Inward Processing: The Complete Guide to This Customs Regime

Every year, industrial companies pay customs duties on raw materials they import, process, and then re-export as finished products. These duties, which can represent tens of thousands of euros annually, are in fact avoidable. Inward processing is the customs regime that allows suspension or even cancellation of import duties and taxes when goods are destined for processing before being re-exported outside the European Union.

What is Inward Processing?

Inward processing (IP) is a special customs regime governed by the Union Customs Code (UCC, Regulation EU 952/2013, Articles 256 to 258). It authorises the import of non-Union goods onto the EU customs territory in total suspension of customs duties, VAT and excise duties, on condition that those goods undergo a processing, working or repair operation before being re-exported.

In other words, if you import components from a third country to manufacture finished goods destined for export, you do not have to pay import duties on those components. The customs obligation only arises if the processed goods ("compensating products") are ultimately placed on free circulation in the European market.

Important distinctions: outward processing works in mirror: you temporarily export Union goods to a third country for processing, then re-import them paying duties only on the value added abroad. Temporary admission allows the import of goods in duty suspension but prohibits any substantial processing — goods must leave in their original state. With inward processing, transformation is not only permitted, it is the reason for the regime.

Suspension or Drawback: Which Variant to Choose?

Suspension: The Default Choice

No customs duties or taxes are paid at the time of import. Goods enter the EU under a suspensive regime: the customs debt is frozen until compensating products are re-exported or placed on free circulation. If all processed products leave the EU, the suspended duties are definitively cancelled. This is the most common variant as it avoids any cash advance.

Drawback: A Strategic Alternative

Customs duties and VAT are paid normally at import as in standard free circulation. When compensating products are effectively re-exported, the company can request a refund of the duties paid. This variant is less common as it ties up cash upfront, but can be relevant when the re-exported share is uncertain at the time of import.

Impact on Your Cash Flow

During the regime, three types of levies are suspended: customs duties (calculated on the customs value according to the common customs tariff), import VAT, and excise duties where applicable. A practical example: a company imports €1,000,000 of raw materials subject to a 5% duty rate, meaning a potential customs debt of €50,000. If 75% of the processed products are re-exported, the exemption covers €37,500 in duties, and the company pays only €12,500 on the portion placed on the EU market.

Obtaining the Authorisation

Inward processing requires prior authorisation from customs authorities. To be eligible, your company must have a valid EORI number and be able to economically justify the use of the regime. Since 20 March 2023, authorisation applications are submitted via the TP-CDS European portal (Trader Portal - Customs Decisions System). Authorisation is in principle granted for 5 years.

A critical point: each application must also demonstrate that the authorisation will not prejudice the "essential interests of Union producers". The regime was suspended for sugar in January 2026 on this basis, as the beet industry demonstrated IP was generating unfair price competition.

Common Errors in Inward Processing

Approximate Material Accounting: The N°1 Trap

Material accounting is the most demanding obligation of the regime. It must enable the entire journey of each batch of imported goods to be traced, each transformation step to be documented, and the quantities of compensating products, waste and losses to be justified. Incomplete traceability exposes the company to a reassessment during a customs audit.

Late Discharge: The Scenario That Turns an Exemption into a Reassessment

The holder has a deadline set in the authorisation to discharge the regime. If this deadline is missed without the discharge account being filed within 30 subsequent days, the initially suspended customs debt becomes immediately payable, with late interest. In other words, the exemption retroactively becomes a debt.

Confusing Inward Processing and Temporary Admission

Temporary admission prohibits any substantial processing of goods. If you modify goods placed under temporary admission, you are in breach. Conversely, if you place goods under inward processing when they undergo no transformation, the regime is not justified. Both regimes suspend duties but their purpose is fundamentally different, and choosing the wrong regime can lead to penalties and recovery of suspended duties.

Frequently Asked Questions about Inward Processing

What is the difference between inward and outward processing?

Inward processing concerns the import of non-Union goods for processing in the EU before re-export. Outward processing works in reverse: you temporarily export Union goods to a third country for processing, then re-import them paying duties only on the value added abroad.

How long does it take to obtain an inward processing authorisation?

In practice, several weeks to several months between filing the application on TP-CDS and obtaining the authorisation. Starting early and filing a complete application from the outset is essential.

Is inward processing reserved for large companies?

No, the regime is open to any company with a valid EORI number and able to economically justify its use. However, the traceability and material accounting obligations represent a significant investment, making it more accessible to ETIs and large groups than to very small businesses.

What happens if some processed goods remain on the European market?

Customs duties only apply to the fraction of compensating products actually placed on free circulation in the EU. The re-exported portion remains totally exempt. Depending on the calculation method chosen (Article 86 UCC), duties can be calculated on the basis of imported raw materials or on the finished product, whichever is more advantageous.
