This guide covers: major certifications by region — Japan PSE and Giteki (POINT 01), US FCC Part 15 and FCC ID (POINT 02), European CE marking and its constituent directives (POINT 03), China CCC and other regional certifications (POINT 04) — followed by the step-by-step certification process flow (POINT 05), cost reference by certification type (POINT 06), and four practical compliance notes that prevent the most common expensive mistakes (POINT 07).
Japan has two distinct certification systems for electronics that operate independently and apply to different product characteristics. Many products require both.
🇯🇵 Japan
PSE
Electrical Appliance and Material Safety Law (電気用品安全法)
Approximately 450 product categories of electrical appliances are subject to PSE. Two compliance tiers apply: Specified Electrical Appliances (特定電気用品) — marked with a diamond-shaped PSE symbol — require third-party certification by an accredited body before the mark can be affixed. Other Electrical Appliances (特定電気用品以外) — marked with a circular PSE symbol — allow manufacturer self-declaration after in-house testing against applicable standards. Covered products include power supplies, AC adapters, battery chargers, and a wide range of consumer electronics.
Products sold in Japan without PSE where required are illegal to distribute — importers bear the compliance responsibility.

技適
Technical Conformity Certification (技術基準適合証明)
Giteki is required for any electronic product incorporating intentional wireless transmission capability: Wi-Fi (2.4 GHz and 5 GHz), Bluetooth (Classic and LE), LTE/4G/5G cellular, Zigbee, Z-Wave, 920 MHz band IoT protocols, and any other radio technology regulated under Japan's Radio Act. Operating a device without Giteki in Japan violates the Radio Act, regardless of whether the device was legally certified in its country of origin. The Giteki mark (丸に技) must be visible on the device or accessible through a software menu for devices where physical labeling space is insufficient.
Foreign certification (FCC, CE RED) does not substitute for Giteki — a separate Japan-specific certification is always required for wireless products.
PSE + Giteki for most modern consumer electronics: Any product with wireless connectivity and a power input — a smart home device, an IoT sensor, a wireless audio product — will require both PSE (for the electrical safety aspects) and Giteki (for the radio). Plan both certifications into the product timeline simultaneously, as PSE and Giteki are independent processes with separate test laboratory engagements. The combined timeline from sample submission to marks approval is typically 3–5 months for standard products.
FCC (Federal Communications Commission) certification covers electromagnetic compatibility and radio frequency compliance for products sold in the US market. The applicable path depends on whether the product intentionally transmits radio signals.
🇺🇸 United States
FCC Part 15
Unintentional Radiators — SDoC or Third-Party Certification
Part 15 Subpart B covers digital devices that generate RF as an incidental byproduct of their operation — computers, displays, switching power supplies, microcontrollers, and similar products. Class A devices (industrial or commercial use): can be authorised by Supplier's Declaration of Conformity (SDoC) or third-party certification. Class B devices (residential or home use): require SDoC or third-party certification; Class B limits are more stringent than Class A. The FCC mark or FCC compliance statement must appear in product documentation.
Class B limits are significantly stricter than Class A — design and test against Class B from the start if there is any chance the product will be used in residential environments.
🇺🇸 United States
FCC ID
Intentional Radiators — Third-Party Certification Required
Products that intentionally transmit radio signals — Wi-Fi, Bluetooth, Zigbee, cellular modems, RF remotes — require FCC ID certification through an accredited Telecommunications Certification Body (TCB). The FCC ID is a unique alphanumeric identifier assigned to the specific product configuration; it must be printed on the device label and included in user documentation. FCC ID certification cannot be self-declared — it always requires third-party testing and TCB approval. Modules with existing FCC IDs can simplify the certification process: a product using a pre-certified Wi-Fi/Bluetooth module may only need integration testing rather than full RF certification, if the module's FCC ID grant conditions are followed.
Using a pre-certified radio module does not automatically transfer FCC certification to the end product — check the module's grant conditions carefully.
CE marking is a conformity mark required for most electronic products sold within the European Economic Area (EEA). Unlike a single certification body approval, CE marking is a manufacturer's self-declaration that the product complies with all applicable EU directives and regulations. The CE mark does not indicate that a specific third party has tested and approved the product — the manufacturer takes legal responsibility for compliance. However, the underlying testing to verify compliance must typically be conducted at accredited laboratories.
