Six-stage verification from supplier to batch register.
Supplier Identification
Suppliers are identified through published research literature and third-party ingredient directories. Initial evaluation covers the supplier's documentation chain: country of origin certificates, processing method records, and food-grade facility registration.
Documentation Audit
Before any ingredient enters the Karoven formulation register, the sourcing analyst reviews the supplier's certificate of composition and chain-of-custody documentation. Incomplete documentation results in automatic exclusion from consideration.
Sample Submission
Approved supplier samples are submitted to an independent laboratory. Active ingredient concentrations are measured using standard analytical methods appropriate to each compound — for example, HPLC for plant extract quantification.
Compositional Analysis
Laboratory results are cross-referenced against the labelled profile. Any result falling outside a 5% variance range triggers a formal query to the supplier and re-submission. Only batches within tolerance proceed to the formulation stage.
Batch Coding & Register Entry
Each verified batch receives a unique batch code. The code is entered into the Karoven batch register along with the laboratory result summary, production date, and supplier reference. Register entries are published quarterly.
Subscriber Transparency Report
Registered Karoven subscribers receive a quarterly batch report covering all active formulations. The report includes batch codes, laboratory variance summaries, and any sourcing changes made in the reporting period.
The Karoven batch register is updated in Q1, Q2, Q3, and Q4 of each production year. Subscribers receive email notification when each update is published. Archived register entries remain available for review.
