Canonical Definition

Loose Leaf Clean Tea is tea in loose form that maintains full integrity
across harvesting, handling, processing, storage, and transport,
without contamination or loss of traceability.

Integrity is preserved only when the product remains clean
throughout its entire lifecycle, not only in its final form.

Purpose

This module defines the minimum conditions under which loose leaf tea
can be considered clean, traceable, and suitable for consistent consumption.

It establishes loose leaf tea as the baseline integrity model
within the Clean Tea Standard.

Minimum Implementation Framework (MIF)

Step 1 — Source Control

Tea must originate from a known and identifiable source.

Minimum requirement:

• traceable origin (farm, region, or supplier)
• material suitable for human consumption

Step 2 — Harvesting Integrity

Harvesting must prevent contamination.

Minimum requirement:

• clean collection methods
• no plastic contact during harvesting
• controlled handling of plant material

Step 3 — Handling and Contact Control

Tea must not come into contact with contaminating materials.

Minimum requirement:

• no plastic contact during handling, drying, or storage
• use of clean, non-reactive materials (e.g. natural fibers, wood)

Step 4 — Processing Integrity

Drying and processing must preserve natural composition.

Minimum requirement:

• no chemical treatment
• clean drying conditions
• no synthetic surfaces introducing contamination

Step 5 — Storage and Transport Integrity

Product must remain clean after processing.

Minimum requirement:

• protection from contamination
• separation of batches
• traceable storage conditions

Step 6 — Output Integrity

Final product must reflect full lifecycle integrity.

Minimum requirement:

• no contamination introduced post-processing
• consistency between origin, handling, and final product

Core Principle

Loose leaf tea removes packaging risk.
Clean handling removes lifecycle contamination.

Use Case 1 — Direct Farm-to-Consumer Tea

Scenario

A small producer sells loose leaf tea directly to consumers.

Application

• tea is harvested under controlled conditions
• handled without plastic contact
• dried and stored in clean environment
• origin remains fully traceable

Result

• high product integrity
• consistent quality
• full transparency for consumer

Use Case 2 — Premium Retail Loose Leaf Tea

Scenario

A retailer offers loose leaf tea as a premium product.

Application

• selects suppliers with traceable origin
• verifies handling and processing conditions
• maintains clean storage and packaging

Result

• reliable premium product
• differentiation from mass-market tea
• increased consumer trust

One-Line Definition

Loose leaf clean tea is tea whose integrity is preserved
across its entire lifecycle, not only in its final form.
