How to choose the right subheading
- Identify whether the product is hydrogen chloride or chlorosulfuric acid.
- For hydrogen chloride, use 2806.10.00.00 whether it is gas or an aqueous hydrochloric acid solution.
- For chlorosulfuric acid, use 2806.20.00.00.
- Do not decide by end use such as pH reduction, cleaning, or sulfonation.
- Confirm the product is not a mixture, salt, or other acid.
Often confused with
- Heading 2815Sodium hydroxide (caustic soda)
It is an alkali hydroxide, not an acid.
- Heading 2809Phosphoric acid
It is a different inorganic acid with its own heading.
- Heading 2811Hydrofluoric acid
It is another inorganic acid classified outside heading 2806.
- Heading 2828Sodium hypochlorite bleach
It is a hypochlorite, not hydrogen chloride or chlorosulfuric acid.
- Heading 2827Calcium chloride
It is a chloride salt, not hydrogen chloride acid.
