What a Declaration of Conformity Must List
Quick answer
A Declaration of Conformity (DoC) must list the manufacturer's identity, the product model, the applicable EU/UK directives or US regulations, the harmonized standards applied, and a dated signature from an authorized representative. For private-label wellness devices, the typical DoC covers 6-10 standards and takes 2-3 weeks to compile after final product testing.
- A DoC is a legally binding document signed by the manufacturer or authorized representative, not by the importer.
- Every DoC must identify the product by model number, batch/serial range, and description.
- The document must cite the specific EU directives (e.g., 2014/30/EU for EMC, 2014/35/EU for LVD) or US regulations applicable to the product.
- Harmonized standards (EN, IEC) must be listed with their exact reference numbers and dated versions.
- The signatory's name, position, and place of signature are mandatory — typically an authorized representative in the EU or UK.
- LIGHT BDB provides DoC documentation at no extra cost for all ODM orders over 500 pieces, with a 7-day turnaround after test reports.
- A Declaration of Conformity is not the same as a test report — it declares conformity, while the test report proves it.
What exactly does a Declaration of Conformity do for my product?
A Declaration of Conformity is your legally binding statement that a product meets all applicable EU or US regulatory requirements, signed by the responsible manufacturer or their authorized representative. It is the document customs officers and market surveillance authorities ask for first when you import wellness devices into the EU or UK. Without it, your shipment can be held at the border, and in some cases, products are destroyed if the DoC references incorrect directives or standards.
For a private-label brand, the DoC serves two roles simultaneously. First, it is your legal passport to place the product on the market — customs will scan the document's reference numbers against their databases. Second, it transfers liability: whoever signs the DoC is the legal manufacturer under EU law, which is why most US and JP brands ask their ODM partner to sign as the authorized representative. LIGHT BDB signs DoC documents for its private-label clients as the manufacturer of record, with your brand name listed as the responsible party in your own territory.
Which sections must a compliant Declaration of Conformity include?
A compliant Declaration of Conformity must include eight essential sections: manufacturer identity, product identification, directive references, harmonized standards, notified body involvement (if any), the signatory's details, the place and date of issue, and the legal declaration statement itself.
Here is the complete list, in the order most conformity assessment bodies expect to see it:
- 1. Manufacturer or authorized representative — legal name, full address, and contact details of the entity issuing the DoC.
- 2. Product identification — model number, type/batch/serial number, and a plain-language description of the product (e.g., "heated eye massager with vibration function").
- 3. Directives/regulations applied — e.g., EU 2014/30/EU (EMC), 2014/35/EU (LVD), 2011/65/EU (RoHS), 2009/125/EC (ErP), or the UK's corresponding SI regulations.
- 4. Harmonized standards used — exact standard references with year, such as EN 55014-1:2017, EN 60335-1:2012/A2:2019, or EN IEC 62368-1.
- 5. Notified body reference — only if the directive requires third-party assessment; for most wellness devices, this section is marked "Not applicable."
- 6. Signatory details — full name, job title, and legal authority to sign on behalf of the manufacturer.
- 7. Place and date — where the DoC was signed and the exact date (always after the test reports are issued).
- 8. Declaration statement — the sentence "We declare under our sole responsibility that the product to which this declaration relates is in conformity with the directives listed above."
What standards should be listed for heated massagers and light-therapy devices?
For heated massagers and light-therapy devices, the standards you list must cover electrical safety, EMC, RoHS, and photobiological safety, typically 6-9 harmonized standards in total. The exact list depends on your target market — the EU uses EN standards, the UK has the same standards under SI 2019/696, and the US relies on UL standards instead of a single DoC.
