1. Risk-Oriented Approach in Customs Controls
The customs audits are not just about checking the declaration information.
After check and reevaluate past transactions thanks to secondary control mechanisms. In these reviews, relations between customs declarations and commercial documents, accounting records and other related information may be significant.
According to the data described by the Ministry of Commerce on October 30, 2026, the secondary control performed in the first nine months of the 2026 and the post-clearance audit activities as a result of the total total 11,7 billion TL additional compensation and penalty decision arranged.
This amount shows the financial importance of customs and foreign trade compliance in terms of companies. However, the total is not a distribution that a particular type of risk is seen more often than others.
The purpose of risk management in terms of companies is to create controls not only reduce the possibility of audit, to continuously secure the compliance of the legislation of transactions.
2. GTIP and Tariff Classification Risks
GTIP is one of the most basic technical elements of customs clearance.
Classification of a goods in the wrong tariff position can lead to incorrect determination of taxes, additional financial obligations or external trade policy measures to be applied.
Among the circumstances that may lead to the occurrence of tariff risk in companies;
- direct use of HS code reported by supplier,
- the technical characteristics of the product should not be sufficiently examined,
- continued to be used without querying the GTIP determined in the past,
- despite the change of product properties, the classification should not be updated,
- documenting the technical and legal basis of the classification
There is.
The main risk is that a single product is not incorrectly classified, the company’s product’s main data is settled.
Therefore, GTIP controls should be carried out on product-based, risk-based and regularly.
3. customs value Risks
Customs clearance is a critical element in determining financial obligations to be applied in import operations.
The assumption of the customs asset is not correct, only in the case of the commercial invoice.
The elements that must be added to the asset according to the conditions of the somut process, or also have to be evaluated.
Specifically;
- royalty and license fees,
- die, design, engineering and so on additives,
- sales commissions and other related payments,
- processes between associated companies,
- price corrections and payments made after,
- transportation and insurance expenses
can pay attention to customs clearance.
The effect of these elements to the customs asset should be assessed by taking into account the specifications of the relevant legislation provisions and concrete processing.
It is one of the important control vulnerabilities that some payments in financial and purchasing systems of companies are not associated with customs clearances.
4. Import and preferential trade Risks
The origin of goods is important in terms of trade policy measures and preferred tax applications that can be applied.
It is necessary to not be mixed together with which country origin, especially with which goods are shipped from which country.
Among the situations that may pose a risk;
- the accuracy of proof origin documents should not be controlled sufficiently,
- incorrect interpretation of the rules of origin,
- not correcting supplier statements,
- mixing free circulation status with origin,
- not associated with the processing of origin documents
You can take place.
For example, A.TR is not correct to evaluate the roaming document as a document that proves the preferential origin of goods alone.
The provisions of the trade agreement on the controls of origin should be addressed together with the production process of goods and the rules of origin to be applied.
5. Risks on Foreign Trade Policy Measures
Only the correct calculation of customs tax in import operations may not be enough.
Different foreign trade policy measures may occur in accordance with the GTİP, origin, nature and relevant regulations of the item.
Among them;
- anti-damping taxes,
- protection measures,
- surveillance applications,
- additional customs duties,
- import permissions,
- product safety and compliance regulations
can be found.
It is important to re-evaluate these obligations during the period where companies started to work with new products, new suppliers or new country of origin.
In the time of regulatory changes, it can also cause a pre-existing process to become incompatible later.
6. Risks on special customs procedures
The processing, temporary import, antrepo and other special customs regimes can provide important operational and financial possibilities to companies.
However, these regimes also require the fulfillment of certain obligations.
For example, in the processing regime;
- follow-up of imported goods under regimen,
- production and consumption records,
- equivalent goods applications,
- export commitments,
- time and closing operations
is important control areas.
In such regimes, it is necessary to support not only the accuracy of the declarations, but the full records of the activities carried out under the regime.
7. Inconsistencies Between Accounting and Customs Records
One of the areas where companies can often be overlooked while evaluating the customs risks is consistency with each other of the records held in different departments.
Customs clearance can be held by foreign trade or logistics department while the payment and cost records can be kept in the financial unit.
Due to this decomposition;
- additional payments that are not included in the customs declaration,
- then the price difference invoices,
- supplier loans and inconto applications,
- service and license contracts,
- differences between accounting and import records
may not be judged on time.
Every record difference does not mean direct legislation. However, it is important that differences are explained and documentable.
An effective customs control system should be set up a traceable relationship between the financial records of the company with customs declaration.
8. Why Does Systematic Errors Create Larger Risk?
The error made in a single declaration may lead to limited results with concrete processing.
