Customs Clearance in Switzerland
Switzerland Runs Its Own Customs System
Switzerland is not in the EU customs union. Every commercial consignment entering the country is a genuine import that must be declared to the Swiss authorities — under Swiss law, through a Swiss system, against a Swiss tariff.
That means the EU constructs importers may be used to elsewhere in Europe — TARIC codes, the EU Common Customs Tariff, EU EORI numbers, the EU VAT Directive — are not the operative framework here. Switzerland has its own equivalents, and using the wrong one is a common source of delay.
The Authorities and Systems
| Element | Swiss equivalent |
|---|---|
| Customs authority | FOCBS / BAZG — Federal Office for Customs and Border Security |
| Declaration system | e-dec (electronic customs declaration) |
| Customs tariff | Tares |
| Importer identifier | UID number (Unternehmens-Identifikationsnummer) — not an EU EORI |
| Assessment document | Veranlagungsverfügung (DV) |
| Deferred payment | ZAZ centralised account |
The Clearance Process, Step by Step
- Documents are prepared. Commercial invoice, packing list, transport document (bill of lading, air waybill or CMR), certificate of origin where preference is claimed, and any import licence for restricted goods.
- The declaration is lodged in e-dec. The declarant enters the Tares tariff number, the value of the goods in CHF, gross and net weight, country of origin, the Incoterm, and the importer's UID.
- The system calculates duty and import VAT based on the declared tariff classification and the taxable amount.
- FOCBS issues the assessment decision (DV) setting out what is due. This document is the formal basis for input tax recovery, so it must be retained.
- Payment is made at clearance, or deferred through the ZAZ account which typically settles around 60 days after import.
- Goods are released and move to final delivery.
Required Documents
| Document | Required | Notes |
|---|---|---|
| Commercial invoice | Always | Must show value in a stated currency, product descriptions, Incoterm and origin |
| Packing list | Always | Gross and net weights, dimensions, package count |
| Bill of lading / air waybill / CMR | Always | Transport document matching the consignment |
| Certificate of origin | Where preference claimed | Needed to access preferential tariff treatment |
| Import licence | Restricted goods only | Applies to specific controlled categories |
Common Causes of Delay
- Incorrect Tares classification. The tariff number drives duty, VAT treatment and regulatory checks. Wrong classification is the single most common cause of assessment problems.
- Incomplete or inconsistent valuation. Swiss import VAT is assessed on value plus transport to the Swiss border plus insurance plus duty. Declaring a value that omits transport understates the taxable amount.
- Missing UID. Without a valid importer identifier the declaration cannot be completed normally.
- Absent certificate of origin where preferential treatment is expected — the preference simply will not apply.
- Restricted goods without a licence. Certain plants, animals, weapons, pyrotechnics, medicines, cash and counterfeit goods are prohibited or restricted.
Where Clearance Happens
For sea cargo arriving through a European gateway port, a decision has to be made: clear at the gateway under a transit procedure, or move the goods to Switzerland and clear on arrival.
Clearing in Switzerland tends to keep the VAT computation aligned with how Swiss import VAT is actually assessed — on value plus transport to the Swiss border. It also keeps the assessment decision in the Swiss importer's hands, which matters for input tax recovery.
Frequently Asked Questions
Swiss customs is administered by FOCBS / BAZG, the Federal Office for Customs and Border Security. Commercial imports are declared electronically through the e-dec system, usually by a declarant or forwarding agent acting for the importer.
The core set is a commercial invoice, a packing list, a transport document such as a bill of lading, air waybill or CMR, and a certificate of origin where preferential tariff treatment is claimed. Restricted goods may also require an import licence.
The assessment decision, known as the Veranlagungsverfügung or DV, is issued by FOCBS after the declaration is assessed. It sets out the customs duties and import VAT due and serves as the voucher supporting input tax recovery.
