Last updated: April 2026 dataTris(2,3-dibromopropyl) phosphate — commonly known as TRIS — is a brominated flame retardant that has been banned from use in children's sleepwear in the United States since the late 1970s due to its carcinogenicity, yet it remains a traded industrial chemical intermediate under HTS 2919100000. Taiwan leads US import supply, followed by China and Germany. Importers should be aware that end-use restrictions under the Consumer Product Safety Act apply to articles treated with this compound, and any downstream application in consumer goods warrants careful legal review.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The chemical itself is not banned from importation as a bulk substance, but its use in children's sleepwear and certain consumer articles is prohibited under CPSC regulations. Importers of articles treated with or containing TRIS should conduct a thorough end-use compliance review before entry. Industrial or laboratory uses may be permissible, but any consumer-product application requires legal counsel familiar with CPSC requirements.
Taiwan has a well-developed specialty organophosphorus and flame-retardant chemical industry that supplies industrial and export markets globally. The compound retains legitimate industrial uses — for example, as an intermediate in certain chemical syntheses — that sustain trade flows independent of its consumer-product restrictions. Supply from Taiwan also reflects established trade relationships in the broader phosphate ester chemical sector.
