China became a net industrial-robot exporter for the first time in 2025, with H1 cobot exports reaching $746 million, up roughly 60% year-over-year, and integrator-direct pricing now runs 20–40% below Western distributor channels [S3].
Verified Chinese cobot brands build 6-axis arms in the 3–20 kg payload band with reach from 625 mm to 1,700 mm, repeatability between ±0.02 mm and ±0.1 mm, and IP54 protection as the baseline; Elfin-Ex explosion-proof variants extend the envelope into Zone 1/21 dust-and-gas cells [S2][S4][S5]. Lead times on OEM-branded orders run 4–10 weeks, and most factories will customize the housing, teach pendant, and controller branding but will not license the core motion-control firmware [S1].
Functional safety is the gate, not the CE sticker
ISO 10218-1 and ISO 10218-2 govern the industrial robot itself, and ISO/TS 15066:2016 is the governing technical specification for collaborative operation, listing four collaborative modes: safety-rated monitored stop, hand guiding, speed and separation monitoring, and power and force limiting; Annex A of that document defines the quasi-static and transient force limits that finger, palm, and back-of-hand contacts must respect [S1][S5].
Buyers in the EU routinely reject a cobot that cannot demonstrate traceability to ISO/TS 15066 Annex A even when the arm itself carries a valid CE mark under ISO 10218-1/-2, because the force-limiting thresholds are what govern the actual human-robot contact event, not the machinery directive alone [S1][S5]. A TÜV-issued safety report covering the four collaborative modes is materially stronger evidence than a self-declared DoC, and most reputable factories (AUBO, JAKA, Elite, DOBOT, FAIRINO) will furnish test reports on request without pushback [S1][S3]. For North American sites, UL listing is not legally required for industrial robots but many insurers and large OEM end-users mandate it; confirm the file number and the NRTL that issued it before signing a PO [S3].
Payload, reach, repeatability, and zone class: the four numeric axes
Cobot selection reduces to four spec-sheet axes: payload (typically 3, 5, 8, 12, 16, and 20+ kg), reach (600–1,700 mm for 6-axis arms), repeatability (±0.02 to ±0.05 mm for precision cells, ±0.1 mm acceptable for material handling), and IP rating (IP54 standard, IP65+ for washdown or coolant-exposed cells) [S5]. The fifth axis, area classification, divides a standard arm from an Elfin-Ex explosion-proof model specified for Zone 1 (gas) and Zone 21 (dust) environments [S5].
Spec the payload with at least a 20% margin over the heaviest part plus end-effector mass; a 4 kg part on a 2 kg gripper needs a 7 kg-rated arm minimum, not a 5 kg model run at its limit [S2]. For a more detailed payload-versus-reach tradeoff in adjacent automation, the linear guide selection logic tracks the same over-spec-by-margin principle because deflection and fatigue are paid for later, not at quote time. CNAS-accredited third-party inspection at the factory before container loading is the standard mitigation for buyers who cannot visit in person; budget 3–5 business days for the inspection window and require the inspector to witness a repeatability test on each shipped unit [S3].
Joint torque sensing and the $15k threshold
Chinese cobots priced below approximately $15,000 typically omit joint torque sensors and rely on current-based collision detection, which detects a crash only after motor current spikes, not from a direct force measurement at the joint [S6]. Joint torque sensing (JTS) provides direct collision-force feedback and is the dominant implementation behind the collaborative force-limiting claims in ISO/TS 15066 Annex A, so sub-$15k arms need speed-and-separation monitoring or a hard-guarded cell to maintain compliance, which often negates the headline price advantage once safety scanners and light curtains are added [S6].
Buyers who need true power-and-force-limiting collaboration should treat the presence of joint torque sensors on the published bill-of-materials as a hard requirement, and should request the supplier's PFL threshold table (in Newtons) for the finger, palm, and back-of-hand body regions per Annex A, not a generic "ISO/TS 15066 compliant" marketing claim [S5][S6]. If the cell uses a vision-built-in cobot such as the Techman TKM-1000, the integration hours drop because fixture localization runs through the vendor's native camera stack, but the buyer is then locked into that vendor's vision pipeline for spares, firmware updates, and field service [S5].