EMC
EMC Directive 2014/30/EU: Applies to virtually all electronic products. Requires the product to not generate electromagnetic interference above defined limits (emissions) and to operate correctly in the presence of electromagnetic disturbance (immunity). Testing covers conducted and radiated emissions and a suite of immunity tests (ESD, surge, burst, etc.).
LVD
Low Voltage Directive 2014/35/EU: Applies to electrical equipment designed for 50–1000 V AC or 75–1500 V DC input. Covers electrical safety — protection against electric shock, fire, and mechanical hazards from the electrical supply. Most mains-powered electronics are subject to both LVD and EMC.
RED
Radio Equipment Directive 2014/53/EU: Applies to any product intentionally emitting or receiving radio waves — replaces the older R&TTE directive. Covers Wi-Fi, Bluetooth, cellular, and all other radio technologies. Products with radio require RED in addition to (not instead of) EMC compliance. Notified Body involvement may be required when harmonised European standards are not fully applied.
RoHS
RoHS Directive 2011/65/EU (recast): Restricts the use of ten hazardous substances (lead, mercury, cadmium, hexavalent chromium, PBBs, PBDEs, and four phthalates) in electrical and electronic equipment. Compliance requires documentation of restricted substance levels in all homogeneous materials. RoHS applies across virtually all EEE categories and is required in addition to EMC and LVD.
REACH
REACH Regulation (EC) 1907/2006: Covers the registration, evaluation, and authorisation of chemical substances. Relevant to electronics manufacturers through SVHC (Substances of Very High Concern) disclosure obligations — if an article contains an SVHC above 0.1% by weight, customers and consumers must be notified. REACH is not a pre-market approval scheme but an ongoing substance tracking and disclosure obligation.
⚠ "China Export" is not CE marking: A mark sometimes affixed to electronics manufactured in China that visually resembles the EU CE mark uses a wider letter spacing — it stands for "China Export" rather than European conformity. Products bearing this mark are not CE-certified. Distributing electronics in the EU with a false or non-compliant CE mark is illegal and carries significant penalties. Always verify that a product's CE mark is accompanied by a valid EU Declaration of Conformity and test reports from an accredited laboratory.
Beyond the US, EU, and Japan, several major markets have their own mandatory certification systems. Products targeting multiple markets simultaneously must obtain each market's required certifications independently.
🇨🇳 China
CCC
China Compulsory Certification (中国強制認証)
CCC applies to approximately 140 product categories in the Chinese market — consumer electronics, IT products, telecommunications equipment, electrical accessories, and others. CCC is administered by CNCA (Certification and Accreditation Administration of China) and can only be obtained through designated Chinese certification bodies. The process requires: product testing at a designated Chinese test laboratory, a factory inspection at the manufacturing facility, and an ongoing annual surveillance audit. For foreign manufacturers, a Chinese agent or legal entity must be designated as the certificate holder.
CCC cannot be obtained at international laboratories — testing must occur at CNCA-designated facilities in China. Timeline: 3–6 months for initial certification.
🌏 Other Regions
KC / BSMI / RCM
Korea · Taiwan · Australia/New Zealand
KC (Korea Certification): Required for electrical and electronic products sold in South Korea, administered by KEIT. Covers safety and EMC requirements comparable to CE/FCC. BSMI (Taiwan): Bureau of Standards, Metrology and Inspection certification required for IT equipment, power supplies, and other electronics in Taiwan. RCM (Regulatory Compliance Mark): Australia and New Zealand require RCM for electrical equipment and products using radio communications — covers both electrical safety (previously C-Tick and A-Tick marks, now consolidated). Each requires independent testing and registration in the target country.
Multi-market launches should map all required certifications before design freeze — some testing (particularly EMC) produces data usable across multiple markets.
Efficiency through testing overlap: EMC test data — emissions and immunity measurements — generated for one certification often covers the test requirements of another. A product tested for FCC Part 15 Class B will have emissions data largely applicable to CE EMC compliance; the same test samples and lab sessions can address both with proper planning. Discuss multi-market test efficiency with your accredited laboratory at the project scoping stage, before samples are submitted — the cost savings from consolidated testing can be substantial compared to running independent test campaigns for each market.
Certification is a sequential process where each stage depends on the one before it. Compression or shortcuts at early stages — particularly regulatory research and pre-compliance design — reliably create expensive failures at the testing stage. The flow below applies to any regional certification; the specific test standards, laboratory requirements, and timelines vary by market.
