Since the early months of 2018, the United States and China have been locked in a complex and evolving trade conflict, defined by escalating tariffs and strategic industrial policy. Understanding the us tariffs on china timeline is essential for grasping the global economic shifts that followed, from supply chain disruptions to changes in consumer pricing. This conflict, often framed as a battle over technology and trade imbalances, did not emerge overnight but followed a distinct chronological path of announcements, negotiations, and retaliatory measures.
Phase One: Pre-Tension and Initial Investigations
Long before the first tariffs were implemented, the groundwork for the conflict was laid through existing trade imbalances and geopolitical friction. The United States maintained significant trade deficits with China, and concerns regarding intellectual property theft and forced technology transfers were persistent grievances. During the 2016 election cycle and the subsequent early months of the Trump administration, these issues moved to the forefront of policy discussions. The investigation into Chinese technology practices, particularly under Section 301 of the Trade Act of 1974, was initiated in August 2017, signaling a more aggressive stance long before physical tariffs were imposed.
Phase Two: The First Wave of Tariffs (2018)
March 2018: Steel and Aluminum
The timeline officially commenced in early 2018 with measures targeting broader industrial inputs rather than specific Chinese goods. In March 2018, President Trump imposed sweeping tariffs of 25% on steel imports and 10% on aluminum imports, citing national security concerns. While not exclusively aimed at China—Canada and the European Union were also affected—these duties marked the beginning of a protectionist turn in US trade policy that would soon be directed specifically at Beijing.
July and September 2018: Targeted Lists
Later in 2018, the focus shifted to specific Chinese products. On July 6, 2018, the US implemented 25% tariffs on approximately $34 billion worth of Chinese goods, covering industries such as aerospace, information technology, and robotics. This move was met with immediate retaliation from China, which imposed equivalent tariffs on US agricultural products, notably targeting soybeans. Just weeks later, on August 23, the US raised tariffs to 25% on an additional $16 billion of Chinese imports, prompting China to respond in kind with another $16 billion list.
Phase Three: Escalation and Negotiation Lulls (2019)
Throughout 2019, the conflict oscillated between moments of tentative diplomacy and sharp escalations. In May 2019, the Trump administration announced it would increase tariffs on $200 billion worth of Chinese imports from 10% to 25%, citing China’s failure to fulfill promises made during trade talks. In response, China immediately raised tariffs on $60 billion of US goods. The political landscape shifted again in August when the US designated China as a currency manipulator following a sharp devaluation of the yuan, although this designation was largely symbolic and later reversed.
October 2019: Truce and Rollback
A brief reprieve occurred in October 2019 when officials announced a "phase one" deal. As part of this agreement, the US canceled plans to impose new tariffs on the remaining $300 billion of Chinese goods that were previously exempt. This rollback provided a temporary lull in the trade war, stabilizing markets just months before the global pandemic disrupted all economic forecasts.
