Customs Clearance is the entire legal procedure required for exported and imported goods to be inspected, verified, and authorized to cross the border by the customs authority. This process includes customs declaration, document submission, tax calculation, and cargo release.

Import-export businesses often struggle to distinguish between declaration types, prepare the correct documentation, or handle inspection channels on the VNACCS/VCIS system. The article below sets out the full definition, required documents, procedure, declaration types, and current legal basis for Customs Clearance in Vietnam.

1. What Is Customs Clearance?

Customs Clearance refers to the customs clearance procedure (in Vietnamese, also called khai báo hải quan or làm thủ tục hải quan), commonly abbreviated in the industry as CC. It is the process in which the customs declarant declares, submits, and presents documentation for the customs authority to inspect, verify, calculate tax, and decide on the release of exported or imported goods.

Customs Clearance: Process & Procedures Explained

Under Clause 21, Article 4 of Customs Law No. 54/2014/QH13, customs procedure refers to the tasks that the customs declarant and customs officer must carry out as required so that goods and means of transport can be cleared or allowed to exit/enter the country. In practice, import-export activities in Vietnam carry out Customs Clearance mainly through electronic means on the VNACCS/VCIS System operated by the General Department of Vietnam Customs.

Real-world example: A shipment of machinery imported from China arriving at Cat Lai Port must complete Customs Clearance before the container can be taken out of the port — including declaration registration, channel classification, document inspection (for yellow/red channel), and payment of import duty and VAT.

2. What Is the Purpose of Customs Clearance?

Customs Clearance ensures that the State can manage exported and imported goods, collect export-import taxes correctly and in full, while preventing smuggling, trade fraud, and the movement of prohibited or restricted goods.

Specifically, the clearance procedure serves four main purposes:

  • State management of customs: controlling the quantity, category, and origin of goods crossing the border.
  • Collecting export-import tax: calculating and collecting import duty, export duty, VAT, and special consumption tax (if applicable).
  • Controlling commodity policy: ensuring goods are not on the prohibited list and do not violate specialized licensing requirements.
  • Trade statistics: providing import-export data to support economic policy-making.

3. When Is Customs Clearance Required?

Businesses must carry out Customs Clearance every time goods cross the Vietnamese border in the form of export, import, temporary import for re-export, temporary export for re-import, or transit.

Regarding deadlines, an import customs declaration must be registered before the goods arrive at the checkpoint or within 30 days from the date the goods arrive; an export declaration is registered after the goods have been gathered at the location notified by the declarant. Late submission or incorrect timing may result in administrative penalties under customs regulations.

4. Who Carries Out Customs Clearance?

Customs Clearance is carried out by the customs declarant, which includes three main groups: the cargo owner (importer/exporter), a customs broker licensed with a code by the General Department of Vietnam Customs, and a party legally authorized by the cargo owner, such as a forwarder company with customs declaration authority.

In practice, most small and medium-sized enterprises choose to authorize a logistics provider or professional customs broker to handle Customs Clearance, due to the need for constant updates on HS codes, tax policy, and channel-classification procedures on the VNACCS/VCIS system.

3. What Documents Are Required for Customs Clearance?

The basic Customs Clearance dossier includes the electronic customs declaration together with commercial and transport documents proving the sale transaction and the actual shipment. The number of documents may increase depending on whether the goods fall under specialized management.

The standard customs dossier under Circular 38/2015/TT-BTC (amended by Circular 39/2018/TT-BTC and updated by Circular 121/2025/TT-BTC) includes:

  1. Electronic customs declaration (declared on the VNACCS/VCIS System)
  2. Commercial Invoice
  3. Packing List
  4. Bill of Lading or Airway Bill
  5. Sales Contract
  6. Certificate of Origin (C/O), if the business wants to enjoy preferential tax rates under an FTA
  7. Specialized license (if the goods fall under the management of a relevant ministry or sector)
  8. Quarantine or quality inspection certificate (if the goods are subject to specialized inspection)

Note: A missing Packing List or a weight discrepancy against the Bill of Lading is a common reason a shipment gets pushed into the yellow or red channel, extending Customs Clearance time by an extra 1-3 working days.

4. Customs Declaration Procedure in Vietnam

The customs declaration procedure in Vietnam consists of 5 main steps: preparing documents, filing the electronic declaration on VNACCS, channel classification (green/yellow/red), carrying out the corresponding inspection, and paying tax before the goods are released.

Step 1: Prepare and Check Documents

The customs declarant gathers all commercial documents and determines the HS Code, customs value, and the appropriate export-import type code before declaring.

Step 2: File the Electronic Customs Declaration

Declaration is carried out on the VNACCS/VCIS System. Once filed, the system automatically issues a declaration number and returns the channel-classification result.

Step 3: Channel Classification

The automated risk-management system classifies the declaration into one of three channels: green channel (exempt from document and physical inspection), yellow channel (detailed document inspection), and red channel (physical inspection of the goods).

Step 4: Document Inspection or Physical Inspection of Goods

For the yellow channel, the customs officer cross-checks the paper documents against the declared data. For the red channel, the goods are physically inspected in whole or in part at the port, warehouse, or yard.

Step 5: Pay Tax and Clear the Goods

Once the documents or goods are confirmed compliant, the business pays the applicable export-import tax, the system confirms clearance, and the goods are permitted to leave the customs-supervised area.

5. Types of Declarations Used in Customs Clearance

On the VNACCS System, Customs Clearance uses several different declaration types depending on the direction of the goods and the nature of the transaction. Below are the common declaration types listed in the exact order they are applied in practice.

