Pre-shipment inspection is the most widely used quality control service in international trade. Conducted when 80–100% of your order is manufactured and export-packed, it provides a statistically valid assessment of product quality before goods leave the factory. Our inspectors use AQL (Acceptable Quality Level) sampling based on ISO 2859-1 to randomly select units from the production lot, then evaluate each sample for visual defects, dimensional accuracy, functional performance, labeling compliance, and packaging integrity.
Every defect found is classified as critical, major, or minor according to your quality criteria, and documented with on-site photographs. The resulting inspection report — delivered within 24 hours — gives you a clear pass, fail, or pending verdict along with actionable data to make informed shipping decisions. Whether you source consumer electronics, garments, furniture, or industrial components, a pre-shipment inspection is your last line of defense against costly returns, chargebacks, customs rejections, and brand damage.
