On 1 January 2026, it became illegal to sell interior paint containing formaldehyde in Singapore. The National Environment Agency set the limit at under 0.01 per cent by weight, measured in-can, and the penalties run to fines of up to $50,000 or two years' imprisonment.

Good rule. Overdue, arguably. But read it carefully, because of what it leaves out.

It covers paint. It does not cover the boards your wardrobe is made of.

The regulation, precisely

NEA's announcement is narrow and specific: interior paints sold in Singapore must contain less than 0.01% w/w total in-can formaldehyde. Industrial paints and exterior paints are excluded. The reasoning is straightforward — formaldehyde is used as a preservative in water-based paint, it accumulates in enclosed spaces, and prolonged exposure causes respiratory irritation and worse.

Every word of that reasoning applies at least as strongly to composite wood. None of the regulation does.

Parliament already knows

This is not an oversight nobody has noticed. On 6 August 2024, the Ministry of Sustainability and the Environment answered parliamentary questions on indoor formaldehyde levels. Members asked about paints, about penalties, about imported furniture, and about whether formaldehyde should be regulated as a hazardous substance outright.

The Ministry's answer named the other sources directly — composite wood products and adhesives that may emit formaldehyde. It noted that the furniture industry has worked on the problem through guidelines developed by the Alliance for Action on Sustainable Spaces. Voluntary guidelines.

On regulating composite wood the way paint has now been regulated, the position was that NEA is actively studying the issue.

Actively studying is not a rule. Until it becomes one, the board in your kitchen carcass is governed by whatever your contractor decided to buy.

Why boards matter more than paint

Consider the physical reality of a renovated flat.

Paint is a thin film on a wall, and it cures. Most of what it is going to release, it releases in the first weeks, and the surface is sealed and exposed to whatever airflow the room has.

Carpentry is different in every way that matters. A typical four-room flat carries somewhere between forty and eighty square metres of board once you count both faces of every panel, every shelf, every drawer box, every carcass side. Much of that surface is unsealed — the inside of a wardrobe, the back of a cabinet, the underside of a shelf. And most of it sits inside enclosed volumes that stay shut for days at a time.

Then there is time. Urea-formaldehyde resin does not finish releasing in a fortnight. It hydrolyses slowly, and it accelerates with heat and humidity — which is a fair description of Singapore, and an exact description of a wardrobe on an west-facing wall in the afternoon.

So: more surface, less sealing, worse ventilation, longer duration. If you were designing a system to load an apartment with formaldehyde, you would build cabinets, not paint walls.

What the grades actually mean

Board is graded by how much formaldehyde it releases in a controlled chamber test, measured in milligrams per cubic metre of air.

Under GB/T 39600-2021, the standard most boards sold here are graded against, ENF is the lowest class at no more than 0.025 mg/m³. E1 permits up to 0.124 mg/m³ — roughly five times the ENF ceiling. E2 sits higher still.

Here is the part that catches people out. E1 is frequently sold as the safe choice, the responsible upgrade, the thing you pay a little more for. It is a legal grade and it is not a scandal. But it is not the low-emission option; it is the middle. And E2 remains the quiet default in a great deal of budget carpentry, because it is cheaper and because nothing on a finished door tells you which one you got.

You cannot see the difference. You cannot reliably smell the difference after the first month. The only way to know is to have decided before the panel was cut.

There is an industry built on the other end of this

Search for formaldehyde removal in Singapore and you will find a competitive market. Specialist cleaning firms, odour-removal services, photocatalytic coating treatments, air-quality testing, companies whose entire business is arriving after your renovation and dealing with what it released.

They advertise. They rank. They are busy. That is not a market that exists because of a marketing campaign — it exists because a large number of Singaporeans finish a renovation, move in, and discover their new home smells wrong and their eyes sting.

Treat that industry as data. It is a fairly precise measurement of how often this goes badly, and of how many people are willing to pay twice — once for the carpentry, again to mitigate it.

Paying to remove formaldehyde is a strange transaction when the alternative was not putting it in.

What to ask, and what a real answer sounds like

If you are quoting renovations right now, four questions separate a firm that knows from a firm that is guessing.

"What grade is the carcass board, and to which standard?" You want a specific pairing — ENF to GB/T 39600-2021. If the answer is "E0 board, very safe one", that is a category with no number attached and no standard cited. Ask again.

"Is that the standard, or an upgrade?" Plenty of firms will supply ENF if you insist and pay. That is a different proposition from a firm where it is simply what goes in every job, priced in.

"Can I see the test certificate?" SGS or equivalent, for the board actually being used, not a generic brochure.

"Where is it cut?" Board grade is a purchasing decision, and purchasing decisions get changed when margins get thin. A firm that fabricates its own carpentry is answerable for the substitution in a way a firm that buys finished units is not.

A firm that has thought about this will answer all four in under a minute. A firm that has not will change the subject to design.

Where we stand

We use SGS-tested ENF-grade carcass board as standard on all carpentry. Not as an upgrade, not on request, not on the premium package — as the default, on every job, priced in.

We are not neutral here and it would be silly to pretend otherwise. We built around this, and an article arguing that board grade matters is an article arguing that you should care about something we happen to sell. Read it with that in mind.

But the underlying facts are not ours. The paint ban is NEA's. The acknowledgement that composite wood emits formaldehyde is the Ministry's, on the parliamentary record. The grades are a published standard. The removal industry is in your search results.

The regulation will probably come. NEA is studying it, and paint was studied before it was banned. When it arrives, it will apply to boards bought after it arrives — not to the wardrobe you installed this year, in the bedroom where somebody sleeps eight hours a night.

That decision is being made now, in your quote, whether or not anybody has raised it with you.

If you want to see what it looks like in practice, our factory is at 2 Defu South Street 1. Come and watch a panel get cut, and take an offcut home to smell for yourself.
