Quality Reports
Every shipment ships with independent laboratory verification — recent reports are summarised below.
Independent lab verification
Premium Vertex never self-tests. Every consignment is sampled at origin by an independent surveyor and tested in an ISO 17025 accredited laboratory. The summaries below are drawn from recent live shipments — full reports are available to buyers on request.
Our quality process
Four checkpoints from origin sampling to destination retest.
Origin sampling
Pre-shipment samples drawn at the refinery or crusher under independent surveyor supervision.
Lab testing
Accredited labs (SGS, BV, Intertek) test every consignment against the contracted specification.
Sealed shipment
Tank seals, lot numbers, and sample retains travel with the consignment for traceability.
Destination retest
Shore-tank sampling at discharge — any variance triggers our quality-guarantee replacement clause.
