Product Inspections in China

By performing product inspections in China, we can identify problems early with the goal of eliminating the underlying causes. Utilized correctly, inspections save money by eliminating process problems and ensuring that the end-product meets customers’ requirements and expectations.

The main types of inspections we offer in China include:

First Article Inspections

Pro QC inspects first-article samples prior to volume production. This verifies that product specifications are being met and avoids unnecessary reengineering work later.

In-process Inspections

These on-site inspections in China evaluate samples of your products selected during the manufacturing process. This confirms the quality of your product and allows any necessary changes to be addressed early on, reducing rework time and costs.

Pre-shipment Inspections

During a pre-shipment inspection in China, our engineers verify that finished goods conform to your specifications.

Container Loading Supervision

Pro QC ensures that proper methods are employed during product loading, and we verify counts on-site.

Pro QC recommends ANSI Z1.4 2003 sampling tables to determine the number of units that will be randomly selected for evaluation. If you do not have existing sampling requirements, Pro QC will assist you in determining which plan works best for your specific needs. Samples are checked against a detailed inspection plan for appearance, applicable functionality, packaging integrity, workmanship, etc. If you currently do not have an inspection plan, Pro QC can assist. Defects noted are classified as major, minor, or critical depending on inspection plans. The acceptable quality level (AQL) is determined by totaling the defects and using the corresponding accept/reject criteria within the sampling plan.

Supplier Selection & Factory Audits in China

Pro QC International performs various types of factory audits in China. Whether it’s a social compliance audit, a quality system audit, manufacturing process audit or C-TPAT audit, our qualified staff is up to the task of giving you full insight into the supplier’s set-up and operations. A small investment up front in a factory audit can save you a lot of issues down the road when projects have started and problems surface.

Supplier Identification

Pro QC assists clients in identifying new suppliers globally. Whether it’s an initiative to enter a new region, demand due to growth, or a reaction to poor performance, our team works with you to develop a checklist of specific requirements and then conducts an extensive local search identifying best matches, requesting quotes, etc.

Initial Supplier Evaluation

When new suppliers are considered, we offer an Initial Supplier Evaluation that provides a one-day on-site assessment covering the primary QMS components and general capabilities:

Manufacturing Process and Quality System Audits (ISO 9001, ISO 13485, ISO 14000, IATF 16949 & GMP etc.)

Pro QC’s supplier audits evaluate all manufacturing process control systems for existing or new suppliers. Each audit report covers several areas, including evaluations of management, quality control methods, non-conforming materials, corrective action, and inspection and test equipment.

Social Accountability Audits (SA8000)

These evaluations focus on the following areas: Health and safety, discrimination, disciplinary practices, working hours, compensation, management practices, forced labor, freedom of association and child labor laws.

Sustainability/Environment Audits

Although we have offered ISO14000 (environmental) and SA8000 (social responsibility) audits for a number of years, many retailers are now requiring audits that combine elements of both of these standards along with additional elements covering energy usage, renewable energy, greenhouse gas emissions, materials and waste reduction, life cycle management, supplier’s supply chain activities and more.
Industry standards in this area are in their early stages and evolving swiftly. Pro QC’s team of auditors and supplier development professionals are ready to profile your audits for conformance to the standards emerging from your clients in both industry and retail.

Combination and Custom Audits

Pro QC offers combination and custom audits that include elements from any mix of the standard audits listed above, designed for your specific requirements and budget.

Corrective Action

Pro QC auditors conduct corrective action services utilizing the full range of quality techniques including process audits, root cause analysis, statistical quality analysis (SQA) and failure mode and effects analysis (FMEA).

We provide all three comprehensive service elements required to fully resolve product manufacturing quality issues:


Supplier Development in China

At Pro QC, we also work closely with clients and their suppliers to improve their system, processes and manufacturing capabilities. Below examples for reference:

Vendor (Supply Chain) Compliance

We assist to ensure supplier compliance with final audits required by major retailers and/or associations. Example compliance requirements we work with include Walmart, BJ’s, Lowe’s, Home Depot, Dick’s Sporting Goods, etc.

Continuous Improvement

We conduct regular 80/20 evaluations of QC data with continuous improvement initiatives developed and executed.

Certification Preparation

We assist to ensure compliance prior to the final audit. Applicable industry standards include IATF 16949, ISO 13485, ISO 9001, etc.

Product Quality

At Pro QC, we understand how critical product quality is to your business. We offer first-article, in-process and pre-shipment inspections to identify quality problems at each stage of production. Our product quality offerings also include sorting or rework service along with functional and performance testing at our labs in Ningbo, China and Monterrey, Mexico.

System Audit & Compliance

Supplier audits provide visibility into the supplier’s management system, processes, and products. These assessments are essential to ensure your suppliers qualifications and capabilities as well as their compliance to the required standards for your industry or jurisdiction. Our services also include pre-audits, corrective action plans or formal audit preparation.

Supplier Management

Our Supplier Management solution is for suppliers that fail to meet quality or performance objectives. We first identify the root-cause of the quality issues and then produce a corrective action plan. Implementation of the corrective actions and conducting regular on-site reviews will ensure your supplier exceeds your expectations and achieves sustainable improvement.

Vendor Compliance

Pro QC ensures suppliers comply with mandatory compliance terms set by major international retailers. International retail standards usually include a responsible sourcing & vendor code of conduct. We develop and monitor corrective action and preventative action plans and regularly follow up with suppliers for retailers such as Walmart, Lowe’s and many more.
