The biggest challenge for importers is not sourcing products, but complying with strict export controls. In 2026, Chinese authorities have rolled out a stricter full-life-cycle traceability system for hazardous chemicals, bringing fundamental changes to cross-border trade.
Dual-Use Export License
Potassium chlorate is listed as a dual-use item due to its high chemical reactivity. Legitimate exports require suppliers to hold a special license issued by the Ministry of Commerce of China (MOFCOM). Meanwhile, importers are required to provide a valid End User Certificate (EUC) as part of the regulatory documentation.
QR Code Digital Traceability
Every batch of potassium chlorate exported from China must be attached with a unique digital QR code, which records key information such as production date, purity level and safety data. Products without this traceable code are regarded as unauthorized and will be rejected by Chinese customs during pre-shipment inspection (PSI).
