A decking order is not complete when the container reaches the warehouse. Before the buyer stores, sells, or installs the goods, the receiving team should inspect them.
A clear composite decking inspection can help buyers find missing goods, wrong models, damaged packaging, surface defects, and transport damage.
Most importantly, the team should inspect the goods soon after arrival. Otherwise, it may become difficult to find out when the damage happened.
For example, damage may occur during sea transport, port handling, truck delivery, unloading, or warehouse storage. Therefore, the buyer should take photos and videos before moving the pallets.
Clear records also help the buyer and composite decking supplier review the problem and agree on a solution.
1. Prepare the Order Documents
First, collect all documents before opening the container.
The inspection team should prepare:
- Purchase order
- Packing list
- Commercial invoice
- Product drawings
- Confirmed product sample
- Approved color sample
- Packaging requirements
- Pre-shipment photos
- Loading photos
- Container number
- Seal number
- Accessory list
- Packaging label details
The purchase order shows what the buyer ordered. Meanwhile, the packing list shows how many pallets, packages, boards, and accessories the decking supplier shipped.
Product drawings also help the team check the board width, thickness, profile, and side grooves. In addition, the approved sample gives the team a clear color and surface reference.
Before starting, the warehouse team should know the expected models, colors, lengths, quantities, and accessories.
As a result, workers can find order differences more quickly.
2. Check the Container Number and Seal
Next, inspect the outside of the container.
Do not remove the seal at once. Instead, take clear photos of:
- The whole container
- Container number
- Seal number
- Container doors
- Locking bars
- Side walls
- Any dents or holes
The container number and seal number should match the shipping documents. If either number is different, record it immediately.
Also, check whether the seal looks complete. A broken seal may mean that someone opened the container during transport.
After taking photos, start a video before cutting the seal. Continue filming while the team opens the doors.
This video can show the original condition of the goods before unloading.
3. Open the Container Carefully
Open the doors slowly because pallets may have moved during transport.
For example, packages may lean against the doors. Loose boards or accessories may also fall when the doors open.
After opening the container, check for:
- Fallen pallets
- Moved packages
- Loose boards
- Wet floors
- Water marks
- Damp packaging
- Loose accessories
- Strong damp smells
In addition, inspect the roof and side walls for signs of water entry.
Record all problems before workers touch the goods. Once the team unloads or restacks the pallets, the original condition becomes harder to prove.
Therefore, take both full-view photos and close-up photos before unloading begins.
4. Count the Pallets and Packages
After checking the container, compare the shipment with the packing list.
Start by counting:
- Total pallets
- Packages on each pallet
- Total packages
- Boards in each package
- Total board quantity
However, do not depend only on the pallet count. Two pallets may look similar but contain different decking products.
For this reason, check the label on every pallet.
The label should show details such as:
- Product code
- Board size
- Board length
- Color
- Quantity
- Batch number
If the order contains several models, separate them during unloading.
This step makes the final count easier and reduces warehouse mistakes.
5. Confirm the Product Details
Next, check whether the delivered products match the order.
The team should confirm:
- Product model
- Board profile
- Length
- Width
- Thickness
- Color
- Surface pattern
- Hollow or solid structure
- Side-groove design
Different composite decking products may use similar outer packaging. Therefore, workers should open selected packages instead of checking labels only.
Also, compare the actual boards with the confirmed sample and product drawing.
If the buyer ordered several colors or lengths, count each type separately.
As a result, the warehouse can enter the goods into stock correctly.
6. Inspect the Outer Packaging
Packaging can show how the goods were handled during transport.
Check for:
- Torn bags
- Crushed cartons
- Wet packaging
- Broken pallets
- Bent pallets
- Loose straps
- Broken straps
- Damaged film
- Missing corner guards
- Unclear labels
- Boards outside the package
Pay special attention to board ends and corners. These areas often receive the most impact.
If one pallet has visible damage, photograph the full pallet first. Then, take close-up photos of the damaged area.
Also, record the pallet number and package number.
After that, keep the pallet separate until the team checks the boards inside.
7. Check for Moisture Damage
Wet packaging does not always mean that the boards are unusable. However, the buyer should still record it.
Moisture may damage:
- Cartons
- Paper labels
- Wooden pallets
- Screws
- Metal clips
- Outer wrapping
First, find out whether the water came from the container, rain, or warehouse handling.
Next, open selected wet packages and inspect the goods inside.
If metal parts are wet, check for rust. Also, dry the affected goods before placing them into long-term storage.
Therefore, moisture problems need quick action even when the decking boards look normal.
8. Inspect the Board Surface
Open packages from different pallets and check the board surfaces.
