As a portable small appliance with electric heating functionality, an electric hand warmer usually needs to comply with multiple EU directives simultaneously.

The most essential of these are the Low Voltage Directive (LVD) and the Electromagnetic Compatibility Directive (EMC). In addition, it must also comply with environmental regulations such as the RoHS Directive on the restriction of hazardous substances. 

1. Core Certification Directives for Exporting Electric Hand Warmers to the EU

As a portable electrical appliance containing a heating element, electric hand warmers need to meet multiple directive requirements when exported to the EU.

The following are the core certification directives that electric hand warmers must comply with, as well as other regulations that may be applicable depending on the product characteristics.

1.1 Low Voltage Command (LVD)

Directive No. 2014/35/EU, which was fully implemented on April 20, 2016, replacing the previous 2006/95/EC Directive.

Scope of application: electrical equipment with rated voltages between 50–1000V AC (AC) or 75–1500V DC (DC). For electric hand warmers,Whether plug-in or rechargeable, as long as the operating voltage is within this range, it is regulated by LVD commands.

Core goal: To ensure that electrical equipment does not harm personal safety,Safety risks such as electric shock, fire, and mechanical injury caused by livestock or property.

 The LVD directive specifies the basic safety requirements that electrical equipment must meet, including insulation performance, grounding protection, leakage current, temperature rise, mechanical strength, and more.

Conformity assessment method: Manufacturers can adopt a self-declaration model, which proves product compliance with LVD directive requirements through internal quality control and third-party laboratory testing.No mandatory intervention from EU notified bodies is required. However, it should be noted that technical documents must be fully preserved for 10 years for inspection.

1.2 Electromagnetic Compatibility Directive (EMC)

Directive Number: 2014/30/EU

Scope of Application: All electrical and electronic equipment that may generate electromagnetic interference or be susceptible to electromagnetic interference.

As an electronic product containing electric heating elements and control circuits, the electric hand warmer must comply with the requirements of the EMC directive.

Core Content: The EMC directive includes two aspects of requirements:

Electromagnetic Emissions (EMI): The electromagnetic interference generated by the product during normal operation must not exceed the specified limits and must not interfere with the normal operation of other equipment.

Test items include radiated emissions, conducted emissions, etc.

Electromagnetic Immunity (EMS): The product should have sufficient resistance to electromagnetic interference and be able to operate normally in an environment with electromagnetic interference.

Test items include electrostatic discharge immunity, radio-frequency electromagnetic field radiation immunity, electrical fast transient/burst immunity, etc.

Conformity Assessment Method: Similar to LVD, the EMC directive also allows manufacturers to use a self-declaration approach to prove compliance through internal testing or testing by a third-party laboratory.

1.3 RoHS 2.0 Restriction of Hazardous Substances Directive

Directive Number: 2011/65/EU (RoHS 2.0), which fully replaced RoHS 1.0 on January 2, 2013;The four additional phthalate substances were mandatorily implemented on July 22, 2019.

Scope of Application: Electrical and electronic equipment and their raw materials and components. Electric hand warmers contain circuit boards, heating elements, plastic shells, etc., which fall under RoHS control.

Compliance Requirements: RoHS testing requires that products be disassembled into homogeneous materials for separate testing. Plastics, metals, PCB circuit boards, wire coatings, etc., need to be tested separately.

RoHS test reports are usually incorporated into the CE technical file (TCF) as supporting materials for the CE declaration of conformity.

1.4 Other Potentially Applicable Regulatory Requirements

In addition to the three core directives mentioned above, depending on the specific product form and function of the electric hand warmer, the following regulatory requirements may also apply:

(1) RED Radio Equipment Directive (2014/53/EU)

 If the electric hand warmer includes wireless functions such as Bluetooth, Wi-Fi, or wireless charging, it must comply with the RED directive requirements.

The RED directive itself already includes LVD and EMC requirements,so separate LVD and EMC compliance is not required, but it adds EMF (electromagnetic field) assessment and spectrum usage requirements.

(2) Battery Directive (2006/66/EC)

Rechargeable electric hand warmers contain lithium batteries and must comply with the EU Battery Directive, including battery labeling, hazardous substance restrictions, and recycling and disposal.

