## Common ground
All options refer to devices that distribute water via spray or sprinkling for irrigation, recreation, or control purposes.
## Options at a glance
**3924.90 – Plastic-only**
- **Defining trait:** Made primarily of plastic with no moving parts; operates solely by water pressure.
- **Typical examples:** Simple fixed-head lawn sprinklers, pop-up sprinkler heads.
- **Best fit when:** The product is entirely plastic and relies only on water pressure to function.
**7418.10 – Copper-only**
- **Defining trait:** Made mainly of copper with no mechanical components; operates by water pressure alone.
- **Typical examples:** Copper-based irrigation sprinklers used in high-durability settings.
- **Best fit when:** The product is made primarily of copper and has no moving parts.
**7615.10 – Aluminium-only**
- **Defining trait:** Made mainly of aluminium with no mechanical components; operates by water pressure only.
- **Typical examples:** Lightweight, corrosion-resistant sprinklers for outdoor use.
- **Best fit when:** The product is made primarily of aluminium and functions without moving parts.
**8424.82 – Agricultural mechanical**
- **Defining trait:** Contains mechanical components (e.g., rotating heads, timers) and is used in agriculture/horticulture.
- **Typical examples:** Rotating sprinklers with gears or motion-activated systems for farms.
- **Best fit when:** The device has moving parts and is intended for farming or gardening.
**8424.89 – Non-agricultural mechanical**
- **Defining trait:** Has mechanical components but is not used in agriculture/horticulture.
- **Typical examples:** Mechanical sprinklers for parks, sports fields, or industrial sites.
- **Best fit when:** The device has moving parts and serves non-farming purposes.
**8481.80 – Valve-integrated**
- **Defining trait:** Includes a built-in valve to control water flow directly from the sprinkler.
- **Typical examples:** Sprinklers with on/off valves or flow regulators.
- **Best fit when:** The product has an integrated valve mechanism.
**9107.00 – Timed controllers**
- **Defining trait:** Electronic timers that control when and how long sprinklers operate.
- **Typical examples:** Smart irrigation timers for lawns or orchards.
- **Best fit when:** The device is a controller, not a sprinkler itself.
**9503.00 – Inflatable play sprinklers**
- **Defining trait:** Designed for children’s outdoor water play; inflatable and non-irrigation.
- **Typical examples:** Water-squirting toys shaped like animals or funnels.
- **Best fit when:** The product is for recreation, not irrigation.

## How to choose
- Is the device made of plastic, copper, or aluminium? → Choose 3924.90 / 7418.10 / 7615.10
- Does it have moving parts (e.g., rotating head)? → HS Code 8424.82 or 8424.89
- Does it include a built-in valve? → HS Code 8481.80
- Is it used for farming/gardening? → HS Code 8424.82
- Is it a timer/controller? → HS Code 9107.00
- Is it for children’s play? → HS Code 9503.00
## Overlaps & pitfalls
- A sprinkler with a valve and mechanical parts could fit both 8424.82 and 8481.80. Choose based on **main function**: if it's about motion, use 8424.82; if flow control is key, use 8481.80.
- Timers (9107.00) are not sprinklers themselves—confusion may arise if the product includes both a controller and sprinklers.
- No priority rule is implied; users should select based on **primary function**
