Import Customs Duties Guide


Considering total shipment costs? Don’t forget import customs duties. Every import incurs these fees, and understanding their calculation can ensure a smooth, affordable shipment. Dive into our comprehensive guide on import duties, their types, functioning, influencing factors, and calculation methods.

Import Duties, what are they?

Import duties are taxes imposed on imported goods by a country’s customs authorities. They are collected for regulatory purposes and to protect domestic industries.

When you bring goods into a country, whether by air, sea, or land, you’ll likely have to pay these duties. Additionally, you’ll need to provide the appropriate customs clearance documents. This applies whether you’re an individual, a business, or a corporation. Consequently, it’s crucial to factor these costs into your shipping estimates and product pricing.

Different Types of Import Customs Duties, what are they?

Import duties can take various forms, some of which may apply to specific shipments, while others may not. The most frequent types of import customs duties you might encounter during your shipment include:

Basic Customs Duty

The basic customs duty is a standard fee applied to all imports. It can be calculated either as a fixed rate or on an ad valorem basis. Generally, the value of the goods determines the cost of international import duties.


Stepping up to protect local industries, the anti-dumping duty kicks in when goods are imported at lower than market prices. It’s like a safety net, bridging the price gap and stopping the sale of unfairly cheap imports.


Enter the Countervailing duties (CVD). These are the duties that come into play when we’re dealing with subsidized imports. Their job? To level the playing field and keep domestic products competitive against lower-priced foreign goodies. How is CVD calculated? It’s all about the subsidies the foreign government is offering.


When imports are flooding in large quantities, threatening local industry, that’s when the safeguard duty steps in. This duty is the guard dog of the local economy, keeping watch and offering protection when needed.

What Impacts Customs Duties?

The threshold for import duty imposed on your shipment can vary based on three key factors that influence customs duties:

  • Customs duty rates of the importing country – Every country has its own customs duty rules, and the rates can vary widely.
  • The commercial value of the goods – Customs duties are often calculated based on the customs or commercial value of the goods.
  • Origin country – Some countries face more stringent import duties and restrictions than others, depending on trade agreements that can affect duty and tariff rates.

Estimating Import Customs Duties: A Simple Guide

Customs authorities determine import customs duties in several ways. The most common approach is the transaction value method, which calculates import duties based on the value of the goods or the total amount paid by the buyer to the seller, including other expenses such as:

  • Commissions
  • License fees
  • Resale proceeds
  • Processing or assembly costs
  • Preparation and material costs
  • Land and maritime transport costs
  • Insurance

The formula to calculate customs duties is the import country’s rate multiplied by the total customs value of the goods.

To help with customs duties estimations, there are customs duty calculators available. Shippers can easily search and input the commodity code of their goods, and the calculator will generate the duty rate.


Customs duties can significantly influence the cost of your shipment. Therefore, it’s crucial to calculate the potential customs duties for your merchandise. This involves summing up the customs value of your goods, checking for trade agreements between the export and import countries, and staying informed about import customs duties and their workings.
