Corporate Defence in German Customs Audits

By Dr. Julius Hagen, Attorney at Law

Defence at the interface of customs audits, corrections and criminal proceedings

German customs may request commodity codes, customs values, preference documents, delivery terms, ATLAS data or communications with freight forwarders and customs agents. For the company, the immediate concern is often an additional duty assessment. From a criminal defence perspective, the risk arises when the authority does not only identify an error, but asks why it happened and who was responsible.

At this stage, companies often continue to communicate as if the matter were still only a technical clarification with the customs office.

The situation becomes more exposed where earlier warnings from customs, repeated similar mistakes or internal emails suggest that the inaccuracy was known. The same document may then have two meanings. For customs purposes, it explains a discrepancy. In criminal or regulatory proceedings, it may be read as an indication of intent, recklessness or a failure of supervision.

Cooperation duties and self-incrimination risk

In the customs and tax procedure, companies have duties to cooperate. They must provide documents, explain facts and assist in determining the customs and tax basis. In criminal proceedings, individuals are protected against self-incrimination. This overlap makes customs audits risky when the same authority investigates duties and also collects indications for a criminal or regulatory case. The most common mistake is not providing documents. The real risk is explaining causes, knowledge and responsibility before it is clear whether the authority is already thinking in criminal terms.

This can arise when a company is asked to explain understated customs values, when preference documents later become doubtful or when a transit procedure was not properly discharged. A technical explanation may be necessary for customs purposes. The same explanation may later support an allegation that the persons involved knew of the error, accepted it or failed to supervise the process properly.

How German customs reads audit findings

The authority will rarely rely on a single error. More often, it assesses customs declarations, invoices, emails, freight documents, delivery terms, product descriptions, payment flows, service provider data, work instructions and earlier audit findings together. From this record, it may infer an isolated operational mistake, a repeated incorrect practice or a structural compliance failure.

An objectively incorrect customs declaration is not yet a complete criminal allegation. It initially shows only that information was wrong – not who caused the error, recognised it or adopted it without proper review. A subsequent customs debt does not prove intent. Unclear internal responsibility may reveal a process risk, but it does not automatically establish personal criminal liability.

Customs evasion, recklessness or corporate supervision failure

The direction of the case often depends on the mental element and the company’s responsibility structure. Customs evasion under German law requires intentional incorrect or incomplete information on tax-relevant facts. A reckless tax understatement does not require intent, but it requires a serious breach of care. In corporate cases, the authority may also consider regulatory fines if it believes that management or supervisory duties were violated. Even well-intended corrections can become problematic if they explain more than is required from a customs and tax perspective.

A managing director who was not involved in operational customs declarations is in a different position from a customs officer who approved commodity codes, preference documents or customs values. A logistics provider relying on client data is in a different position from an importer who supplied incorrect invoice values. It must be reconstructed who had which information, who made which decision and whether the documents actually support a criminal inference.

Typical risk areas in corporate customs cases

In tariff classification, an incorrect commodity code may first look like a technical classification error. The criminal assessment changes if the authority argues that the correct classification was known because of earlier customs rulings, internal warnings or clear product documentation.

In customs valuation, licence fees, tooling costs, freight costs, related-party transactions or discounts may affect the calculation of import duties. If contracts or payment flows suggest that relevant value components were deliberately omitted, the case may move toward an allegation of customs evasion.

For preference documents and origin declarations, the duty burden often depends on whether the origin of the goods is properly documented. If that documentation later collapses, the key question is whether proof is merely missing or whether the persons involved already had doubts about origin when the declaration was made.

Corrections and criminal communication

After audit findings, the company may need to decide whether to file a correction under Section 153 of the German Fiscal Code. A correction may be required from a customs and tax perspective. At the same time, it may confirm that earlier declarations were incorrect. The risk increases when a correction not only adjusts figures, but also describes causes, responsibilities or knowledge within the company.

Before filing a correction, it should be clear whether there is already an initial suspicion, which individuals may be affected and which statements go beyond the objective correction required. In many cases, the central criminal risk is not the payment of additional duties itself. It lies in how the error is explained.

When technical correction and defence diverge

Customs audits often involve tax advisers, customs advisers, freight forwarders, customs agents and internal customs staff at the same time. This division of work is necessary. It becomes risky when the tax adviser resolves the duty issue, the customs adviser formulates the technical correction and no one assesses the criminal law message created by that correction. A correction that makes sense from a customs perspective may be problematic in criminal law. A technical explanation from a customs adviser may unintentionally suggest that the error had been recognisable internally for some time.

Communication should therefore be structured before statements, corrections or internal cause reports are submitted to the authority. Where external service providers are involved, it matters whether the error originated from incorrect company data, from the customs agent’s handling or from an unclear interface. In criminal law, the issue is not only which declaration was wrong, but who caused, reviewed or adopted the incorrect content.
