How to QC on Loongbuy is the most important skill every buyer must learn. QC (Quality Control) photos are your only defense against receiving defective, wrong, or low-quality items. This guide walks you through every step of the QC process.
What is QC and Why Does It Matter?
When you order from the Loongbuy Spreadsheet, your agent purchases the item from the seller and has it shipped to their warehouse. Before forwarding it to you, the agent takes photos — these are your QC photos. You review them and either approve the item for shipping or request an exchange.
Skipping QC is the single biggest mistake new buyers make. Without QC, you have no recourse if the item is damaged, wrong size, wrong color, or poor quality. Always, always request QC photos.

Pro QC Tips
- Save retail reference photos on your phone before ordering so you can compare instantly.
- Ask for specific angle photos if the default set misses critical details like the back logo or insole.
- Check the weight listed on the agent page — unexpectedly light items often use cheap materials.
- Look at the background of QC photos. Professional agents use clean backgrounds; messy ones may indicate rush jobs.
