The authority issued a public notice informing businesses, government agencies, and members of the public about the planned interruption, which is expected to last for 36 hours.
According to the statement released on Friday, February 6, 2026, the system will be unavailable starting at 6 pm on Saturday, February 7, 2026.
The maintenance exercise is expected to be completed by 6 am on Monday, February 9, 2026.
During this period, several customs-related services handled through the platform will be temporarily affected.
The iCMS is an important digital platform used by KRA to manage customs operations across the country.
The system supports various processes, including cargo clearance, collection of customs revenue, and coordination of cross-border trade activities at ports of entry such as airports, seaports, and border points.
Many importers, exporters, clearing agents, and shipping companies depend on the system to process goods and complete documentation required for trade.
In its notice, KRA explained that the maintenance is necessary to improve the system’s performance, reliability, and security.
The authority said such upgrades are part of efforts to ensure that customs services remain efficient and able to support the growing volume of trade activities in the country.
“We wish to inform partner government agencies, importers, exporters, clearing agents, shipping lines, and the general public of scheduled major maintenance for the iCMS,” KRA said in its statement.
KRA urged stakeholders who rely on the platform to plan their activities in advance to avoid delays or inconveniences during the maintenance period.
Businesses involved in import and export operations have been advised to process urgent transactions before the system goes offline or wait until services are fully restored.
Trade experts say that temporary system shutdowns are common in digital platforms, especially when authorities are upgrading systems to improve efficiency.
They note that regular maintenance helps prevent system failures, reduces the risk of cyber threats, and ensures smooth operations in the long run.
However, some business operators have expressed concern about possible delays in cargo clearance and movement of goods during the maintenance period.
Clearing agents and logistics companies often work under tight schedules, and any interruption in customs services can affect delivery timelines and business operations.
Despite these concerns, many stakeholders acknowledge that system upgrades are necessary to improve service delivery.
KRA has assured users that all services will resume immediately after the maintenance exercise is completed.
The authority also encouraged stakeholders to stay updated through official communication channels in case of any changes or additional instructions during the maintenance period.
