Do you provide free samples for evaluation?

Yes — samples are free of charge; the buyer covers freight (freight collect). Standard evaluation samples are 5–10 g, sufficient for GC-MS and perfumery trials.

Each sample is drawn from a current production batch, so what you evaluate is what you will receive in bulk — no 'golden sample' switching. The sealed vial plus GC-MS trace lets your lab verify composition before you commit a PO.

Send your company details, courier account (DHL/FedEx/UPS) or billing preference, and delivery address, and we will dispatch the sample within 48 hours.
