Customs paperwork explained for shippers

Why customs documentation matters when moving goods to and from France

Customs documentation is the paper trail that proves what you are shipping, who owns it, where it comes from and what it is worth. Whenever goods cross a border into or out of the European Union, authorities use these documents to calculate duties and taxes, apply the right controls and confirm that nothing prohibited is being moved. For a business in France, getting the paperwork right is not just a compliance formality: it directly affects how quickly your shipment clears and how much it ultimately costs.

When documents are missing, incomplete or inconsistent, goods can be held at the border while questions are resolved. That delay can mean missed delivery windows, storage charges at the port or airport, and unhappy customers. In some cases, incorrect declarations can lead to penalties or the reclassification of goods at a higher duty rate.

It helps to think of customs paperwork in two directions. Movements within the EU single market generally do not require customs declarations because goods circulate freely, though VAT and statistical reporting may still apply. Movements to or from countries outside the EU do require full customs formalities. Since a large share of French trade involves partners beyond the EU, understanding these requirements is essential for any shipper. The good news is that the documents themselves are standardised and predictable, so once you understand the logic behind each one, preparing them becomes a routine part of your shipping process.

Key parties and reference numbers: EORI, HS codes and Incoterms

Before you can complete any customs document, you need a few core reference points. The first is your EORI number, short for Economic Operators Registration and Identification. Any business established in France that imports or exports goods with non-EU countries must have one. It is a single identifier used across all EU customs systems, and it links every declaration you make to your company. Without it, you cannot lodge a customs declaration, so it is the natural first step for any new exporter or importer.

The second reference is the HS code, or Harmonised System code, sometimes extended in the EU as a combined nomenclature or TARIC code. This numeric code classifies your product and determines the duty rate, VAT treatment and any restrictions that apply. Choosing the correct code is one of the most important decisions in the whole process, because an error here changes the amount you pay and can trigger inspections. Take time to identify the code that genuinely matches your goods rather than guessing from a similar item.

The third element is the Incoterm, an internationally agreed three-letter rule that defines who is responsible for transport, insurance, export clearance and import clearance at each stage. Common examples include EXW, FCA, CPT, DAP and DDP. The Incoterm you agree with your trading partner determines who arranges and pays for customs formalities, so it should be written clearly on your commercial invoice. Getting these three elements aligned from the start prevents most confusion later.

Essential documents for exporting goods out of France

When you export goods from France to a country outside the EU, several documents typically travel with the shipment or accompany the customs declaration. The commercial invoice is the central document. It describes the goods, states the quantity and value, identifies the buyer and seller, and shows the agreed Incoterm and currency. Customs authorities rely on it to assess value, so it must be accurate and consistent with everything else.

Alongside the invoice, a packing list breaks down how the goods are physically arranged: the number of packages, their weights and dimensions, and what is inside each one. This helps both customs and the carrier verify the shipment without opening every box. You will also need the export customs declaration, lodged electronically, which formally notifies the authorities that goods are leaving the customs territory.

Depending on the product and destination, additional documents may be required. A certificate of origin proves where the goods were made and can help the buyer benefit from reduced duties under a trade agreement. Some goods need export licences, health or phytosanitary certificates, or dangerous goods declarations for regulated items. Transport documents such as an air waybill, bill of lading or CMR consignment note prove the contract of carriage. Preparing these in advance, rather than at the moment of dispatch, is the simplest way to keep your export moving smoothly.

Essential documents for importing goods into France

Importing goods into France from outside the EU mirrors the export process but from the receiving side. Again, the commercial invoice and packing list are fundamental, because French customs use them to determine the customs value on which duties and import VAT are calculated. The values and descriptions must match the goods that actually arrive, or the declaration can be questioned.

The import customs declaration is the key formality. It is submitted electronically and includes the HS classification, the declared value, the country of origin and the customs procedure being used. Based on this, the system calculates the duties and taxes payable before the goods can be released. Your EORI number identifies you as the importer of record, unless you have agreed for another party to take that role.

Supporting documents often accompany the import. A certificate of origin may be needed to claim a preferential duty rate under a trade agreement. Import licences or permits apply to certain categories such as food, chemicals, electronics or products subject to safety standards. Where relevant, conformity documents demonstrate that the goods meet EU requirements. Transport documents once more prove the carriage and the point of delivery. Keeping copies of everything is important, because customs may carry out post-clearance checks and expect you to justify your declaration for several years afterwards.

How customs declarations work in the EU and with non-EU countries

The way customs works depends heavily on whether your trade partner is inside or outside the EU. Within the single market, goods move freely between member states without customs declarations. There are no duties on intra-EU trade, and clearance formalities do not apply. However, VAT rules still govern the transaction, and businesses must report cross-border movements through periodic statistical and tax filings. So while it feels frictionless, there is still administrative reporting behind the scenes.

For trade with countries outside the EU, full customs procedures apply in both directions. Exports require an export declaration, and imports require an import declaration with duty and VAT assessment. Declarations are lodged electronically through the customs system, and goods are assigned a customs status until they are released. Different procedures exist for different situations, such as temporary admission for goods that will be re-exported, or transit procedures that allow goods to move under customs control from one point to another before final clearance.

