Chloride oxides and chloride hydroxides have their own subheadings: copper chloride oxides and hydroxides fall under 282741, while those of other metals are captured by 282749. A compound that is purely a chloride without an oxide or hydroxide component would instead fall under the metal-specific chloride subheadings or the residual 282739.

Sodium and potassium bromides (282751) are used in pharmaceutical manufacturing, photographic chemicals, and oilfield completion fluids. Other bromides and bromide oxides (282759) serve flame-retardant and specialty chemical applications. The specific end use can affect whether any EPA or other regulatory review applies at import.
