# Schemes

> The scheme enum of the ScripX API: RODTEP and ROSCTL duty credit scrip schemes, what each covers, who earns them, and the primary government sources for scheme rules.

Every endpoint that takes or returns a `scheme` uses one of exactly two values.

## The `scheme` enum

| Value    | Full name                                          | Covers                                                          |
| -------- | -------------------------------------------------- | --------------------------------------------------------------- |
| `RODTEP` | Remission of Duties and Taxes on Exported Products | Embedded central, state and local duties on most exported goods |
| `ROSCTL` | Rebate of State and Central Taxes and Levies       | Apparel, garments and made-ups (Chapters 61, 62, 63)            |

Both issue **duty credit scrips**: transferable credits that pay basic customs duty at face value. Credits transfer whole, carry a validity window, and are extinguished on utilisation.

## Practical differences for a trading desk

* **Liquidity.** RODTEP is the broader scheme and the deeper market; ROSCTL flow is concentrated in textile exporters.
* **Pricing.** Each scheme is priced independently; always read [`GET /v1/market/{scheme}`](/api-reference/trading/market) per scheme rather than assuming parity.
