Pre-Shipment Inspection Photos: What Good Looks Like
What a useful pre-shipment photo set contains, and how to read it so problems surface before the container leaves.
The photos a buyer should demand before the balance payment
Pre-shipment inspection on a refrigerated truck is mostly photographic, and the photographs are only useful if they are specified in advance. The standard set is twelve shots taken in a fixed order at a fixed moment: after the body is complete, after the refrigeration unit has run a pull-down test, and before the unit is loaded. Any supplier can send a gallery of clean, well-lit images of a finished truck. What separates a real inspection record from marketing material is that the photos show measurements, identifiers and the state of parts that are normally hidden.
The twelve photographs, and what each one proves
| # | Photograph | What it proves |
|---|---|---|
| 1 | Chassis VIN plate, legible | The chassis is the one ordered, not a substituted unit |
| 2 | Body serial or build plate | The body is traceable to your order |
| 3 | Refrigeration unit nameplate | Model and serial match the specification |
| 4 | Controller display during pull-down | Box temperature, set point and time, in one frame |
| 5 | Thermometer placed in the rear third of the box | Temperature at the worst point, not at the evaporator |
| 6 | Panel joint with a measuring rule across it | Panel thickness as specified, not as quoted |
| 7 | Door seal, closed, with a sheet of paper pulled out | Seal contact — the paper should resist along the whole perimeter |
| 8 | Floor and drain, dry | No water ingress or blocked drain before loading |
| 9 | Interior wall, all four surfaces | No impact damage, no unfinished edges |
| 10 | Underside of the body, chassis mounting | Mounting is complete and the panel is protected |
| 11 | Full unit, four sides, in one sequence | Overall condition and options actually fitted |
| 12 | Loaded in the container or on the vessel deck | The unit you inspected is the unit that shipped |
Timing: when the photos must be taken
The moment matters as much as the content. Photographs taken after the truck has been washed and staged show condition, not workmanship. The pull-down test photo needs to be taken mid-test, with the box temperature part-way down and a clock visible, because a controller showing -18 °C on an empty box after eight hours proves very little. And the container loading photographs should be taken with the container number legible in at least one frame — that single detail links the inspection to the shipment document.
What to do with the photos when they arrive
Check four things in order. Does the VIN on the plate match the chassis number on the invoice or bill of lading? Is the refrigeration unit model the one on the order, not a “comparable” substitute? Does the controller photograph show the set point you specified? And does the door seal photograph show a full perimeter, including the bottom corner where seals fail first? Any mismatch is worth an email before the balance payment, because after shipment the leverage is gone.
Photo evidence is only one step; the full supplier check is set out in how to verify a Chinese refrigerated truck manufacturer.
Why video is worth requesting as well
A two-minute video of the pull-down, with the phone’s clock visible and the operator opening the door once, detects things photographs cannot: an unusual compressor sound, a controller that resets, a door that does not latch cleanly. It is not a substitute for the twelve photographs; it is the cheapest way to catch a fault before the unit goes into a container.
How we run it
Every export unit from Deqing is photographed against this list, and the set is sent before the balance payment rather than after shipment. For CCC-certified models the certificate number is stated on the specification data and can be checked one-to-one against the announced model code at www.cnca.gov.cn — if you want to verify the certification rather than take our word for it, that is the intended route, and we will send the certificate scan alongside the photographs.
