The product is fine. It is the paperwork that gets the shipment stopped.
An EU inspector checks one thing above all: does every claim in your Safety Data Sheet (SDS) have a real, checkable source behind it. That is exactly how we built this catalogue — every value carries its source, and where there is no source, the system says so out loud. It is also exactly how the free SDS audit works: we tell you whether the sheet you already have is EU-valid, source by source.
A confident-looking document is not a safe one
Most chemical databases share one flaw: confident answers with nothing behind them. Averaged classifications, copied-over errors, „verified” badges a system awards to itself. When that reaches your SDS and reaches an EU border, the goods sit in the port while demurrage accrues, your delivery date passes, and your European buyer starts calling a competitor. The product was never the problem. The paperwork was — and you lose the account over a document.
No source means „unverified” — never the reverse
We built this catalogue on one rule: every claim must have a source, and if there is no source, the system says so openly. It will never dress an unknown up as a confirmed value. In chemistry, a false „safe” is more dangerous than an honest „we don’t know”.
Green checkmarks are easy; honest question marks are engineering. Anyone can print a tick; showing exactly where the data runs out is the harder, more honest thing to build.
Three states for every fact
Every piece of data in the catalogue carries one of three plain statuses, so you always know how much weight it can bear:
- Verified — the value comes from a specific, checkable source: a harmonised classification from Annex VI of the EU CLP regulation (the EU’s legally binding hazard-classification list) with its index number; an occupational exposure limit (the legal airborne limit for a substance in the workplace) from an official member-state list; an IARC cancer monograph (from the WHO’s cancer research agency) with its volume number. The source sits next to the value. You can check it yourself.
- Aggregated — the value comes from a recognised collective database (for example, experimental data pooled by PubChem) and is labelled as such. You know where it came from and how much it weighs.
- Unverified — we could not find a confirmed source, so we say so and recommend you verify it before use. It does not mean the value does not exist; it means we will not invent one to fill the gap.
Where the data comes from
- Hazard classification: only the harmonised classification from Annex VI of the CLP regulation, with the substance index number. We do not average self-classification notices scraped from the web — that is the most common source of inflated hazard claims in other databases. Where a substance has no harmonised classification, we mark it plainly.
- Occupational exposure limits: from official regulatory lists, cited to their legal source — for example, a member-state limit shown as one national example, not copied from a loose table. We do not anchor the whole catalogue to any single country. An exposure limit given with no legal basis is a defect inspectors commonly record.
- Carcinogenicity: IARC monographs, in the same three-state model — the substance is classified (with its group number and citation), verified as not listed, or marked unverified. Never „no data” dressed up as „safe”.
- References: every entry is validated — we check that the DOI (the permanent digital identifier of a published paper) exists and points to the work cited. False and non-existent identifiers are rejected automatically.
What we do not do
- We do not show percentage „confidence scores” with no method behind them.
- We do not award ourselves certificates.
- We do not copy a competitor’s sheets.
- We do not hide gaps. An absence is information, and we treat it as one. No „verified” badge appears without a source.
This is exactly how we would check your SDS
The method above is not just for our catalogue. Send us the sheet you already have — the one a supplier handed you, not one we write for you — plus your destination country, and we run the same source-by-source check against it. We look for the documentation defects an EU inspector finds most often, and we return them to you in plain language. Some sections lean hardest on qualified judgement, and those are the ones we flag most carefully; a finished SDS must be compiled by a competent person under REACH, and the free SDS audit tells you where the sheet you have would fall short of that.
We cannot promise a shipment clears customs — nobody honestly can. What we do is tell you whether the sheet you have would pass the EU border document check, and remove the documentation defects inspectors find most often before your goods reach the border.
You can also verify the method before you ask us anything: open any product page and expand the safety sections. Beside every value you will see its status and its source. Then send us your own SDS and we will do the same for it.
Proof, not promises. Be sceptical of anyone who hands you a green tick without the source beside it.
Who runs this
This catalogue is a working demo of the MOL-GOD chemical-commerce platform. It is operated by Nonsensia Ltd, Company No. 15165427, London, United Kingdom. The United Kingdom is outside the EU — we state that plainly, as we state everything else. The free SDS audit is the fastest way to see how we work — free, as a first step, not a priced service — before any paid engagement.
Send us the SDS you already have
Send us the SDS you already have and your destination country. Within 48 hours we return a nine-point report of what an EU inspector would most likely flag. Free — you pay nothing to see it.
