Frequently Asked Sourcing Questions
How do you charge for your sourcing services?
We offer flexible pricing options: a transparent commission model (typically 3%-8% depending on order volume) or flat project-based fees for individual factory audits and quality inspections. No hidden fees or kickbacks.
Can I use my existing suppliers and just hire you for QC & logistics?
Absolutely. Many of our clients have pre-existing factory relationships in China and engage Topsourcingco strictly for factory audits, ongoing production tracking, Pre-Shipment Inspection (PSI), and cargo consolidation.
How do you protect my intellectual property (IP) & designs?
We execute legally binding China-compliant NNN (Non-disclosure, Non-use, Non-circumvention) agreements with manufacturing partners prior to releasing technical CAD drawings or proprietary tooling specs.
What happens if defective products are found during inspection?
If defects exceed agreed AQL limits, we immediately issue an inspection alert, hold final balance payments, and manage factory rework or component replacements on-site before cargo is cleared for export.