  1. Export goods declaration (type-code group E, e.g. E11, E21): used for Vietnamese goods exported abroad, including commercial export, export for manufacturing/export, and processing export.
  2. Import goods declaration (type-code group A, e.g. A11, A12, A41): used for goods imported into Vietnam, including commercial/consumer import, processing import, and investment import.
  3. Independent transport declaration (OLA): declared for goods transported from the entry checkpoint to an inspection site or bonded warehouse, not tied to an official export/import declaration.
  4. Combined transport declaration (KLA): declared jointly with an export or import declaration when goods need to be transferred between checkpoints.
  5. Amended/supplementary declaration (AMA/AMC): used when adjusting information on a still-valid original declaration, such as correcting the value, quantity, or HS code.
  6. Paper customs declaration (form HQ/2015-NK, HQ/2015-XK): applied in special cases such as a VNACCS system malfunction or goods not eligible for electronic declaration under regulations.

6. How Is Customs Declaration Different from Customs Clearance?

Customs declaration is the step where the declarant enters shipment information into the electronic declaration, while clearance is the final outcome once the customs authority confirms the goods are eligible to circulate. Declaration is an action; clearance is the legal status after that action is completed.

CriteriaCustoms DeclarationCustoms Clearance
ConceptThe act of entering data, declaring shipment informationThe outcome confirming the goods are permitted to circulate
TimingOccurs first, as soon as the declaration existsOccurs after the documents/goods have been inspected

7. Common Mistakes Businesses Make with Customs Clearance

The three most common types of mistakes when carrying out Customs Clearance are incorrect HS Code declaration, missing specialized documents, and incorrect declaration of customs value — all of which can delay clearance or trigger back-tax assessments.

Common MistakeConsequenceHow to Fix It
Incorrect HS Code declarationBack-tax assessment, possible administrative penaltiesCheck the Export-Import Tariff Schedule, request an advance classification ruling from the General Department of Vietnam Customs
Missing specialized licenseDeclaration is held, clearance cannot proceedCheck the list of specially-managed goods before declaring
Incorrect customs value declarationSuspected of fraud, pushed to red channel, back-tax collectionCross-check the declared value against the commercial invoice and original contract
Quantity/weight mismatch between documentsExtends physical inspection timeReview the Packing List and Bill of Lading before filing the declaration
Late declaration filingAdministrative penalties under customs regulationsTrack vessel/flight schedules, file the declaration within the required deadline

Real-world example: An electronics importer misdeclared the HS code by confusing a similar product group, resulting in a reassessed import duty and nearly a week of extra processing to appeal the classification at the local Customs Sub-Department.

8. Current Legal Regulations on Customs Declaration

Customs declaration in Vietnam is currently governed directly by Customs Law No. 54/2014/QH13, Decree 08/2015/ND-CP, and the Ministry of Finance’s guiding Circulars, most recently Circular 121/2025/TT-BTC, effective from February 1, 2026.

  • Customs Law No. 54/2014/QH13 — sets the overall framework for customs procedures, inspection, and supervision.
  • Decree 08/2015/ND-CP — provides detailed provisions and measures implementing the Customs Law on procedures, inspection, supervision, and control.
  • Circular 38/2015/TT-BTC (amended by Circular 39/2018/TT-BTC) — regulates customs procedures, inspection, supervision, export-import tax, and tax administration.
  • Circular 121/2025/TT-BTC (issued December 18, 2025, effective from February 1, 2026) — amends and supplements Circular 38/2015 and Circular 39/2018, updating the electronic customs declaration procedure in line with Law No. 90/2025/QH15 and Decree 167/2025/ND-CP.

Businesses should track the entry into force of Circular 121/2025/TT-BTC from February 1, 2026, as it changes certain regulations on customs dossiers for transit goods and on amended/supplementary declaration procedures compared with the previous rules.

9. Frequently Asked Questions (FAQ)

Is Customs Clearance mandatory for every export-import shipment?
Yes. Every shipment exported from or imported into Vietnam across the border must go through Customs Clearance under the Customs Law, except for certain non-commercial shipments subject to separate rules on tax-exemption thresholds and simplified declaration.

How long does Customs Clearance take to complete?
For the green channel, clearance typically takes just a few hours within the same working day. The yellow channel takes about 1 day for document inspection, while the red channel can take 2-3 days due to physical inspection of the goods at the port or warehouse.

Is a business required to handle Customs Clearance itself?
No. A business can either declare the shipment itself or authorize a customs broker or forwarder company with declaration authority to handle the entire Customs Clearance process.

How long is a customs declaration valid?
A customs declaration remains valid for 15 days from its registration date. If clearance is not completed within this period, the declaration expires and the business must file a new one.

When does an amended/supplementary customs declaration apply?
It applies when an error is found in the value, quantity, HS code, or other information on the original declaration, and can be carried out before or after clearance depending on the nature of the correction and the applicable deadline.

Must goods classified into the red channel undergo a 100% physical inspection?
Not necessarily. The customs authority may inspect the entire shipment or only a certain percentage of it, depending on the risk level assessed by the Risk Management System.

Are Customs Clearance and customs procedure the same thing?
Essentially, yes. “Customs Clearance” is the English term, while “thủ tục hải quan” or “khai báo hải quan” is the Vietnamese way of referring to the same goods clearance process.

What should businesses keep in mind to speed up Customs Clearance?
Businesses should prepare complete documentation, declare the correct HS code from the start, carefully cross-check figures across all documents, and work with an experienced logistics provider that knows how to handle yellow- and red-channel cases to shorten clearance time.