 Starting in 2024, the new battery regulation (EU 2023/1542) has officially come into effect, imposing stricter requirements on battery carbon footprint, removability, and recycling efficiency.

(3) REACH Regulation (EC 1907/2006)

REACH is the EU's regulation concerning the registration, assessment, authorization, and restriction of chemicals, with a broader scope of control than RoHS. The plastic casing, rubber parts,Chemical substances contained in materials such as surface coatings must comply with the REACH-SVHC (Substances of Very Concern) list, and if the amount exceeds 0.1%, notification obligations must be fulfilled.

(4) WEEE Directive (2012/19/EU)

This is the Waste Electronic and Electrical Equipment Directive, requiring manufacturers to take responsibility for the recycling and disposal of products after disposal,Products must have a "crossed trash bin" label affixed, and an authorized representative must be designated within the EU to handle recycling matters.

(5) General Product Safety Regulation (GPSR)

The EU 2023/988 General Product Safety Regulation will be fully applied starting December 13, 2024, requiring all consumer goods sold in the EU market to ensure safety.It also designates economic operators within the EU (such as importers and authorized representatives) to bear compliance responsibilities.

2. Detailed Explanation of Core Testing Standards

EU directives set out the basic safety requirements, while specific technical testing standards are detailed in the harmonized standards (EN standards) developed by the European Committee for Standardization (CEN/CENELEC).

For electric hand warmers, the most core testing standard is the EN 60335 series.

2.1 EN 60335-1: General Safety Requirements for Household Appliances 

EN 60335-1 is the general safety standard for household appliances, developed by the International Electrotechnical Commission (IEC) and adopted by the European Committee for Electrotechnical Standardization (CENELEC) as an EU harmonized standard.

All household appliance products must comply with this standard, which specifies the general safety requirements for household appliances.

The main test items include:

Classification and marking: The product's protection against electric shock category, and the completeness and durability of nameplate information.

Protection against access to live parts: Electric shock tests using test fingers, test pins, etc.

Input power and current: Verification of rated input power deviation.

 Heating (temperature rise test): Surface temperature limits of various components under normal operation.

 Leakage current and electrical strength at operating temperature: Insulation performance test in a hot state.

Moisture resistance: Moisture protection performance and electrical strength under humid conditions.

Leakage current and electrical strength (cold state): Insulation performance at normal temperature.

 Stability and mechanical hazards: Product stability and mechanical protection.

Mechanical strength: Mechanical stress tests such as drop and impact.

Structure: Internal wiring, insulation distance, creeping distance, and other structural safety requirements.

Internal wiring: Wire fixing and insulation protection.

Components: Certification and specification requirements for key components.

 Power connection and external flexible cords: Power cord specifications, connection methods, and tensile tests.

Creepage distance, clearances, and solid insulation: Safety margin of insulation distance.

Heat resistance and flame resistance: Heat and flame resistance of non-metallic materials (ball pressure test, needle flame test, etc.).

Note: The EN 60335 standard has been continuously updated in recent years. The 2023 version of the standard adds provisions for cybersecurity, comprehensively revises the safety requirements for battery-powered equipment, and gradually incorporates energy efficiency assessment requirements. Export companies should pay attention to the latest version of the standard to ensure that their products comply with the latest requirements.

2.2 EN 60335-2-30: Special Safety Requirements for Electric Heating Heaters

EN 60335-2-30 is a special safety requirement standard for electric heating heaters, serving as a supplement and elaboration of the general standard EN 60335-1.

As a portable electric heating device, the electric hand warmer must meet both general standards and special requirements.

This standard includes special testing requirements for electric heaters:

 Surface temperature limits: Specifies the maximum allowable temperature for different parts of the heater (such as the handle and surfaces in contact with skin) to prevent burns.

For electric hand warmers, the surface temperature in contact with skin is a core evaluation indicator.

Reliability of temperature control devices: Requires the heater to be equipped with both a thermostat and a thermal fuse for double protection, preventing overheating that could cause fire or burns.

Abnormal operation tests: Simulate abnormal conditions such as thermostat failure or the heater being covered to verify that the product remains safe under extreme conditions.

