Carbonyl Sulfide from United States
Carbonyl sulfide (COS) is a colorless, poisonous gas used as a pesticide fumigant and chemical intermediate. It is classified under tariff item 2811.19.00 as an 'other inorganic oxygen compound of non-metals' because Chapter 28 Note 2 specifically lists carbon oxysulphide as classifiable in this chapter.
