Tariff status: a moving target

No U.S. tariff action names Tonga. These are the universal measures — applied to every country without a country-specific arrangement — that set its treatment.

1. 2026-04-06

   Section 232 metals coverage expanded

   In effect

   The April 2026 proclamation strengthening Section 232 actions on aluminum, steel, and copper expanded derivative-product coverage for all countries, keeping the general metals rate at 50%.

2. 2026-02-24

   IEEPA reciprocal tariffs terminated — replaced by 10% Section 122 surcharge

   In effect

   Executive Order 14389 (Ending Certain Tariff Actions) terminated the IEEPA tariff duties — including the EO 14257 reciprocal baseline — effective February 24, 2026. A flat 10% Section 122 temporary import surcharge (Proclamation 11012 of February 20, 2026) replaced them, leaving the universal rate unchanged at 10% on a different statutory basis. Section 122 caps such surcharges at 150 days, so this 10% surcharge is scheduled to lapse on or about July 23, 2026 absent further action (the administration has signaled it could raise the rate toward the 15% statutory maximum).

The first humans arrived in Tonga around 1000 B.C. The islands’ politics were highly centralized under the Tu’i Tonga, or Tongan king, by A.D. 950, and by 1200, the Tu’i Tonga had expanded his influence throughout Polynesia and into Melanesia and Micronesia. The Tongan Empire began to decline in the 1300s, with civil wars, a military defeat to Samoa, and internal political strife. By the mid-1500s, some Tu’i Tongans were ethnic Samoan, and day-to-day administration of Tonga was transferred to a new position occupied by ethnic Tongans. Dutch navigators explored the islands in the 1600s, followed by the British in the 1770s, who named them the Friendly Islands. Between 1799 and 1852 Tonga went through a period of war and disorder. In the 1830s, a low-ranking chief from Ha’apai began to consolidate control over the islands and was crowned King George TUPOU I in 1845, establishing the only still-extant Polynesian monarchy. During TUPOU's reign (1845–93), Tonga became a unified and independent country with a modern constitution (1875), legal code, and administrative structure. In separate treaties, Germany (1876), Great Britain (1879), and the US (1888) recognized Tonga’s independence. His son and successor, King George TUPOU II, agreed to enter a protectorate agreement with the UK in 1900 after rival Tongan chiefs tried to overthrow him. As a protectorate, Tonga never completely lost its indigenous governance, but it did become more isolated and the social hierarchy became more stratified between a group of nobles and a large class of commoners. Today, about one third of parliamentary seats are reserved for nobles. Tonga regained full control of domestic and foreign affairs and became a fully independent nation within the Commonwealth in 1970. A pro-democracy movement gained steam in the early 2000s, led by ‘Akilisi POHIVA, and in 2006, riots broke out in Nuku’alofa to protest the lack of progress on reform. To appease the activists, in 2008, King George TUPOU V announced he was relinquishing most of his powers leading up to parliamentary elections in 2010 and henceforth most of the monarch’s governmental decisions, except those relating to the judiciary, were to be made in consultation with the prime minister. The 2010 Legislative Assembly was called Tonga’s first democratically elected Parliament. King George TUPOU V died in 2012 and was succeeded by his brother Crown Prince Tupouto‘a Lavaka who ruled as George TUPOU VI. In 2015, ‘Akalisi POHIVA became Tonga’s first non-noble prime minister.