Special requirements for liquid-filled heaters: For liquid-filled hand warmers, pressure testing, sealing testing, and other special requirements must also be met.

Battery safety for rechargeable products: For rechargeable hand warmers with built-in batteries, safety protection against overcharge, over-discharge, and short circuits must be met.

Drop and impact: Portable products must pass drop tests to verify electrical safety performance after dropping.

Scope of application: EN 60335-2-30 applies to electric heaters with a rated voltage not exceeding 250V, including space heaters, radiant heaters, fan heaters, electric blankets, hand warmers, and other types of electric heating products. Specific clauses vary depending on the type of heater.

2.3 EMC Related Testing Standards

Under the EMC directive, electric hand warmers need to meet the testing requirements of the following series of standards:

The EN 55014 series is the electromagnetic compatibility standard for household appliances, electric tools, and similar equipment, and serves as the main basis for the EMC testing of electric hand warmers.

Testing must be conducted in laboratories accredited with ISO 17025, and the test report serves as an important part of the CE technical documentation.

3. Complete CE certification process

The process for applying for CE certification for electric hand warmers can be divided into the following six steps:

Step 1: Confirm applicable directives and testing standards

First, based on the product's functions, voltage, and whether it includes a wireless module, determine which EU directives and corresponding harmonized standards the product must comply with.

For conventional hand warmers, the core is LVD, EMC, and RoHS; If it has wireless functionality, it must be handled according to RED instructions;If it's rechargeable, battery commands should also be considered.

Step 2: Choose a certification body and laboratory

Choose a third-party testing laboratory with ISO 17025 certification for testing. For LVD and EMC directives,

Companies can choose the self-declaration model, which involves commissioning a qualified laboratory to issue test reports,

The manufacturer must sign the declaration of conformity themselves; Alternatively, certificates can be issued by EU notified bodies to enhance the credibility of the certification.

Important Reminder: Be sure to choose a qualified and experienced accredited laboratory. Improper test reports may not be recognized during customs checks or market supervision sampling in the European Union, which could result in products being detained or removed from the shelves. It is recommended to prioritize laboratories with CNAS/CMA accreditation that cooperate with a notified body in the EU.

Step 3: Prepare Technical Documents and Samples

Submit an application form, product technical documents (manual, circuit diagram, BOM, nameplate, etc.), and 2-3 production-ready test samples to the laboratory. The laboratory will determine specific test items and standards based on the product characteristics and provide a quotation and timeline.

Step 4: Product Testing

The laboratory will perform a full set of tests on the samples according to the relevant standards, including:

LVD Electrical Safety Testing (insulation, voltage withstand, temperature rise, mechanical strength, flame retardancy, etc.)

EMC Electromagnetic Compatibility Testing (conducted/radiated emissions, electrostatic/radio frequency/pulse group immunity, etc.)

RoHS Harmful Substances Testing (tested according to homogeneous materials)

If any non-compliance is found during testing, the company must rectify the product and resend it for testing until all items pass.

Step 5: Prepare Technical Documentation (TCF)

After all tests have passed, a complete CE Technical Construction File (TCF) must be prepared, including:

- Product description and specifications

- Design schematics, circuit diagrams, and PCB layout diagrams

- Bill of Materials (BOM) for key components and datasheets

- Risk assessment report

- Test reports (LVD, EMC, RoHS)

- Product user manual (in English / language of the target EU market)

- Product nameplate and label design drawings

- List of applicable harmonized standards

The technical documentation must be retained for 10 years, and EU market regulatory authorities have the right to inspect it at any time.

Step 6: Sign the Declaration of Conformity and Affix the CE Mark

The manufacturer signs the EU Declaration of Conformity, declaring that the product complies with all applicable EU directive requirements.

Then, the CE mark is affixed to the product nameplate, packaging, and manual, allowing the product to be legally sold in the EU market.

CE Mark Requirements: The CE mark must be affixed to the product in a clear, distinguishable, and non-erasable manner;

 the height of the mark must be at least 5mm; 

The proportions of each component must comply with the regulations (the height ratio of C and E).

 The shape or proportion of the CE mark must not be arbitrarily altered.