Look for:
- Scratches
- Dents
- Stains
- Wear marks
- Pressure marks
- Dirt
- Oil marks
- Damaged edges
- Peeling
- Damaged co-extrusion layers
- Uneven brushing
- Unclear wood grain
Do not check only one board from the first pallet. Instead, choose boards from the front, middle, and rear of the container.
Also, select boards from upper and lower packages.
If only one board has a small mark, handling may have caused it. However, repeated defects across several pallets may show a larger problem.
For this reason, record isolated damage and repeated defects separately.
9. Compare the Board Colors
Color should be checked under the same light.
Do not compare one board in bright sunlight with another board in a dark warehouse. Also, avoid comparing wet boards with dry boards.
Instead, place several boards next to each other in one area.
Compare:
- Boards from one package
- Boards from different packages
- Boards from different pallets
- Delivered boards with the approved sample
A small color difference may be normal. However, a clear difference within the same batch should be recorded.
Take photos from the same distance and angle. In addition, include the pallet label or batch number in the photo.
This information helps the composite decking supplier review the issue more accurately.
10. Measure the Board Length
Use a tape measure to check the full board length.
Measure boards from several packages, not only one package.
Then, compare the result with the purchase order and product drawing.
Small differences may fall within the agreed range. However, repeated or large differences should be reported.
Record:
- Ordered length
- Actual length
- Number of boards checked
- Pallet number
- Package number
Also, take a photo that clearly shows the tape measure and the board end.
This type of record is more useful than a general statement that the boards are too long or too short.
11. Measure Width and Thickness
Use a caliper to check the board width and thickness.
Measure each selected board at:
- One end
- The middle
- The other end
This method helps the team find uneven sizes.
Board width and thickness can affect clip fitting, board gaps, project coverage, and final appearance.
Therefore, size checks are important before installation.
If the measurements differ from the drawing, record the highest and lowest values.
Also, note how many boards the team checked.
Clear measurements help the decking supplier understand whether the issue affects one board or a larger part of the order.
12. Check the Side Grooves
Side grooves hold the installation clips. Therefore, their size and shape can affect installation.
Check whether:
- Groove width stays even
- Groove depth matches the drawing
- Groove edges remain complete
- Clips enter the groove easily
- No material blocks the groove
- The groove has no damage
In addition, test clips with boards from several packages.
Do not test only one clip on one board.
If clips feel too loose or too tight, record the board model, clip model, and pallet number.
Photos and short videos can also show the fitting problem clearly.
13. Check Board Straightness
Place selected boards on a flat floor or table.
Then, inspect them for:
- Bowing
- Twisting
- Side bending
- Raised ends
- Uneven edges
- Local deformation
A straightedge can help the team check gaps along the board.
Small changes may come from temperature or storage. However, serious bending can cause installation problems.
For this reason, record the number of affected boards and the size of the gap.
Also, inspect boards from different pallet positions. Boards at the bottom may face different pressure from boards at the top.
14. Inspect the Board Ends
Board ends often receive impact during transport and unloading.
Look for:
- Cracks
- Broken corners
- Chipping
- Pressure marks
- Damaged hollow holes
- Split surface layers
- Uneven cutting
Some installers may cut off a small damaged part. Even so, the buyer should record the damage first.
Take one photo of the full board and another photo of the damaged end.
Also, include the package label in the record.
This evidence helps both the buyer and decking supplier judge whether the board remains usable.
15. Check the Joists
The shipment may include WPC joists, aluminum joists, or both.
Confirm:
- Joist type
- Size
- Length
- Quantity
- Material
- Color
Next, check for:
- Bending
- Cracks
- Dents
- Damaged corners
- Uneven profiles
- Impact marks
If the order includes aluminum joists, also inspect them for visible rust-like marks or surface damage.
Joists support the decking system. Therefore, damaged or incorrect joists may delay the whole project.
16. Check Clips and Screws
Count all plastic clips, stainless steel clips, starting clips, and screws.
Then, confirm:
- Clip model
- Clip size
- Screw size
- Screw material
- Screw head type
- Package quantity
Most importantly, test the clips with the actual boards.
Also, test the screws with the clips and joists.
If boxes are wet, open several boxes and check for rust.
Missing or incorrect small parts can stop installation. Therefore, accessory inspection should receive the same attention as board inspection.
17. Check Finishing Parts
The order may also include:
- Edge boards
- Fascia boards
- End caps
- Corner trims
- Cover strips
Check their quantity, size, color, surface, and profile.
In addition, compare these parts with the main decking boards.
A color or profile mismatch may affect the final project appearance.
Therefore, open at least one package of each finishing item.
If the order contains several colors, keep the finishing parts with their matching boards during warehouse storage.
18. Select Samples From Different Areas
A good composite decking inspection should cover the full shipment.
