FCC restrictions are forward-looking, but compliance and customer substitution will create long-term structural constraints

Overview

This report discusses the impact of U.S. FCC-related market-access measures on Chinese inverter and robotics companies. Based on seven U.S. market-access actions over the past eight years, Nomura concludes that the policy direction is persistent and that the implementation pace is primarily determined by replacement costs and supply tightness.

Core views

The report argues that U.S. policy has two main lines: raising costs for mid- and low-end imported products while reducing supply-chain dependence; and limiting China's rapid catch-up in high-end technology products to preserve generational gaps. Inverters are mainly affected by the former. In the near term, this does not imply a comprehensive exit from the U.S. market, but rather constraints on new models, higher compliance spending, and customer-substitution risk. Robotics and other technology subsectors may be exposed to both policy frameworks, resulting in higher long-term risk.

Analysis framework

By reviewing cases involving Kaspersky, Chinese telecom operators' licenses, Huawei and ZTE telecommunications equipment, Hikvision, and drone rules, the report compares availability of substitutes, replacement costs for installed equipment, and changes in regulatory scope to infer the impact pathway of FCC rules on Chinese companies.

Methodology notes

• Policy scenario analysisMarket-access case comparison

  Using historical regulatory cases to identify policy direction and implementation sequence

  The report compares cases by replacement costs, supply tightness, and the difficulty of replacing installed assets, concluding that regulation often first restricts new models, then tightens existing approved products, and only lastly addresses deployed equipment.

• Supply-chain risk analysisHBOM/SBOM compliance assessment

  Hardware and software bills-of-materials disclosure

  Companies need to address compliance requirements including hardware and software bills-of-materials disclosures, software and data localization, component re-sourcing, and conditional-approval documentation; disclosures may also make supply chains subject to subsequent regulatory identification.

• Sungrow (300274 CH)

  A Chinese inverter company affected by U.S. FCC market-access and supply-chain compliance requirements

  Strengths

  Existing approved models may still be imported under the rules described in the report, so this does not imply a comprehensive exit from the U.S. market in the near term.

  Weaknesses

  The new-model pipeline may be frozen; the company must bear costs for component re-sourcing, software and data localization, HBOM/SBOM disclosures, and conditional-approval documentation.

  Comparison

  Compared with readily substitutable software or licensing products, inverter-related restrictions are more likely to proceed gradually due to replacement and supply constraints; compared with high-end technology products, they are mainly affected by the policy line of raising costs and reducing supply-chain dependence.

  Risks

  Customers certifying second suppliers, long-term share loss, expansion of regulatory scope, and subsequent targeted regulation triggered by supply-chain disclosures.

• Chinese robotics and high-end technology companies

  May be affected simultaneously by market-access restrictions and technology-generation constraints

  Strengths

  The report provides no evidence of strengths at the individual-company level.

  Weaknesses

  Their high-end technology characteristics may make them priority targets for restrictions intended to limit China's rapid catch-up.

  Comparison

  Compared with inverters, these companies are more likely to fall under both policy frameworks: raising compliance costs and maintaining technology-generation gaps.

  Risks

  Restricted access for new products, impeded technology access, and heightened supply-chain and customer risks.

Key data

• U.S. market-access actionsSeven over eight yearsThe report uses this to conclude that the policy direction is persistent.
• Approved funding for Huawei and ZTE rural-network replacement compensationUS$4.98 billionInitial funding covered only 39.5%; the U.S. Congress subsequently added approximately US$3.08 billion.
• Progress of rural-network replacementApproximately 42%As stated in the FCC's eighth report to Congress in June 2026.
• FCC July 28 actionDA 26-786The report believes it mainly covers new equipment models, while existing approved models may still be imported.
• Sungrow ratingNeutralThe report does not provide a target price, current price, or expected upside/downside.

Impact & implications

For Chinese inverter companies such as Sungrow, the policy impact is more likely to manifest as higher costs and operational complexity rather than an immediate loss of the U.S. market. If customers accelerate onboarding second suppliers to reduce compliance uncertainty, long-term market share and customer stickiness may come under pressure. For robotics and technology products with higher technological content, market-access restrictions and technology-generation constraints may compound each other.

Risks

• The U.S. FCC or other regulators may expand the scope of the rules.
• Approvals and sales cadence for new models may be constrained.
• Compliance, supply-chain restructuring, and localization investments may exceed expectations.
• HBOM/SBOM disclosures increase the risk of supply chains being identified and subject to subsequent regulation.
• U.S. customers may onboard second suppliers, resulting in declining long-term market share.
• Uncertainty remains regarding the pace of policy implementation and final detailed rules.

What to watch

• The scope of subsequent FCC rules and whether they extend from new models to existing approved products.
• New FNPRMs and their treatment of gaps remaining from the July Covered List.
• Progress in U.S. customer second-supplier certification and changes in procurement strategies.
• Whether companies' capacity layouts outside the United States can meet compliance requirements such as “Buy American.”
• The cost and progress of component restructuring, software and data localization, and HBOM/SBOM disclosures.
• The pace of U.S. efforts to replace deployed equipment and implement compensation arrangements.
