TL;DR: Recent U.S. and Chinese trade restrictions are unlikely to restart the 2025 trade war, according to ZeroFox, but they point to a longer-term strategy of reducing mutual dependence through narrower controls, supply-chain mapping, and pressure on critical inputs rather than broad escalation.
At a glance
What this is: ZeroFox's forecast says recent U.S. and China trade restrictions are calibrated to preserve the 2025 truce while signalling a longer-term push to reduce dependence on each other.
Why it matters: For IAM and NHI practitioners, the relevance is indirect but real: supply chain decoupling changes third-party exposure, procurement scrutiny, and the resilience assumptions behind outsourced technology and services.
Context
The core issue is not a single tariff or export control, but a widening governance gap between short-term truce management and long-term strategic decoupling. Governments are increasingly targeting inputs, suppliers, and transit paths rather than only end products, which makes dependency mapping more important than simple country-of-origin checks.
That matters to security teams because supply chain risk now extends beyond vendors you already know to the lower-tier actors, materials, and service dependencies that support them. In identity programmes, the parallel is third-party access governance: the weakest control often sits several layers away from the visible system boundary.
Key questions
Q: How should organisations govern third-party risk when suppliers depend on other suppliers?
A: Organisations should treat third-party risk as a chain, not a single contract. The key is to understand where concentration, substitution difficulty, and ownership issues sit several tiers down. That requires broader inventory, recurring assurance, and escalation paths when a lower-tier dependency can affect production, data handling, or service continuity.
Q: Why do concentrated supply chains create resilience risk even when direct vendors look stable?
A: Because direct vendor stability does not remove dependency on scarce inputs, limited manufacturing capacity, or politically exposed routes. A supplier can remain operational while still being unable to absorb shocks or reroute production quickly. The risk is hidden in the absence of alternatives, not just in vendor failure.
Q: What are the signs that a supply chain dependency is too concentrated?
A: Warning signs include repeated use of the same upstream source, few qualified substitutes, long requalification cycles, and business processes that cannot tolerate even short interruptions. If a dependency would require months to replace, it is already a resilience issue, even if no incident has occurred.
A: Yes. Trade restrictions often reveal hidden concentration risk, and they can change the economics or legality of sourcing overnight. Security and procurement should re-evaluate critical suppliers together, because continuity, compliance, and trust all depend on the same upstream realities.
Technical breakdown
Why lower-tier supplier visibility matters more than country filters
Trade restrictions that focus on finished goods can be routed around, but controls aimed at raw materials, component inputs, and subcontractors are harder to evade. That shifts the defensive problem from screening a direct supplier list to tracing the full chain of dependency. In security terms, this is the difference between managing a declared vendor and understanding the trust extended through its own providers, systems, and services. The article's emphasis on lower-tier suppliers shows why governance models that stop at the first tier routinely miss the real exposure surface. See the TPRM and Security Ratings Buyer's Guide.
Practical implication: Map the full supplier chain, not just the contracted vendor, before you assume a dependency is controlled.
How decoupling changes resilience assumptions in critical technology programmes
When states target inputs such as rare earths, polysilicon, drones, and advanced robotics, the issue is not only cost. It is continuity of production, substitution speed, and the ability to absorb shocks without breaking downstream delivery. For security and resilience programmes, that means third-party continuity planning must account for source concentration, geographic routing, and the practical time needed to requalify alternative suppliers. Dependency concentration becomes a resilience control problem, not just a procurement issue.
Practical implication: Build fallback options for concentrated dependencies before a geopolitical event turns them into delivery failures.
Why procurement controls increasingly overlap with security governance
The article shows a clear shift toward screening suppliers and subcontractors for financial, manufacturing, and foreign influence risk. That is not traditional procurement alone. It is a governance model that blends due diligence, sanctions awareness, operational resilience, and ongoing assurance. For identity and access programmes, the parallel is obvious: trust decisions cannot live only at onboarding. They need lifecycle review, exception handling, and offboarding, especially where third parties can influence systems, data, or production workflows. See the Authorisation Models Guide.
Practical implication: Treat supplier onboarding as the start of governance, not the end of it.
NHI Mgmt Group analysis
Dependency governance is becoming a control discipline, not a sourcing preference. The article shows governments moving from broad tariffs to narrower interventions that target inputs, transit routes, and lower-tier suppliers. That pattern matters because it rewards organisations that can see beyond direct contracts and understand where operational dependence really sits. For identity and access programmes, the lesson is familiar: the visible relationship is not always the risky one. Practitioners should govern dependency chains the way they govern privileged access paths.
