On May 13, 2026, U.S. Customs and Border Protection （CBP） officially launched the ‘Digital Supplier Archive’ （DSA） system. As a key implementation measure of the Import Security Acceleration Act of 2026, this system will directly affect Chinese foreign trade entities exporting to the U.S. with shipments exceeding $2500/order, and will in particular create a substantive market entry threshold for B2B export enterprises that rely on their official websites as proof of compliance. Behind this policy adjustment is an upgraded U.S. regulatory logic that shifts supply chain digital identity verification upstream to the export source itself.

Event Overview

U.S. Customs and Border Protection （CBP） officially brought the ‘Digital Supplier Archive’ （DSA） system online on May 13, 2026, as a supporting measure for the Import Security Acceleration Act of 2026. All companies exporting to the U.S. with a single shipment value exceeding $2500 must ensure that their official websites operating within China simultaneously meet two technical verification requirements: first, deployment of a valid HTTPS encryption protocol; second, completion of the ICP filing with China’s Ministry of Industry and Information Technology （MIIT） and public display of the filing number. Suppliers that fail to pass the dual verification will have their corresponding goods automatically flagged as ‘Pending Enhanced Review’ during U.S. customs clearance, resulting in an average port detention extension of 3–7 working days and triggering a manual compliance review process. This mechanism has already been connected to the customs data exchange platform of the three USMCA countries （the United States, Mexico, and Canada）, supporting real-time cross-border comparison of regulatory information.

Which Sub-Sectors Will Be Affected

Direct Trading Enterprises

Foreign trade companies that use their self-operated official websites for online order acquisition, electronic contract signing, and order fulfillment will bear the brunt. The impact is reflected as follows: if the official website has not deployed HTTPS or the ICP filing number is not prominently displayed at the bottom of the homepage, the CBP system will be unable to complete DSA registration, causing all subsequent customs declarations to fail in association; some companies have a lower-than-expected actual pass rate due to issues such as expired historical filings and inconsistencies between the domain name and the filing entity. Analysis suggests that the degree of impact on such enterprises is strongly negatively correlated with the maturity of their digital infrastructure.

Raw Material Procurement Enterprises

Enterprises engaged in agency export of bulk raw materials （such as chemicals, metal ores, and primary processed agricultural products） often declare customs under the name of a trading company, but the U.S. side is increasingly requiring the official website of the upstream factory as the basis for supply chain traceability. Observations show that when the buyer’s official website cannot pass DSA verification, CBP may extend its review to the official website of the domestic manufacturer it claims to cooperate with—which means that raw material procurement behavior itself is beginning to bear ‘digital joint liability.’

Processing and Manufacturing Enterprises

If OEM/ODM manufacturers publicly maintain official websites （especially those containing English versions, product catalogs, certification certificates, etc.）, they will be identified by the CBP system as potential ‘de facto suppliers.’ Even if they do not export directly, as long as their official websites are cited by importers in the DSA, they will be included within the scope of verification. What deserves more attention at present is that some enterprises host their official websites with overseas cloud service providers, resulting in ICP filing numbers failing to resolve properly or incomplete HTTPS certificate chains, with the rate of technical non-compliance higher than expected.

Supply Chain Service Enterprises

These include comprehensive foreign trade service enterprises （comprehensive service providers）, AEO advanced certified customs brokerage agents, and cross-border compliance consulting institutions. The impact is reflected in the restructuring of service models: the original ‘document compliance package’ needs to be upgraded to a ‘digital identity compliance package,’ covering new steps such as ICP filing status diagnostics, HTTPS certificate validity testing, and compliance auditing of the placement of filing numbers on official websites. More appropriately understood, DSA is driving third-party service providers to shift from ‘post-incident document remediation’ to ‘pre-incident digital infrastructure coordination.’

Key Points and Response Measures for Relevant Enterprises or Practitioners

Immediately Check the Basic Configuration of the Official Website

Log in to the MIIT ICP/IP Address/Domain Name Information Filing Management System to confirm whether the filing status is ‘Approved’ and whether the entity information is consistent with the exporting enterprise; use tools such as SSL Labs to test HTTPS certificate validity, key strength, and protocol compatibility, ensuring that TLS 1.2 and above are enabled.

Standardize the Public Disclosure Specifications of Official Website Information

In the fixed area at the bottom of the website homepage （not in a pop-up window, not on a redirected page）, publicly display the ICP filing number （for example: 京ICP备12345678号-1） and the public security filing number （if applicable） in crawlable HTML text form, avoiding image-based display, JS dynamic rendering, or hidden CSS styles.

Carefully Manage Multiple Domains and Subsites

After the primary domain name completes ICP filing, second-level domains （such as en.example.com） and international sites （such as example.global） do not automatically inherit the filing qualification; if they are used for U.S.-facing business display, they must either complete filing separately or be redirected via 301 to the filed primary domain, otherwise the DSA system will regard them as independently unf​​iled sites.

Establish a DSA Compliance Response Mechanism

It is recommended that enterprises designate dedicated personnel to handle CBP DSA Portal account registration and updates, and regularly export verification logs; for orders marked as ‘Pending Verification,’ reserve at least a 5 working day buffer period to initiate technical rectification, so as to avoid affecting shipping schedules and documentary credit transaction milestones.

Editorial Viewpoint / Industry Observation

Observably, DSA is not an isolated technical upgrade, but rather a strategic pivot through which the U.S. embeds ‘trusted digital identity’ into the global supply chain governance framework. Analysis shows that its real impact lies not in blocking shipments, but in accelerating the consolidation of digitally mature exporters——if SMEs continue to rely on third-party platforms （such as Alibaba International Station） for redirection-based transactions while neglecting the infrastructure of their own official websites, they will develop a structural disadvantage in customer trust, compliance response speed, and long-term pricing power. The shift signals a de facto ‘digital gatekeeping’ layer now sitting alongside traditional customs controls.

Conclusion

The implementation of the DSA system marks export compliance moving from the stage of ‘document compliance’ to that of ‘digital identity compliance.’ This is not a one-time policy adaptation task, but a pressure-driven shift requiring Chinese enterprises to enhance their governance capabilities over official websites as core digital assets. Rational observation suggests that its long-term significance lies in pushing the export ecosystem from being ‘channel-driven’ to ‘trust-driven’; enterprises that truly possess sustainable global expansion capabilities must first become verifiable, traceable, and trustworthy digital entities.