Regulatory Research — Before Design Freeze
Identify all target sales markets and determine which certifications apply to your specific product category and feature set. Key variables: the product's rated voltage and current (determines LVD/PSE scope), presence of wireless communication (determines FCC ID/Giteki/RED/CCC radio requirements), product category (determines whether CCC, BSMI, or KC applies), and end-use environment (industrial vs. residential determines FCC Class A vs. B). Completing this research before design freeze allows compliance requirements to be incorporated into the PCB layout and component selection — catching EMC and safety issues in the design rather than in the test lab.
Pre-design inputAll target markets
Pre-Compliance Testing — During Design
Pre-compliance testing uses the same test equipment and measurement methods as formal certification testing but is conducted informally — typically at the design team's own facility or a pre-compliance testing service — to identify emission and immunity problems before formal test submission. A product that passes pre-compliance testing at comfortable margin has a significantly higher probability of first-pass formal test success. Pre-compliance testing for EMC costs a fraction of a failed formal test campaign with associated redesign and re-test cycles.
Before formal submissionReduces re-test risk
Test Laboratory / Certification Body Selection
For multi-market certification, use internationally accredited laboratories (TÜV, UL, SGS, Intertek, Bureau Veritas, TÜV Rheinland) that can handle multiple regional certifications from a single engagement — reducing sample shipments, logistics costs, and coordination overhead. For CCC specifically, confirm that the laboratory holds CNCA designation. For Giteki, confirm accreditation by Japan's MIC (Ministry of Internal Affairs and Communications). Request a test plan from the laboratory before submitting samples — this documents exactly which standards will be applied and which tests are included.
Accreditation scope matchMulti-market consolidation
Production-Representative Sample Preparation
Certification testing must be performed on samples that are identical to the final production configuration: same PCB revision, same firmware version, same enclosure and labeling, same accessories included in the product package. Early engineering prototype samples may not reflect the final product's EMC performance — antenna placement, shield design, and power supply layout changes between prototype and production can significantly affect test results. Submitting a pre-production sample whose design has not been finalised risks passing a test for a configuration that will not be manufactured.
Final PCB revisionFinal firmwareNot prototypes
Formal Testing
Testing duration by certification type: EMC testing for CE (emissions + immunity suite): 2–4 weeks. FCC Part 15 radiated and conducted emissions: 1–3 weeks. FCC ID RF performance testing: 3–6 weeks. PSE electrical safety testing: 3–6 weeks. Giteki radio testing: 4–8 weeks. CCC (including factory inspection scheduling): 3–6 months. Products with multiple wireless technologies (Wi-Fi + Bluetooth + LTE) or multiple market requirements in parallel will require longer test windows. Confirm current test queue times with the laboratory when planning the certification schedule.
EMC: 2–4 weeksFCC ID: 3–6 weeksCCC: 3–6 months
Failure Remediation
If the product fails any required test, the root cause must be identified, a design fix implemented, and the relevant tests repeated. Common EMC failure causes in electronic products: insufficient decoupling on power planes, clock harmonics radiating from long traces, inadequate shielding continuity, and common-mode choke dimensioning on power inputs. Antenna-related failures in wireless products often trace to impedance mismatch, ground plane sizing, or proximity to metallic enclosure elements. Document all changes between test sessions in the Technical File — undocumented modifications between a failed test and a passed re-test create compliance documentation gaps.
Root cause analysisDocument all changes
Certification Issuance and Label Application
After passing all required tests, the certification body issues the certificate, test report, or grant of equipment authorisation (for FCC ID). The applicable marks — CE, FCC ID, PSE, Giteki, CCC — must be applied to the product in compliance with each certification's labeling specifications: minimum mark dimensions, placement on the product body vs. documentation, accompanying text requirements, and format of the FCC ID string. Labeling non-compliance can result in a product being treated as non-certified even when all tests have been passed — review labeling requirements before finalising the product enclosure and label artwork.
Mark dimensions specifiedProduct body placement
Ongoing Compliance Management
Certifications are not one-time events — they require ongoing maintenance. CCC requires annual factory surveillance audits and periodic factory inspections. CE marking requires the Technical File to be updated when the product or its applicable standards change. Any design change that could affect test results must be assessed against the original certification scope before the modified product is placed on the market. Establish a design change review process that routes all product modifications through a compliance check before production release.
