1688 Pre-Shipment Inspection: Full QC Process Guide covers exactly one moment in your sourcing timeline: the hour or two before your goods leave the factory or consolidation warehouse in China. Miss this window and every defect becomes your problem, not the supplier's.
Why Pre-Shipment Inspection Is Mandatory, Not Optional
A lot of operators confuse this step with supplier vetting. They are not the same thing. Checking a supplier's credentials, transaction history, and reviews happens before you place a deposit, and we cover that separately in our guide to verifying a 1688 supplier before you pay a deposit. Pre-shipment inspection happens after production is done, when the goods are packed and sitting in a warehouse waiting for a truck to the port or airport.
The distinction matters because the cost of catching a problem changes completely depending on which side of "goods left China" you are standing on. Before shipment, a defect is the factory's problem: they repack, they swap units, they eat the cost of a short pack. After shipment, it becomes your problem, full stop.
Here is a scenario I see constantly. A shop owner orders 500 units of a kitchen gadget, pays the balance, and the factory ships. Three weeks later the goods clear customs in Vietnam or Philippines and 8 percent (40 units) turn out to have cracked housings or missing accessories. At that point, no factory accepts a return. Why would they? The goods already passed through a freight forwarder, got consolidated with other shipments, and cleared customs under your name. The factory can reasonably say "how do we know it wasn't damaged in transit or during your local handling." You have no leverage left, and $200 to $400 in landed cost is gone.
This inspection point is also the last moment you can act before your order gets physically merged with cargo from other factories in a shared container. Once consolidation happens, tracing a specific defect back to a specific factory gets messy fast. If you are gathering orders from three or four different suppliers into one container, this is your last clean checkpoint to catch problems while each factory's goods are still separable.
The 1688 Factory QC Process, Step by Step
A workable pre-shipment QC process at the factory or consolidation warehouse level breaks into five steps.
Step 1: Get notified when goods are ready, and lock in an inspection date. Ask the factory or consolidator to flag you 2 to 3 days before their planned ship date. Do not let "ready to ship" mean "already loaded onto the truck." Confirm the inspection slot in writing (WeChat message with a timestamp works fine) before you agree to a ship date.
Step 2: Count cartons and reconcile against the packing list and original PO. Before opening a single box, verify the total carton count matches what the packing list says, and that the packing list quantity matches your original order. Shortages get caught here, not after arrival.
Step 3: Open a sample of cartons based on a sampling ratio, not just one box. A common rule of thumb is 2.5 percent to 5 percent of cartons depending on order value, with a minimum of 3 to 5 cartons on small orders. Never accept "we opened one box, looks fine" as a substitute for a real sample across the batch. Defects cluster, they do not distribute evenly.
Step 4: Compare physical product against the listing photos and specs you agreed on at order time. Color, print placement, material weight, accessory count. Take screenshots of the original 1688 listing before the call or visit so you have a fixed reference, not memory.
Step 5: Document everything before you sign off on release. Photos of open cartons, video of the sampled units, a written inspection note with date, carton numbers checked, and defect count if any. Only after this record exists should you confirm the factory can proceed to ship.
Video Call Inspection for 1688: How to Do It Without Getting Played
For small orders, flying someone to Yiwu or Guangzhou to inspect in person is not realistic. Video call inspection works, but only if you run it with structure instead of letting the factory drive.
Send a checklist and a list of specific camera angles before the call. Do not ask "show me the goods" and let the factory pick what to point the camera at. Specify: full stack of cartons from 3 meters back, carton labels close up, then interior of specific cartons you name during the call.
Ask for a wide shot of the entire lot first, then name a carton number at random for them to open on camera. This is the single most important trick: if you name the carton to open only after seeing the wide shot, you remove the factory's ability to pre-stage a "good" carton for the camera.
Require a real-time timestamp check. Ask the staff member to hold up a piece of paper with the current date written by hand, or open their phone's clock app on camera. This kills the oldest trick in the book, a pre-recorded video of a perfect carton looped for every buyer who calls.
