🏛️ Siliguri (STAC) & Guwahati (GTAC) Tea Auction Ecosystem
The North Indian tea trade is anchored by two premier public auction hubs operating under the regulatory supervision of the Tea Board of India: the Siliguri Tea Auction Committee (STAC) in West Bengal and the Guwahati Tea Auction Centre (GTAC) in Assam. Together, these trading corridors handle over 400 million kilograms of premium CTC (Crush, Tear, Curl), Orthodox, and Green teas annually, serving domestic packet tea blenders, wholesale distributors, regional tea packeters, and international exporters.
📍 Siliguri Tea Auction Centre (STAC)
Strategically situated at the trade crossroads of North Bengal, STAC is the definitive price-discovery platform for Dooars, Terai, and Darjeeling tea estates.
📍 Guwahati Tea Auction Centre (GTAC)
Recognized as the world's largest auction venue for CTC teas by volume, GTAC benchmarks prime Upper Assam, Central Assam, and Barak Valley (Cachar) estates.

🍃 North Indian CTC Tea Grade Classification: Leaf vs Dust Categories
In North Indian commercial tea trading, auction catalogues categorize manufactured CTC teas strictly into Leaf Category and Dust Category based on mechanical sifting mesh sizes, liquor density, color extraction rate, and retail blend utilization:

|---|---|---|---|
| LEAF CATEGORY (Grades BOPL, BP, OF, PF) |
BOPL Broken Orange Pekoe Large |
Coarse, bold leaf cut with clean blackish-brown appearance. Delivers bright, gentle liquor with nuanced aroma. | Premium whole-leaf blends, specialty single-estate retail offerings, and mild European infusions. |

The principal backbone grade of North Indian packet blends. Granular, bold particle size with bright reddish-amber cup and rich malty body. | Leading national and regional packet brands (e.g. Tata Tea, Wagh Bakri, Byahut Gold). | |

Medium-small flat particle cut. Rapid infusion, brisk mouthfeel, sparkling color, and balanced astringency. | Household premium blends, chai blends demanding quick brewing, and restaurant tea blends. | |