Comparing the verified Chinese cobot brands
Direct comparison of the four most-sourced Chinese cobot lines on the dimensions that drive RFQ decisions: [S5]
AUBO (Beijing), JAKA (Shanghai), and Elite Robot (Suzhou) sit in the established tier, all publishing ISO 10218-1/-2 and ISO/TS 15066 evidence with TÜV or equivalent third-party reports and offering OEM branding of the housing, pendant, and controller from MOQ in the single digits to tens of units [S1][S3]. DOBOT (Shenzhen), UFACTORY (Shenzhen), and FAIRINO (Shanghai) overlap on payload and reach but skew toward distributor channels (Top3DShop, Blue Sky Robotics, plus US entities DOBOT US and UFACTORY US) where the 10–25% markup buys English-language support, local warranty, and faster shipping [S3]. Huayan Robotics (Guangdong) differentiates with the Elfin-Ex explosion-proof variant for Zone 1/21 cells and 17 named application cells covering welding, CNC, palletizing, and grinding, while Henan Boy Machinery (Luoyang) exports 40 collaborative-robot SKUs to Europe and Southeast Asia/Mideast with MOQ 1 pc and average response time ≤9.4 h [S5]. SZGH (Guangdong) markets the BCi series with PLd/CAT3-rated collision detection, level-10 sensor safety per joint, and 0–50 °C ambient rating across eight models from 3 kg / 625 mm to 20 kg / 1,650 mm, with optional Profinet and SDK support in C++, Lua, Python, and ROS [S2].
For a deeper cobot procurement playbook tied to these payload and safety tradeoffs, see the Cobot Procurement Strategy: Payload, ISO Safety, and Sourcing Map reference. Plants stepping up from a single cobot to a mobile manipulator should review the AGV robot envelope constraints, because mobile bases change the speed-and-separation monitoring math versus a fixed arm.
Shipping, payment, and the distributor shortcut
Western distributors (Top3DShop, Blue Sky Robotics, plus manufacturer-owned US entities DOBOT US and UFACTORY US) sell Chinese cobots at 10–25% above factory-direct pricing but include English-language support, local warranty, and simplified customs handling; the math favors this channel at 1–3 units where one service event can erase the price delta [S3]. Direct factory sourcing pays off at 5+ units, when establishing a reseller relationship, or when the buyer needs firmware or branding customization the distributor will not touch [S1][S3].
For buyers also moving adjacent capital equipment such as case packers, the Case Packing Machine Selection for Chemical Shipping: 2026 Spec Path reference applies the same factory-direct-versus-distributor math with the same payment red-flag list.
Limits of Chinese cobots: where the build breaks down
Cobots are not specified for heavy welding of thick steel, high-speed press tending, foundry cells with abrasive debris, or any application where the throughput model requires end-effector speeds above the ISO/TS 15066 Annex A PFL thresholds; plants running 24/7 lights-out automotive body-in-white should stay on traditional fenced industrial robots because the cycle-time math does not close under collaborative limits [S5].
Sub-$15,000 arms without joint torque sensing cannot deliver true power-and-force-limiting collaboration and will need supplementary speed-and-separation monitoring hardware to remain compliant in cells where human contact is expected [S6]. For higher-payload or longer-reach cells, the crossed-roller guide and articulated robot references cover the structural-design tradeoffs that determine whether a 16 kg or 20 kg cobot will hold its repeatability spec after a year of two-shift operation. Track these signals going forward: TÜV certificate numbers and Annex A PFL tables on every revised datasheet, the publication status of any update to ISO/TS 15066, and whether the factory's joint torque sensor BOM is field-replaceable or potted.
