A practical guide for manufacturers planning market entry into China
Introduction
If you are bringing a wireless or radio-frequency product to China, two acronyms will shape your market-access timeline and budget: SRRC and NAL. Both are mandatory approvals, administered under their own regulatory scopes, and each exists to confirm that a device meets Chinese law and technical standards before it can be sold, marketed, or operated in the country. The two schemes are frequently confused, partly because they share an authority, overlap in their testing logic, and are often pursued back-to-back for the same product.
Knowing precisely which approval your product needs and whether it needs one, the other, or both, is critical in the early product compliance stages. China is a Tier 1 market, and like other Tier 1 markets (the United States, Canada, the EU, etc.), its requirements reward advance planning and penalize compliance teams that treat compliance as a final gate. Our strongest recommendation is to begin thinking about China compliance in the earliest product design phases, when frequency bands, module choices, and firmware architecture can still be adjusted at low cost.
In this article we walk through both the SRRC and NAL approval processes, then compare and contrast them directly: where they overlap, where they diverge, where you can save time and money by sequencing them intelligently, and the key challenges manufacturers should expect when entering the China market.
SRRC Approval (State Radio Regulatory Commission Certification)
SRRC is China’s mandatory type approval for any device that intentionally transmits radio frequencies. Many of the most common wireless technologies like Bluetooth, Wi-Fi, and cellular fall squarely within its scope. In recent years China has selectively deregulated certain categories, most notably micro-power short-range devices (often referred to as low-power devices, or LPDs), to lower barriers and make the market more accessible to foreign manufacturers. Key points of the SRRC radio type approval process include:
- Certificates are issued by the State Radio Regulatory Commission (SRRC).
- SRRC is the national radio spectrum and frequency-allocation authority of the People’s Republic of China, operating under the Ministry of Industry and Information Technology (MIIT).
- SRRC confirms that a device’s radio transmission characteristics (frequency, power, modulation) comply with Chinese spectrum regulations.
- Many wireless products must obtain an SRRC Radio Type Approval before being sold or used in China, however there are specific exemptions.
- Micro-power short-range / low-power devices (LPDs) are exempt from the SRRC type approval requirement (examples include certain NFC and RFID devices), provided they fall within the official catalogue and stay within the prescribed technical limits under MIIT Announcement No. 52 [2019].
How the SRRC Certification Procedure Works
The SRRC testing and certification process is comparable in complexity to other Tier 1 markets. First, an account must be established with SRRC. Local, in-country testing is then required before the certification submission. The essentials:
- The applicant may be an overseas manufacturer or a local company with a registered SRRC account that acts as the legal representative. (This is a meaningful contrast with NAL, see below.)
- Documentation requirements to establish an account:
-
- Business license in Simplified Chinese with company stamp and signature. If the license is in another language, a Simplified Chinese version is also required, and both must carry the company stamp and signature.
- The identification (ID) number of the legal representative.
- Documentation requirements to test and apply for a certificate (English unless specifically mentioned):
-
- Application form in Simplified Chinese
- Type Approval Commitment Letter for Radio Transmitting Equipment (Simplified Chinese)
- Commitment Letter for Type Approval Testing Services for Radio Transmitting Equipment (Simplified Chinese)
- Key component list
- Model Approval Sample Information Sheet
- OEM agreement (Simplified Chinese, or Simplified Chinese and English)
- Technical datasheet
- User manual in Simplified Chinese
- Product label template: product information, applicant information, and CMIIT ID number
- Photos: internal and external
- Authorization letter (if needed)
- Test instruction / SOP
- Testing: performed at an accredited laboratory within China. RF testing measures frequency stability, output power, occupied bandwidth, spurious emissions, and other RF specifications.
- Samples: product-dependent, with a minimum of 5 conducted samples per model.
- Each model receives a unique CMIIT ID. Family certification is not permitted.
- Validity is typically 5 years and is renewable. (Note: some industry summaries cite shorter renewal terms; under the current regulation both new and renewed certificates are generally issued with 5-year validity, while certain categories such as UWB may be shorter. Confirm the term for your specific device category at the time of filing.)
- Renewals should be submitted before the current certificate expires (commonly up to 3 months in advance); otherwise, full retesting and recertification may be required.
- Typical lead time is around 10 weeks, covering both testing and certification.
- Customs can present additional friction. We always advise that the in-China recipient of the sample units review the shipping airway bill and label before the shipment departs.
Why it matters: China strictly controls radio spectrum. SRRC ensures your device will not interfere with other systems or violate national frequency rules. SRRC testing and certification are mandatory before a product can be shipped to, marketed in, or operated in China.
