Buyer Protection

Sorting and pricing rules

Prices are shown in the offer currency and converted to your display currency using a daily reference rate; the unit price is recalculated from the pack size.

The "Best" badge marks the lowest unit price among priced offers shown, after currency conversion.

Platform-operated (self-operated) suppliers are labelled on the supplier page and in every offer row.

Verified suppliers

Suppliers marked with a verification badge have been reviewed by us before their listings went live. The badge is shown on the supplier profile and in the offer table.

Verification is not a guarantee of any specific product, price or delivery performance. Always confirm product information and terms with the supplier.

Data accuracy

Chemical data is reference material compiled from public sources and may contain errors. We correct errors that are reported and confirmed. Before purchasing or using the data for a regulatory filing, please verify CAS numbers, formulae and hazard data against the supplier’s documentation.

How to raise a concern

If a listing looks wrong, a price seems off, or an inquiry has gone unanswered, contact us through the contact page. We aim to reply within two working days.