Choose samples from:
- Front pallets
- Middle pallets
- Rear pallets
- Upper packages
- Lower packages
- Different colors
- Different lengths
- Different models
If the team finds a problem, inspect more boards from the same package.
Next, check other packages on the same pallet. After that, inspect other pallets with the same batch number.
This process helps the buyer understand whether the issue affects one board, one package, one pallet, or the full batch.
As a result, the final report becomes more accurate.
19. Record Damage Clearly
A simple statement such as “many boards are damaged” does not give enough information.
Instead, record:
- Container number
- Seal number
- Pallet number
- Package number
- Product model
- Batch number
- Damage type
- Damage location
- Affected quantity
- Inspection date
- Inspector name
For each problem, take:
- A photo of the full pallet
- A photo of the package
- A photo of the full board
- A close-up photo
- A photo of the label
- A measurement photo when needed
Clear records help all parties review the same facts.
20. Record Missing Goods
When goods are missing, compare the expected quantity with the actual quantity.
Record:
- Ordered quantity
- Packing list quantity
- Received quantity
- Missing quantity
- Product model
- Color
- Length
- Pallet number
- Package number
Also, check whether the missing goods may be inside another pallet or mixed with another model.
Therefore, complete the full count before sending a final shortage report.
If the team still cannot find the items, contact the decking supplier quickly.
21. Separate Problem Products
Do not mix damaged or incorrect goods with normal stock.
Instead:
- Mark the affected pallets
- Move them to a separate area
- Keep the labels attached
- Save the original packaging
- Stop sales and installation
- Count the affected quantity
After that, expand the inspection to other goods from the same batch.
This step prevents workers from using problem boards by mistake.
It also keeps the evidence clear while the buyer and supplier review the case.
22. Contact the Supplier Quickly
Send an initial report as soon as the team finds a serious problem.
The first report should include:
- Order number
- Container number
- Product model
- Short problem description
- Estimated affected quantity
- Several clear photos
- One or two short videos
The buyer can send a full report after completing the count.
However, do not wait too long before making the first contact.
Early communication allows the composite decking supplier to check the order records and loading photos sooner.
23. Possible Solutions
The buyer and supplier may discuss several solutions.
These may include:
- Replacement boards
- Replacement accessories
- Extra goods in the next order
- Price discount
- Credit note
- Partial payment return
- Local repair
- Cutting damaged ends
- Transport claim
- Insurance claim
However, the best solution depends on the cause, quantity, damage level, contract terms, and available evidence.
Therefore, both sides should review the records before making a final decision.
The buyer should also avoid throwing away damaged goods before the case is closed.
24. Signs of Transport Damage
Transport damage often affects one local area.
Common signs include:
- Torn packaging
- Broken pallets
- Loose straps
- Fallen packages
- Boards outside the package
- Crushed board ends
- Forklift marks
- Wet cartons
- Water inside the container
- Damage near the container wall
In many cases, the outer packaging also shows damage.
For example, boards near a broken pallet corner may have the same impact marks.
However, photos taken before unloading provide the strongest evidence.
Therefore, always record the original container condition.
25. Signs of Product Quality Problems
Some problems may come from the decking products rather than transport.
Possible signs include:
- Large size differences
- Repeated surface defects
- Clear color differences
- Many bent boards
- Uneven side grooves
- Surface layer separation
- Incorrect profiles
- Wrong colors
- Clips that do not fit
- Incorrect accessories
These problems may appear in several complete packages, even when the outer packaging has no damage.
In that case, record detailed measurements and batch numbers.
Also, inspect more products to find the full scale of the issue.
26. Do Not Judge the Cause Too Early
Sometimes, the cause is not clear.
For example, a bent board may come from high heat, loose packaging, poor support, container movement, warehouse stacking, or a product problem.
Therefore, the report should focus on facts first.
Record:
- What the team found
- Where they found it
- How many boards have the issue
- Whether the packaging has damage
- Whether other pallets show the same issue
- Whether the board size matches the drawing
- Whether the issue affects installation
After that, the buyer and supplier can review the evidence together.

Conclusion
A proper composite decking inspection should begin as soon as the container arrives.
First, inspect the container number, seal, doors, and outside condition. Next, count the pallets, packages, boards, and accessories.
After that, check the packaging, board surface, color, size, shape, side grooves, joists, clips, and screws.
In addition, select samples from different parts of the shipment. If the team finds a problem, inspect more goods from the same batch.
Most importantly, keep clear photos, videos, labels, measurements, and quantity records.
As a result, the buyer and composite decking supplier can find the cause more easily and discuss a fair solution.
A standard arrival inspection also helps importers reduce losses, avoid project delays, and build a more stable relationship with their decking supplier.
