HTS US: 2992.XX.XXXX
Description
This heading encompasses hydrazine and hydroxylamine salts, which are inorganic chemical compounds widely employed in various industrial, agricultural, and chemical synthesis processes.
- Hydrazine salts: These are salts derived from hydrazine, typically used as reducing agents, in fuel cells, and in polymerization catalysis.
- Hydroxylamine salts: Salts of hydroxylamine, commonly utilized in pharmaceuticals, organic synthesis, and as intermediates in manufacturing.
The compounds covered under this heading are typically crystalline solids or powders, stable under normal handling conditions but may require careful storage due to their reactivity.
Code Hierarchy
- Section VI:
- Products of the Chemical or Allied Industries (Chapters 28-38)

Detailed Breakdown of Subheadings
While no specific sub-codes are listed in the current database for 2992, the heading generally covers a variety of hydrazine and hydroxylamine salts and related inorganic bases, which in practice are broken down by their chemical composition and usage.
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2992.10 | Hydrazine salts | Includes hydrazine sulfate, hydrazine hydrochloride, and related salts used in industrial applications. |
2992.10.0000 |
Specific hydrazine salt compounds classified here. | |
| 2992.20 | Hydroxylamine salts | Salts such as hydroxylamine hydrochloride, commonly applied in pharmaceutical manufacturing and organic synthesis. |

What is NOT Classified Here?
Important exclusions to avoid misclassification include:
- Organic hydrazine derivatives: Organic compounds containing hydrazine groups are classified under different headings in organic chemical chapters.
- Hydrazine free base: Pure hydrazine (free base) itself is classified separately, not under salt classifications.
- Other hydroxylamine derivatives: Complex organic hydroxylamine derivatives are classified elsewhere.
- Other inorganic bases: Some metal hydroxides and oxides not related to hydrazine or hydroxylamine salts are classified under other specific headings.
Notes
- Safety Regulations:
- Due to the reactive nature of hydrazine and hydroxylamine salts, importation and handling are subject to strict safety regulations and may require special permits or certifications.
- Duty Rates: Customs duty rates for these chemical compounds vary depending on the exact substance and use; consult current USHTS schedules for precise rates.
- Import Documentation: Detailed chemical composition and safety data sheets (SDS) are typically required for customs clearance.
