A small electrical product with a lithium battery does not follow one universal “GPSR + CE + UN 38.3” route. The legal route depends on voltage, radio functions, electromagnetic behaviour, materials, battery configuration, intended use and the countries where the product is sold.

The distinction is commercially important. The European Commission recorded **4,671 Safety Gate alerts in 2025**, and electrical appliances and equipment represented **11%** of them. A battery test summary or a CE logo cannot replace a product-specific scope decision.

## Does GPSR apply to small electrical and lithium-battery products?

**GPSR can apply, but it does not replace electrical, radio, chemical or battery legislation.** Under GPSR Article 2, product-specific EU safety rules control the risks they already cover. GPSR complements them for uncovered risks and applicable horizontal duties, including distance-sales information.

The manufacturer should therefore classify the complete product and every supplied component before choosing standards, tests, declarations or warnings. “Powered by USB” and “contains a lithium battery” are product facts, not legal classifications.

## Which EU rules apply to a small electrical product?

| Product example | Rules commonly requiring a scope decision | CE consequence | Evidence to check first |
| --- | --- | --- | --- |
| 5 V USB device without radio or battery | GPSR; EMC where the apparatus can emit or be affected by disturbance; RoHS and WEEE where it is EEE | LVD normally does not apply to the 5 V side, but EMC or RoHS can still require CE | Rated input/output, circuit and EMC behaviour, materials, intended use |
| 100–240 V mains-to-USB adapter | LVD, EMC, RoHS, ecodesign requirements where applicable; GPSR complementarity | Normally CE and an EU Declaration of Conformity under the applicable harmonisation acts | Electrical safety design, insulation, thermal protection, EMC and material evidence |
| Bluetooth, Wi-Fi or other radio device | RED, RoHS, WEEE, Batteries Regulation if a battery is included; applicable GPSR duties | RED requires CE and covers health/safety without the LVD voltage limit, EMC and radio-spectrum use | Radio module integration, antenna, software, RF exposure, safety and spectrum evidence |
| Device with an incorporated portable lithium battery | Product rules above plus Regulation (EU) 2023/1542; transport rules when shipped | The battery has its own conformity route; the complete product's CE status follows every applicable act | Battery EU DoC/CE evidence, model identity, safety data, UN 38.3 summary and integration risks |
| Electrical product sold across EU countries | Product rules plus WEEE and battery extended producer responsibility where applicable | EPR registration is not a CE mark, but can still be required before sale | Target countries, producer status, national registrations and reporting route |

The [Low Voltage Directive](https://eur-lex.europa.eu/eli/dir/2014/35/2026-05-30/eng) covers equipment designed for **50–1,000 V AC** or **75–1,500 V DC**. A 5 V USB device is normally below that range. Its 100–240 V adapter is a separate scope question, and a radio product under RED follows the RED safety requirement without those voltage limits.

The [EMC Directive](https://eur-lex.europa.eu/eli/dir/2014/30/2026-05-30/eng) does not “guarantee compatibility with electromagnetic fields.” It limits emissions and requires adequate immunity for apparatus in scope. [RoHS](https://eur-lex.europa.eu/eli/dir/2011/65/2026-07-01/eng) restricts specified hazardous substances in EEE; it is not a general product-safety test.

## Does a 5 V USB product need CE marking?

**A 5 V rating excludes neither CE marking nor an EU Declaration of Conformity.** It usually takes the product itself outside the LVD voltage range, but EMC, RoHS, RED or the Batteries Regulation may still require conformity assessment, an EU Declaration of Conformity and CE marking.

The complete configuration matters. A passive cable, a 5 V lamp, a power bank, a Bluetooth tracker and a mains adapter do not share one conformity route. If a mains adapter is supplied in the box, review the adapter's conformity evidence and assess the hazards created by using it with the product.

## Is UN 38.3 enough for EU sale or air transport?

**No. UN 38.3 is transport test evidence, not EU market approval and not automatic airline acceptance.** The UN Manual of Tests and Criteria uses eight test types for lithium cells and batteries. The test summary identifies the manufacturer, laboratory, report, battery type, mass, watt-hour rating or lithium content, model numbers, tests and results.

| Evidence or decision | What it answers | What it does not prove |
| --- | --- | --- |
| UN 38.3 test report and test summary | Whether the tested cell or battery type met the applicable UN transport test sequence | EU product compliance, CE conformity, safe integration into the finished device or carrier acceptance |
| EU product conformity file | Whether the complete product and battery meet the applicable EU legislation | That the packed consignment meets current air, road, sea or postal transport rules |
| 2026 IATA classification and packing decision | UN number, battery configuration, watt-hour or lithium limits, state of charge, packing, marks, documents and operator variations | General EU product safety or market access |

The applicable transport instruction changes with lithium-ion versus lithium-metal chemistry, batteries shipped alone, packed with equipment or contained in equipment, capacity and transport mode. Use the current carrier and dangerous-goods rules for each consignment; passing UN 38.3 alone does not authorise shipment.

