to UK requires UK VAT registration or IOSS/OSS equivalent — get advice from a tax advisor familiar with UK and EU VAT rules.

Incoterms — Choosing the Right Terms for B2B Exports

Incoterms (International Commercial Terms, published by ICC) define where the seller's responsibility ends and the buyer's begins — for cost, risk and customs obligations. Choosing the wrong Incoterm creates disputes and unexpected costs.

  • EXW (Ex Works): buyer collects from your factory. You have minimum obligation. Risk transfers at factory gate. Buyer arranges all transport and customs — complex for buyers unfamiliar with export procedures. Generally not recommended for international business.
  • DAP (Delivered at Place): you deliver to the named destination — buyer pays destination customs and import duties. Standard for most B2B international exports where buyer has customs infrastructure.
  • DDP (Delivered Duty Paid): you deliver to buyer's door, paying all costs including destination customs and import duties. Best buyer experience (no surprise customs bills) but you carry duty risk. Requires your own import customs registration in the destination country or a customs broker.
  • FCA (Free Carrier): you deliver to named carrier at your location. Risk transfers when carrier takes custody. Carrier then moves goods at buyer's risk and cost. Common for larger freight shipments.
  • CPT/CIP: you pay for transport to destination, but risk transfers at origin carrier handover. Used for air and multimodal freight.

Frequently Asked Questions

Do I need an EORI number to export from Portugal?

Yes — any Portuguese business shipping goods outside the EU requires an EORI number. It is mandatory for all electronic export declarations (submitted by your carrier or customs agent on your behalf). EORI is your business identifier in EU customs systems. Register free at eori.at.gov.pt — your EORI is simply 'PT' + your NIF. Activation takes 1–3 business days. Without an EORI, your carrier cannot submit the ECS (Export Control System) declaration and your shipment will be held at customs.

What happens if my commercial invoice is incorrect?

Customs authorities in the destination country can: hold the shipment pending corrected documentation (delays of 2–10 days), reassess the declared value and charge additional duties, confiscate goods if the documentation suggests misdeclaration (under-valuation, incorrect description). Common invoice errors: vague descriptions ('miscellaneous parts'), under-declared value, missing HS code, wrong country of origin. The carrier's customs broker cannot correct a fundamentally incorrect invoice — they can only work with what you provide. Review invoices carefully before each export.

How does Approved Exporter status work?

Approved Exporter (AE) status, granted by Portuguese Customs (AT), allows you to certify the origin of your goods directly on commercial invoices — replacing the EUR.1 certificate for each shipment. Instead of visiting a customs office for each EUR.1, you print an approved exporter origin statement on your invoice with your AT Authorisation Number. AE status is particularly valuable for businesses exporting regularly to UK, Switzerland and other EUR.1 destinations. Apply via AT — requires demonstrating knowledge of origin rules and agreeing to AT auditing. There is no fee. Processing takes 4–8 weeks.

Which Incoterm should I use for exports from Portugal?

For most B2B exports from Portugal: DAP (Delivered at Place) is the practical standard — you arrange transport, your buyer handles destination customs and pays import duties. DDP (Delivered Duty Paid) gives a better buyer experience but requires you to have customs import capability (or a broker) in each destination country. Avoid EXW for international shipments — it creates complications with export declarations (exporter of record obligations). For large freight: FCA named place (your warehouse) is common. Always confirm the agreed Incoterm in writing before booking the shipment.

How do I reclaim IVA on export shipments?

Portuguese IVA paid on costs associated with export production (raw materials, services, packaging) is recoverable as input tax on your quarterly Declaração Periódica do IVA. The output tax (IVA charged on sales) for export invoices is 0% (zero-rated). If your export business means you consistently have more input VAT than output VAT, you will be in a VAT repayment position — apply for refund on your IVA return. Retain all export documentation (commercial invoices, EAD export declarations, carrier receipts) for AT audit purposes — legally required for 10 years.
