Last updated: August 2026 dataResidual phosphite esters and their halogenated, sulfonated, or nitrated derivatives not covered by the named subheadings fall here, entering under tariff line 2920290000. Singapore leads US import supply for this catch-all grouping, followed by Italy, India, and the United Kingdom — a geographically diverse supplier base that reflects the wide variety of specialty phosphorus compounds traded under this heading. Correct classification requires distinguishing these compounds from phosphate esters (heading 2919) and from the specifically named phosphites in subheadings 292021–292023, making chemical identity documentation essential.

Heading 2919 covers phosphoric acid esters (phosphates), while subheading 292029 covers esters of phosphorous acid (phosphites). The distinction turns on the oxidation state of phosphorus and the acid from which the ester is derived. Importers should provide CAS numbers and structural documentation to support the correct heading assignment.
Each chemically distinct compound in a mixed shipment must be classified separately. Named phosphites (292021, 292022, 292023) take precedence under their specific subheadings, while unlisted derivatives default to 292029. Separate line items on the commercial invoice with individual CAS numbers and quantities facilitate correct entry.