4. Common Questions and Precautions

Q1: How long does it take to obtain CE certification for an electric hand warmer?

Under normal circumstances, the full set of LVD, EMC, and RoHS certification tests takes about 2-4 weeks. If any non-conforming items are found during testing and need to be rectified, the time will be correspondingly extended.

It is recommended that companies allow sufficient time to avoid affecting the shipping schedule.

Q2: How much does CE certification cost?

The certification cost varies depending on the product complexity, number of test items, and whether rectifications are required.

For a regular electric hand warmer, CE certification (LVD, EMC, RoHS) usually costs several thousand to over ten thousand RMB.

Products with wireless functions require testing according to the RED directive, which will increase the cost. It is recommended to provide the laboratory with detailed product information to obtain an accurate quotation.

Q3: What is the validity period of CE certification?

CE certification itself does not have a fixed validity period. As long as the product design, materials, and processes remain unchanged, and the applicable EU directives and standards are not updated, the certification remains valid. However, if there are significant changes to the product or updates to the applicable standards, re-evaluation and possibly supplemental testing will be required.

Q4: If one model has CE certification, can other models share it?

In principle, CE certification is issued per model. If multiple models are basically identical in circuit design, core components, and product structure, with only differences in appearance color or power levels, series certification can be applied for. The main inspection model serves as the basis, and other models undergo a difference assessment, without the need for full retesting.

Q5: What special CE certification requirements do e-commerce platforms like Amazon have?

Amazon EU requires all electronic and electrical products to provide CE certification documents, including test reports, declarations of conformity, and EU responsible person information.

Since July 2021, EU market regulation requires that all products exported to the EU must designate an economic operator (such as an importer or authorized representative) within the EU,Label the product or packaging with its name and contact information. Amazon regularly conducts spot checks, and non-compliant products will be taken down.

EU Responsible Person: According to the EU Market Regulation (EU 2019/1020), starting from July 16, 2021,All products bearing the CE mark must have an economic operator responsible for product compliance within the EU. If the manufacturer is not in the EU,An authorized representative or importer within the EU must be designated as the responsible person, and their name and contact address must be indicated on the product.

Q6: What should I do if the test fails?

If any nonconformities are found during testing, the laboratory will issue rectification recommendations. The company will design the product or make material corrections based on the suggestions before resending the test.

Common nonconformities include: excessive temperature rise, voltage breakdown, excessive EMI radiation, and insufficient creepage distance of the structure.

It is recommended to introduce safety review during the product design phase to reduce the cost of later rectification.

Q7: What is the difference between CE certification and CB certification?

CE certification is a mandatory entry requirement for the EU market and can only be used within the EU. CB certification is an international mutual recognition system launched by the International Electrotechnical Commission (IECEE),Currently, more than 50 member countries have reported mutual recognition of the CB. After obtaining the CB report, it can be converted to multinational certification (such as EU CE, US FCC, Japan PSE, etc.),Reduce the cost of repeated testing. It is recommended to obtain CB certification first before transferring to certifications of other countries.

5. Conclusion

Although the certification of electric hand warmers for export to the EU involves multiple directives and standards, it is actually not complicated as long as one clarifies the process and proceeds step by step.

To summarize the key points:

LVD, EMC, and RoHS are the "trio" of CE certification for electric hand warmers, all of which are indispensable;

The core testing standards are EN 60335-1 (general safety) and EN 60335-2-30 (special requirements for electric heaters);

Devices with wireless functionality should follow the RED directive, and rechargeable models must also comply with battery regulations;

It is crucial to choose a qualified and legitimate laboratory to avoid the customs clearance and sales risks associated with "fake reports";

Do not forget to designate an EU Responsible Person, which is a mandatory requirement for platforms like Amazon and for customs;

Technical documentation should be kept for 10 years, ready to respond to market regulatory inspections at any time.

With the strengthening of EU market supervision, compliance is no longer an "optional" matter but a "survival baseline" for exporting companies.

It is recommended that companies introduce compliance reviews during the product design stage to control product quality from the source and avoid time and cost losses caused by later rectifications.

Choosing a professional and reliable testing and certification partner can also make the export process smoother.
