FROM APRIL 1, 2026: CUSTOMS AUTHORITY IMPLEMENTS UNIFIED UNIT CODE SYSTEM NATIONWIDE
This technical adjustment has a direct impact on customs declaration processes, especially during the transition period.
1. A Milestone in Customs Data Management
According to Notice No. 174/CNTT-QLVH, the Customs authority will standardize unit codes across all systems with the following objectives:
- Standardize data management across the system
- Enhance connectivity between IT systems
- Support the centralized customs clearance model
The new coding structure is based on the regional customs sub-department model, where each region includes:
- A headquarters code
- Clearance team codes assigned by province/city
This approach improves the accuracy and transparency of state budget tracking by administrative areas.
2. What Businesses Need to Do to Avoid Clearance Disruptions
The Customs authority confirms that this is purely a technical update with no new tax policies. However, businesses should pay close attention to the following:
- Effective date: From April 1, 2026, the system will operate under the new codes
- Risk of errors: Using old codes may result in rejected declarations or processing errors
- Transition deadline: Declarations registered before April 1 must be completed before June 30, 2026
After the transition period, all old unit codes will be fully deactivated in the system.
For businesses with high declaration volumes or integrated customs software, updating the new unit code list into internal systems is essential to ensure compatibility.
3. Impact on Import-Export Operations
The unified code system brings several long-term benefits:
- Improved accuracy in customs data management
- Faster clearance processes with fewer operational errors
- Enhanced transparency in budget management
- Strong foundation for customs digital transformation
However, in the short term, businesses may face disruptions if system updates are not implemented in time.
4. Implementation Roadmap
Prior to the official rollout, regional customs sub-departments are:
- Reviewing and standardizing location codes
- Communicating updates to the business community
- Preparing systems for synchronized transition
The adjustment process is expected to be completed before March 15, 2026 to ensure readiness.
