Protocol C — Lot-Level Safety Signals (Minimum practical checks)
Minimum: lot ID + label clarity + COA when available.
Safety is not a marketing claim. It is basic responsibility.
This section is intentionally minimal and realistic for small teams.
C1. Lot ID and trace continuity
Ask
- Is there a lot ID / production code?
- Can the supplier identify the batch?
Verify
- Lot ID exists on packaging or invoice
Record
- Lot ID + receiving date
- Use-by or best-by date
C2. Labeling clarity (for resale or service)
Ask
- Does the label clearly indicate matcha use category?
- Any allergen handling or shared facility notes?
Verify
- Packaging label + supplier documentation
Record
- Photos of label
- Any notes relevant to customers (non-medical)
C3. When COA is not available
Verify
- Lot ID (label or invoice)
- Best-by / use-by date
- Basic handling is possible (dry tools / sealed / no steam / no return)
Record
- Label photo
- Lot ID + receiving date
- Best-by / use-by date
- Opening date
