Standard: Clean Tea Standard

What This Standard Solves

The global tea market widely relies on mixed-source supply chains,
where raw materials are aggregated from multiple regions,
processed in bulk, and redistributed without full traceability.

In such systems:

• origin becomes non-verifiable
• handling conditions are inconsistent
• contamination risk increases across the supply chain

Final packaging does not reflect actual product integrity.

Core Problem

Tea quality is not determined by final packaging.

It is determined by how the material is handled
throughout its entire lifecycle.

This includes:

• harvesting conditions
• contact materials
• drying methods
• storage and transport
• processing environment

If integrity is lost at any stage, it cannot be restored later.

Supply Chain Integrity Risk

Mixed and industrial tea systems often involve:

• aggregation from multiple unknown sources
• storage in plastic containers or bags
• drying on synthetic or contaminated surfaces
• uncontrolled exposure to environmental factors
• lack of handling standards at origin

These conditions create:

• contamination risk
• loss of purity
• non-transparent product origin

Handling Principle

High-quality tea cannot be treated as bulk raw material.

If tea is handled as low-value mass input,
its integrity is compromised regardless of final presentation.

Proper handling requires:

• non-plastic contact materials
• controlled harvesting methods
• clean and natural drying conditions
• separation of batches and origin

Material Contact Integrity

Throughout the process, tea must avoid:

• plastic contact during harvesting, drying, storage, or transport
• synthetic surfaces that may release contaminants
• uncontrolled industrial environments

Preferred conditions include:

• natural materials (e.g. bamboo, wood, cotton)
• breathable and non-reactive surfaces
• clean, controlled environments

Harvesting Integrity

To achieve high-quality tea:

• harvesting must be selective and controlled
• tools and containers must not introduce contamination
• handling must preserve plant integrity

Improper harvesting practices degrade quality at the source.

Processing Integrity

Drying and processing must ensure:

• no contamination from surfaces
• no chemical intervention
• preservation of natural composition

The process must maintain the original quality of the plant material.

Core Principle

Product integrity is defined by the weakest point in the supply chain.

Final packaging does not determine quality.
Handling throughout the lifecycle does.

Why This Standard Exists

The market currently lacks a clear distinction between:

• visually premium products
• structurally clean products

This standard establishes:

• traceable origin conditions
• handling integrity requirements
• material contact rules
• lifecycle-based quality definition

One-Line Definition

Tea is only as clean as its full journey
from harvest to consumption.
