China’s revised recommended standard for harmonic drive reducers takes effect in April 2027
GB/T 14118-2026 replaces the 1993 product standard. A separate update to harmonic gear drive terminology takes effect on the same date.
China’s State Administration for Market Regulation and Standardization Administration issued two recommended national standards for harmonic drives on September 28, 2026. Both take effect on April 1, 2027.
GB/T 14118-2026, the product standard for harmonic drive reducers, replaces GB/T 14118-1993 in full. GB/T 12601-2026 covers basic harmonic gear drive terminology. Where purchasing documents cite either standard, listing the number and year helps both parties identify the edition they are using.
Correction — An earlier version incorrectly described the standards as mandatory and gave an audit start date. The official notice classifies both standards as recommended and does not announce an audit schedule.
