Inspection items of various face masks quality inspection: filter efficiency test, quality test, tightness, air tightness, active carbon component test, microorganism test, ethylene oxide residue, dust resistance efficiency, filter element test, etc.

From August 1, 2009, gb2626-2006 respiratory protective equipment self-priming filter type particle respirator was implemented, which stipulated that the protection levels for particles were Kn90, kn95 and kn100. The protection levels of oil particles are kp90, kp95 and kp100. The filtration efficiency was 90%, 95% and 99.97% respectively. Kn100 and kp100 are of high protection level. According to the national gb2626-2006 standard, the filter elements of dust masks shall be printed with permanent identification: ‘gb2626-2006-kn100’ national standard, year number and protection grade identification. The higher the degree of protection and filtering efficiency, the higher the safety of the dust mask.

Protection performance for fine particles (PM2.5) The protection effect level is set according to the air quality category in the national air quality standard. The protection effect level is divided into four levels from low to high: Level D, level C, level B and level A. The corresponding use environment is as follows: Level D is suitable for moderate (PM2.5 concentration no more than 150 g / m3) and below pollution, level C is suitable for severe (PM2.5 concentration no more than 250 g / m3) and below pollution, and level B is suitable for severe pollution Dye (PM2.5 concentration no more than 350? g / m3) and grade A are used when PM2.5 concentration reaches 500? g / m3. Wear mask reasonably according to the standard requirements, which can reduce the concentration of PM2.5 inhaled to less than 75? g / m3, and make the air quality in the inhaled body reach good or above level.

Product Inspection China: Fix the #1 Risk in Sourcing

Why Product Inspection in China is Non-Negotiable

When you source products from China, the stakes are higher than ever. Imagine investing months and significant resources into a new product, only to have it recalled or rejected at the final stage. Sounds complex? It’s a reality that many importers face every year, and the consequences can be severe for your brand, your customers, and your bottom line.

The Hidden Costs of Skipping Quality Control

According to data from China’s State Administration for Market Regulation, numerous hardgoods and children’s products were recalled in the first quarter of 2025 alone, underscoring the ongoing risks of supply chain nonconformities.

But product recalls are only part of the picture. The real costs of skipping proper product inspection in China go far beyond the immediate loss of goods. You’ll notice ripple effects like:

  • Damaged brand reputation and loss of customer trust
  • Unexpected shipping delays and extra logistics costs
  • Legal liability for non-compliance with international standards
  • Potential business disruption if suppliers go bankrupt or fail to deliver quality

As highlighted in recent supply chain risk reports, overreliance on Chinese suppliers can expose companies to sudden disruptions, ESG violations, and even supplier insolvencies—all of which can halt production and increase costs (Supply Chain Dive).

Robust quality control in China isn’t just about catching defects—it’s a strategic investment in your business’s long-term stability and reputation. By implementing reliable inspection processes, you can minimize defects, ensure compliance, and maintain a competitive edge in the global marketplace.

What You Will Learn in This Guide

This comprehensive guide will walk you through the essentials of product inspection China for 2025. You’ll learn:

  • Why quality control in China is crucial for every importer
  • The main types of inspections and when to use them
  • How to set effective quality benchmarks and avoid costly mistakes
  • Best practices for choosing trustworthy inspection partners
  • Actionable steps to resolve issues and protect your supply chain

Whether you’re new to sourcing or looking to optimize your existing processes, mastering China quality control is the first step to securing your business’s future.

A Guide to Key Inspection Types and Timelines

When you’re sourcing from overseas, how do you know your products will actually meet your expectations? That’s where understanding the main types of product inspections in China becomes essential. Each inspection serves a distinct purpose, happens at a different stage in the supply chain, and can dramatically impact your risk profile, budget, and customer satisfaction. Let’s break down the four primary inspection types you’ll encounter—and how to decide which is right for your needs.

Inspection Type When It’s Done Primary Goal Best For…
Pre-Production Inspection (PPI) Before manufacturing begins Verify raw materials, components, and factory readiness New suppliers, complex products, high-value orders
During Production Inspection (DPI/DUPRO) When 10-60% of production is complete Identify defects early, ensure process consistency Ongoing orders, first-time runs, tight deadlines
Pre-Shipment Inspection (PSI) After at least 80% of goods are packed, before shipment Confirm finished goods meet quality and regulatory standards All orders, especially export shipments, e-commerce
Container Loading Check (CLC) During container loading at the factory/warehouse Ensure correct products are loaded and handled safely Fragile, high-value, or mixed shipments

Pre-Production Inspection (PPI)

Imagine catching a materials issue before hundreds of units are produced. That’s the value of a Pre-Production Inspection. Conducted before manufacturing starts, a PPI checks that raw materials, components, and factory equipment match your requirements. Inspectors may also review the supplier’s readiness, including their ability to follow your specifications and meet safety or environmental standards. This step is especially vital with new factories, customized orders, or when you’re scaling up production.

During Production Inspection (DPI/DUPRO)

Ever worry that problems might go unnoticed until it’s too late? A DPI, also known as DUPRO, is performed when about 10-60% of your order is complete. This allows you to spot and correct issues early—whether it’s inconsistent assembly, color mismatches, or workmanship defects. By catching errors mid-production, you reduce the risk of costly rework or missed shipping deadlines. For brands with ongoing orders or strict timelines, DPI is a smart way to keep quality on track and build trust with your supplier through proactive feedback.

Pre-Shipment Inspection (PSI)

This is the most widely used checkpoint in the world of product inspection in China. A Pre-Shipment Inspection occurs after at least 80% of goods are packed but before they leave the factory. The goal? To verify that finished products meet your quality standards, match order specifications, and comply with regulatory requirements. Inspectors check everything from product quantity and labeling to packaging and functionality. By leveraging pre shipment inspection services in China, you can avoid shipping defective or non-compliant goods—saving you from expensive returns, customs delays, and unhappy customers.

Container Loading Check (CLC)

Even if your products pass QC inspection in China, improper loading can lead to damage in transit. The Container Loading Check is your last line of defense. Inspectors monitor the loading process, ensuring that goods are handled carefully, packed securely, and loaded according to your instructions. This is especially critical for fragile or high-value items, as well as mixed shipments that require precise organization.

Choosing the right inspection—or combination of inspections—depends on your product type, order size, and risk tolerance. Many importers use a blend of these services to create a robust qc inspection strategy. For example, you might start with a PPI for a new supplier, add a DPI for complex products, and always finish with a pre-shipment inspection in China before approving payment or shipment. The right approach helps you catch problems early, avoid surprises, and ensure your goods consistently meet expectations.

Next, let’s demystify how quality standards are actually measured in China—and why understanding AQL is key to making your inspections meaningful.
