HTS US: 2814.XX.XXXX
Description
This heading pertains to ammonia, a compound widely used in agriculture, chemical manufacturing, refrigeration, and other industrial applications. The classification includes two main forms of ammonia:
- Anhydrous ammonia: Pure ammonia in its gaseous or liquid form without any water content, commonly used as a fertilizer or refrigerant.
- Ammonia in aqueous solution: Ammonia dissolved in water, often referred to as ammonium hydroxide or aqueous ammonia, utilized in cleaning agents, chemical synthesis, and other industrial processes.
Both forms are categorized under this heading and distinguished by their water content and physical state.
Code Hierarchy
- Section IV: Chemicals and Allied Industries (Chapters 28-38)
- Chapter 28: Inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes
- Heading 2814: Ammonia, anhydrous or in aqueous solution
- US HTS Code (10-digit):
2814.XX.XXXX– Specifies the exact form and concentration.
Detailed Breakdown of Subheadings
The 4-digit HS heading 2814 is further detailed into subheadings based on the physical state and composition of ammonia products.
| HTS Code | Description | Examples & Notes |
|---|---|---|
| 2814.10.00.00 | Anhydrous ammonia | Pure ammonia without water, typically stored and transported as a compressed liquid or gas. Widely used in fertilizer production, refrigeration systems, and chemical manufacturing. |
| 2814.20.00.00 | Ammonia in aqueous solution | Ammonia dissolved in water at various concentrations, commonly known as aqueous ammonia or ammonium hydroxide. Used in cleaning products, water treatment, and as a reagent in chemical processes. |
What is NOT Classified Here?
To prevent misclassification, consider the following:
- Other nitrogenous compounds: Compounds such as ammonium salts or urea are classified under different headings.
- Ammonia derivatives: Chemical derivatives or compounds containing ammonia but chemically altered are not included here.
- Mixtures with other chemicals: If ammonia is part of a mixture with other chemicals beyond aqueous solutions, other headings may apply.
Notes
- Safety Regulations: Due to its hazardous nature, the import and handling of anhydrous ammonia are strictly regulated under various environmental and safety laws.
- Duty Rates: Duty rates vary by the specific HTS code, with possible exemptions or reduced rates depending on trade agreements and end use.
- Labeling Requirements: Proper labeling and documentation are necessary to comply with U.S. Customs and environmental regulations.