Know the limits. Video calls cannot tell you about material durability, fabric weight, or whether a coating will flake after a wash cycle. They are good for catching wrong color, wrong print, missing accessories, and obvious cosmetic damage. For anything higher value or more technical (electronics, textiles with durability claims), a video call alone is not enough. If you have not already read our breakdown of how to read 1688 seller ratings and reviews, that is the earlier-stage check, this is the physical, execution-stage one.
When to Pay for a Third-Party Inspection Service Before Consolidation
There is a point where doing this yourself stops making sense.
If your shipment is high value, spans many SKUs, or pulls from multiple factories into one container, a third-party inspector earns their fee back the first time they catch a problem. Same goes for shop owners who do not speak Mandarin or simply cannot block out an hour per factory for video calls when they are juggling five orders in the same week.
Third-party inspection services around Guangzhou and Yiwu typically charge by the hour (roughly $80 to $150 per inspector-day, sometimes billed per shipment instead) depending on scope and how many factories they need to visit in one trip. For a multi-factory consolidation, one inspector visiting three or four factories in a single day is far cheaper per stop than three separate trips.
When picking an inspection agency, ask for a sample report before you book anything. A good report includes carton-by-carton counts, close-up defect photos, and a clear pass/fail call, not vague language like "generally acceptable." Also ask directly what happens if they miss a defect: some agencies offer a partial fee refund or re-inspection, others offer nothing. Get that answer before you pay, not after a claim.
This step matters most in exactly the scenario covered in our guide to consolidating orders from multiple 1688 factories: once goods from different factories sit in the same container, you lose the ability to isolate which factory caused which defect.
Pre-Shipment Inspection Checklist (Use This Directly)
Four categories to check on every inspection, no exceptions: quantity (carton count vs packing list vs PO), appearance (color, finish, visible damage), specs (dimensions, materials, accessory count vs the original listing), and packaging (cushioning, box condition, whether the pack will survive a 15 to 20 day sea freight transit).
A minimum viable inspection record needs three things: photos of the sampled cartons, video of at least the wide shot and one detailed open-carton segment, and a signature or written confirmation from whoever conducted the check, factory staff, your own team, or a hired inspector.
Keep inspection records filed per shipment, not just per factory. When a dispute comes up three months later about a specific batch, you want to pull the exact inspection note for that PO number, not dig through a WeChat thread.
If you are running more than two or three active POs at once, attaching a QC checklist directly to each order in a tracking tool beats keeping notes scattered across chat apps and spreadsheets. That is one of the gaps we are building toward in Ordinex Orders.
Common Mistakes That Still Let Defective Goods Through
Even shop owners who "do inspection" still get burned, usually for one of these reasons.
Checking only 1 or 2 cartons out of a batch of 20 or 30 and calling it done. A 5 percent sample on a 30-carton order is still 1 to 2 cartons, but it needs to be randomly selected at the time of inspection, not picked in advance by the factory.
Accepting a video the factory recorded on their own time and sent over, with no real-time verification. This is the single biggest gap between "I did a video inspection" and an inspection that actually protects you.
Skipping inspection entirely on small, low-value orders because it feels like too much effort for the dollar amount. This is exactly how defect rates creep up over a year of small orders that never got checked.
Not keeping any photo, video, or written record of the inspection. Without documentation, you have zero leverage in a dispute. A factory that denies responsibility wins by default when you cannot produce evidence.

FAQ: 1688 Pre-Shipment Inspection
Do I need to inspect every single order, even small ones under $500? Yes, at minimum a quick video call with the wide-shot-then-random-carton method. Skipping small orders is exactly where defect rates quietly build up over months.
What sampling ratio should I use for a large order? 2.5 percent to 5 percent of total cartons is standard, with a floor of 3 to 5 cartons even on smaller batches. Higher value or higher SKU count orders should sit toward the 5 percent end.
Can I trust a video the factory records and sends me afterward? Not on its own. Always require a live call with a real-time timestamp check (handwritten note or phone clock on camera) before you sign off.
Is a third-party inspector worth it for a single-factory order? Usually not, unless the order value is high or the product is technically complex. Single-factory small orders are well suited to a structured video call instead.
What happens if I skip inspection and defects show up after arrival? In almost all cases the factory will not accept returns or replacements once goods have cleared customs under your name. The cost of the defect becomes fully yours.
