The most common declaration errors — and how to prevent them
Even the smallest discrepancy in a declaration can turn into a duty difference and a penalty. Here are the errors brokers see most — and how to catch them before they reach customs.
GTİP / HS misclassification
Assigning the wrong GTİP leads to the wrong duty rate and surveillance/quota breaches. It is the most frequent — and often the most expensive — error.
Value (customs value) mismatch
A declared value that does not match the invoice, missing freight/insurance, or an exchange-rate difference can result in additional assessment and a penalty.
Gross/net weight and quantity
Weight and count differences between the packing list and the declaration cause problems during physical inspection and slow the process down.
Origin and document mismatch
A declared origin that conflicts with the A.TR, EUR.1 or certificate of origin can lead to the preferential tariff being rejected and a penalty.

FAQ
How big is a declaration-error penalty?
Penalties depend on the error type; value and GTİP errors can trigger additional duty plus a penalty under the Customs Law. Prevention is always cheaper than paying.
