Tea grades explained: CTC (BP1, PF1, PD, D1) and orthodox (OP, FOP, BOP), and how auctions set prices
Tea grade names describe the size of the leaf particles, not the quality alone. This guide explains the common CTC and orthodox grades and how the main auctions set tea prices.

CTC and orthodox
CTC (crush, tear, curl) tea is cut into small, even granules that brew strong and fast, which suits tea bags. Orthodox tea is rolled, so the leaf stays larger and the cup is lighter and more complex.
Common CTC grades
| Grade | Meaning | Typical use |
|---|---|---|
| BP1 | Broken Pekoe 1: larger, round granules | Loose tea and blends |
| PF1 | Pekoe Fannings 1: fine, even granules | Tea bags |
| PD | Pekoe Dust: smaller particles, strong liquor | Tea bags |
| D1 | Dust 1: very fine particles | Strong tea bags and bulk blends |
| Secondary grades (FNGS, BMF, Dust) | Fannings, broken mixed fannings, dust | Low-cost blends |
Common orthodox grades
- OP (Orange Pekoe): long, wiry whole leaves.
- FOP (Flowery Orange Pekoe): whole leaf with some tips.
- BOP (Broken Orange Pekoe): broken leaf, a stronger cup.
- Extra letters such as T (tippy) and G (golden) describe more tips, for example TGFOP.
How auctions set prices
At the Mombasa, Colombo and Indian auctions, buyers taste each lot and bid on the sample. Price depends on the grade, the look of the leaf, the colour and strength of the liquor, the season and demand from big markets. Prices are usually quoted in US dollars per kg (Mombasa) or local currency per kg.
The World Bank publishes a monthly tea price as the average of the Kolkata, Colombo and Mombasa auctions. On Coffee Parchment, see tea lots or tea origins like Kenya.
Frequently asked questions
Is BP1 better than PF1?

What does CTC mean?
Crush, tear, curl: a way of processing black tea into small granules that brew quickly.
Where can I see tea prices?
Auction organisers and tea boards publish weekly results, and the World Bank publishes a monthly average of three auctions.
