HTS heading 2827 is a broad product category for certain inorganic halogen compounds. It groups chlorides, chloride oxides, chloride hydroxides, bromides, bromide oxides, iodides, and iodide oxides—generally substances made by combining chlorine, bromine, or iodine with another element or chemical group. The heading covers chemical identity, not simply any product that contains one of these elements.
To reach a specific 8-digit HTS code, first identify the compound’s exact chemical composition and then follow the heading’s subheadings and statistical provisions. The relevant distinction may be the particular material or chemical type, such as which metal or element is combined with the halogen, and sometimes the product’s stated form or other description. The complete 8-digit code must match the wording of the applicable subheading, along with any section, chapter, or legal notes.
What to check
- Confirm the product’s exact chemical name, formula, and CAS Registry Number from the safety data sheet, specification sheet, or manufacturer documentation.
- Determine whether the substance is a chloride, chloride oxide, chloride hydroxide, bromide, bromide oxide, iodide, or iodide oxide before comparing subheadings.
- Read every subordinate heading and applicable legal note under heading 2827; do not choose a code based only on a familiar product name or marketing description.
- Check whether the HTS text distinguishes the compound by the element or metal combined with the halogen, and match that description precisely.
- Have a customs broker or classification professional review difficult cases, mixtures, solutions, preparations, or products whose chemical identity is unclear.
HTS heading 2827 summary
Chlorides is a 4-digit product category containing 2 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.

Common questions
What products fall under HTS heading 2827?
Chlorides, chloride oxides and chloride hydroxides; bromides and bromide oxides; iodides and iodide oxides. To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
Start from the sub-categories (typically divided by material—for example cotton versus man-made fibers), then open the active 8- or 10-digit code that matches the product. When unsure, a licensed customs broker or a CBP binding ruling can confirm the classification.
