Product Quality Control

Our Quality Control team is comprised of certified professionals who conduct thorough inspections both before and after production, ensuring that the products meet the required quality standards and specifications.

Types of Quality Control Service

	100% Quality Inspection
100% product inspection is a quality control process where every individual unit of a product is examined and tested for defects, ensuring that each item meets specified quality standards before it is shipped or made available to customers. This comprehensive inspection approach aims to minimize the risk of defective products reaching the market and helps maintain consistent product quality.

Acceptable Quality Limit Inspection

Acceptable Quality Limit (AQL) Inspection is a quality control method that involves sampling a batch of products for inspection, rather than examining each individual unit. AQL sets specific acceptable and unacceptable quality thresholds, and the inspection determines whether the sampled products conform to these criteria. It’s a statistical approach to assess the overall quality of a production run while minimizing inspection costs.

	Amazon FBA Inspection
Amazon FBA Inspection is the process of examining and evaluating products stored in Amazon’s fulfillment centers to ensure they meet quality and safety standards. This inspection is conducted by Amazon to verify that products are accurately labeled, packaged, and ready for fulfillment to customers. It helps maintain product quality and customer satisfaction.

CE Compliance

CE Compliance, often referred to as CE Marking, is a certification that indicates a product’s compliance with the essential health, safety, and environmental protection standards within the European Economic Area (EEA). It is mandatory for many products sold in the EEA and signifies that the product meets specific regulatory requirements, allowing it to be legally marketed and used within the region.

Container Loading Check

A Container Loading Check is a quality control inspection that takes place at the time of loading goods into shipping containers for international transportation. It ensures that products are loaded correctly, securely, and in accordance with specific shipping requirements, thereby minimizing the risk of damage during transit and ensuring efficient container space utilization. This check is essential for maintaining product integrity throughout the shipping process.

Factory Audit Service

A Factory Audit Service is a professional assessment conducted by an independent agency to evaluate a manufacturing facility’s operations, quality control, compliance with industry standards, and overall production capabilities. It aims to provide insights into a factory’s reliability, ensuring it can consistently meet quality and safety requirements. This service is commonly used by businesses to assess potential suppliers or monitor their existing manufacturing partners.

First Article Inspection

A First Article Inspection (FAI) is a comprehensive and documented examination of the initial product or component produced in a manufacturing run. It involves detailed measurement, testing, and verification to ensure that the first item in a production run meets specified requirements, design specifications, and quality standards. FAI is often conducted to validate the manufacturing process and product design before full-scale production begins.

In Production Inspection

In-Production Inspection is a quality control process that takes place during the manufacturing process, rather than before or after. It involves inspecting a random sample of products while they are being produced to ensure that quality standards and specifications are being met. This inspection helps identify and address any issues or defects early in the production cycle, reducing the risk of producing a large quantity of non-conforming products.

Post Production Inspection

Post-Production Inspection is a quality control process that occurs after the manufacturing of products is completed. It involves examining a sample of finished products to ensure they meet the specified quality standards and conform to design specifications. This inspection helps identify and rectify any defects or issues that may have arisen during the manufacturing process before the products are shipped or made available to customers.

	Pre-Production Inspection
Pre-Production Inspection is a quality control process that occurs before the actual manufacturing process begins. It involves checking the materials, components, and production processes to ensure they meet the required quality and specification standards. This inspection helps prevent potential issues and ensures that production starts with the right materials and processes in place.

Pre-Shipment Inspection

Pre-Shipment Inspection (PSI) is a quality control process that takes place just before the products are ready for shipment. It involves examining a random sample of finished goods to check for compliance with quality standards, specifications, and order requirements. The goal is to identify any defects or issues that may exist in the products before they are shipped to customers, helping to ensure product quality and customer satisfaction.

	Supplier Background Check
A Supplier Background Check is an evaluation of a potential supplier’s credentials, history, and reputation. It involves researching and verifying information about the supplier’s financial stability, legal standing, manufacturing capabilities, and past performance. This check helps businesses assess the suitability and reliability of a supplier before entering into a business relationship.
