Tarrifs

In this article, Annie YEUNG discusses the historical development of tariffs and the evolution of tariffs over economic landscapes overtime.

Brief explanation of history of global tariffs

In the 19th century, tariffs were the main source of government revenue in aim for protectionism. Tariffs were widely used to protect domestic industries that were in their beginning stages. Many countries such as the United States and Europe has imposed high tariffs in order to ensure the development of their industrializing economies. For example, the U.S. implemented tariffs, such as the Tariff of Abominations in 1828 to protect its manufacturing industry. During the post World War II era, the General Agreement on Tariffs and Trade was established in 1947. In response to the post war devastation, countries lowered their tariffs in order to promote economic growth. Reciprocal lower tariffs were also implemented amongst countries and trading partners. Starting in near the beginning of the 21st center, the launch of the World Trade Organization in 1995 marked a significant evolution in global trade, where governance of trade tariffs were established through the launch of the WTO. The WTO emphasized on the trading of goods and introduced a governance structure for development considerations, granting special support for developing and less developed countries. The WTO also introduced an institutional structure for the dispute settlement procedures on global trading. Today, tariff reductions have continued due to negotiations and regional trade agreements, which deepened the harmonization of the global markets, facilitating increased global trade volumes. However, during the last decade, there has been an introduction of resurgence of tariffs amongst increased instability in the current geopolitical grounds. Tariffs has served as a political tool. For example, the U.S.- China trade war has seen tariffs as an economic tool under rising geopolitical tensions where billions of dollars of goods subject to tariffs. As two of biggest economies globally, this trade war has disrupted global supply chains. This has posed challenges as other countries have also employed tariffs for protectionism goals.

The Protectionism Approach

The United States has been maintaining high tariffs to nurture for its developing domestic industries during the 19th centuries. The United States has seen an increase in the average tariff rate over a century of time. During the beginning of the 19th century, the U.S.Average Tariff Rate was 35%, whereas by 1913, the U.S. Average Tariff Rate has increased to 40%. This historical evolution could be attributed to the need for domestic protection; early industrialization period during the early 19th century required protection, whereas in the beginning of the 20th century, tariffs needed to support the growing industry. European countries such as Germany and France also utilized tariffs to protect industrial growth during this period of time. However, developing countries struggled developing tariffs as threir internal markets were still in developing stages. However, beginning from the early 1900s, there has been a further rise in nationalism. Some tariffs rates exceeded 60%, and as a result, global trade decreased by 66% between 1929 to 1934. This was also during the period of the Great Depression, in which these tariff hikes and set-back in economy was a result of reduced international trade.

Trade Liberalization

After the establishment of the General Agreement on Tariffs and Trade in 1947 to reduce tariffs, there have been successful negotiation amongst nations to cut average tariffs worldwide in order to reduce protectionism and open up markets to global trading activity. This is seen from the data presented from the World Bank World Development Indicators, which there has been a gradual deduction in average global tariff rate from 15% to 6% from from the year 1950 to 2000. Since the beginning of tariff reductions and the start of post-war rehabilitation and rebuilding of the economy in 1950, continued multilateral negotiations has resulted in a historic low of tariffs in the year 2000. As a result, trade volumes increased and there was a global economic growth.

Complex Socio-economical landscapes

Despite the decreasing of average global tariff rate, trade policies in the 21st century, especially in the recent years, has grown to become more complex. For example, there has been targeted tariffs and trade conflicts, leading. To increased uncertainty in global trading markets. For example, U.S. has increased its tariffs from the year 2017 to 2020, with the average U.S. Tariff Rate of 1.6% in 2017 plummeting to 3.1% in the year 2020. This could have been attributed to the increased policies on tariffs on steel, aluminum, and the trade wars with China, resulting to much higher tariff rates compared to the beginning of the 2000s. For example, targeted tariffs has become a strategic target tariff, a tool with political goals. For example, the steel and aluminum tariff was to protective domestic industries, which the Trump administrated imposed a 25% tariff on steel and 10% on aluminum in March 2018. These tariffs were to uphold national security to maintain the U.S. domestic metals industry. However, this tariff led to price increases and resulted in retaliation of tariff policies from its trading partners.

< p> Increased tariffs from one country often results in retaliatory tariffs from its trading partners. Not just China, but there were also other countries that have responded to U.S.’s tariff hikes, including Canada, the European Union, and India. As a result, the increase in tariff has resulted in increased uncertainty to the global trade environment, affecting stock markets, companies, local businesses etc. Hence, the tariff can cast direct effects to each producer and consumer domestically, as investors raise concern over costs, and supply chains are rendered volatile, slowing businesses.

A Case Study: The European Union’s tariff on Chinese Electric Vehicles

In the year 2024, the European Union imposed tariffs of 38.1% on Chinese imported electrical vehicles. This is an example of the shifting grounds of global trading market environments. Today, tariffs have increased globally, and this tariff is an example that has marked a shift in the European Union trade policy and has great implications for the global automotive industry as well as the international trading landscapes. For example, the EU has imposed different tariffs targeting on specific different companies. The SAIC Motor has an 38.1% tariff, whereas Geely experiences a 20% tariff, while BYD has a 17.4% tariff for all goods imported into the European Union from China. These tariffs were imposed by the EU due to the low prices that Chinese manufacturers deliver to the European market, which may potentially undermine local producers through competition. In response to the tariff, China has filed a complaint with the World Trade Organization to contend for EU’s actions, appealing that the EU may have constituted to protectionism under fair competition. The tariff casts a large impact on the European EV market, which European consumers are facing higher prices. Market share also shifts, as the tariffs has changed the competitive landscape; Chinese manufactured EVs are facing higher costs, which may benefit domestic European manufacturers. Hence, the EU’s recent tariffs on Chinese manufactured electric vehicles marks today’s international trade policies amongst the historical evolution of global trade and tariffs, and has sparked debate and challenges.

