China Warehouse QC Process: How Darkhorse Sourcing Performs Professional On-Site Product Inspection & Container Loading

In this guide, we walk you through how our team conducts real on-site quality control inside our China warehouse — opening carton boxes, verifying quantity, checking product quality, documenting defects, and preparing goods for safe container loading. Whether you are sourcing from Yiwu, Guangzhou, or any Chinese manufacturing hub, this is the level of transparency and reliability you can expect from a top China sourcing agent.

 

1. Overview of the QC Process for Global Sourcing Clients

For this particular shipment, Darkhorse Sourcing was responsible for inspecting 23 different SKUs, all consolidated into a 20-foot container with a total volume of 28 CBM.

*This client operates a mini-supermarket and imports a wide range of products, making product sourcing and quality control especially important to avoid discrepancies.

To ensure accuracy, our QC team reviews:

◆ The packing list

◆ SKU quantities

◆ Shipping marks

◆ Supplier information

◆ Required export details

 

With experience across global sourcing, strategic sourcing, supply chain sourcing, and international sourcing, our team ensures every carton is correct before loading.

 

2. Step-by-Step Quality Inspection in the Warehouse

Our warehouse receives products from different factories across China. To maintain accuracy in the sourcing process, every carton carries a unique shipping mark, allowing us to identify:

 

✔ Which supplier shipped the goods

✔ Which country the cargo will be exported to

✔ Which customer the product belongs to

 

This is standard procedure for any professional China product sourcing agent.

④ This ensures a smooth supply chain flow from China to your destination market.
