On April 24, 2026, Guangzhou Jujiexin Technology's 2026 anti-overloading dedicated quartz sensor obtained EU WELMEC 7.2 certification for "Weighing Systems for Moving Road Vehicles". This is the first domestically produced quartz dynamic weighing sensor in China to meet this standard, and relevant enterprises in niche fields such as intelligent transportation, road law enforcement, weighing equipment integration, and cross-border trade should pay close attention to the substantive changes it may bring to technical market access, project bidding, and supply chain adaptation.

Event Overview

On April 24, 2026, Guangzhou Jujiexin Technology's 2026 anti-overloading dedicated quartz sensor officially passed the EU WELMEC 7.2 certification for "Weighing Systems for Moving Road Vehicles". This certification was issued by WELMEC (the European Cooperation in Legal Metrology) and is mandatorily recognized by transportation authorities in Germany, the Netherlands, Sweden, and other countries. The certification result means that the product can be exempted from repeated type approval in the above countries and can directly enter the shortlist for local intelligent transportation project tenders.

Which Sub-sectors Will Be Affected

Direct Trading Enterprises

As WELMEC 7.2 certification carries mandatory recognition effect in multiple countries, trading enterprises engaged in the export of dynamic weighing equipment will face a structural reduction in bidding barriers: there will be no need to separately apply for type approval for the same product in Germany, the Netherlands, Sweden, and other countries, and compliance costs and timelines are expected to be reduced. The impact is mainly reflected in improved bidding response efficiency, simplified preparation of qualification documents, and accelerated expansion into regional markets.

Processing and Manufacturing Enterprises

If domestic manufacturers of dynamic weighing sensors have not yet obtained WELMEC 7.2 certification, their products will be at a qualification disadvantage when participating in European intelligent transportation infrastructure projects. The impact is mainly reflected in restricted eligibility for international tender shortlisting, a shift in procurement preference among system integrators, and increased pressure for subsequent certification investment.

Channel Distribution Enterprises

Distributors of weighing equipment and system integration service providers targeting the European market need to reassess the compliance status of their existing represented products. The impact is mainly reflected in the fact that some uncertified products may be required by end users to be replaced or supplemented with certification materials; in quotations for new projects, certification applicability must be clearly indicated, otherwise there may be performance risks.

Supply Chain Service Enterprises

Third-party institutions providing CE certification consulting, type testing coordination, and EU transportation regulation adaptation services will face incremental demand from domestic sensor manufacturers. The impact is mainly reflected in the fact that specialized WELMEC 7.2 service capability will become a point of differentiated competition, and workloads will increase in areas such as translation of technical documents, coordination of test plans, and regulatory communication support.

What Key Points Should Relevant Enterprises or Practitioners Focus On, and How Should They Respond at Present

Monitor Follow-up Official Statements or Policy Changes

At present, continuous tracking should be maintained on whether the WELMEC official website and national metrology institutes such as Germany's PTB and the Netherlands' NMI update the implementation guidelines or supplementary explanations for WELMEC 7.2, especially whether the interpretation of applicability to the "quartz sensor" category is expanded to other structural forms.

Focus on Changes in Key Product Categories, Key Markets, or Key Business Links

Priority should be given to reviewing whether your own products belong to the core sensing units within the scope of "weighing systems for moving road vehicles"; at the same time, screen whether contracted or prospective European customers come from subordinate units of transportation departments in Germany, the Netherlands, and Sweden or their designated contractors, as such customers have the most rigid requirements for certification compliance.

Differentiate Between Policy Signals and Actual Business Implementation

It should be noted that obtaining WELMEC 7.2 certification does not mean automatic winning of bids; it only resolves the issue of access qualification. Enterprises still need to submit technical proposals according to each country's bidding procedures, complete localized installation verification, and meet practical requirements such as data interface compatibility (e.g. ETCS/ITS-G5).

Prepare Procurement, Supply Chain, Communication, or Contingency Plans in Advance

For manufacturing enterprises planning to export similar products, it is recommended to launch internal compliance benchmarking——carry out gap analysis against the provisions in Appendix B of WELMEC 7.2 regarding environmental adaptability, long-term stability, anti-interference capability, and other items, and communicate in advance with qualified laboratories on testing schedules to avoid cycle delays caused by concentrated applications.

Editor's Viewpoint / Industry Observation

From an observation perspective, this certification breakthrough is more like a key signal rather than an immediately effective market outcome: it marks the first institutional alignment of domestically produced quartz sensors with the EU legal metrology system in the niche technical track of high-precision dynamic weighing. From an industry perspective, this is not simply a product upgrade event, but a phased sign of domestic enterprises proactively moving closer to mainstream international technical rules at the sensing layer of transportation infrastructure. What is more worth attention at present is whether this certification can drive downstream system integrators to accelerate the inclusion of domestic sensors in their standard BOM lists for European projects, and whether it will trigger a de facto reference effect in other EU member states (such as France and Austria) in scenarios where mandatory recognition does not apply.

Conclusion
Guangzhou Jujie quartz sensor's passing of WELMEC 7.2 certification is a substantive breakthrough for domestically produced dynamic weighing sensor components at the level of international legal metrology recognition. However, its industry significance should not be overestimated as "fully opening the European market"; it is more appropriately understood as the formation of a reusable compliance pathway under a specific technical route (quartz type), a specific application scenario (anti-overloading dynamic weighing), and a specific market access mechanism (WELMEC multi-country mutual recognition). Industry participants should pragmatically regard it as an important reference for building technical compliance capability, rather than a certain variable for short-term business growth.
