What Inward Processing is, in plain terms
Inward Processing is one of the EU's customs special procedures. Under the Union Customs Code (Regulation (EU) No 952/2013, Article 256), non-Union goods can be “used in ... one or more processing operations without being subject to ... import duty” or the other import charges. In practice that means a manufacturer or repairer can import raw materials, components or broken units from outside the EU, work on them, and re-export the finished products — without the import duty and import VAT ever being paid, provided the goods are re-exported. The duty and VAT are not waived; they are suspended, secured by a guarantee, until the procedure is discharged.
The two conditions: non-Union goods, processed in the EU
IP has a narrow scope, and both legs must hold:
- Non-Union goods — the goods are imported from outside the EU customs territory. Goods already in free circulation in the EU are not imported, so there is no import duty or VAT for IP to suspend.
- Processed in the EU — the goods undergo a processing operation: manufacture, assembly, working, or repair. Goods that are only stored or transited, not processed, belong under customs warehousing or a normal entry. Outside repair and destruction, Article 256(2) also requires that the imported goods can be identified in the processed products.
Re-export discharges the relief — free circulation triggers the debt
The whole basis for the suspension is that the goods leave the EU again. The procedure is discharged by re-exporting the processed products (or by placing them in customs warehousing or a free zone). On the share you re-export, the suspended duty and VAT never become payable. But if the processed products are instead released for free circulation in the EU, the suspended import duty and VAT fall due — calculated, under UCC Articles 85 and 86, either on the original non-Union goods or on the processed products at the time of release. That is why this tool asks for a re-export share: the part you keep in the EU is the part you pay on.
How the duty and VAT estimate works
The estimate is deliberately simple and transparent. The import duty is the customs value times the duty rate. The import VAT base is the customs value plus the duty (the duty is itself VAT-able), so VAT is charged on that combined figure, not on the bare value. The total of duty and VAT is then split by your re-export share: the re-exported part is what IP suspends, and the free-circulation part is what stays payable. The rates are your inputs — the duty rate comes from the EU tariff (TARIC) for your HS code, and the VAT rate is the standard rate of the Member State of import. No rate dataset is built in, because both vary by classification and country.
Authorisation, guarantee, bill of discharge
IP is not automatic. You need an authorisation from the customs authority of the Member State where you operate, which sets the period for discharge (Article 257). You provide a guarantee securing the potential customs debt (Article 89). When the period ends you submit a bill of discharge to the supervising customs office — in the UK's CDS that is Form BOD1 — reconciling what was imported against what was re-exported, warehoused, or entered for free circulation. Miss the discharge and customs issues a demand to pay the suspended duty and VAT. Article 258 also allows processed goods to be temporarily re-exported for further processing outside the EU under the outward-processing rules.
If Inward Processing does not fit
When the goods are not non-Union, or they are not actually processed, IP is the wrong route. Customs warehousing suspends duty and VAT on non-Union goods that are stored (not processed) and later re-exported or entered. A normal customs entry simply pays the import duty and VAT up front — the right choice when the goods are staying in the EU for good. IP earns its overhead only when non-Union goods are processed and a meaningful share is re-exported.
Frequently asked questions
Does Inward Processing suspend import VAT as well as duty?
Yes. Article 256(1) suspends import duty and the “other charges ... under other relevant provisions in force”, which the European Commission's guidance confirms includes import VAT and excise. Both are suspended while the goods are under the procedure, secured by a guarantee.
What happens if I sell the processed goods inside the EU?
Selling them in the EU means releasing them for free circulation, which discharges that share of the procedure by payment, not re-export. The suspended import duty and VAT then become payable, calculated under UCC Articles 85–86 on the original goods or the processed products.
Is the suspended amount this tool shows a quote?
No — it is an estimate from your own customs value and rates. The actual customs debt, the rate of yield, the method of calculation and the discharge are determined by the national customs authority on the IP authorisation.
Is anything I enter sent to a server?
No. The verdict and the estimate are computed entirely in your browser from the rules and formula described above. Nothing you enter leaves your device.
