Trade Dispute with China and Rare Earth Elements


Background
Since 2018, the United States and China have been engaged
in a trade dispute resulting from U.S. use of Section 301
provisions (which deals with foreign trade barriers). The
dispute has led to several rounds of tariff hikes. The United
States has imposed 25% tariff hikes on $250 billion worth
of products from China while China has hiked tariffs on
$110 billion worth of U.S. products.

On May  10, 2019, President Trump directed the U.S Trade
Representative (USTR) to begin the processes of raising
tariffs on essentially all remaining imports from China,
which it valued at approximately $300 billion. A week
later, the USTR published a list of Chinese products that
could be subject to 25% ad valorem tariffs. The notice
specified that certain products, including rare earth
elements (REEs), would not be included on the list.

On May  20, Chinese President Xi Jinping made a
publicized visit to a REE magnet facility in Jiangxi
province. A May 29 editorial by Xinhua (the Chinese
government's official state-run press agency) warned that
by waging a trade war against China, the United States
risks losing the supply of materials that are vital to
sustaining its technological strength.

The back and forth on REE have increased concerns among
some U.S. policymakers over potential vulnerabilities to the
U.S. economy from China's role as a major supplier of REE
and other critical materials. For additional information, see
CRS  In Focus IF1 1226, Defense Primer: Acquiring
Specialty Metals, Rare Earth Magnets, and Tungsten, by
Heidi M. Peters; and CRS Report R41347, Rare Earth
Elements: The Global Supply Chain, by Marc Humphries.

What are REEs?
REEs  consist of 17 elements (metals) that have unique
characteristics, such as magnetism, luminescence, and
strength. They have a wide range of uses, including in many
high technology industries and defense systems. Contrary to
the name, rare earths are not rare. Rather, they are
relatively abundant in the earth's crust, but are highly
scattered and usually found mixed together in other
deposits. This makes it difficult to find REEs in a
concentration high enough to be mined and separated
economically. The United States was once a major producer
of REEs from the mid-1960s until around the late 1980s
when China became  a major low-cost producer and
exporter of REEs. This, among other factors, caused many
U.S. REE miners and producers to withdraw from the
market.

REE   Dependency on China
According to the U.S. Geological Survey (USGS), in 2018,
China accounted for 71% (and possibly higher due to illegal
mining, production, and smuggling in China) of global REE
production in terms of quantity. Chinese data indicate that
its REE exports totaled 53,518 metric tons, with a value of
$517 million. China's top three REE exports markets by
value were Japan (54% of total), the United States (14%),
and the Netherlands (8%). China also exported $1.7 billion
worth of magnets containing REEs (including $201 million
to the United States), an indicator of the significance of
Chinese downstream industries that utilize REEs.

As indicated in Figure 1, China was the largest source of
U.S. REE imports in terms of quantity at 12,557 metric tons
(or 74% of total). China was also the largest U.S. REE
supplier in terms of dollar value, at $82 million (or 56%) of
the total. (Some U.S. REE imports from non-Chinese
sources may have originated in China.) The consulting firm
Adamas  Intelligence estimates that in 2018 China became
the world's largest REE importer (in terms of quantity),
including $79 million worth of REE imports (largely REE
ores and fluorides).

   Corm     ercial  Industrial   and  MJlitary   Uses
   of REEs
   According to the USGS, the largest U.S. industrial uses of
   REEs in 2018 were for catalysts (at 60% of total); ceramics
   and glass (15%); metals and alloys (10%); and polishing
   (10%) (see Figure 2). Examples of industries that utilize
   REEs in production include advanced electronics (which
   involve magnets, batteries, phosphors, polishing, and metal
   alloys); medical equipment (magnets, batteries, phosphors,
   and polishing); hybrid and conventional vehicles (magnets,
   catalysts, and batteries); energy efficient lighting
   (phosphors); steel (metal alloys); wind turbines (magnets);
   and chemicals (catalysts). REEs have numerous military
