Indian Tea Standards: Tea Board Certification, GI Protection, and Grading

India is the world’s second-largest tea producer and home to some of the most iconic tea varieties - Darjeeling, Assam, and Nilgiri. The Indian tea regulatory system is managed primarily by the Tea Board of India, a statutory body under the Ministry of Commerce and Industry, Government of India.

Tea Board of India

Established in 1954 under the Tea Act, the Tea Board of India is the apex body regulating the Indian tea industry. Its responsibilities include:

  • Quality control and certification of Indian tea
  • Registration of tea estates, factories, and buyers
  • Management of tea auctions across India
  • Promotion of Indian tea domestically and internationally
  • Research and development support
  • Welfare schemes for tea workers
  • Regulation of tea exports and import of tea into India

The Tea Board has its headquarters in Kolkata and regional offices in major tea-producing regions including Assam, Darjeeling, Dooars, Terai, Nilgiris, and Kerala.

Tea Grading System in India

Indian tea follows a detailed leaf grade system, particularly for black tea (which accounts for ~98% of Indian tea production). The grading is based on leaf size, appearance, and quality characteristics.

Whole Leaf Grades

  • SFTGFOP1 (Super Fine Tippy Golden Flowery Orange Pekoe 1): Highest grade of whole leaf tea. Long, wiry leaves with abundant golden tips. Exceptional quality, primarily from Darjeeling and high-altitude estates
  • FTGFOP (Fine Tippy Golden Flowery Orange Pekoe): Very high quality whole leaf with golden tips. Excellent flavor and aroma
  • TGFOP (Tippy Golden Flowery Orange Pekoe): High-quality whole leaf with visible golden tips. Good flavor complexity
  • GFOP (Golden Flowery Orange Pekoe): Whole leaf tea with some golden tips. Good quality
  • FOP (Flowery Orange Pekoe): Standard whole leaf grade. Whole leaves with some bud content
  • OP (Orange Pekoe): Basic whole leaf grade. Uniform whole leaves, minimal tips
  • OPA (Orange Pekoe A): Slightly larger leaf than OP, bolder flavor

Broken Leaf Grades

  • FTGBOP (Fine Tippy Golden Broken Orange Pekoe): Highest broken grade with golden tips
  • TGBOP (Tippy Golden Broken Orange Pekoe): High-quality broken leaf with golden tips
  • GBOP (Golden Broken Orange Pekoe): Broken leaf with some golden tips
  • BOP (Broken Orange Pekoe): Standard broken leaf grade. Most common in tea bags
  • BP (Broken Pekoe): Smaller broken leaves
  • OF (Orange Fannings): Fine particles, smaller than BP
  • PF (Pekoe Fannings): Even finer particles
  • Dust grades (D1, D2, etc.): Finest particles, used in tea bags and instant tea

Note: “Orange Pekoe” does NOT refer to orange flavor - it’s a grade term describing leaf size and style, derived from the Dutch House of Orange-Nassau.

Darjeeling GI Protection

Darjeeling tea is India’s most famous GI-protected product, often called the “Champagne of Teas.” The Darjeeling GI status was granted under the Geographical Indications of Goods (Registration and Protection) Act, 1999.

Darjeeling GI Requirements:

  • Protected area: 87 tea estates in the Darjeeling hills of West Bengal, covering approximately 17,500 hectares
  • Altitude: Tea must be grown at elevations between 600m and 2,000m above sea level
  • Cultivars: Primarily China jat (variety), with some Assam jat and clones
  • Processing: Must be processed within the designated geographical area following traditional methods
  • Flushes: Three main harvest seasons - First Flush (March-May), Second Flush (May-June), and Autumnal (October-November)
  • Darjeeling logo: Only certified Darjeeling tea may carry the official Darjeeling logo and wordmark
  • Tea Board certification: The Tea Board of India inspects and certifies all Darjeeling tea for authenticity

The Tea Board has been aggressive in enforcing Darjeeling GI protection internationally, pursuing legal action against counterfeit “Darjeeling” teas sold in other countries.

Assam Tea and GI Status

Assam produces more than 50% of India’s total tea. Assam tea received GI status in 2007:

  • Protected area: Entire state of Assam, both the Brahmaputra Valley and Barak Valley
  • Characteristics: Bold, malty, full-bodied black tea with distinctive “Assam briskness”
  • Cultivar: Assam jat (Camellia sinensis var. assamica) - the large-leaf variety native to the region
  • Production: Almost entirely CTC (Crush, Tear, Curl) method for strong, consistent tea ideal for breakfast blends
  • Harvest seasons: First flush (March-April), Second flush (May-June), Monsoon flush (July-September), Autumn flush (October-November)

Nilgiri Tea

Nilgiri (Blue Mountains) tea from Tamil Nadu also has GI status:

  • Protected area: Nilgiris district and surrounding areas of Tamil Nadu, Karnataka, and Kerala
  • Characteristics: Bright, fragrant, medium-bodied tea with floral notes. Grown at elevations of 1,000-2,500m
  • Unique feature: Only tea region in the world with two production peaks (December-January and June-July) due to unique climatic conditions

Food Safety and Quality Standards

FSSAI - Food Safety and Standards Authority of India

The FSSAI, under the Ministry of Health and Family Welfare, sets food safety standards for all food products in India including tea:

  • Moisture content: Maximum 8% for black tea
  • Total ash: Maximum 8%
  • Water-soluble ash: Minimum 45% of total ash
  • Water extract: Minimum 30%
  • Crude fiber: Maximum 17%
  • Pesticide residues: MRLs specified under the Food Safety and Standards (Contaminants, Toxins and Residues) Regulations, 2011

Tea Board Quality Control

The Tea Board operates quality control measures including:

  • Mandatory quality inspection of tea sold at auctions
  • Licensing of tea factories and warehouses
  • Regular testing of tea for adulteration and contamination
  • Export quality inspection and certification
  • Laboratory testing facilities in major tea regions

Tea Auction System

India has a well-established tea auction system, which is the primary channel for tea trade. Major auction centers include:

  • Kolkata Auction Centre: Largest in India, handling North Indian teas (Assam, Dooars, Darjeeling)
  • Guwahati Auction Centre: Handles Assam teas
  • Siliguri Auction Centre: Handles Dooars, Terai, and Darjeeling teas
  • Cochin Auction Centre: Handles South Indian teas (Nilgiri, Kerala)
  • Coonoor Auction Centre: Nilgiri tea auction

Tea sold at auctions must meet minimum quality standards set by the Tea Board. Each lot is cataloged with grade, estate, garden, and other details.

Organic Tea in India

India has a growing organic tea sector, certified under the National Programme for Organic Production (NPOP) managed by APEDA (Agricultural and Processed Food Products Export Development Authority).

Indian organic tea is also certified under international standards for export markets including EU Organic, USDA Organic, and JAS. Major organic tea producing regions include parts of Darjeeling, Assam, and the Nilgiris.

The Indian tea standards system ensures that Indian teas are consistently graded, authentically labeled, and meet both domestic and international quality requirements - essential for maintaining India’s position as a global tea leader.
