How it works

A kilogram is not a comparable unit by itself. Price needs product state and commercial context.

Observe

Collect eligible evidence: public-market retail observations now, verified arm's-length transactions in the pre-launch reference.

Classify

Resolve product identity, product state, commercial lane and evidence quality. Marketing descriptors are separated from biological classification.

Normalize

Control for pack size, quantity, geography, currency, taxes, logistics, quality and other validated comparability variables.

Test

Apply sufficiency, diversity, anomaly, related-party and publication controls.

Publish

Release an aggregated historical reference with methodology version, data window and uncertainty or context. Never a naked number.

Public Retail Monitor

Evidence: public retail asking prices. Lane: retail / public asking. Available now, clearly labelled.

Verified Market Reference

Evidence: verified arm's-length transactions with corroboration. Multiple commercial lanes. Pre-launch.

A reference is not a recommendation. It describes historical observed market context. A seller remains free to set its price; a buyer remains free to negotiate. Brand, service, scarcity and presentation may legitimately create different prices.

Cavport publishes historical market context and public-market observations. It does not set or recommend prices, provide appraisals, determine customs value or make legal findings. Public Retail Monitor figures are based on public retail asking prices observed on a defined date and are separate from Cavport Verified References, which are pre-launch.
