China Gallium Exports Collapse in April as Restrictions Hit Japan Supply

Gallium

China gallium exports collapsed in April as export restrictions sharply reduced shipments to Japan and buying from other key markets slowed after earlier purchases. Customs data showed China exported only 3kg of gallium during the month, all of it wrought material shipped to Malaysia.

China gallium exports were dramatically lower than April 2025, when shipments totalled 4,777kg. That earlier volume included 4,627kg of wrought gallium and 150kg of unwrought material.

China gallium exports remain highly sensitive to licensing controls because the metal is a strategic input for compound semiconductors, radio-frequency electronics, power devices and advanced manufacturing. The April data show how policy restrictions can quickly override normal trade patterns in a small but critical materials market.

The sharp monthly fall also highlights the fragility of gallium supply for downstream users. Even when year-to-date exports remain higher, licensing shifts can leave individual buyers exposed to sudden supply gaps.

Japan Restrictions Reshape Gallium Trade Flows

Japan has traditionally been one of China’s most important gallium export destinations. China exported 42t of gallium to Japan in 2025 before bilateral relations worsened and export controls tightened.

China has prohibited exports of dual-use items for Japanese military use and introduced tighter controls on exports to 40 Japanese companies since January. The measures followed comments by Japan’s leadership on Taiwan that deepened political tensions between the two countries.

These restrictions are expected to continue because bilateral relations show no clear sign of easing. That creates a direct supply-chain issue for Japanese semiconductor, electronics and advanced materials users.

Gallium’s industrial importance is larger than its physical volume. It is used in materials such as gallium nitride and gallium arsenide, which support high-frequency, high-efficiency and high-performance electronic applications.

Japan’s exposure therefore matters for more than one metal trade route. It affects supply security for sectors tied to semiconductors, defence electronics, optoelectronics and advanced manufacturing.

The April collapse also shows how export controls work in practice. They do not need to stop all global shipments to disrupt specific customers. Targeted licensing limits can redirect trade flows and force buyers to rely on inventories, alternative suppliers or delayed procurement.

German Buying Masks Underlying Weakness in Year-to-Date Exports

The January-April export picture looks stronger than April alone. China exported 16,353kg of gallium in the first four months of the year, up 14% from 14,294kg in the same period of 2025.

That increase was mainly driven by German buying earlier in the year. Germany received 16t from China in January-March, but buyers there did not renew purchases in April.

China shipped 22.3t of gallium to Germany in 2025, mostly in the second half, after a major Chinese supplier obtained export permission. This shows how gallium flows now depend heavily on licence availability and timing.

The contrast between strong early German purchases and almost no April exports is important. It suggests that year-to-date data can hide short-term supply stress when licensing-driven shipments are concentrated in a few windows.

For buyers, the key issue is no longer only price. It is whether export licences can be obtained, how much volume is approved and whether shipments can be repeated consistently.

For western semiconductor supply chains, gallium remains a strategic vulnerability. China still has strong influence over supply availability, and small changes in export permissions can have outsized effects on downstream procurement.

The April data therefore reinforce a broader critical minerals lesson. Thin markets such as gallium can become highly unstable when trade policy, diplomatic tensions and dual-use controls intersect.

The Metalnomist Commentary

Gallium is proving that strategic materials risk often appears first in licensing volumes, not headline prices. Japan’s exposure shows why semiconductor supply chains must treat gallium security as a policy risk as much as a procurement issue.
