# HS code 2934.20: Compounds containing in the structure a benzothiazole ring- system (whether or not hydrogenated), not further fused

> HS code 2934.20 covers compounds containing in the structure a benzothiazole ring- system (whether or not hydrogenated), not further fused. It sits in heading 29.34 (nucleic acids and their salts, whether or not chemically defined; other heterocyclic compounds) in chapter 29 (organic chemicals). Other goods of heading 29.34 are classified under 2934.10 (compounds containing an unfused thiazole ring (whether or not hydrogenated) in the structure), 2934.30 (compounds containing in the structure a phenothiazine ring- system (whether or not hydrogenated), not further fused), 2934.91 (other, aminorex (INN), brotizolam (INN), clotiazepam (INN), cloxazolam (INN), dextromoramide (INN), haloxazolam (INN), ketazolam (INN), mesocarb (INN), oxazolam (INN), pemoline (INN), phendimetrazine (INN), phenmetrazine (INN) and sufentanil (INN); salts thereof), 2934.92 (other, other fentanyls or their derivatives) and 1 other.

## How it is structured

2934.20 is a six-digit subheading. Its first two digits, 29, are the chapter; the first four, 2934, are heading 29.34; the last two, 20, identify the subheading within the heading.

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

- Chapter 29: Organic chemicals
- Heading 29.34: Nucleic acids and their salts, whether or not chemically defined; other heterocyclic compounds
- Subheading 2934.20: Compounds containing in the structure a benzothiazole ring- system (whether or not hydrogenated), not further fused

## In other countries

No national tariff lines under 2934.20 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 2934.20 at six digits and add their own digits after it.

- Previous subheading: [2934.10](https://staging.border.bot/hs-codes/293410) Compounds containing an unfused thiazole ring (whether or not hydrogenated) in the structure
- Next subheading: [2934.30](https://staging.border.bot/hs-codes/293430) Compounds containing in the structure a phenothiazine ring- system (whether or not hydrogenated), not further fused
