NST maintains documented transparency across its ownership structure, governance framework, and decision-making processes that meet FEOC requirements. This transparency supports customer due diligence, regulatory audits, and reliable solar compliance.
- Legal Position Under US FEOC Framework
NST has obtained a formal legal opinion from a US law firm concluding that, based on its current ownership and governance structure, NST should not be considered a Prohibited Foreign Entity under Section 7701(a)(51) of the Internal Revenue Code.
This opinion supports alignment with applicable IRA and related US supply chain requirements.
Supply Chain & Traceability
We implement end-to-end traceability across key stages of our supply chain, including raw material sourcing, manufacturing operations, and product flow. The traceability controls are structured to support customer verification, regulatory review, and detailed assessment of material origin and supply chain integrity.
