WuXi AppTec’s 1260H Listing Brings the BIOSECURE Act Back to Center Stage
On June 8, 2026, the Department of Defense published its updated list of “Chinese military companies” under Section 1260H of the National Defense Authorization Act for Fiscal Year 2021. Among the entities newly added: WuXi AppTec Co., Ltd., the China-based contract development and manufacturing organization (CDMO) whose name has been at the center of the BIOSECURE Act debate since 2024. The designation, set out in a Federal Register notice scheduled for publication on June 10, 2026, states that WuXi AppTec “is indirectly owned by [the State-Owned Assets Supervision and Administration Commission of the State Council] and is indirectly affiliated with [State Administration of Science, Technology and Industry for National Defense] and the [People’s Liberation Army].”
The inclusion of WuXi AppTec on the 1260H list triggers one of the two statutory pathways to “biotechnology company of concern” (BCOC) status under the BIOSECURE Act—a law that, when fully implemented, will prohibit federal agencies from contracting with or funding companies that use a BCOC’s biotechnology equipment or services. This is a significant development for the life sciences industry, even though its most consequential effects remain months—possibly years—away.
Background: From Named Entity to 1260H Pathway
Industry observers will recall that earlier iterations of the BIOSECURE Act—including the version that passed the House in 2024—expressly named WuXi AppTec, WuXi Biologics, BGI, MGI, and Complete Genomics as biotechnology companies of concern. That named-entity approach was a major source of industry pushback, particularly with respect to WuXi, given its outsize role as a CDMO to U.S. biopharmaceutical companies.
When the BIOSECURE Act was signed into law on December 18, 2025 as part of the FY2026 NDAA, the named-entity list was gone. Instead, the enacted statute establishes two mechanisms by which a company can be deemed a BCOC:
- 1260H Pathway: An entity that appears on DoD’s annual Section 1260H list of “Chinese military companies” and is involved in the manufacturing, distribution, provision, or procurement of biotechnology equipment or services.
- OMB Pathway: The Office of Management and Budget may publish a separate list of additional BCOCs meeting statutory criteria related to foreign adversary control and national security risk. OMB can also designate subsidiaries, parents, affiliates, or successors.
At the time of enactment, the 1260H list included BGI and MGI but did not include WuXi AppTec or WuXi Biologics. As we and others noted at the time, this represented a limited win for the industry—but with the clear caveat that WuXi could be added in a subsequent 1260H update. That scenario has now materialized.
What Does This Mean in Practice?
The 1260H listing carries both immediate effects on DoD contracting and downstream BIOSECURE Act implications.
Immediate effect: 1260H designation. As of publication of the Federal Register notice, WuXi AppTec is a designated “Chinese military company” for purposes of Section 1260H. This designation carries its own DoD contracting restrictions and reputational consequences, but it does not, by itself, impose the broader procurement prohibitions of the BIOSECURE Act.
Downstream effect: BIOSECURE Act prohibitions. Because WuXi AppTec is now on the 1260H list, it will satisfy the statutory criteria for BCOC status once OMB establishes and implements a process to make a finding that WuXi AppTec is involved in providing biotechnology equipment or services (which it almost certainly will). However, the Act’s prohibitions do not take effect for 1260H BCOCs until 60 days after the FAR Council revises the Federal Acquisition Regulation to implement them. Under the statutory timeline, OMB must publish its BCOC list by December 2026, issue implementing guidance within 180 days, and the FAR Council then has one year to revise the FAR. If the government uses all allotted time, it could be nearly three years before the Act takes effect.
Scope: Federal Contracts and Exclusions
A note of caution on scope: the BIOSECURE Act’s prohibitions apply only where there is a nexus to federal procurement, grants, or loans. Specifically, federal agencies are prohibited from (1) procuring biotechnology equipment or services from a BCOC, (2) entering into contracts with entities that use a BCOC’s equipment or services to perform the federal contract (including through subcontractors), or (3) making loans or grants for the purpose of procuring such equipment or services. The Act applies to contracts subject to the FAR. Critically, Medicare and Medicaid agreements are not contracts subject to the FAR and are therefore excluded from the scope of the Act’s prohibitions.
Five-Year Grandfathering Period
The Act includes a five-year grandfathering period for contracts (or contract options) that are in place before the effective date of the BIOSECURE prohibitions with respect to a given BCOC. The five-year clock runs from the date the FAR is revised. During this period, the Act’s prohibitions do not apply to those pre-existing contractual arrangements.
For companies currently engaged with WuXi AppTec under federal contracts or funding mechanisms, this means existing arrangements are not immediately at risk. Companies should be evaluating the duration of their existing contractual commitments, assessing whether services will extend beyond the five-year grandfathering window, and closely watching WuXi’s request for reconsideration or other appeals to be removed from the list to determine whether alternative suppliers will be needed. Depending on the services WuXi provides, tech transfer runways can be long and expensive.
Reconsideration and WuXi’s Response
Entities added to the 1260H list are not without recourse. The Federal Register notice outlines a formal reconsideration process whereby listed entities can argue that they do not meet the criteria for inclusion on the list.
WuXi AppTec has already signaled its intent to pursue that avenue. In a public statement issued on June 8, 2026, the company characterized the designation as “mistaken and baseless,” stating that it is “an independent, publicly traded company” and denying any ownership, control, or affiliation with any government or military organization. WuXi AppTec stated it “will pursue all available remedies to correct this designation,” although the outcome of any reconsideration request is uncertain.
Looking Ahead
We expect significant interest from trade groups and industry stakeholders, as well as continued congressional discussion. The House Select Committee on the Chinese Communist Party issued a statement on June 8 characterizing the updated 1260H list as “a warning to American businesses” and referencing the bipartisan BIOSECURE Act.
We will continue to monitor developments, including OMB’s publication of the formal BCOC list (due no later than December 2026), any reconsideration proceedings, and the FAR rulemaking process. If you have any questions about what this means for your business, do not hesitate to reach out.