Supply chain resilience now depends on knowing where substitution is impossible. The forecast points to rare earths, polysilicon, drones, and advanced robotics as categories where concentration risk shapes policy. Those same dynamics appear in security programmes when a single supplier, platform, or service tier becomes too embedded to replace quickly. The practical question is no longer whether a dependency exists, but how fast the organisation can re-route around it without breaking operations.
Third-party exposure is a lifecycle problem: the article's emphasis on lower-tier suppliers mirrors a governance failure seen in identity programmes, where control often stops at the first relationship instead of the full chain. Supplier and third-party review is relevant here because the real risk is hidden in nested dependencies, not just in the top-level contract. Practitioners should extend assurance to subcontractors, resellers, and service intermediation layers.
Geopolitical decoupling is likely to increase assurance pressure on technology ecosystems. When trade policy begins to scrutinise inputs, ownership, and routing, security teams should expect more questions about provenance, continuity, and substitution. That will not only affect supply chain teams. It will also change how identity, access, and platform governance teams justify trust in externally sourced services. The organisations that already map dependency depth will adapt faster.
What this signals
Concentrated dependency is now a governance signal, not just a supply chain metric. The article suggests organisations should watch for suppliers that cannot be replaced quickly because of scarce inputs, single-country manufacturing, or nested subcontractors. That is the point where resilience planning, procurement review, and security assurance converge.
For identity programmes, this is the same structural lesson as third-party access governance: the risk is rarely in the visible edge relationship alone. Teams should expect more pressure to evidence who the upstream actors are, how often they are reviewed, and how quickly the organisation can shift if a dependency becomes unusable.
Dependency depth: the real control question is how far into the chain an organisation can see before trust becomes assumption. As trade policy increasingly targets inputs and routes, practitioners should assume that hidden dependencies will be tested first.
For practitioners
- Map lower-tier supplier dependencies Extend risk mapping beyond direct vendors to subcontractors, manufacturers, logistics paths, and upstream inputs that can affect service continuity. See the TPRM and Security Ratings Buyer's Guide.
- Add geopolitical triggers to supplier reviews Define review events for sanctions, export controls, tariff shifts, and ownership changes so that supplier risk is reassessed before disruption spreads.
- Identify concentrated technology inputs Flag single-source dependencies for critical materials, components, and service providers where substitution would take months rather than days.
- Separate onboarding from assurance Move beyond one-time due diligence by scheduling recurring reviews of third-party access, sourcing, and operational resilience assumptions.
Key takeaways
- The article frames trade restrictions as a signal of deeper decoupling, where governments are trying to manage strategic dependence rather than simply tax imports.
- For security and identity practitioners, the transferable lesson is that nested dependencies create blind spots, especially when assurance stops at the first supplier relationship.
- Programmes that map lower-tier exposure and revisit it regularly will be better positioned when geopolitical or commercial shocks force rapid substitution.

Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST CSF 2.0 provides the primary governance reference for this term.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | ID.SC-01 — Supply Chain Risk Management Strategy | The article centres on mapping and managing lower-tier supplier dependency risk. |
| ID.SC-03 — Supply Chain Dependencies and Critical Suppliers | The report repeatedly focuses on concentrated suppliers and upstream dependencies. | |
| ID.SC-04 — Supply Chain Partners Are Assessed and Monitored | The article stresses recurring review of foreign ownership, controls, and ongoing exposure. | |
| Recommendation — Map critical suppliers and subcontractors to ID.SC-01 so dependency depth is visible before disruptions hit. Identify critical suppliers and test substitution options for the dependencies that cannot be quickly replaced. Reassess supplier risk on a schedule and after policy shifts that change sourcing or routing. | ||
Key terms
- Supply Chain Concentration Risk: The exposure created when an organisation depends on a small number of sources for critical materials, components, or services. If one source becomes unavailable or restricted, continuity can fail quickly because substitutes are slow, expensive, or politically constrained.
- Lower-Tier Supplier: A supplier that sits beneath a direct contractual vendor in the wider production or service chain. These parties often create the real operational risk because they can control raw materials, manufacturing steps, data handling, or delivery routes that the top-level contract does not reveal.
- Dependency Mapping: Dependency mapping is the process of identifying which systems, services, and workflows rely on a given identity or secret. It is critical for NHI rotation because teams need to know what will fail before they change credentials. Without it, security teams often delay remediation to avoid outages.
- Third-Party Assurance: Third-party assurance is the process of validating that suppliers and partners meet an organisation’s required security controls. It is more than contract language, because it needs evidence, monitoring and offboarding discipline to ensure external access and integrations do not become uncontrolled risk paths.
