Quality Control & Inspection
Independent quality assurance at every stage of your order.
Quality Control, Defined
Estroute quality control is a structured inspection service that verifies product compliance through factory audits, sample checks, production supervision and pre-shipment inspection reports.
Factory Audit (验厂)
Before placing production orders, Estroute evaluates factories on production capacity, equipment, quality management systems and compliance records.
- Capacity & equipment verification against your order volume.
- Quality management system (ISO/QC process) review.
- Compliance check on materials, certifications and labor practices.
Sample Verification (样品)
Samples are checked against your specification before mass production begins, covering materials, dimensions, function and packaging.
- Pre-production sample review and approval.
- Counter-sample comparison with your reference.
- Sample fees are deductible from bulk orders.
Inspection Reports (质检报告)
Production is supervised by experienced QC engineers, with a pre-shipment inspection report delivered before dispatch.
- In-production supervision at key manufacturing stages.
- Pre-shipment inspection (AQL-based) before loading.
- Photo and data inspection reports shared with you.
How does Estroute verify factory quality?
Estroute conducts on-site or partner-based factory audits, reviews quality certifications and checks production records before approving a factory for your order.
What happens if a product fails inspection?
Failing items are rejected and reworked before shipment. Estroute coordinates correction with the factory and re-inspects before loading.
