Penalty Interest

Penalty interest is a common default remedy clause in foreign trade contracts. It refers to additional interest calculated on the overdue amount at an agreed interest rate or penalty rate when one party fails to fulfill its payment or repayment obligation as agreed. It is commonly seen in scenarios such as letters of credit, documentary collections, open account (O/A), buyer's credit, and deferred payment, especially when the buyer delays payment of goods, advance payment, or balance payment, the seller or bank may claim penalty interest. Its core function is to compensate for the loss of capital occupation and urge performance. Notes: The penalty interest rate is usually higher than the normal interest rate, but must not violate applicable laws regarding interest rate caps (such as the judicial protection upper limit for private lending rates in China); the contract should clearly specify the start date of penalty interest, calculation base, interest rate standard, and whether compound interest applies. Unlike 'late payment fees', penalty interest focuses on compensation for the time value of funds, while late payment fees are more oriented toward administrative or utility charges; unlike 'liquidated damages', penalty interest is usually calculated continuously based on the number of overdue days, while liquidated damages may be a one-time fixed amount. Foreign trade practitioners should clearly stipulate penalty interest clauses in contracts and pay attention to differences in the enforceability of penalty interest across different jurisdictions.
