Last updated: August 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.

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.
