Pre-testing and rectification in our in-house RF chamber and EMC lab; formal reports from officially designated labs, with every milestone visible.
Each certificate is a market-access gate. We determine which one your product needs, how to get it, and how to get it fast.
Telecom terminals, IT and audio/video equipment — listed products cannot leave the factory or be sold without certification.
The market-access certificate for all radio transmitters: Bluetooth, Wi-Fi, cellular, satellite, intercom and more.
The access credential for cellular terminals, satellite mobile terminals, routers and gateways connecting to public networks.
Each line details product scope, core compliance items, common pitfalls and reference timelines — focused on the three mandatory certifications (CCC, SRRC type approval, Network Access License), plus BeiDou special programs and battery safety testing. Click a line for the full plan.

Certificate numbers can be verified on official portals; we proactively report every milestone, so you can ask where the project stands anytime.

Telecom Equipment Network Access LicenseNetwork Access License sampleEvery certificate we deliver can be found on the issuing body's official portal by its number. Verifying the certificate first is the very first thing we advise every client to do.
Grouped by product line so you can find yourself in the list — we've probably already hit the pitfalls of your product category once.
Client names shown grouped by product line; actual scope, models and progress are per mutual agreement. Unpublished product information is not disclosed.
Many clients first come just asking “which certificate do I need?” As we talk, it turns out what they really want is “how do I get the product to market smoothly, and stay out of trouble afterwards.” So we turned our capabilities beyond filing into products: one team, walking the whole line with you.
We first determine precisely what your product needs, using official catalogs and radio regulations — no contract talk before a conclusion.
Covering China's three mandatory market-access regimes — our in-house lab pre-tests first, officially designated labs issue certificates after.
Getting the certificate isn't the end. Changes, surveillance, renewals — every step anticipated and handled for you.
There are many agencies. The difference: whose lab catches the problems, who tracks the milestones, and who owns the non-conformities.
EMC, RF and electrical-safety pre-tests in-house: fix on the spot, re-test right away — no waiting for third-party slots.
CCC + SRRC + Network Access assessed together, filed in parallel, submitted at staggered times — total timeline clearly shorter than using three separate vendors.
If the product isn't listed or needs no certificate, we say so. We don't force filings to win deals, and we don't let you pay for unneeded certificates.
Official fees, testing fees and service fees itemized in the contract; quoted ranges confirmed by written assessment — no hidden charges.
Submission, rectification, review, issuance — every milestone proactively synced. Ask anytime where the project stands; there's a record.
Annual surveillance, critical-part changes, expiry renewals — reminded and handled in advance, so compliance never lapses after certification.
From the first call to the certificate in hand — what each step involves and who does it, all explained before we start.
Compare official catalogs and radio regulations to determine which certificates, which path, timeline and cost range — written conclusion in 1–3 business days.
The three cost parts itemized in the contract; certification units and submission plan set; milestone schedule shared with both sides.
Document checklist verified item by item; sample self-check; scheduled submission to designated labs.
Pre-tests run first; non-conformity rectification closed-loop; factory inspection pre-checked and accompanied.
Certificate verified on official portals at delivery, marking instructions provided; ongoing surveillance and renewal reminders.
The MIIT “Radio Transmission Equipment Administration Provisions” effective July 1, 2023, requires that radio transmission equipment produced or imported for sale or use in China must obtain type approval before sale, and sales filing; low-power short-range devices follow catalog management. For Bluetooth, Wi-Fi, cellular, satellite or intercom makers: no approval, no sales; sell, then file; platform spot-checks and market regulation will look.
Every case states the product, the bottleneck, the delivery time and the outcome. Company and personal details are anonymized.
Labs, RF test equipment, offices and certification guides — seeing is believing; check the environment before we talk business.
