Author:GIG      Postdate:2025-05-23

In modern electronic product manufacturing, RoHS (Restriction of Hazardous Substances) testing is becoming increasingly important, especially for companies planning to enter the EU market. RoHS testing not only pertains to environmental compliance but also directly impacts a company’s market competitiveness and brand image. Today, the editor from Huabiao Testing shares insights on what RoHS testing entails and how to obtain RoHS certification for 3D printers.


RoHS Testing



What is RoHS Testing?

RoHS is a regulation introduced by the European Union to restrict the use of hazardous substances in electronic products. It encompasses the 2011 version and its 2015 amendment. The regulation applies to various electronic products, including 3D printers. RoHS restricts 10 hazardous substances, such as lead, mercury, and cadmium, prohibiting their use in electronic products to ensure safety for both humans and the environment. If you plan to sell 3D printers in the EU, RoHS certification is mandatory, and it is also significant in many other countries.


How to Obtain RoHS Certification for 3D Printers?

  1. Consultation and Preparation: Contact a professional testing agency, such as Ningbo Huabiao Testing Co., Ltd., and submit the 3D printer’s product specifications, Bill of Materials (BOM), samples, and target market information (primarily the EU).

  2. Sample Testing: The testing agency will use equipment such as XRF (X-ray Fluorescence Spectrometer) and ICP-MS (Inductively Coupled Plasma Mass Spectrometry) to test for hazardous substances. The process typically takes 5–15 working days, depending on the product’s complexity and the number of components.

  3. Results Review: After testing, the company receives a RoHS compliance report. If non-compliance is found, materials or suppliers must be adjusted, and retesting is required.

  4. Technical Documentation: Prepare RoHS technical documentation, including the test report, material declarations, and a Declaration of Conformity (DoC), for EU market access or customer audits.

  5. Market Access: Submit the RoHS compliance report and technical documentation to meet the requirements of the EU market or other regions, as well as importers or e-commerce platforms (e.g., Amazon).
