IN SHORT
Check a plywood delivery before any sheet is cut: match the sheet count, size, thickness and grade wording against your order, look at the faces, edges and flatness, and look for signs of moisture on the pallet. Write any problem on the delivery note and photograph it first, because once a sheet is cut it is hard to show what was wrong with it.
The pallet is on the ground, the driver wants a signature and the cutting list is already waiting. It is a good moment to raise a problem, and an inconvenient one to go looking for it. This checklist is for cabinet makers, contractors and dealers who receive plywood and want a short, repeatable routine before the first cut.
Start with the paperwork and the pallet, not the boards. Put your purchase order or quotation next to the delivery note and compare the line items: the thickness, the sheet size, the sheet count and whatever grade or finish wording was on the quote. Then walk around the pallet. Look for torn or wet wrapping, crushed corners, straps that have loosened, and sheets that have shifted so that edges stick out. These are the things a driver and a buyer can both see quickly, and they are the easiest to record before the vehicle leaves. If the count is short or the wrapping is damaged, say so on the delivery note before you sign, and take a photograph that shows the pallet and the note together. A signature with no remark may be treated as acceptance. You are not accusing anyone by doing this; you are keeping a record that the supplier and the logistics company can both refer to later.
Pull a few sheets from different heights in the stack, not only the top one, and measure them against your spec. JIYU stocks 18mm, which is built from 11 layers, and 6mm for backs and drawer bottoms, in the 2440mm × 1220mm size, which is the 4×8 sheet. Measure with a caliper or a steel rule rather than judging by eye, and measure at the middle of the edge as well as near the corners, so that you compare several points. Decide your own acceptable tolerance for the job before the delivery arrives, so that you are comparing against a figure you set in advance. If you build to tight joinery, check that every sheet in your sample is the same thickness as the others, since a mixed stack can lead to uneven carcass joints. If you need another thickness, ask whether it can be ordered, because only 18mm and 6mm are held in stock.
Lift a few sheets and look at both faces under good light. Scratches, dents, chipped corners, bubbles or lifted patches in the surface layer, and colour or grain that does not match across the sheets you will use for one job are all worth noting. JIYU's boards carry a melamine finish in plain colours, wood grains and other patterns, and the 6mm back panel is finished on one side only, so check that the finished side is the one you expected. Then turn to the edge, because the edge shows how the board is built. You should see the cross-laminated layers lying in neat, continuous lines; for an 18mm JIYU board that means counting 11. Look for gaps between layers, soft or crumbly spots, and voids where a layer looks missing. A board with a clean face can still have a poor core, and the edge is a good place to check. Mark any sheet that looks wrong with tape so that it does not get mixed back into the stack.
Malaysia is humid, and a pallet can sit in a container, a lorry or an open yard for a while before it reaches you. Look at the stack from the end: a clean stack lies flat, while a bowed or twisted sheet shows as a curve you can see along the edge. Sight down the length of a few sheets, or lay one on a flat floor and check whether the corners lift. Check the pallet underside and the bottom sheets for water staining, swollen or rough edges, and any damp smell or mould-like marks on the wrapping. If the wrapping has been torn open, treat the sheets near the opening with extra suspicion. Once you accept the delivery, store the sheets flat on a level support, off the floor and under cover, with the wrapping kept on until you need them. Sheets stood on an edge against a wall can bend, and a stack left in the open on a wet floor can take up moisture from below. Note which part of the stack each damaged sheet came from.
Not with a ruler or by eye. Formaldehyde release is measured in a laboratory under GB/T 39600-2021, which sets ENF at no more than 0.025 mg/m³, E0 at 0.050 mg/m³ and E1 at 0.124 mg/m³. What you can do on delivery day is match the grade wording on the quote to the wording on the delivery note, and keep the supplier's test report on file. JIYU's report, JC26-WT0087 from the Liuzhou Quality Inspection and Testing Research Center, covers a submitted sample, which measured 0.022 mg/m³ and was judged ENF grade; it is a record for that sample, not a reading taken on the sheets on your pallet. The factory's own quality checks are an internal process and are separate from a third-party report, so keep the two apart when you write them down. If a supplier cannot show a report for the grade it quotes, that is worth raising before the next order, not after the boards are cut.
Stop and do not cut the affected sheets. Cutting changes the board, and it makes a claim much harder to explain. Photograph the problem with the delivery note, the pallet and a tape measure or a ruler in the frame, set the sheets aside, and tell the supplier the same day, with your order reference, the photographs and a short description of what you found. Separate two kinds of issue: a delivery problem, such as a short count or damage in transit, which should go on the delivery note and be raised with the supplier and the logistics company; and a board problem, such as delamination, warping or bubbling in the surface, which you report with photographs. JIYU's board carries a 10-year one-to-one limited warranty covering manufacturing defects only: delamination, cracking not caused by external force, and moisture blistering caused by a manufacturing defect.
How many sheets should I inspect when a pallet arrives?
Count every sheet on the pallet against the delivery note, then look closely at a spread of sheets taken from the top, middle and bottom of the stack. If the sample shows a problem, widen the check to the rest of the stack rather than assuming the others are fine.
What if I only notice a problem after cutting a few sheets?
Stop cutting, keep the offcuts and the remaining sheets from the same pallet, take photographs showing the defect, and contact the supplier with your order reference. Offcuts and uncut sheets show what you received, so do not throw them away.
Is it enough to check the face of the board?
No. The face shows the finish, while the edge shows the cross-laminated layers and any gaps or voids in the core, so look at both.
How should I store plywood once the delivery is accepted?
Keep the sheets flat on a level support, off the floor and under cover, with the wrapping on until the sheets are needed. Standing sheets on an edge against a wall can bend them, and a stack left on a damp floor can take up moisture from below.
