On April 24, 2026, the "2026 China Six-Axis Force Sensor Industry Development White Paper" was officially released. The document points out that in 2025, the market size of China’s six-axis force sensors exceeded 300 million yuan, with the main growth drivers coming from two major scenarios: humanoid robot joint force control and intelligent automotive assembly. At present, an initial trend has emerged in which overseas humanoid robot manufacturers are centrally procuring domestically produced high-precision six-axis force sensors, creating substantive impacts on force/torque sensor export enterprises, functional safety certification service providers, and precision manufacturing supply chains. Relevant industries need to promptly identify changes in business interface requirements.

Event Overview

The "2026 China Six-Axis Force Sensor Industry Development White Paper" was released on April 24, 2026. The white paper confirms that: in 2025, China’s six-axis force sensor market exceeded 300 million yuan; growth mainly came from demand for humanoid robot joint force control and intelligent automotive assembly applications; from 2026–2027, overseas humanoid robot manufacturers such as Tesla Optimus Tier-2 suppliers and Agility Robotics channel partners will centrally procure domestically produced six-axis force sensors that comply with ISO 10218-2 dynamic torque accuracy requirements (±0.1% F.S.); exports must simultaneously meet ASME BPE or IEC 61508 functional safety certification requirements.

Which Market Segments Will Be Affected

Direct Trading Enterprises

Because the white paper explicitly points to overseas procurement entities such as Tesla Optimus Tier-2 suppliers and Agility Robotics channel partners, trading enterprises directly engaged in six-axis force sensor exports will face a shift in order structure—from sporadic sample deliveries to a model combining bulk deliveries + bundled certification. The impact is reflected in: greater weight of functional safety clauses in export contracts, compressed delivery cycles, and increased frequency of compliance reviews for technical documentation.

Processing and Manufacturing Enterprises

The white paper proposes ISO 10218-2 dynamic torque accuracy (±0.1% F.S.) as a key procurement threshold, and this indicator is higher than the routine control level of most current domestic production lines. The impact is reflected in: existing production lines needing to verify dynamic performance calibration capabilities; some enterprises may need to introduce third-party dynamic calibration services; and greater pressure on process stability and batch consistency management.

Supply Chain Service Enterprises

Functional safety certification (ASME BPE or IEC 61508) has become a precondition for export, but certification cycles are long and adaptation costs are high. The impact is reflected in: phased growth in demand for supporting services such as certification consulting, testing laboratories, and safety software integration; small and medium-sized manufacturing enterprises will rely more heavily on third-party certification service platforms to complete the closed loop of export qualification.

Channel Distribution Enterprises

The white paper mentions "channel partners" as one of Agility Robotics’ procurement paths, indicating that overseas end customers are distributing technical specifications and procurement intentions through localized channels. The impact is reflected in: regional distributors with technical understanding capabilities seeing increased value in functions such as selection support, document translation, and local certification coordination; purely logistics-based channel roles are facing pressure to upgrade their services.

What Key Points Should Relevant Enterprises or Practitioners Focus On, and How Should They Respond at Present

Focus on the Market’s Dual Response Rhythm to Dynamic Accuracy and Functional Safety

What deserves more attention at present is whether Tesla Optimus Tier-2 suppliers and Agility Robotics channel partners have already launched bidding or sample validation in Q2 2026; and whether there are differences in trust preferences for ASME BPE and IEC 61508 across different regional markets (for example, North America tends toward ASME BPE, while Europe tends toward IEC 61508), which will directly affect the choice of certification path and the priority of resource allocation.

Distinguish the Timing Gap Between the White Paper’s Statements and Actual Procurement Implementation

The white paper indicates that 2026–2027 will be the window period for concentrated procurement, but it does not disclose the scale of the first batch of orders, detailed acceptance standards, or the possibility of certification exemptions. Analysis suggests that 2026 will be more characterized by technical alignment and qualification pre-review, while large-scale shipments may be postponed until the first half of 2027. Enterprises should avoid directly equating policy signals with immediate revenue growth.

Start Internal Verification Preparation for ISO 10218-2 Dynamic Torque Accuracy in Advance

It is recommended that manufacturing enterprises benchmark against the dynamic loading test methods specified in Appendix C of ISO 10218-2 (including operating conditions such as step response and sine sweep), and identify capability gaps in existing calibration equipment; they may cooperate with metrology institutes to conduct pre-assessments, so as to avoid exposing missing dynamic performance data during the customer audit stage.

Establish a Coordinated Working Mechanism for Functional Safety Certification

ASME BPE or IEC 61508 certification involves multiple dimensions such as hardware architecture, software safety mechanisms, and fault diagnosis logic, and cannot be covered by isolated corrective actions. It is more appropriate to understand it as requiring the formation of a cross-functional team composed of R&D, quality, and production departments, with the simultaneous launch of safety lifecycle documentation (such as safety plans, FMEA, and safety manuals), while reserving a certification cycle buffer of at least 6 months.

Editorial Viewpoint / Industry Observation

Observably, this white paper is not a mandatory technical roadmap document, but rather a trend assessment tool formed on the basis of industrial chain research. At present, it is more like a structural signal—marking that domestically produced six-axis force sensors are moving from the "usable" stage into the "integrated" stage, meaning downstream system manufacturers are beginning to incorporate them into the design phase of complete-machine safety architectures. Analysis shows that whether export volumes truly scale up still depends on three variables: the mass production ramp-up speed of overseas humanoid robot OEMs, the compliance rate of domestically produced sensors in achieving mass-production consistency for dynamic accuracy, and the approval rate of functional safety certification bodies in auditing domestic production lines. The industry needs to continue observing supply chain announcements from leading robot manufacturers and public cases released by certification bodies starting from Q3 2026.

Conclusion: this white paper reveals that the high-precision force sensing segment is moving from the background to the foreground of the robotics industry chain. Its significance does not lie in immediate order conversion, but in forcing domestically produced sensors to accelerate the closing of gaps in three areas: dynamic performance verification capability, functional safety engineering capability, and international standards response capability. At present, it is more appropriate to understand it as the launch of a capability benchmarking process oriented toward system integration needs, rather than a definitive conclusion that an export inflection point has already arrived.
