"Japan’s trade ministry said on July 1st that it will restrict the export of some tech materials to South Korea. The list of restricted supplies includes polyimides used in smartphones, flexible organic LED displays, etching gas, and resist used to make semiconductors. That means Japanese suppliers who wish to sell those materials to South Korean tech companies such as Samsung, LG, and SK Hynix each will need to submit a contract for approval. In this case, the import period will be extended by about 90 days. This took effect on July 4th, but there is a one-month grace period. It seems that the Japanese government intends to inconvenience the tech exports to South Korea by lengthening the import period or complicating the process rather than imposing a ban on import. This could be the political intention of the Japanese government ahead of the elections this month, so the situation is likely to change sharply after voting ends in late July. Thus, it is too early to talk about the price increase of semiconductors, displays, or even the impact on final products' prices as well." – Sujeong Lim
