Is US import reliance on China falling faster in non-critical sectors?
Core argument: China's share of US critical-goods imports rose from 6.2% in 2002 to 17.9% in 2017, then fell to 11.1% in 2023, a decline of 6.8 percentage points, based on the Cybersecurity and Infrastructure Agency's sector classification.
Figure 2 partitions aggregate US import dependence from China across critical and non-critical sectors, based on a classification by the Department of Homeland Security's Cybersecurity and Infrastructure Agency. Over this period, we find that China has been an important source of imports of non-critical goods, while a more modest yet non-trivial source of critical goods. Moreover, we find that US-China import dependence in critical sectors increased in tandem with aggregate import dependence—from 6.2% of critical goods imports in 2002 to 17.9% in 2017. However, the systematic decline of total US imports from China has been faster in non-critical goods: The import share from China declined by around 9 percentage points for non-critical goods, while among critical goods it declined by 6.8 percentage points—from 17.9% in 2017 to 11.1% in 2023.
