DSA Expands to B2B Platforms; Multilingual Independent Websites Must Disclose Their Recommendation Algorithms

On June 30, 2026, new and explicit changes emerged regarding the scope of application of the EU Digital Services Act (DSA). According to information released by the European Commission that evening, starting from October 2026, B2B independent websites that provide product catalogs, inquiry matching, or supplier recommendation services to EU business buyers will be brought within the scope of the relevant requirements. For companies that rely heavily on cross-border customer acquisition, online procurement matching, supplier display, and recommendation mechanisms, this change deserves attention, because website display logic, explanations of data use, and arrangements for human intervention are shifting from operational issues to compliance matters that require public disclosure.

What Has Been Clarified by This Rule Change

Confirmed information shows that the European Commission announced on the evening of June 30, 2026 that, starting from October 2026, the scope of application of the DSA will officially cover B2B independent websites that provide product catalogs, inquiry matching, or supplier recommendation services to EU business buyers.

According to the requirements already provided, relevant websites need to disclose, on their "About Us" or "Compliance Center" pages and in the local language, the basic logic of recommendation algorithms, the scope of data use, and the human intervention mechanism.

The confirmed penalty information states that violations of the above requirements may result in a fine of up to 6% of global revenue.

What Is Affected Is Not Just Website Pages, but the Entire Online Transaction Chain

Operators of Independent Websites Targeting EU Business Buyers

These entities are affected most directly, because their websites themselves are where the rules apply. Any business that provides product catalog display, inquiry matching, or supplier recommendation services to EU business buyers needs to pay attention to whether page disclosures are complete, whether language versions are properly matched, and whether explanations of recommendation mechanisms can be presented consistently to external parties. From an analytical perspective, the impact is mainly concentrated on website compliance design, content review, data explanation standards, and alignment with internal operational processes.

Exporters and Manufacturers That Rely on Platforms for Customer Acquisition

For exporters and processing manufacturers that acquire business customers through multilingual independent websites, although this change first affects the website operation side, it may subsequently be transmitted to customer acquisition and inquiry distribution processes. Based on observation, if recommendation logic, the scope of data use, and human intervention mechanisms need to be made public, companies also need to review their actual practices in product display, supplier ranking, inquiry allocation, and other processes at the same time, so as to avoid inconsistencies between front-end statements and back-end execution.

Buyers and Supply Chain Service Participants

For buyers, supply chain service companies, and relevant participants that perform matching functions, what deserves attention is not simply the addition of a page explanation, but the possible adjustment of online screening, comparison, and inquiry circulation methods after the transparency of recommendation mechanisms is increased. From an analytical perspective, such changes may affect the paths through which procurement information reaches users, the ways suppliers gain exposure, and the focus of reviews of website compliance capabilities, especially during the pre-cooperation qualification verification and service terms confirmation stages.

Service Providers Offering Compliance, Content, and Technical Support

Organizations that provide services such as website building, content localization, compliance review, and technical maintenance will also be indirectly affected. The reason is that clients may be more likely in the future to require algorithm explanations, disclosure pages, and multilingual content management to be included in the delivery scope. What currently deserves closer attention is whether the relevant services can cover local-language disclosures, page update traceability, and consistency in external explanations of human intervention mechanisms.

Which Practical Issues Companies Need to Watch More Closely Now

First Confirm Whether the Business Falls Within the Scope of Application

Companies first need to verify whether their independent websites target EU business buyers and whether they provide services such as product catalogs, inquiry matching, or supplier recommendations. From an analytical perspective, this step determines the priority of subsequent disclosures, reviews, and internal coordination, and should serve as the starting point for compliance checks.

Align Public Explanations with Back-End Mechanisms

The confirmed requirements emphasize the disclosure of the basic logic of recommendation algorithms, the scope of data use, and human intervention mechanisms. For companies, the current focus should be whether the statements on public pages can truly correspond to actual operational processes, including how the basis for recommendations is summarized, what types of data are used within the relevant scope, and whether humans intervene in ranking or distribution. This is an issue of alignment between compliance expression and business execution, and cannot remain only at the copywriting level.

Pay Attention to the Consistency of Local-Language Versions

Because the requirements explicitly call for disclosure in the local language, companies need to pay attention, in the management of multilingual independent websites, to whether pages in different languages are updated synchronously, whether terminology is consistent, and whether deviations occur in core statements. Based on observation, this is related not only to page completeness, but also to consistency in external explanations at a later stage.

Continuously Follow Up on Implementation Standards and Customer Review Requirements

What is currently known includes the scope of application, timeline, disclosure location, disclosed content, and maximum penalty, but more detailed implementation standards were not provided in the input information. A more appropriate interpretation is that companies should, at this stage, prepare in advance for website reviews, internal process sorting, and external explanatory materials, while continuing to monitor possible subsequent official statements, customer compliance questionnaires, tender documents, or new requirements in cooperation terms.

From an Industry Perspective, This Looks More Like a Clear Implementation Signal

Based on observation, the core of this information does not lie in a general discussion of digital regulation, but in the explicit inclusion of B2B independent websites in the rule scenario for EU business buyers. For companies that have long regarded multilingual websites as marketing and inquiry tools, the obligation to explain recommendation mechanisms is becoming more specific. From an analytical perspective, this looks more like a signal that the boundaries of rule application are being implemented, rather than a reminder that remains at the level of principle.

At the same time, judgment should remain restrained. The input information did not provide more detailed implementation rules, review methods, or industry feedback, so the subsequent impact cannot yet be described as a unified result that has already occurred. What is more worth continuously observing is how market participants will incorporate this requirement into internal reviews, cooperation access, and daily operational processes.

The Practical Significance for the Industry Is First Reflected in Front-Loaded Compliance

Overall, this change has already brought the recommendation and matching mechanisms of some B2B independent websites under clearer public compliance requirements. It affects not a single page, but the consistency of website display, explanations of data use, internal human intervention processes, and external cooperation explanations.

At present, a more appropriate way to understand this information is to regard it as a rule change with a clearly defined timeline and basic requirements, while continuing to observe subsequent implementation standards, customer responses, and industry feedback. For relevant companies, the short-term priority is not to overextend the interpretation, but to confirm business boundaries as soon as possible, sort out page disclosure content, and check the actual implementation status of multilingual websites.
