Publishing a request
A purchase request is your structured demand for a chemical product or supply need. Publishing one lets relevant suppliers discover and respond to it.
You can create a request in two ways:
- Without an account — use the homepage quick form or the "Post a purchase request" entry in the navigation. A product name and an email address are enough, and it takes about two minutes.
- With an account — sign in, open your workspace, and start a new purchase request. You can also start from a compound page to prefill the product details.
Anonymous requests are still private by default: contact details are exchanged only after both sides confirm interest. The public demand board shows only anonymized requests — chemical identity, volume range, destination market, and posting date — never your name, company, or contact details. Requests are screened against the chemical regulatory lists; chemicals on CWC schedules and controlled precursor lists cannot be published — the content screening and compliance policy describes how screening works.
Fields that improve matching
The more precise your request, the better the matches:
- CAS number — strongly recommended. It helps ensure accurate matching to the right compound instead of a similarly named one.
- Purchase volume band — helps suppliers judge fit and respond faster.
- Destination country/region — decides your reach: the same request can target domestic, regional, or global suppliers.
- Specifications and use — purity, grade, packaging, and intended use where relevant.
You can post in any of the 11 supported languages; matching works across languages, and adding the English product name or CAS number improves match precision further.
Managing an anonymous request
After you publish without an account, ChemAbout sends a management link to the email you provided. Keep that link safe. It lets you:
- View the request you posted.
- Unlist it from the public demand board while keeping private matching active.
- Show it on the public demand board again.
- Extend an expired request.
- Delete the request so it no longer appears or participates in matching.
The management link acts like a private key for that request, so do not share it with people who should not be able to change or delete the request.
What happens next
Published requests are matched against supplier products on ChemAbout, and suppliers whose products match are notified of the request by email. When a supplier responds and signals intent to supply, ChemAbout notifies you by email — for anonymous requests the email carries the response itself, including the supplier's contact details, so both sides can continue directly.
If you have an account, matches you accept become matched requests, managed inside your workspace. If you posted as a guest, ChemAbout uses your email and management link to help you keep control of the request.
Remember: ChemAbout connects you with potential counterparts. Supplier qualification, contracts, payment, shipping, and compliance remain your responsibility — see What ChemAbout is (and is not).
