Imposts: A Comprehensive Overview

Whenever goods are traded between countries, there is one event that is expected and often unavoidable: paying customs duties. These fees are collected by governments for the purpose of raising revenue, protecting domestic industries, and regulating import and export activities. Customs duties are known by several names such as tariffs, taxes, levies, and imposts.

In this article, we will delve deeper into the concept of imposts, what they are, who collects them, how they are calculated, and their global significance.

What are Imposts?

An impost is a form of tax levied on imported or exported goods that are crossing a country’s borders. It is a form of indirect tax that is collected upon the clearance of consignments at a port or an airport. It is important to note that customs duties may vary depending on the type of goods being imported or exported, their value, and the time and place of transaction.

Customs duties have existed for centuries and have been an important source of income for governments worldwide. They are generally used to cover the cost of administering the customs and border control services and to protect domestic industries by making imported goods more expensive.

Imposts are an essential tool for regulating trade between countries. They can be used to level the playing field, ensuring that domestic producers do not face unfair competition from cheaper imports. This form of taxation prevents dumping, which is the practice of exporting goods at a price lower than what they are being sold for in the country of origin. It also provides a means of controlling the flow of goods in and out of a country.

Who Collects Imposts?

Customs duties are typically collected by the government of the country of import or export. Customs agencies are responsible for enforcing customs regulations, assessing and collecting customs duties, and preventing smuggling.

In the United States, the Customs and Border Protection (CBP) is the agency responsible for collecting customs duties. In the United Kingdom, HM Revenue and Customs (HMRC) is responsible for collecting customs duties. In China, the General Administration of Customs is responsible for collecting customs duties.

How are Imposts Calculated?

Customs duties are calculated using two methods: ad valorem and specific duties. Ad valorem duties are calculated as a percentage of the value of the goods being imported or exported. Specific duties are calculated based on a fixed sum for each unit of measurement, such as weight or volume.

The World Trade Organization (WTO) encourages its member countries to use ad valorem duties as they are more transparent and less vulnerable to manipulation. The WTO has also been working to promote the use of lower tariffs and to remove non-tariff barriers to trade in order to promote free trade and global economic development.

It is important to note that customs duties can be subject to change based on a variety of factors such as political will, market demand, and global economic trends.

Global Significance of Imposts

Customs duties have a significant impact on global trade and the world economy. A country’s decision to impose a tariff or levy on imported goods can have far-reaching effects on other countries’ economies, global supply chains, and consumers’ wallets. Here are some examples:

1. Global Supply Chains: Imposing customs duties on imported goods can disrupt global supply chains and lead to higher costs for consumers. For example, a tariff on steel imports into the United States would lead to higher costs for American manufacturers that use steel, which could lead to higher prices for consumers.

2. Economic Growth: Customs duties can have a direct impact on a country’s economic growth. Import duties are often implemented to protect domestic industries, but they can also lead to retaliatory measures by other countries. This can result in a trade war, which can reduce global economic growth and negatively impact employment rates.

3. International Relations: Customs duties can also impact international relations between countries. For example, a country that imposes high tariffs on imported goods from another country may cause that country to retaliate with similar tariffs, leading to strained relations between the two nations.

4. Revenue Generation: Customs duties are an important source of revenue for governments around the world. In some countries, customs duties represent a significant portion of the national budget. For example, customs duties in India represent around 8% of the country’s total revenue.

5. Smuggling: Customs duties can also be used to prevent smuggling of illegal goods such as drugs, weapons, and counterfeit products. Customs agencies use a variety of technologies such as x-rays, sniffer dogs, and surveillance cameras to detect smuggled goods.


An impost is another name for a tariff or a customs duty which is imposed upon imports that are being brought into and occasionally out of a nation. An impost is a fee that can be charged by a government in order create a general revenue regarding goods being brought into the nation.

This type of tax was extremely important during a time when trading was the primary way of business throughout the World. Nations would often put an impost or a tax onto goods being brought in, as a way to ensure the legality of the trade, and to secure money for the government.

Impost is used as a way to protect the domestic markets that are found within a nation.

By charging a tax on goods being brought into a nation, the government is regulating what is being brought in, and the frequency of the occurrence. This is helpful for nations who have a rich surplus of goods.

However, a tax on goods that are not produced in the nation is also beneficial, because it creates steady revenue for the nation who requires the goods, and allows for an established business relationship for the nation that has the goods to provide.

Tax that is imposed on goods can often be used to help maintain the ports, travel ways, and military that is used for these types of trading and acquisition endeavors. Impost has been and continues to be an important and ever-changing aspect of business between nations.
