When documentation fails, even compliant medical devices can be delayed at Turkey customs.

Why Medical Devices Get Stuck in Turkey Customs

Real-World Reasons Manufacturers Often Overlook

Many medical device manufacturers entering the Turkish market face an unexpected situation. Their products are CE marked, compliant with EU regulations, and already sold across Europe. Yet, when it comes to Turkey, shipments are delayed at customs and registration processes slow down.

The natural assumption is that something must be wrong with the product. In reality, this is rarely the case.

In Turkey, delays are usually caused by documentation not by product quality.

Turkey’s medical device system appears clear and structured on paper. However, in practice, small inconsistencies between documents can quickly turn into serious obstacles during customs clearance and UTS (Product Tracking System) registration.

Based on real cases from the field, the most common reasons are outlined below.

Country of Origin Has Become a Critical Issue

One of the most frequent causes of delays today is country of origin information.

A typical scenario looks like this: the product is manufactured in China, while packaging or labeling is performed in the European Union. The problem arises when the country of origin declared in the UTS system does not fully match the information stated in the customs declaration.

Once this mismatch is identified, the process comes to a halt. The registration does not move forward until the inconsistency is corrected.

Many manufacturers assume that “Assembly in EU” can be declared as the country of origin. In practice, this assumption often leads to delays, repeated corrections, and additional reviews.

CE Marking Is Necessary but Not Sufficient

CE marking is essential for entering the Turkish market, but it is not sufficient on its own.

In Turkey, authorities also examine UTS registration data, consistency between labeling and IFUs, and how documents align with local regulatory practices. As a result, files that pass smoothly in EU member states may still require revisions in Turkey.

This often surprises manufacturers entering the Turkish market for the first time.

IFU Translations Are Frequently Underestimated

Instructions for Use are another area where delays commonly occur.

In many submissions, IFUs are machine translated or prepared without sufficient attention to medical terminology. Even when the language appears correct, the medical meaning may be unclear or inconsistent.

Authorities rarely state that a translation is incorrect. Instead, they request clarifications or revisions, which slows the overall process and extends timelines.

In Turkey, IFUs are treated as professional medical documents and reviewed accordingly.

Labeling, UDI and Registration Data Must Align

Label information, UDI data, and UTS records must be fully consistent.

Common issues include incorrect UDI formatting, confusion between reference numbers and barcodes, or label statements that do not appear in IFUs or registration records. Individually, these issues may seem minor. Combined, they often trigger re-evaluation and delay.

Relying Entirely on the Distributor Is Risky

Another recurring issue is leaving the entire process to the local distributor.

In practice, this often results in documents being uploaded incorrectly, mistakes being identified too late, and manufacturers being informed only after delays have already begun. At that stage, both time loss and additional costs are difficult to avoid.

A Case from the Field

In one recent case, a UTS registration was delayed for several months solely due to a country of origin mismatch. There were no technical issues with the product and no deficiencies in CE documentation.

The delay was caused entirely by inconsistent registration data.

Final Thoughts

Turkey is not a difficult market to enter. However, it is unforgiving when it comes to details.

Most customs and UTS-related delays can be avoided when documentation is aligned from the beginning, regulatory requirements are reviewed holistically, and the process is actively managed rather than assumed to be “handled.”

In Turkey, product quality matters but documentation determines how fast a product reaches the market.