NAL Approval (Network Access License)
NAL is China’s mandatory license for telecommunications terminal equipment such as phones, cellular tablets, and data devices that connect to public networks. Its scope differs from SRRC, and NAL is frequently required in addition to SRRC, depending on the device. Critical points of the NAL process:
- Certificates are issued by the Ministry of Industry and Information Technology (MIIT).
- MIIT is a cabinet-level executive department of the State Council, responsible for the postal service, internet, wireless, broadcasting, communications, electronic and information-goods production, the software industry, and promotion of the national knowledge economy.
- MIIT ensures that devices connecting to China’s public telecom networks (2G/3G/4G/5G, fixed-line, etc.) meet safety, interoperability, and quality standards.
- NAL builds on the SRRC certificate. A granted SRRC approval is a prerequisite, since SRRC test results form part of the basis for NAL.
- NAL is required for mobile phones, cellular tablets, data cards, and other telecom terminals.
- Without NAL, a device cannot legally connect to Chinese telecom networks.
How the NAL Certification Procedure Works
The NAL process is also complex, and structurally like SRRC. A key distinction appears at the very first step: the account and the certificate holder that acts as the legal representative must be a local Chinese company. Foreign manufacturers without a Chinese subsidiary must appoint a local representative to file and hold the license on their behalf. Local, in-country testing is then required before submission.
- The applicant must be the local company, with a valid account.
- Documentation required to establish an account:
-
- Business license of the applicant
- The identification (ID) number of the legal representative
- Documentation requirements to test and apply for a certificate (English unless specifically mentioned):
-
- Application form in Simplified Chinese
- Business license of manufacturer
- Business license of factory
- Business license of applicant
- Applicant introduction
- Manufacturer introduction
- OEM factory introduction
- ISO certification of the manufacturer
- ISO certification of the factory (must include the correct scope)
- Org chart of manufacturer
- Org chart of OEM factory
- Org chart of applicant
- Photos: internal and external
- OEM agreement (Simplified Chinese, or Simplified Chinese and English)
- User manual in Simplified Chinese
- Technical datasheet
- Label template
- Testing: at an accredited lab within China. Tests include electrical safety, EMC, network compatibility, and environmental reliability (broader than SRRC’s RF-focused testing).
- Samples: a minimum of 7 conducted samples. SRRC samples can sometimes be reused for NAL testing, but to expedite both processes, separate samples are recommended.
- Each model receives its own unique NAL code. Family approval is not permitted.
- Validity is typically 3 years, for both new and renewal applications.
- A factory inspection may form part of the NAL process for certain product categories — unlike SRRC, which has no factory audit.
- Renewals must be submitted before the current certificate expires; otherwise retesting and recertification may be required. Renewals are often a lighter, paperwork-driven transaction.
Why it matters: NAL ensures your device works correctly with China Mobile, China Unicom, China Telecom, and other operators. NAL testing and certification are mandatory before in-scope products can be shipped to, marketed in, or operated in China.
Comparing and Contrasting SRRC and NAL
At a high level, SRRC governs the airwaves and whether your device transmits legally within China’s spectrum rules, while NAL governs the network and whether your device may attach to and operate correctly on public telecom infrastructure. A product can need only SRRC (a Wi-Fi speaker), or both SRRC and NAL (a 5G phone). The table below summarizes the key distinctions.
Where They Are Similar
- Same ultimate regulator. Both ultimately sit under MIIT, so the two schemes speak a shared administrative language and share the CMIIT ecosystem.
- Mandatory, in-country testing. Neither approval accepts foreign test data in lieu of local testing. Both require samples to be tested at China-accredited laboratories.
- Simplified Chinese documentation for certain documents.
- Per-model approval, no family grouping. Each model earns its own identifier (CMIIT ID or NAL code); you cannot roll a product family under a single certificate.
- Renewal discipline. Both must be renewed before expiry to avoid lapse and potential full retesting.
- Gatekeepers to market. Neither is optional for in-scope products: no approval means no legal shipment, sale, or operation in China.
Where They Differ
- Regulatory question answered. SRRC asks “does it transmit legally?”; NAL asks “may it join the public network?”
- Who can hold the certificate. This is the single most consequential difference for foreign manufacturers. SRRC can be held by an overseas entity; NAL must be held by a local Chinese company or appointed representative.
- Sequencing. SRRC is independent; NAL is dependent and you cannot obtain NAL without SRRC in hand first.
- Breadth of testing. SRRC is RF-centric. NAL reaches further into safety, EMC, network interoperability, and reliability.
- Factory oversight. SRRC involves market surveillance but no factory audit; NAL can involve a factory inspection for some categories.
- Validity term. SRRC certificates commonly run 5 years; NAL 3 years, meaning your renewal calendars for the two will drift out of sync over a product’s life.