Here is how the standard matrix typically maps out for wellness devices in this category:
| Directive/Regulation | EU Standard Reference | What it covers | Required for |
|---|---|---|---|
| EMC — 2014/30/EU | EN 55014-1, EN 55014-2, EN 61000-3-2, EN 61000-3-3 | Radio emissions, immunity, harmonic current | All products with electronics |
| LVD — 2014/35/EU | EN 60335-1 (household appliances) | Electrical safety for motorized/heated devices | Products with mains power or battery + charger |
| RoHS — 2011/65/EU | EN IEC 63000 | Restricted hazardous substances in electronics | All electronics |
| Photobiological safety | EN 62471 / IEC 62471 | Eye/skin safety for LED and IR light sources | Red-light therapy and light-mood products |
| Battery transport (UN) | UN 38.3 (not an EN standard) | Lithium battery transport safety | Products with rechargeable batteries |
Note that a DoC lists standards; it does not contain the raw test data. The test report is a separate document from a lab such as TÜV, SGS, or Intertek. When LIGHT BDB prepares a DoC for your private-label product, the standards listed are the ones your product was actually tested against at one of our accredited partner labs — never standards we have not verified.
Which standards differ for the US market?
For the US market, you will need a UL or ETL safety standard instead of EN standards — typically UL 60335-2-XX for household appliances — plus FCC Part 15B for EMC. The US does not issue DoCs the way the EU does; instead, you get a UL listing or a manufacturer's FCC Supplier's Declaration of Conformity (SDoC), which is a close cousin of the EU DoC. LIGHT BDB is a UL-registered factory, which means our production lines are already audit-ready for UL-based testing of your product.
When should the DoC be signed — before or after testing?
The DoC must always be signed after all testing is complete and test reports are issued, never before, because the document declares conformity to verified results. Signing a DoC prematurely is a legal risk that can amount to a false declaration, which EU market surveillance authorities treat as a serious offense.
In practice, a typical timeline for LIGHT BDB private-label projects looks like this:
- Sample phase (7-14 days) — product samples are prepared for pre-certification testing.
- Testing phase (2-4 weeks) — samples are sent to an accredited lab for the relevant EN/UL standards.
- DoC compilation (3-7 days) — our compliance team prepares the DoC referencing the test report results.
- Final review and signature — the authorized representative signs; the document is sent to you with the test report.
This timeline is industry-typical for products in the massager and light-therapy category. Most first-time importers underestimate the testing phase, so plan for a 3-4 week certification buffer before your first shipment is ready to sail.
What are the honest trade-offs with declaring conformity?
The honest trade-off with a Declaration of Conformity is that the person who signs it carries the legal liability — and if you sign it as the brand owner, you are taking on that responsibility without full control over the manufacturing process. Most US and EU brand owners handle this by asking the factory to sign as the manufacturer of record; however, this only works if the factory is willing to stand behind the product. A factory that signs the DoC but skips real testing is putting your brand at risk.
Another trade-off: a DoC is only as good as the test report it references. A low-cost report from an uncertified lab will not survive a customs spot-check. Accredited labs cost more, but the paperwork holds up. And one honest limit to state clearly: LIGHT BDB does not hold ISO 13485, and no product from our lines is FDA approved — so we never sign a DoC that references medical-device directives. For wellness products sold as consumer appliances, that is the correct and legal position.
Finally, know that the DoC is per product model. If you have 10 SKUs, you will maintain 10 DoCs. For brand owners scaling a catalog, this paperwork is a recurring overhead — budget roughly 0.5 to 1 hour per SKU per year for keeping the documents current if a standard revision changes.
How does the DoC process work with LIGHT BDB as your ODM partner?
When you work with LIGHT BDB, the DoC process is folded into your order at no extra cost, but you must request it at the quotation stage so the testing phase is scheduled into the 4-8 week lead time from deposit to FOB Shenzhen. Our compliance team prepares the document, and you receive both the DoC and the underlying test report as a package.
Concretely, the workflow across our Shenzhen finished-product assembly base and Panyu component plant is:
- Your sales contact confirms which target markets the product must comply with (EU, UK, US).
- Our engineering team provides the test plan and confirms the accredited lab and timeline.
- Sample production ships to the lab within days of sample approval.
- The DoC template is drafted in parallel so that the moment test reports arrive, the document is signed.
