Customs Valuation: Methods and Import Compliance

Posted on Mar 31, 2026 in Accounting and Finance

Understanding Customs Value

The customs value is the economic value assigned to imported goods at the border. It determines the taxable base for tariffs and Value Added Tax (VAT).

TAXABLE BASE × TAX RATE = TARIFF DEBT

Key Importance

  • Origin Determination: Essential for accurate tariff rates.
  • Accessory Costs: All importation costs must be accounted for.
  • Valuation: Determines how goods are assessed upon arrival.

GATT Principles

The GATT is an international agreement ensuring fair and equal goods valuation.

The 6 Methods of Customs Valuation

When the primary transaction value cannot be used, customs authorities apply one of the following methods:

  1. Transaction Value: The price actually paid or payable for goods sold for export. This is the main method.
  2. Identical Goods: Based on goods equal in physical characteristics, quality, and prestige, produced in the same country.
  3. Similar Goods: Based on goods with similar composition and characteristics that are commercially interchangeable.
  4. Deductive Value Method: Based on the unit price of the largest quantity sold in the importing country to an unrelated buyer, minus specific deductions (commissions, transport, taxes, processing costs).
  5. Constructed Value Method: Calculated as Cost of Production + Profits + Overhead. This is the most difficult to apply.
  6. Last Resort Method: Applied when no other method works; based on “reasonable criteria” and GATT principles.

INCOTERMS and Valuation

Incoterms define how costs are allocated for customs valuation:

  • CIF (Cost, Insurance, Freight): Includes transport and insurance to the border.
  • CIP (Carriage and Insurance Paid To): Similar to CIF, applicable to any transport mode.
  • FOB (Free On Board): Sometimes used as an alternative valuation base.
  • DAP (Delivered at Place): Relevant for identifying included/excluded costs.
  • FAS (Free Alongside Ship): Seller fulfills delivery at the port; risks transfer to the buyer.

The DV1 Form Obligations

Importers must submit the DV1 form alongside the SAD to declare customs value.

Requirements

  • Accuracy and completeness of all listed elements.
  • Authenticity of all supporting documents.
  • Provision of supplementary information requested by customs.

Note: The DV1 is not required for non-commercial imports, goods under €20,000, or when no duties are payable.
