Global Steel Plant Authorization Letter Electronic Wall

China: Digitalization of Supply Chain Driven by Blockchain Technology

China is in a leading position in the electronic field of steel authorization letters, with a typical case being the blockchain electronic quality assurance certificate and electronic signature system of Ouye Cloud Commerce. The system achieves tamper proof, traceable, and online circulation of authorization letters through blockchain technology, with specific features including:
Digitization of the entire process: Steel mills can generate electronic quality assurance certificates online, and traders can split them as needed (such as splitting the quality assurance certificate for 40 tons of steel into 4 copies of 10 tons). Downstream buyers can scan the code to verify the authenticity and circulation history.
Smart Contract Management: The electronic signature "EuSign" is based on the Hyperledger Fabric consortium chain and automatically executes authorization processes through smart contracts to ensure data security and operational transparency.
Cost reduction and efficiency improvement: As of the end of 2023, the system has served over 7300 enterprises, signed over 430000 electronic documents, and achieved a cumulative cost reduction of approximately 6.8 million yuan.

Europe: Import Monitoring and Certification System

Although there is no unified authorization letter electronic wall in Europe, electronic management of some qualifications has been achieved through the EU Steel Import Monitoring System (SIGL) and EN1090 certification:
SIGL system: A non-tariff trade measures platform used by the European Union to monitor steel imports. Companies need to submit import authorization applications online, but mainly for trade quotas rather than production or sales authorizations.
EN1090 certification: Compulsory certification for steel structure products entering the European market. Enterprises need to pass the audit of the notified body and obtain the CE mark. Relevant certification information can be queried through the EU certification database, but it is not directly linked to the authorization letter for public disclosure.
