Ad Valorem Duty, Meaning, Type, Examples, Role in Trade

The United States has imposed 100% ad valorem duty on the import of certain patented pharmaceuticals and associated pharmaceutical ingredients.

Ad Valorem Duty Meaning

Ad valorem duty refers to a tax that is imposed as a percentage of the value of a good, service, or property. The term “ad valorem” literally means “according to value.” Unlike specific taxes, which are charged as a fixed amount per unit, Ad valorem duties vary depending on the market value of the item.

For example, if a product worth ₹1,000 is subject to a 10% ad valorem duty, the tax will be ₹100. If the value increases, the tax amount also increases proportionally.

In contrast, under a specific tax, the tax is fixed regardless of value. For instance, if a duty of ₹50 per unit is imposed on a product, both a ₹500 item and a ₹1,000 item will be taxed ₹50 each, showing that the tax does not change with the value of the product.

Types of Ad Valorem Taxes

Ad valorem taxation is widely used in different forms across economies.

• Property tax is a common example, where tax is charged on real estate based on its market value. 
• Sales tax is another form, applied as a percentage of the price of goods and services at the point of purchase. The rate may vary depending on the region and type of product.
• Customs duties, which are highly relevant in international trade, are often ad valorem in nature. Imported goods are taxed based on their value.

Ad Valorem Duty in International Trade

In global trade, Ad valorem duties are widely used as tariff instruments. Governments impose them to regulate imports, protect domestic industries, and generate revenue.

The recent decision by the United States to impose a 100% ad valorem duty on certain patented drugs illustrates how such duties can be used as a tool of trade policy and strategic economic protection. The move was linked to concerns about dependence on foreign pharmaceutical supplies and reflects the use of tariffs for national security considerations.