## What does the EU Batteries Regulation require in 2026 and 2027?

Regulation (EU) 2023/1542 is wider than recycling. It covers battery safety, restricted substances, conformity assessment, CE marking, information, producer responsibility and end-of-life duties. A product manufacturer should obtain evidence that identifies the exact battery model and should not rely on an anonymous cell data sheet.

Since **18 August 2025**, batteries must bear the separate-collection symbol, subject to the Regulation's placement rules. Batteries Regulation Article 13 uses a conditional start date for general and capacity labels: 18 August 2026 or 18 months after the relevant implementing act enters into force, whichever is later. Do not assume the calendar date alone activates every label field.

From **18 February 2027**, Batteries Regulation Article 11 generally requires portable batteries incorporated into products to be readily removable and replaceable by the end user, with defined exceptions and a professional-replacement route for certain products. The product must also carry permanent online removal, replacement and safety information. A battery passport is not required for every small portable battery; from that date it applies to LMT batteries, industrial batteries above 2 kWh and electric-vehicle batteries.

## Which warnings belong on the product or instructions?

There is no universal legal list containing “keep away from fire,” “use only the supplied charger” and “do not use a damaged battery” for every electrical product. Warnings must follow the identified hazards, foreseeable use, applicable law, standards, battery chemistry and protection design.

A defensible warning record links each instruction to a hazard and control. Typical assessment topics include charging temperature, compatible input, cell damage or swelling, short circuit, water ingress, ventilation, child access, disposal and what the user must do after a fault. Design controls come before warnings; a label should not be used to excuse an avoidable hazard.

## What must an online electrical-product offer show?

GPSR Article 19 can require the online offer to show the manufacturer's name or trade name and postal and electronic address; the EU responsible economic operator where required; product identification and an image; and applicable warnings or safety information. CE, battery and WEEE symbols on the physical product do not replace those online fields.

Keep a dated capture of the listing in the technical file. The [GPSR online-sales guide](https://eugpsr.de/en/blog/gpsr-online-sales-required-info) explains the field-level check, while the [technical-documentation guide](https://eugpsr.de/en/blog/gpsr-technical-documentation-contents) separates a product file from a generic certificate.

## What should be checked before EU sale?

| Step | Decision or record | Main failure to avoid |
| ---: | --- | --- |
| 1 | Fix intended use, users, variants, supplied adapter and battery model | Classifying only the marketing name |
| 2 | Map GPSR, LVD, EMC, RED, RoHS, Batteries, WEEE and any product-specific rules | Treating every electrical product as the same |
| 3 | Select the conformity route and current standards for each applicable act | Assuming one supplier certificate covers the finished product |
| 4 | Document electrical, thermal, fire, charging, mechanical, chemical, EMC and foreseeable-use risks | Replacing design controls with generic warnings |
| 5 | Match test reports, EU declarations and supplier evidence to exact models and variants | Accepting reports with a different cell, board, adapter or enclosure |
| 6 | Obtain the UN 38.3 test summary and set the current transport route | Treating UN 38.3 as airline approval |
| 7 | Finalise product, battery and WEEE markings, instructions and language versions | Copying symbols or warnings without a legal basis |
| 8 | Verify the EU economic operator, online offer and national EPR registrations | Assuming CE registration covers waste obligations |

Use the [GPSR risk-assessment method](https://eugpsr.de/en/blog/gpsr-risk-assessment-methodology) to record hazards and controls. The technical file should preserve the evidence behind each decision, not only the final label and declaration.

## Frequently asked questions about small electrical and lithium-battery products

### Does a 5 V USB product fall under the Low Voltage Directive?

Usually not on its 5 V DC rating. The LVD covers 75–1,500 V DC and 50–1,000 V AC, but an included mains adapter can fall within it. EMC, RoHS, RED or battery rules may still require CE marking.

### Is UN 38.3 enough to sell a lithium-battery product in the EU?

No. UN 38.3 supports transport classification. It does not replace EU product conformity, technical documentation, risk controls, CE marking where required or current carrier rules.

### Does every USB charger need CE marking?

A mains-powered USB adapter normally falls under CE-requiring harmonisation law. A passive cable or low-voltage DC charging circuit may follow a different scope. Review each supplied component and the complete product.

### Which documents should a lithium-battery product file contain?

Keep the law-scope decision, risk assessment, designs and components, relevant tests and supplier evidence, EU declarations, battery documents, UN 38.3 summary, labels, instructions, online-offer capture and EPR records applicable to the target countries.

### Can Grüner Baum review a small electrical or lithium-battery product?

Yes. [Grüner Baum GmbH](https://eugpsr.de/en/gpsr-compliance-services) can map the applicable EU rules, review the risk analysis and technical file, check labels and online offers, and assess the Article 16 EU economic-operator route. Laboratory, battery-transport and product-specific conformity work is scoped to the device and available evidence. [Request an electrical-product compliance review](https://eugpsr.de/en/contact).
