China Sourcing & NNN Agreements | OEM/ODM & Supplier Verification

China sourcing is not just about finding a factory. It is about verifying who you are dealing with, protecting your product designs, and making sure your requirements are properly understood and executed. I am a China-based sourcing and supplier verification specialist helping international businesses work more safely and efficiently with Chinese manufacturers. My work covers manufacturer sourcing, supplier due diligence, OEM/ODM coordination, product development support, technical communication, and China-focused commercial agreement documentation. China Supplier Verification and Sourcing I help overseas clients identify suitable manufacturers, verify Chinese legal entities, review business licenses and company information, compare supplier capabilities, and communicate with factories regarding pricing, MOQ, samples, production requirements, and delivery schedules. NNN Agreements and Manufacturing Protection I assist with preparing and revising bilingual English/Chinese NNN agreements and manufacturing protection documents for China-related projects. My work focuses on practical issues such as confidentiality, non-use, non-circumvention, intellectual property protection, tooling and mold ownership, unauthorized production and sales, subcontracting restrictions, liquidated damages, and proper execution by Chinese legal entities. When formal legal review is needed, I can coordinate an independent review by a licensed PRC lawyer. Technical Hardware and OEM/ODM Projects I also work on technical sourcing projects involving wearable cameras, AI glasses, embedded camera systems, PCBA solutions, SDK integration requirements, and electronic hardware manufacturing. My experience includes technical supplier screening, product specification comparisons, development feasibility discussions, prototype coordination, and factory communication. How I Work I prefer fixed-price, milestone-based projects with clearly defined deliverables and review points. This allows clients to understand the project scope, expected results, and costs before proceeding. I provide clear written communication, organized documentation, and practical recommendations based on actual supplier information. Whether you need to protect your product before contacting Chinese factories, verify a potential manufacturer, or coordinate an OEM/ODM development project, I can help you move forward with greater confidence.
