China is advancing efforts to establish a home-grown barcode technology within the global semiconductor industry by promoting a miniaturized version of its Han Xin code for use on microelectronic components. The State Administration for Market Regulation (SAMR) announced on Monday that the “Micro Han Xin” code has officially entered the international standardization process, aiming to provide a compact identification system suitable for labeling semiconductors and other tiny electronic parts.

Originally developed in 2007, the Han Xin code was introduced as a potential alternative to QR codes but did not gain significant international traction, partly due to the widespread adoption of Japanese-originated formats in consumer applications. The new Micro Han Xin iteration is designed specifically for high-density marking on small-scale components such as sensors, microprocessors, controllers, and memory units involved in semiconductor fabrication, packaging, and testing workflows.

Beijing’s push to secure a role for the Micro Han Xin code reflects a broader strategic goal to insert Chinese standards into critical industrial supply chains, where foreign technologies currently dominate. The semiconductor sector in China relies heavily on established systems, particularly the Data Matrix code developed in the United States nearly 40 years ago, which remains the global benchmark for tracking silicon wafers and electronic components. SAMR highlighted that the Micro Han Xin code offers comparable, if not superior, data density and damage resistance, capable of encoding dozens to over 100 characters in an area small enough to be nearly invisible to the unaided eye.

China plans to integrate the Micro Han Xin code into a forthcoming revision of the ISO/IEC 20830 standard, which governs the broader Han Xin symbology. This update process began in late May and is expected to take approximately two years. Earlier this year, representatives from China’s Article Numbering Centre presented the Micro Han Xin code at an international automatic identification standards meeting, prompting a working group to begin the formal standardization process.

Despite this progress, experts note that gaining formal international standard status does not guarantee widespread adoption. The semiconductor industry already utilizes well-established identification systems with extensive global infrastructure. Previous assessments, including a 2021 report by the global standards body GS1, found that while Han Xin exhibits strong coding efficiency leading to smaller symbols compared to QR and Data Matrix codes, its use outside China remains limited and global scanner support is minimal.

With the microchip manufacturing sector as a narrower but technically demanding target market, Shanghai is focusing on the Micro Han Xin code’s technical advantages rather than mass consumer adoption. Beijing appears to be betting that its home-grown technology’s performance in high-precision applications could carve out a foothold amid established global standards in semiconductor marking and traceability.
