According to industry sources, the U.S. Department of Commerce (DoC) has listed China's LED epitaxy chip and chip manufacturer Sanan Optoelectronic Co., Ltd. on the unacknowledged list (UVL) to remind U.S. companies to be cautious.
The U.S. Department of Commerce's Industrial Safety Agency said that UVL foreign companies or organizations are not eligible to receive items subject to export control regulations (EAR) by way of license exceptions. That is to say, American suppliers can no longer sell EAR-specified items to UVL foreign companies or organizations through licensing exceptions, but must obtain new licences.
Sources said that although the inclusion in the Unconfirmed List (UVL) was not a trade ban, foreign companies or UVL organizations had to go through complex procedures to trade with U.S. suppliers, or would hinder subsequent transactions between the two sides.
According to reports, among American suppliers, American Applied Materials Company has stopped supplying Sanan.
Sources said that because Sanan has expanded its product development from LED to semiconductor chips for optical communications such as GaAs, DoC's inclusion of Sanan in the Uncertained List (UVL) may be due to national security concerns.
Subsequently, Sanan said it did not know why it was included in the Unconfirmed List (UVL), but it had organized a task force to process applications deleted from the Unconfirmed List. Sanan said that the suspension of supply by the Applied Materials Company would not have a substantial impact on Sanan's production, as there are other suppliers.
Sources pointed out that Sanan's customers in the United States may transfer orders for LED chips to Crystal Optoelectronics or Lunda Electronics.
