Countries add their own digits after these six for their national tariff lines.

- Chapter 29: Organic chemicals
- Heading 29.08: Halogenated, sulphonated, nitrated or nitrosated derivatives of phenols or phenol-alcohols
- Within the heading: Derivatives containing only halogen substituents and their salts
- Subheading 2908.11: Pentachlorophenol (ISO)

## In other countries

No national tariff lines under 2908.11 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 2908.11 at six digits and add their own digits after it.
