A pre-launch certification checklist for smart locks (Bluetooth/Wi-Fi/fingerprint): the wireless module must have SRRC type approval, CCC catalog placement needs prior determination, and lock-body safety should be self-checked against GB 21556. We explain how the three sets of requirements divide up, how to merge multiple models into one unit, and what extra work the door-viewer camera version requires.
Robot vacuum certification checklist: whole-device SRRC approval for Wi-Fi + Bluetooth, CCC placement under household appliance standards, compliance assessment of the LiDAR (dToF/LDS), plus requirements for the charging dock and lithium battery. We identify which step most often drags the timeline and how to handle Wi-Fi module rectification.
Practical TipsSmart plug/switch certification checklist: CCC safety (mandatory) and SRRC wireless approval running in parallel. For low-priced, high-volume categories, the real fear is being delisted from e-commerce because certification wasn't complete. Four frequent pitfalls: missed accessories, series coverage across models, Zigbee versions, and certification budgets on low-cost products.
Practical TipsNetwork camera/video doorbell certification checklist: beyond whole-device Wi-Fi SRRC approval and CCC catalog determination, imaging-data compliance and cloud service descriptions are becoming new sticking points in listing reviews. We explain wireless configuration tiers, how to word cloud storage descriptions, and the certification differences between overseas and China versions.

We explain how to handle power bank CCC, the filing relationship between cells and finished products, and how to plan time and budget.
Practical TipsAI glasses/AR glasses certification checklist: on top of the Bluetooth earbud checklist (SRRC + accessory CCC), three blocks are added — camera imaging compliance, optical safety of face-adjacent displays, and human exposure assessment for worn scenarios. We explain how the glasses form factor affects RF testing and how to divide units across versions (optical, camera, audio).
Practical TipsService robot (delivery/reception/cleaning) certification checklist across five tracks: Wi-Fi + 4G connectivity, LiDAR, voice interaction, high-capacity batteries and charging dock requirements. We explain how commercial robots differ from consumer ones, the network access requirements for carrier connectivity, and how on-site integration affects submitted samples.
Practical TipsThe full Network Access License chain for phones (including 5G terminals): TAC range application, network access test items, review and issuance, and carrier onboarding.

Practical TipsThe certification path for 5G/4G CPE and MiFi: beyond running the Network Access License, SRRC approval and CCC in parallel, carrier onboarding is the hurdle that actually decides whether you get into the channel. We explain how CPE certification differs from phones, the test impact of antenna gain, and how to handle models with external antennas.
Certification WikiHow 4G/5G cellular modules relate to whole-device certification: a module can obtain its own approval and network access, but the device still has to file — which items can reference module data, which must be retested on the device, and how work splits between module maker and device maker. One relationship table sets out the boundary between referencing and retesting.

Practical TipsIntercom certification splits into two paths: conventional analogue/digital radios (radio transmitting equipment, with SRRC approval at the core) and public-network trunking radios (cellular-connected, classed as telecom terminals, requiring a Network Access License). We explain the criteria for each path, frequency use, SIM/platform requirements for public-network radios, and how to handle export models.
Practical TipsCertification checklist for RTK receivers and modules: GNSS positioning is receive-only and needs no approval; what actually has to be filed is the 4G link, the Bluetooth/Wi-Fi link to the data controller, and BeiDou-only specific testing. We explain how filings split across the RTK product line and the difference between base stations and rovers.
Practical TipsApproval essentials for millimetre-wave radar (traffic/security/automotive/sensing): test requirements follow the band and the application, and antenna arrays with beam scanning make the test scope more complex than conventional RF equipment. We explain band selection, sample form, test positioning and common failure items.

One “change × action” table sets out which changes require re-approval, which go through change filing (priced by band) and which only need to be documented.
Practical TipsMaintaining a CCC certificate over its 5-year validity: how to prepare for the annual surveillance audit, how to file product changes, and how to schedule renewal at expiry. We explain the three post-certification timelines, the most frequent non-conformities in surveillance audits, and the risk of letting a certificate gather dust.

Practical TipsHow Network Access License fees are calculated: service price = testing fee + agency fee (10% of the testing fee); the testing fee varies with the air-interface combination, whether the device is smart, and whether SAR is included. Cellular terminals are also charged for TAC / IMEI ranges. Includes a budgeting method and the negotiation floor.
Practical TipsThe six-step CCC compulsory certification process: catalog comparison, application acceptance, type testing, factory inspection, certificate delivery and post-certification surveillance. The deliverables, duration range and frequent sticking points for each step, plus how the 2–6 month total is allocated.