Understanding which flow applies to each shipment helps you plan. A business that trades within the EU and also imports from further afield must handle two very different sets of obligations. Mapping your typical shipping routes and identifying which ones cross the EU border will show you where full customs paperwork is genuinely required and where lighter reporting is enough.

Common paperwork mistakes and how to avoid delays

Most customs delays come from a small number of recurring errors, and nearly all are preventable. The most frequent is an incorrect or vague product description. Writing simply "parts" or "samples" gives customs nothing to verify against the HS code, so descriptions should be specific about what the item is and what it is made of. Related to this is choosing the wrong HS code, which changes the duty rate and can flag the shipment for review.

Inconsistent values across documents are another common trap. If the commercial invoice shows one amount and the transport document or declaration shows another, customs will pause the shipment to reconcile the difference. The same applies to mismatched weights, quantities or party details. Every document should tell the same story.

Missing supporting documents cause avoidable holds, particularly certificates of origin needed to claim preferential duty, or licences for regulated goods. A missing or incorrect EORI number will stop a declaration entirely. Finally, an unclear Incoterm can leave both parties assuming the other is handling clearance, so goods sit at the border with nobody instructing the release. To avoid these issues, build a simple review step into your process: check that descriptions, values, codes and party details are consistent, that all required certificates are attached, and that the responsible party for clearance is unambiguous before the goods leave.

Working with customs brokers and freight forwarders

Many shippers, especially those new to non-EU trade or handling irregular volumes, choose to work with a customs broker or freight forwarder. A customs broker specialises in preparing and lodging declarations on your behalf, applying the correct classifications and procedures. A freight forwarder arranges the physical transport and often coordinates customs clearance as part of a wider logistics service. The two roles overlap, and some providers offer both.

Using a professional does not remove your responsibility as the trader. You remain accountable for the accuracy of the information you provide, so you should still understand your HS codes, values and origin. What a broker adds is expertise in the procedures, familiarity with the customs systems, and the ability to resolve issues quickly when questions arise. For businesses that ship regularly, this can save considerable time and reduce the risk of costly errors.

When engaging a provider, be clear about who is responsible for what. Confirm whether they will act as your direct or indirect representative, what documents they need from you, and how they will handle duties and VAT payment. Provide them with complete, accurate information from the start, because their declaration is only as good as the data you supply. A good working relationship, built on clear communication and reliable paperwork, makes the whole process far more predictable.

A practical checklist for preparing your customs paperwork

Turning all of this into a routine is easier with a simple checklist you follow for every shipment. Start by confirming the direction of the movement: is it within the EU or to and from a non-EU country? This tells you whether full customs formalities apply. Next, make sure your core references are ready: a valid EORI number, the correct HS code for each product, and a clearly agreed Incoterm with your partner.

Then assemble the core documents. Prepare a detailed commercial invoice and a matching packing list, and double-check that descriptions, values, quantities and party details are consistent across both. Identify any additional documents your specific goods require, such as a certificate of origin, licences, or health and safety certificates, and gather them before dispatch rather than after.

Finally, decide who will lodge the declaration and pay any duties and taxes, whether that is you, your partner or a broker acting on your behalf. Keep organised copies of every document, because customs can review declarations after clearance. Running through these steps consistently builds a reliable process that reduces delays, avoids surprises and keeps your goods moving. Over time, this discipline turns customs paperwork from a source of stress into a manageable, repeatable part of your shipping operation.

FAQ

Do I need an EORI number to ship from France? Yes, if you are moving goods between France and a country outside the EU, your business needs an EORI number. It identifies you across all EU customs systems, and you cannot lodge a customs declaration without one. It is not required for trade that stays entirely within the EU single market.

What is the difference between an HS code and an Incoterm? An HS code classifies your product for customs and determines the duty rate, VAT treatment and any restrictions. An Incoterm is a three-letter rule that defines who is responsible for transport, insurance and customs clearance at each stage. Both should appear clearly on your commercial invoice, but they serve very different purposes.

Do I need customs paperwork for shipments within the EU? Goods generally move freely within the EU single market without customs declarations, and no duties apply. However, VAT rules still govern the transaction and businesses may need to submit periodic statistical and tax reports. Full customs formalities only apply when goods cross the EU border to or from a non-EU country.

What causes most customs delays? The most common causes are vague product descriptions, incorrect HS codes, inconsistent values or details across documents, missing certificates or licences, and unclear Incoterms that leave clearance responsibility undefined. Reviewing your documents for consistency and completeness before dispatch prevents the majority of these problems.

Should I use a customs broker or handle paperwork myself? It depends on your volume and experience. A broker or freight forwarder brings expertise in procedures and can resolve issues quickly, which is helpful for regular or complex shipments. However, you remain responsible for the accuracy of the information you provide, so you should still understand your codes, values and origin regardless of who lodges the declaration.