In this article, Annie YEUNG (ESSEC Business School, Global Bachelor in Business Administration (GBBA) – Exchange Student, 2025) explains about understanding how tariffs are crucial for consumers, suppliers, and policymakers.

Introduction: What are tariffs?

Tariffs is a tax that is placed on imported and exported goods, essentially, a duty on goods when they cross international borders. Tariffs are taxes that is imposed by a government, and they are often utilized by governments to protect domestic industries, raise government revenue, and influent foreign policy. Tariffs are always impacting global economies on a large scale, as the effect they bring are always to large bodies of consumers and suppliers internationally, especially if the tariffs are imposed by a country with large export or import volumes. Trade tariffs make a direct effect by making imported goods more expensive, and they can often shift increased consumptions towards domestically produced goods. Tariffs take effect by rendering international imported goods more expensive, which consumers would, due to effect of demand, increase their quantity demanded towards domestic goods. Hence, tariffs take effect in protecting domestically produced goods, and may achieve political goals. However, as prices are increased, consumers often need to pay a higher price, which this may lead to inefficiencies and deadweight loss; this may lead to trade disputes.

Different types of tariffs

Ad Valorem Tariffs

An Ad Valorem Tariff is a tariff that is added onto the price of the imported good as a percentage. For example, an ad valorem tariff may be a 10 percent tax that is added onto the price of each good imported. Hence, an ad valorem tariff means that the more expensive a good is, the more tariff is added on. This may mean that higher valued imported goods are rendered much more expensive and takes greater effect as a result from the tariff.

Specific tariffs

Specific tariffs are tariffs that charges a fixed fee on the quantity or physical unit of the imported good. Hence, special tariffs are imposed on goods that are regardless of their price, and it would be a fixed fee that is imposed per physical unit of the imported good. For example, a specific tariff could be a $1 imposed on per kilogram of wheat that is imported wheat into the country. The economic impact are easier to administer and do not adjust with the market price of the good.

Compound tariffs

A compound tariff is a combination of both ad valorem and specific tariffs. Compound tariffs may include both an ad valorem tariff and a specific tariff combined to be imposed on an imported good.

Sliding Scale tariffs

Sliding scale tariffs are a variable tariff rate that are adjusted based on global commodity prices, domestic supply levels, inflation volatility etc. The tariff is dependent on when world prices of the good increases or rises. When world prices decrease, the sliding scale tariff increases, and when world prices increase, the tariff decreases. Hence, this tariff takes an economic effect by helping to maintain a minimum domestic price of a good, and helping to balance price stabilization. Hence, sliding scale tariffs may help stabilize domestic goods’ prices, and smooths the supply and demand for domestic goods, protecting domestic producers and reducing market volatility in face of global economic changes.

Protective tariffs

Protective tariffs take effect by protecting domestic industries from foreign competition. The goal of imposing a protective tariff is to encourage consumers to purchase more from domestic by raising the price of internationally imported goods. As a result, when demand for domestic goods increase as a result from protective tariffs, more domestic jobs can be created, and growth of local industries are secured, which exemplifies the protection for these domestic sectors.

Revenue tariffs

Revenue tariffs are tariffs to raise government revenue instead of protecting domestic producers. The purpose of imposing revenue tariffs is to generate an income for the government, especially when the country’s economic system heavily depends on imported goods and has a high volume of imported goods. However, revenue tariffs may be a great burden for domestic consumers as they bear the higher prices of goods, and may affect trade flows and consumption choices within the population, as consumers are the major price payers under a revenue tariff.

Economic Effects of Tariffs

Tariffs can create multidimensional impacts on the global economy both in short term and long term, and consumers, producers, governments, as well as international relations may all be affected. Hence, tariffs are a very important factor in influencing the international landscape and may cast a great effect on global economic markets.

The effect of tariffs on consumers

Tariffs firstly directly impacts consumers. When a government imposes tariffs, suppliers importing a good internationally will need to pay an extra cost to the government. As a result, this will raise prices of goods, reducing the purchasing power of consumers. Furthermore, as pries increase for imported goods, consumers may find more limited choices in the market, and this may lead to consumer dissatisfaction.

The effect of tariffs on domestic producers

Tariffs are generally casting a more beneficial effect for domestic producers as they often result in increased output and employment to domestic industries. With more demand turned to domestic producers, they may result in higher sales and revenue outputs, boosting the economic return for domestic producers. While tariffs may provide protection to domestic industries as they gain a price advantage over foreign producers, there may be reduced competition. Furthermore, domestic producers may also be harmed through tariffs if they rely on foreign inputs. For example, when domestic producers rely on imported raw materials, their input cost increases, and this may result in less profit earned.

The effect on governments and the international landscapes

Trade tariffs may generate positive impacts to governments, as trade tariffs may act as a channel for revenue generation. Governments also utilize trade tariffs for political goals, and may cast a strategic effect on trade negotiations and affect the economic diplomacy. Simultaneously, trade tariffs may manipulate trade flows, and cause dissatisfaction, as rising consumer prices may lead to domestic unrest and trade wars. When one country imposes a tariff, this may often provoke retaliation from other countries, leading to a spiral of protective tariffs, that rises global prices and slows global economies. Hence, tariffs can lead to trade wars and lead to geopolitical instability.
