How to Check a Vietnam Plywood Mill Before You Order

September 21, 2026

The panel you get is decided before the first sheet is pressed, by who you chose and what you wrote down. These are the checks that pay for themselves, in the order they matter.

Factory or trading company

Nothing is wrong with buying through a trader, as long as you know that is what you are doing, because a trader cannot change what happens at the press.

Ask for the business licence and the tax code, then ask questions about production:

• How many presses, and what size?
• What is the press cycle for an 18 mm panel?
• What is the daily output in sheets or cubic metres?
• Who does the sanding and the grading, and where does the rejected stock go?

A factory answers these in seconds because it is their day. A trader gives general answers and moves the conversation back to price. Then ask for a live video walk through of the line while your product is running. That single call tells you more than a folder of photographs.

Export history

A mill that has shipped to your market before knows what your documents look like. One that has not will learn on your order, and the learning happens on your money.

Ask which markets they already ship to, which documents they have produced, and for the name of the forwarder they use. First time exporters can be excellent producers. Just price the delay into your planning rather than assuming it away.

Certificate scope

Certificates belong to a factory and a product line, not to an industry. The three questions are always the same: does the certificate name this factory, who issued it, and which line does it cover. For the US rules there is a longer version of this check in CARB P2 and TSCA Title VI for Vietnam plywood.

Ask for the certificate number and check it against the issuing body rather than against the scan you were sent.

The sample, and what to do with it

A sample approved and then forgotten is a sample wasted. Keep it.

1. Get samples from production, not from the showroom shelf.
2. Mark them, photograph them and keep one in your office. That is your retained sample.
3. Write the sample number into the purchase order, so the contract refers to a physical object.

When the container lands, measure against that sample: actual thickness with a caliper at several points, the glue lines on a cut edge, the face grade, the core for gaps, the weight of a sheet. Nominal 18 mm arriving as 17.2 mm is the most common gap between order and delivery, and it is also the easiest one to prove.

Inspection at loading

A pre shipment inspection is a person standing in the factory with your specification while the container is filled. It costs a few hundred dollars and it is the only check that happens while the goods can still be stopped.

Tell the inspector what to measure rather than asking for a general look: thickness at set points, moisture content, ply count on a cut sample, glue line, face grade, sheet count, labels and packing. Agree in advance what happens when the report comes back short, because that is the conversation nobody wants to have for the first time on the day of loading.

The two problems that actually happen

Core species substitution. A cheaper species or a combi core goes in mid production, usually when the mill is squeezed on price. Caught by a cut sample against the retained sample, and by ply count.

Bond downgrade. MR or light melamine glue instead of the phenolic you contracted. Caught by the glue line and by a boil test, and described in MR, melamine or WBP.

Both are addressed by the same two contract lines: the specification names the core build and the bond, and the mill has to tell you before changing either. Everything else is inspection.

What good looks like

A mill worth a running account answers technical questions directly, says no to the products it does not press well, sends production samples without being chased, and tells you when a delivery date is at risk rather than after it has slipped. Price matters, and it moves less than most buyers expect once the specification is fixed. The rest of the price is broken down in what drives the price of Vietnam plywood.

The mill check is stage 3 of the route in our guide to import plywood from Vietnam. For what a certificate claim does and does not prove, see FSC vs PEFC vs FLEGT for plywood.