CCC: annual auditAll certs: design change review
Certification costs are one of the most frequently underestimated line items in electronics product development budgets. The ranges below reflect test laboratory and certification body fees for products of moderate complexity. Simple products tested against a single standard at the lower end of the complexity range may cost less; products with multiple wireless technologies, multiple power input ranges, or targeted at multiple markets simultaneously will cost significantly more.

Multi-market cost reality: A product targeting the US, EU, Japan (wired), and Japan (wireless) markets simultaneously with Wi-Fi and Bluetooth — a typical IoT device — will accumulate: CE (EMC + LVD + RED), FCC Part 15 + FCC ID (Wi-Fi + Bluetooth), PSE, and Giteki. Total testing and certification cost: USD 40,000–100,000 before any redesign costs. This budget needs to be planned at the product brief stage, not discovered during pre-launch. Certification cost is a non-negotiable cost of market entry, not a variable to optimise away.
PITFALL 1
Design changes after certification trigger re-certification
Any design modification that could affect electromagnetic emissions, immunity performance, electrical safety, or radio performance may require partial or full re-testing. Even minor changes — substituting an equivalent component from a different supplier — can alter EMC behaviour measurably. Establish a formal design change review process that evaluates every proposed change against the certification scope before implementing it. The cost of an undisclosed post-certification design change discovered in a market surveillance inspection is substantially higher than the cost of a planned re-test.
PITFALL 2
Some certifications have renewal and audit obligations
CCC requires annual factory surveillance audits — failure to maintain these invalidates the CCC certificate, meaning the product cannot legally be sold in China until the audit is reinstated. Several other certifications have review cycles when the applicable harmonised standards are revised. Build certification renewal dates and audit schedules into the product's lifecycle management calendar. Budget for ongoing maintenance costs — these are predictable and should not be surprises.
PITFALL 3
Labeling errors invalidate compliant products
A product that passed all required tests but whose CE mark is the wrong size, whose FCC ID is in the wrong format, whose PSE mark appears on the package rather than the product body, or whose Giteki mark is not accessible through the device software may be treated as non-compliant in market surveillance. Review each certification's specific labeling requirements with the test laboratory before the product enclosure artwork and label artwork are finalised — after the enclosure tooling is cut is too late for free changes.
PITFALL 4
Pre-certified modules do not certify the end product
Using a pre-certified Wi-Fi or Bluetooth module (one with its own FCC ID or CE RED declaration) significantly reduces the radio-specific testing scope — but does not eliminate the need for end-product certification entirely. The end product must still obtain its own FCC ID (or demonstrate compliance with the module's integration requirements), and must still pass EMC testing as an integrated system. Integration of a pre-certified module into a product can introduce new emissions from the host system that the module's original certification did not account for.
⚠ Fake certification marks are a legal liability: Affixing a certification mark — CE, FCC, PSE, Giteki, CCC — to a product that has not actually obtained that certification is illegal in every market that recognises the mark, and carries penalties ranging from fines to import bans to product recalls. This includes using a "CE"-like mark that resembles the EU conformity mark but represents "China Export" rather than European conformity. If a supplier provides products with pre-applied certification marks that you cannot verify, request the supporting test reports and certificates before those products enter your supply chain. Responsibility for certification compliance rests with the party placing the product on the market — which, for imported products, is typically the importer, not the manufacturer.
Summary
Electronics product certification is a market entry requirement — not optional, and not a post-design task. Research applicable certifications for all target markets before design freeze, and incorporate EMC and safety design requirements during PCB layout. Japan requires PSE for electrical appliances and Giteki for any wireless product — both independently. The US requires FCC Part 15 for all digital electronics and FCC ID for any intentional radio transmitter. The EU requires CE marking covering EMC, LVD (if mains-powered), RED (if wireless), and RoHS for all relevant electronics. China requires CCC for approximately 140 product categories with mandatory in-China testing and factory inspection. Plan certification costs — typically USD 40,000–100,000+ for a multi-radio, multi-market consumer product — at the product brief stage. Run pre-compliance testing during design to reduce first-pass test failure risk. Review labeling requirements before enclosure artwork is finalised. Establish a design change review process that routes all post-certification modifications through a compliance check before production release.
