Importing materials for production, parts for assembly or equipment for repair from outside the EU? We help prepare inward processing — from authorisation and customs declarations to records and discharge of the procedure.

WHEN SHOULD YOU DISCUSS THIS PROCEDURE?
Non-Union goods processed in the EU.
Inward processing is a special customs procedure. It allows non-Union goods to be imported for processing, such as machining, assembly or repair, subject to the procedure’s conditions. When goods enter this procedure, import charges are not collected as they would be on an ordinary release for free circulation. Subsequent settlement depends on the operations performed and the products’ destination.
Assembly and installation
Components used for assembly or installation in other goods. Quantities, identification and consumption accounting rules matter.
Repair and refurbishment
Non-Union goods imported for servicing. Before dispatch, we check equipment documentation, the work scope and the intended subsequent destination.
CONDITIONS AND PREPARATION
From authorisation to records and the bill of discharge.
Before the operation, we check documents and the implementation plan, identify points to clarify and prepare a service quote.
Authorisation suited to the operation
We describe the goods, processing locations and methods, and planned products. We check authorisation conditions, any guarantee and the appropriate application method. We agree the service scope before import.
Identification and rate of yield
Imported goods must be linked to processed products. The rate of yield describes the quantity or percentage of products obtained from a given quantity of materials. Consumption, waste and loss data should reflect the actual process.
IM/EX, EX/IM and equivalent goods
The usual sequence is import, processing and the products’ subsequent destination. Prior exportation or equivalent goods may be permitted under the authorisation’s conditions. We do not assume they are allowed without analysing the specific case.
Discharge and exchange of information
Preparing a customs declaration is only part of the service. We agree records, deadlines and the bill of discharge. The use of INF or other electronic information exchange depends on authorisation conditions and arrangements with customs.
CONSISTENT DATA IS ESSENTIAL
Production and customs records must describe the same operation.
We help plan records and link material imports to products, waste and subsequent customs declarations. If a product is intended for the EU market, we first establish release-for-free-circulation conditions and the appropriate calculation of charges. The basis is not always simply the finished product’s full value.

DOCUMENTS FOR FIRST CONTACT
Send what you already have.
You do not need to assemble everything before enquiring. Describe the operation and attach available materials. We identify missing documents and data needed for a quote.
We send an authorisation template after agreeing cooperation details and signing the contract. The signed authorisation is needed for customs clearance.
- Materials and productsDescriptions, CN codes, quantities, values and specifications of imported goods and processed products.
- Processing descriptionTechnology, operation locations, contractors, production or repair time, consumption rates and expected waste.
- Commercial documentsContracts, invoices, delivery terms and details of parties involved in the operation.
- Authorisations and existing recordsExisting authorisation, earlier customs declarations and discharge data if the procedure is already under way.

Inward processing in practice.
Must the products be re-exported outside the EU?
Re-export is one possible way to discharge the procedure. Another customs destination, including release for free circulation, may also be possible, with settlement of charges and fulfilment of the relevant requirements. We establish this in the service plan.
Does inward processing cover repairs?
Yes, repair can be a processing operation. The goods’ status and direction of movement matter: importing non-Union goods for repair in the EU differs from exporting Union goods for servicing abroad.
Do you help with records and discharge?
Yes. Our support can cover authorisation, record-keeping arrangements, customs declarations and discharge of the procedure. We agree the exact scope once we understand the process and available data.
Can authorisation be obtained through a customs declaration?
This is possible in cases provided for by the rules. Not every operation meets the conditions for this form of authorisation; we analyse this before import begins.
LET’S DISCUSS YOUR CASE
Inward processing – ask about support.
Describe the imported materials or equipment, processing scope, countries, dates and the products’ intended destination. Tell us whether you hold an authorisation.
Attach up to three PDF, JPG or PNG files, up to 5 MB each. Larger files can be sent later. We quote once we understand the scope.