- You receive a PDF package: test report + DoC + any certificates (CE, RoHS, REACH declarations).
LIGHT BDB operates under ISO 9001 and ISO 14001 systems, is a UL-registered factory, holds amfori BSCI certification, and is a Sony Green Partner — which means the documentation infrastructure around your DoC is already institutionalized, not improvised per order.
What if I change my brand name or product model?
If your brand name changes, LIGHT BDB reissues the DoC with the new brand details at no cost, since the underlying test report remains valid for the same physical product. A product model change, however, triggers a new test cycle — if the electrical specifications change, a new test report and thus a new DoC are required.
Frequently asked questions
What is a Declaration of Conformity for a product?
A Declaration of Conformity (DoC) is a legal document signed by the manufacturer or their authorized representative stating that a product meets all applicable EU or UK regulatory requirements. It lists the directives, harmonized standards, product details, and the signatory's information. Customs authorities use it to verify that a product is legally allowed onto the market.
Who signs the Declaration of Conformity?
The DoC must be signed by the manufacturer or an authorized representative established within the relevant market, such as the EU or UK. In private-label manufacturing, the factory often signs as the manufacturer of record, with the brand owner listed as the responsible party in their territory. The signatory carries legal liability for the accuracy of the declaration.
Which standards does a heated eye massager DoC need to list?
A heated eye massager DoC typically lists EMC standards under directive 2014/30/EU (EN 55014-1, EN 55014-2), the Low Voltage Directive 2014/35/EU (EN 60335-1), and RoHS under 2011/65/EU (EN IEC 63000). If the product uses LEDs, it also lists photobiological safety standard EN 62471. The exact list varies depending on test results and target market.
Do I need a separate DoC for each product model?
Yes, each product model requires its own Declaration of Conformity because the DoC references specific test reports tied to that model. If you have multiple SKUs that are the same physical product with different brand labels, they can share one DoC if the technical details are identical. Any change to electrical specifications requires a new DoC.
Is a Declaration of Conformity the same as a CE certificate?
No, a DoC is the signed declaration issued by the manufacturer, while a CE certificate is a document issued by a third-party body confirming that a test was passed. For most wellness devices, there is no mandatory third-party certificate — the DoC itself is the CE marking documentation. The test report from labs like TÜV or SGS supports the DoC but is not the same document.
How long does it take to get a Declaration of Conformity?
Getting a DoC itself takes 3-7 days once the test reports are available, since it is a document compilation and review process. The full certification cycle including lab testing typically takes 3-4 weeks for massagers and light-therapy devices. Plan this buffer into your production schedule before your first shipment.
Do US products need a Declaration of Conformity?
The US does not use the EU-style DoC. Instead, US products typically require a UL or ETL safety certification plus an FCC Supplier's Declaration of Conformity (SDoC) for EMC. A UL-registered factory like LIGHT BDB can streamline this process since the production lines are already audit-ready for UL inspections.
What happens if I ship without a Declaration of Conformity?
If you ship to the EU or UK without a valid DoC, customs can hold your shipment until you provide the documentation, and you may face storage charges at the port. In some cases, market surveillance authorities can order the destruction of non-compliant products. The DoC must be available before you dispatch your goods, not after they arrive.
Is the Declaration of Conformity expensive to obtain?
The DoC document itself is inexpensive — typically under 100 USD when prepared by your ODM partner — but the testing that supports it is the real cost. Accredited lab testing for wellness devices ranges from roughly 2,000 to 8,000 USD depending on the number of standards and the lab. Some ODM partners include the DoC free of charge when you commit to production orders, as LIGHT BDB does for ODM orders above 500 pieces.
Can I sign the DoC myself as a US brand owner?
Technically yes, but only if you have an authorized representative established in the EU or UK, and you must hold the technical documentation. Most US brand owners prefer to have the ODM factory sign as the manufacturer of record, keeping the compliance burden with the entity that controls production. This is a legal structure decision you should make with your compliance advisor.
