In the intervening period, as China tightened control of domestic output of rare earths – a broad group of 17 elements used in everything from electric vehicles to military hardware – the United States all but surrendered to China’s dominance of the sector.
With China now accounting for 70% of global production, and only one US mine in operation, American industries outside of defence have “no immediate avenues” to break their reliance on China for supply of rare earth elements, according to Citigroup Inc.
It’s why Washington is now facing a new front in its burgeoning trade war with the world’s second-biggest economy, after Beijing signaled its intent to restrict exports of the critical materials.
A possible blacklisting of US companies, or a ban on exports of rare earth metals to the United States, may have have a material financial effect on technology companies that source significant revenue from China, or use rare earth minerals, according to a Fitch Ratings research note.
Here’s a look at the country’s reserves, export regime, dominant players and illegal activities.
> Six dominant producers
China consolidated its mining and separation companies into six licensed groups in 2016. Beijing granted the groups annual production quotas to better manage its strategic mineral resources and ensure the sustainability of the industry.
They were granted mining quotas totaling 120,000 tonnes of rare earths oxide in 2018 compared with 105,000 tons in 2017.
The country plans to cap domestic mining output below 140,000 tonnes by 2020 to preserve resources and will cut smelting and separation capacity by a third from 2015 levels to 200,000 tons, according to the industry’s five-year plan issued in 2016. It’s part of a drive to more than double the sector’s profit margin to 12%.
The following are the six major producers with 2018 quotas, according to the Ministry of Information and Technology.
> Where are the mines?
Baiyun Obo in northern China’s Inner Mongolia, run by China Northern Rare Earth, is the world’s largest mine. It holds 83% of the country’s total reserves, mainly light elements. Mines in Shandong province have 8%, Sichuan has 3% and the rest of the reserves are in southern provinces, mainly in medium-to-heavy forms, according to 2017 data on the China Rare Earth Industry Association website.
> Exports, imports
China has a surplus in light rare earths, which dominate its exports, but needs to import medium-to-heavy types to meet a domestic shortfall, according to SMM Information & Technology Co.
On exports, the government doesn’t have any control on quantity or qualification as companies are only required to present sales contracts to receive licenses.
The country’s outbound shipments of rare earths rose 3.6% to about 53,000 tonnes in 2018, according to Chinese customs data. Exports have been rising every year since 2013. Exports of rare earths and its products, including permanent magnets, rose 5.4% to 95,586 tonnes last year, with 18,852 tonnes, or 20%, to the United States. It relies on China for 80% of its purchases of rare earths.
China’s imports doubled to around 70,000 tonnes last year, making it a major importer for the first time, according to the country’s industry group.
> Illegal mining
While there’s no official data, the country is dogged by illegal exploration and production. A government crackdown has seen illicit production volumes fall significantly from almost being equal to sanctioned output of around 100,000 tonnes of oxide in the middle of the decade, according to Wu Xiaofeng, an analyst with SMM, without giving a specific estimate.
China was estimated to have produced 180,000 tonnes last year, compared with an official quota of 120,000 tonnes, according to a US Geological Survey report that cited Chinese government data.
> Consumption areas Permanent magnet materials account for 44% of China’s consumption, with polishing making up 10%, oil and petrochemicals 9% and the rest used in metallurgical machinery, glasses, catalysts and lighting, according to SMM.
> Looming domestic shortfall
A growing need for permanent magnets in new-energy vehicles is driving demand growth, increasing China’s dependence on imports as domestic production is capped.
Earlier this year, the government issued a first round quota for mined output of 60,000 tonnes, down from 73,500 tonnes a year earlier and compared with 2018’s full-year limit of 120,000 tonnes.
The market will be waiting eagerly for the next round of production quotas, which are due to be released later this month. This year’s first-round quota was relatively low given China’s total demand is expected to rise to 180,000 tons and companies may have to source supplies from overseas, Chen Zhanheng, vice secretary general at the rare earth association, said in March.
