Warehouse Management System (WMS) in Customs Warehouse – Requirements and Trends
What is a Warehouse Management System (WMS) in a Customs Warehouse?
Warehouse Management System (WMS) in a customs warehouse is a specialized software system designed for comprehensive management, control, and automation of all warehouse and logistics operations in an environment that is under customs supervision. In the conditions of the Czech Republic and the EU, a key requirement is ensuring full transparency and compliance with constantly changing customs regulations, including legislation governed by Customs Act No. 242/2016 Coll. (as amended effective 1.7.2025; source: dlprofi.cz).
Unlike a standard WMS, whose role is mainly to optimize the movement of goods, capacity, and inventory, WMS in a customs warehouse must also fulfill the role of a “digital guardian” of legislative correctness and audit traceability. The operator of a customs warehouse is subject to strict controls by the Czech Customs Administration and must demonstrate that every movement of goods – from receipt to dispatch and change of customs status – is precisely recorded, secured, and can be documented at any time.
Main Benefits and Importance of a Customs Warehouse with WMS
- Deferred Payment of Customs Duty and VAT: Goods can be stored without immediate payment of customs duties and taxes, which significantly improves company cash flow.
- Optimization of Logistics and Financial Flows: Possibility of planned release of goods into free circulation.
- Increased Flexibility in Inventory Management: Companies can dynamically respond to changes in demand, seasonality, or customer needs.
- Minimization of Error and Loss Risk: Automated records and control mechanisms significantly reduce the risk of errors, fines, and potential loss of operating license.
Permit for Operating a Customs Warehouse and Legislative Requirements for WMS
Customs Warehouse Permit
Operating a customs warehouse requires a formal permit from the Czech Customs Administration. This permit is issued on the basis of administrative proceedings, which includes, among other things, an assessment of technological infrastructure, security, and the system for recording goods (WMS). The main requirements that an applicant must demonstrate include:
- Security and Protection of Premises (e.g., physical security, camera and access system).
- Technological Infrastructure: A demonstrably functional and auditable goods recording system (WMS) that is capable of recording and maintaining all movements of goods under customs supervision in real time.
- Personnel Security: Professionally qualified personnel trained in customs matters, capable of operating the WMS and communicating with customs authorities.

Legislation and Standards
According to the currently applicable Customs Act (§242/2016 Coll., as amended effective 1.7.2025), the operator of a customs warehouse is obliged to ensure:
- Full recording and traceability of goods in a system that is resistant to retroactive changes (so-called immutability of records).
- The ability to immediately provide data to customs authorities in electronic form.
- Data retention for audit purposes for a specified period (usually 10 years).
- Integration with electronic systems of the Czech Customs Administration, in particular for submitting electronic customs declarations.
Key Requirements for WMS in a Customs Warehouse
Detailed Records and One Hundred Percent Traceability
Modern WMS for customs warehouses must enable:
| Function | Description |
|---|---|
| Goods Identification | Recording of all mandatory data – HS code, origin, customs value, quantity, weight, packaging, transport document number (T1, CMR, etc.). |
| Status Monitoring | Distinction of EU/non-EU goods, current customs status (temporary storage, storage regime in customs warehouse, active processing traffic, etc.). |
| Movement History | Record of every movement (receipt, transfer, storage, dispatch) with timestamp, user ID, and possibly physical location within the warehouse. |
| Data Immutability | The system must technically prevent retroactive modifications of records (audit trail, blockchain, or similar technology). |
Integration with Customs Systems
Fundamental requirements arise not only from Czech legislation but also from European regulations:
- Automatic Generation and Submission of Electronic Customs Declarations (e.g., JSD) directly from WMS to the Customs Administration system.
- Processing of Responses and Decisions of Customs Authorities: Automatic blocking/unblocking of goods according to received decisions.
- Possibility of Direct Connection to National and European Customs Portals (e.g., e-Customs, NCTS for transit regimes).
Management of Customs Regimes
WMS must be able to manage and record various customs regimes:
| Customs Regime | Recording Specifics |
|---|---|
| Storage in Customs Warehouse | Mandatory monitoring of deadlines, precise separation from goods in other regimes. |
| Temporary Storage | Strict monitoring of the 90-day deadline, automatic warning of approaching expiration. |
| Active Processing Traffic | Recording of processing operations, material output and consumption, retroactive calculations. |
Precise Inventory Management Under Supervision
Modern WMS must:
- Strictly Separate Inventories in free circulation from inventories under customs supervision, even when physically stored together.
- Support Customs Inventories: Enable regular and random inventories according to Customs Administration methodology, compare physical status with system records.
- Ensure Quick Response to Customs Control Requests: Possibility of immediate output of overviews, exports, and audit trails.
Reporting and Audit Trail
WMS must enable:
- Automatic and ad-hoc generation of inventory status reports for the customs administration.
- Export of audit records of all operations, including user access, changes, and handling steps.
- Retention of all data for the period specified by legislation (usually 10 years).
How WMS Works in a Customs Warehouse: Course of Operations
Typical Process Scenario in a Customs Warehouse with WMS
- Receipt of Goods into Warehouse
- Warehouse worker scans transport documents (T1, CMR, invoice, packing list).
- WMS assigns the goods a unique identifier, records all mandatory data, and suggests a storage location according to customs status and goods properties.
- A check of compliance of declared data with customs administration requirements is automatically performed.
- Storage (Put-away)
- The system specifies the exact location within the warehouse to the operator, often with regard to separation of regimes (customs supervision vs. free circulation).
- Confirmation of storage is immediately recorded in the system including timestamp and user.
- Online Inventory Management
- WMS provides a current overview of all inventories, enables planning of customs management, identifies approaching deadline expirations, and generates alerts.
- Order Processing and Customs Management (Order Fulfillment)
- The system allocates goods based on customer request and determines whether a customs declaration is necessary.
- In case of dispatch outside free circulation, WMS generates and electronically submits a customs declaration, blocks dispatch until receipt of customs authority decision.
- After approval, WMS issues a picking instruction, generates dispatch and transport documents, and enables connection to TMS for transport planning.
Why is This Process Crucial?
- Minimization of Human Errors: Every step is controlled by the system, reducing the risk of mistakes.
- Speed and Flexibility: Electronic communication with customs authorities accelerates management and clearance of shipments.
- Compliance with Audit Requirements: Every operation is traceable and immutable.
