Understanding what is customs declaration can significantly impact your import-export business success. This critical process ensures compliance with international trade regulations while helping reduce clearance times. When handled properly, it minimizes tax calculation errors and helps businesses avoid potential risks. This guide walks you through the essential steps, highlights common mistakes, and shows how to optimize your customs declaration process to save both time and money.
1, What is customs declaration?
Customs declaration is the process of providing detailed information about imported and exported goods to customs authorities. This information helps authorities control the flow of goods, ensure compliance with legal regulations, and accurately calculate taxes due.
a, Main components of a customs declaration form
A complete customs declaration form should include the following elements:
- Basic information about goods: Name, quantity, weight, unit of measure
- Value of goods: FOB price, CIF, or other trade terms
- HS code (Harmonized System): International goods classification code
- Origin of goods: Country of production or origin of goods
- Information about the importer/exporter: Name, tax code, address
- Information about the means of transport: Sea vessel, aircraft, land transport…
b, Importance of customs declaration
Customs declaration is not just an administrative procedure but also brings many practical benefits for businesses:
Ensuring legal compliance
Accurate customs declaration helps businesses comply with legal regulations on import and export goods management. This helps avoid legal risks and administrative penalties for incorrect or incomplete declarations.
Important note: According to the 2014 Customs Law, penalties for false declarations can be up to 20% of the tax difference amount or higher in cases of repeat offenses.
Determining accurate tax obligations
Through customs declaration, customs authorities have a basis to accurately calculate the types of taxes that businesses must pay:
- Import tax
- Export tax
- Value-added tax
- Special consumption tax (if applicable)
Accurate customs declaration helps businesses avoid overpaying or underpaying taxes, thereby optimizing business costs.
Accelerating clearance time
An accurate customs declaration process helps goods clear customs quickly, minimizing additional costs such as storage fees, yard fees, demurrage… Especially with perishable goods or urgent deliveries, short clearance time is a decisive factor for business efficiency.
Supporting risk management by customs authorities
The customs declaration system supports customs authorities in risk management and goods flow classification. Businesses with a history of accurate declarations and good compliance will often be classified in the green channel, helping reduce inspection time and speed up the clearance process.
2, Detailed customs declaration process
Currently, there are two main customs declaration methods: manual declaration and electronic declaration. However, electronic declaration is gradually replacing the manual method due to its efficiency and speed.
a, Preparing documents and certificates
Before making a customs declaration, businesses need to prepare the following documents:
| Document | Description | Quantity |
|---|---|---|
| Commercial contract | Purchase agreement between parties | 01 copy |
| Commercial Invoice | Details of shipment value | 01 original |
| Packing List | Detailed list of quantity, weight | 01 original |
| Bill of Lading (B/L or AWB) | Transport document | 01 copy |
| Certificate of Origin (C/O) | Confirms origin of goods | 01 original |
| Specialized permits | Applicable to goods under management | 01 original |
Useful tip: Prepare 1-2 additional copies of each document in case supplements are needed during the clearance process.
b, Electronic customs declaration (VNACCS/VCIS)
VNACCS/VCIS (Vietnam Automated Cargo Clearance System/Vietnam Customs Intelligence Information System) is a modern electronic customs declaration system currently applied in Vietnam. The declaration process is as follows:
Step 1: Register account and install software
- Register an account to use the system with the General Department of Customs
- Install electronic customs declaration software (VNACCS/VCIS)
- Prepare digital signature to authenticate declarations
Step 2: Declare information
- Enter complete information into the declaration system
- Attach related electronic documents
- Carefully check information before sending to avoid errors
Step 3: Submit declaration and receive feedback
- Send electronic declaration to the customs system
- The system will automatically classify into channels:
- Green channel: Goods are cleared immediately without inspection
- Yellow channel: Document inspection before clearance
- Red channel: Inspection of both documents and physical goods
Step 4: Pay taxes and fees
- Pay taxes according to notifications from the system
- Can be paid online through affiliated banks
Step 5: Receive clearance notification
- The system will send notification when goods are cleared
- Print the customs declaration that has been cleared for other purposes
Software and support systems
Currently, many software tools have been developed to support businesses in the electronic customs declaration process:
- VNACCS/VCIS: Official software of the General Department of Customs, provided free of charge, integrated with digital signatures and automatically updated with policy changes.
- ERP/CRM software: Modern business management software can automatically integrate data from internal processes to the customs declaration system, saving time and minimizing errors.
- Intermediary software: Solutions such as ECUS, Unitech, Softdream… provide user-friendly declaration interfaces and connection APIs to simplify the declaration process.
c, Manual customs declaration
Although electronic declaration is common, some cases still require manual declaration:

- Submit declaration and documents: Submit directly to the customs sub-department
- Inspection and classification: Customs officers will inspect and classify
- Pay taxes: Pay taxes at designated treasury or bank
- Receive cleared declaration: Receive declaration with clearance confirmation
Post-clearance supplementary declaration
In case errors are discovered after goods have been cleared, businesses are responsible for supplementary declarations:
- Deadline for supplementary declaration: 60 days from the date of declaration registration
- Method of supplementary declaration: Online or submit documents directly
- Handling violations: Depending on the severity of the violation, may be subject to administrative fines or tax collection
3, Common mistakes and how to avoid them
Customs declaration is a complex process, and businesses often make the following mistakes:
a, Incorrect HS code classification
Issue: HS codes determine tax rates and management policies. Incorrect classification can lead to application of wrong tax rates or overlooking specialized management regulations.
Solution:
- Refer to Vietnam’s latest import-export goods catalog
- Use HS code classification consulting services
- Request advance HS code confirmation from customs authorities for new or complex goods
Real example: A business importing “water filtration equipment” declared it as “household water filters” (HS code 8421.21.11) instead of “industrial water filtration equipment” (HS code 8421.21.19), leading to discrepancies in import tax and VAT.
b, Incorrect customs value declaration
Issue: Incorrect declaration of customs value leads to incorrect tax calculation and penalties.
Solution:
- Comply with the 6 methods for determining customs value according to regulations
- Keep complete documentation proving the declared value
- Consult with customs authorities in advance for special cases
Consequences of incorrect declaration:
- Tax collection + late payment interest
- Fines from 10% to 20% of the tax difference amount
- In serious cases, may face criminal liability
c, Lack of specialized inspection permits
Issue: Many businesses forget to apply for specialized inspection permits before importing.
Solution:
- Check the list of goods subject to specialized inspection
- Apply for permits before the shipment arrives at port
- Use consulting services for guidance on the permit application process
| Goods group | Regulatory agency | Permit application time |
|---|---|---|
| Food | Ministry of Health/Ministry of Agriculture and Rural Development | 5-15 days |
| Electronic equipment | Ministry of Information and Communications | 7-10 days |
| Chemicals | Ministry of Industry and Trade | 10-30 days |
| Pharmaceuticals | Ministry of Health | 15-45 days |
d, Not updating with new regulations
Issue: Customs declaration regulations frequently change; failure to stay updated can lead to incorrect process application.
Solution:
- Regularly follow the General Department of Customs website
- Participate in customs seminars and training courses
- Register to receive legal newsletters from specialized consulting units
