Chemical Disposal Checker
Look up a chemical name or CAS number, then talk to us about collection. If the label is missing or the contents are uncertain, we can help arrange the assessment.

How can we help?
Complete the form and we will get back to you.
What the checker can tell you
Search a name, synonym or CAS number to see the listed substance hazards. Match the entry to the label where you can. A substance record alone does not classify a waste mixture or confirm a disposal route.
Unknown or mixed chemicals
Contact us with the approximate quantity, container type and anything you know about the contents. We can arrange assessment and any sampling or testing needed. Keep unknown materials separate; do not open or mix them to find out what they are.
Waste classification and paperwork
The process that produced the waste, its composition and hazardous properties affect classification. We can help establish the information needed for the appropriate waste code and collection paperwork. The checker is a starting point for that work.
Arranging a collection
Tell us the site postcode, what needs removing and any access restrictions. Labels, photographs and safety data sheets are useful if available. You can enquire before you have a complete set of documents.
Chemical disposal questions
Can I contact you without completing the tool?
No label or safety data sheet? Tell us what you know. We can arrange the checks needed to plan collection. You can enquire directly; completing the tool is optional.
Does this give a formal hazardous waste classification?
No. It shows source hazard information and hazardous properties that may need assessment. Waste classification depends on the applicable waste code, composition and hazardous-property assessment under WM3, with sampling or testing where appropriate.
Can I check a branded cleaner or chemical mixture?
You can search a named constituent from its safety data sheet, but the result applies only to that entry. The checker does not classify the branded product, its dilution or the resulting waste mixture.
Does a small quantity avoid hazardous waste controls?
A small quantity is not automatically non-hazardous. Classification depends on the waste and its properties, not simply the amount held. Give the approximate quantity so the collection arrangements can be checked.
What if the bottle has no readable label?
Treat the identity as unknown. Do not identify it from colour or smell. Record where it came from, any stock records and any readable markings, and explain the uncertainty before collection is arranged.
How current are the chemical records?
The HSE source page was checked on 13 September 2026. The checker uses a dated copy of the published data, not a live legal update service. Use the source link to check HSE's current list; results retain the entry dates and notes supplied in the dataset.

Contains public sector information licensed under the Open Government Licence v3.0. HSE is the source for the GB MCL classification entries; WM3 is the source for the waste-assessment guidance cited here. We provide the search interface and explanatory summaries. Identity-only records retain their original reference links. No result is an authorisation for treatment, transport or disposal. The identity reference combines ILO/WHO International Chemical Safety Card identity facts with HSE names and identifiers. It does not reproduce the ICSC safety-card prose or convert it into a waste verdict.
