- Customs value is the fundamental basis for determining payable import duty and VAT.
- International freight and cargo insurance are standard upward adjustments to the invoice price if not already included.
- Incoterms rules play a decisive role in defining the cost components that constitute dutiable customs value.
- Inaccurate declaration or omission of freight charges can trigger customs valuation rejection and administrative penalties.
Understanding Customs Valuation for Imported Goods
For importers and exporters, calculating payable duty is a critical component of shipment financial planning. However, a common misconception is that duties and taxes are assessed solely on the commercial invoice value. In reality, under prevailing customs valuation regulations, duties are assessed on the dutiable value, also known as the customs value.
The customs value of imported goods is essentially the actual price paid or payable up to the first point of entry. This means any expense incurred in moving cargo from the foreign seller's warehouse to a port or airport in Vietnam is potentially dutiable. Among these costs, international freight (F) and cargo insurance (I) are the two most frequently misunderstood elements.

Why Are Freight and Insurance Dutiable?
The core principle of customs valuation is to capture the full economic value of goods upon arrival at the border of the importing country. A consignment located at a seller's facility in Germany differs in commercial value from the same consignment once safely delivered to Cat Lai Port or Tan Son Nhat Airport. Freight and insurance costs enhance the commercial utility and marketable value of those goods within the Vietnamese market.
Consequently, when purchasing under terms where the commercial invoice excludes freight and insurance, Customs authorities require importers to add these costs to the transaction value to establish the dutiable customs value. This ensures equity in tax liabilities among importers regardless of the commercial trade terms utilized.
The Role of Incoterms in Determining Dutiable Value
Incoterms (International Commercial Terms) not only delineate obligations and risks, but also serve as the legal benchmark for determining whether freight and insurance are already included in the invoice price. Below is the standard classification that VPL routinely advises clients on:
| Incoterms Rule | Freight (F) and Insurance (I) | Customs Declaration Procedure |
|---|---|---|
| EXW, FCA, FOB | Excluded from invoice price. | The importer must add actual F and I costs to the dutiable value. |
| CFR, CPT | Includes freight, excludes insurance. | The importer must add insurance (I) to the dutiable value. |
| CIF, CIP | Includes both freight and insurance. | The dutiable value typically equals the invoice value (absent other adjustments). |
Example: If you import a dangerous goods (DG) shipment from Shanghai to Ho Chi Minh City under FOB terms, the commercial invoice covers only the cargo cost. You must settle ocean freight directly with the carrier/forwarder (such as VPL) and pay insurance to the underwriter (if purchased). Upon customs declaration, you must add these freight and insurance amounts to determine import duties and VAT.
How to Determine Dutiable Freight and Insurance Amounts
Determining these amounts must be supported by objective, quantifiable documentation:
- Freight Charges: Based on the contract of carriage, Bill of Lading (B/L) or Air Waybill (AWB), or freight invoices/notices from the logistics service provider. Note: If cargo is transported free of charge or self-transported, the freight value must still be determined in accordance with statutory valuation methods.
- Insurance Premium: Based on the cargo insurance policy or certificate of insurance. If the importer did not purchase cargo insurance, this component is not added to the dutiable value.
Important Note: Charges directly linked to transporting cargo to the first point of entry—such as origin Terminal Handling Charges (THC) and inland transport in the exporting country (under EXW terms)—must be included in the customs value.
Risks of Inaccurate Customs Valuation
At VPL, we advise clients to maintain complete and accurate declarations. Omitting freight charges or insurance premiums can lead to severe consequences:
- Rejection of Declared Value: Customs authorities possess the right to challenge and reject the declared transaction value if deemed unreasonable or lacking corroborating documentation.
- Tax Assessment: Customs will re-determine the customs value using statutory hierarchical methods and issue an official duty assessment, typically resulting in higher liabilities than projected.
- Administrative Penalties: Importers may face administrative fines ranging from 10% to 20% of the under-declared duty amount, or potential prosecution for tax evasion if fraudulent intent is determined.
- Impact on Customs Routing (Green/Yellow/Red Channel): Repeated value adjustments degrade the enterprise's compliance rating within the customs risk management system, channeling subsequent consignments into physical inspection (Red Channel), causing cargo dwell delays and detention/demurrage expenses.