Cost-Savings and Efficiency Opportunities
Because SRRC and NAL overlap in samples, labs, and documentation, a well-sequenced program can materially cut cost and calendar time. The levers we see deliver the most value:
- Run testing in parallel where possible. NAL requires SRRC first for the final license, but much of the NAL testing can be initiated alongside SRRC type-approval testing, so the NAL application can be filed almost immediately after the SRRC certificate issues. This compresses two serial timelines into a largely overlapping one.
- Coordinate samples up front. SRRC samples can sometimes be reused for NAL. Even where separate samples are advisable for speed, planning the full sample count (SRRC + NAL) in a single build and shipment avoids a second customs cycle and a second round of in-China logistics.
- Prepare the Chinese-language document set once. The OEM agreement, manuals, datasheets, and label templates overlap substantially between the two filings. Building a clean, consistent Simplified-Chinese documentation package early — with matching model names, block diagrams, and operational descriptions — prevents the rework and rejections that drive most avoidable delay.
- Use pre-compliance RF testing. Surfacing RF issues before formal submission avoids costly official retests and the schedule slip that comes with them.
- Design the frequency plan to stay within LPD limits where feasible. If a function can be delivered within the micro-power short-range catalogue and its technical limits, it may avoid SRRC type approval altogether — a genuine cost and time saving. This has to be a design-phase decision.
- Engage one coordinated local partner. Because NAL requires a local certificate holder anyway, using a single coordinated in-country partner across both schemes reduces duplicated account setup, translation, and customs handling.
Bottom line: The savings come from treating SRRC and NAL as one integrated program rather than two sequential projects through shared samples, shared documents, overlapping test windows, and a single local partner.
Key Challenges for Manufacturers Entering the China Market
Even a well-run program encounters friction unique to China. Anticipating these challenges is what separates a predictable launch from a stalled one:
- The local-entity requirement for NAL. Foreign manufacturers cannot hold an NAL directly. Appointing and formalizing a trustworthy local representative with the right cooperation agreements and MIIT filings is often the longest-lead item and a strategic decision, not a clerical one.
- Mandatory in-country testing. There is no MRA with FCC, CE, or other foreign approvals. Samples must physically ship to China and test at accredited local labs, adding logistics, cost, and customs exposure that teams accustomed to test-data reuse often underestimate.
- Simplified-Chinese documentation burden. Many key documents must be in Simplified Chinese and internally consistent. Inconsistent model names, mismatched labels, or an out-of-scope ISO certificate are common causes of rejection.
- Tightening modular-approval rules. The assumption that a pre-certified module drops into a host product without further review is no longer reliable. Each host integration increasingly needs to be evaluated on its own, and integration testing should be planned and budgeted from the outset.
- Configuration and firmware lock. The certified configuration must match the shipped product exactly. Even a firmware change can invalidate an approval, so change control must account for certification impact.
- Customs and label matching. Customs will verify approval status and expect the physical product, labels, and shipping documents to match the certified configuration. Mismatches on the airway bill or label are a frequent, avoidable cause of held shipments.
- A moving regulatory target. China’s radio rules have been updated through a series of rolling MIIT notices (for example, the 2400/5100/5800 MHz interference-avoidance requirements and CMIIT ID coding changes). Requirements and validity terms shift, so monitoring official updates through certification should be part of the product lifecycle, not a one-time check.
- Renewal-calendar divergence. With SRRC at 5 years and NAL at 3, the two certificates fall due at different times. Without active tracking, a lapsed NAL can quietly cut off a compliant, still-selling product.
Conclusion
SRRC and NAL are best understood as two complementary keys to the same door. SRRC unlocks the right to transmit within China’s spectrum; NAL unlocks the right to connect to China’s public networks. Many wireless products need only the first, but any device that touches the cellular or public telecom network needs both, and because NAL is built on top of SRRC, the order and timing of the two are not interchangeable.
For manufacturers, the practical takeaways are consistent. Determine scope early, ideally in the design phase, so frequency bands and module choices can still be shaped around the requirements. Decide deliberately whether a low-power design path can keep a function outside SRRC’s scope entirely. Line up a capable local partner before you need one, since NAL cannot proceed without a local certificate holder. And run the two programs as one integrated effort with shared samples, a single Simplified-Chinese document set, and overlapping test windows to capture the real cost and schedule savings that sequential, siloed projects leave on the table.
China remains one of the most demanding Tier 1 markets to enter, but its requirements are navigable with the right preparation. Teams that treat SRRC and NAL as an early, coordinated part of product development, rather than a final compliance gate, reach the market faster, spend less, and avoid the customs holds, rejections, and lapsed certificates that catch less-prepared competitors.