However, the company’s standard application of the same error can turn into an impact on past operations.
For example, using the wrong GTIP in a certain group of products, or systematic attention of an asset may affect a large number of import processes.
Therefore, not only the presence of error in risk assessment;
which date of error has been continued,
how many processes affect,
which is associated with products and suppliers,
What is the probable financial effect
⁇
there is no control to prevent the error again
should also be evaluated.
This approach is the basis of transition from transaction-based control to corporate risk management.
9. How To First Be The Customs Risks?
All customs clearance of the companies may not always be efficient at the same level of detail review.
Three basic sizes are available for priority in risk-based assessment:
Probability: The possibility of a certain non-compliance.
Effect: Financial, legal and operational results of non-compliance.
Control efficiency: Ability to prevent the risk of existing controls or detect in time.
These trading volume, past findings and legislation changes can also be added.
For example, if there is no classification base in a product group with high import volume, it can be examined more primary than a low volume and strong documented process.
This assessment is not an absolute legal result, but an administrative method that allows in-house control resources to be directed towards the right areas.
C-INSPEC PERSPEECTIVE
No Customs Risks Started in Declaration
The customs clearance in companies is often associated with the correct preparation of the customs declaration.
Yet an important part of the data used in the declaration occurs in the previous business processes.
The technical definition of the product comes from the engineering or product management unit, price and contract conditions purchasing department, payment and cost information finance unit, origin and shipping documents from the supply chain.
So the main reason for a non-compliance seen in the customs declaration may be realized very first from the preparation of the declaration.
An important part of the customs risks becomes visible during the process, but decisions that make these risks are often taken before the procedure.
For this reason, customs compliance in the C-INSPEC approach is not limited only by declaration control.
Product management, purchasing, foreign trade, finance, accounting and internal audit processes must also be evaluated.
The basic questions you need to ask for the upper management itself are:
- Who is the owner of customs risks in the company?
- Is customs compliance evaluated in new product and supplier decisions?
- Are customs declarations regularly compared with financial records?
- Does regulatory changes be transferred on time to operational processes?
- Are there risk-based internal audits on past transactions?
- Is the detected risks reported at the management level?
A strong customs compliance system is the system that only detects errors, improves processes that cause errors to occur.
10. Customs Risk Management Road Map For Companies
A five-stage structure can be recommended for companies who want to manage their customs risks systematically.
1. Establishing process and data inventory
Products, suppliers, countries, customs regimes and processing volumes are classified.
2. Determination of risk areas
Basic risks are detected in terms of tariff, asset, origin, foreign trade policy and regime obligations.
3. Risk based control and sample review
By selecting primary processes, declarations, technical documents, contracts and accounting records are compared.
4. Evaluation of findings and financial effects
The specified incompatibility is reported with legal basis, probable effects and corrective activity needs.
5. Continuous monitoring and reporting to management
The responsible for the controls are determined; risk indicators and regular reporting mechanisms are created.
This structure aims to carry the customs clearance into the enterprise management continuously from periodic inspection preparation.
Frequently Asked Questions
What risk areas are important in customs audits?
GTİP can be evaluated among the basic risk areas of customs clearance, origin, foreign trade policy measures, special customs regimes and consistency of commercial-mali records.
Why is the wrong GTIP use risky?
The wrong tariff classification can lead to incorrect determination of taxes and foreign trade policy measures to be applied. The use of the same code in a large number of transactions can lead to the risk to be increased.
How does customs clearance pose risks?
Some payments associated with the import process may arise due to the correct evaluation of elements that may affect the asset. The valuable effect of each element should be determined in the concrete process and legislation framework.
Can accounting records be reviewed in customs audit?
Yes. According to the scope of the audit, commercial and financial records, payment documents, contracts and other related information may be examined.
How can companies reduce customs risks?
Risk-based internal controls, regular trading reviews, accurate product main data, legislation tracking and data consistency between departments, and pre-determining and management of risks can be supported.
Is the customs risk management solely responsible for the foreign trade department?
No. Different functions such as purchasing, finance, accounting, product management, law and internal audit can have effect on customs compliance. It is important to clearly identify the responsibilities.
Conclusion
An important part of the risks that may arise in customs audits is directly associated with the daily business processes of companies.
False tariff classification, missing asset assessment, errors in origin applications, or inconsistencies, should not only be seen as a problem of a particular declaration.
Such risks provide important indicators about the effectiveness of the company’s internal control and enterprise compliance system.
The success of customs compliance is not measured only as a result of audit. The main success is that risks are detected before auditing and managed in a sustainable way.
