Dibutyl phthalate (DBP) under K-REACH

C16H22O4 · 邻苯二甲酸二丁酯

Status: Registered. Dibutyl phthalate is registered under K-REACH. **Korea TCCA Toxic Chemicals list: DBP scheduling-potential (Repr. 1B classification)** (verify against the current TCCA Toxic Chemicals list at https://www.nics.go.kr/ https://www.nics.go.kr/ before relying). **Korean Special Act on the Safety of Children's Products + Korean Industrial Standard KS K 0125 (toy safety) restrict DBP + DEHP + BBP + DINP + DIDP + DNOP in children's toys + child-care articles at >0.1% by mass** (verify against current MoTIE + Korean Agency for Technology and Standards before relying). NO active Korean AD/CVD case on Chinese-origin DBP currently. KCFTA preferential zero-duty applies for Chinese-origin imports (subject to children's product overlay). **Korea is structurally a net-importer of DBP**; Chinese-origin import dependency dominant.

K-REACH treats dibutyl phthalate as a registered substance with **TCCA Toxic Chemicals Handling Permit overlay-potential + Korean Special Act on the Safety of Children's Products + KS K 0125 BAN at >0.1% by mass in toys + child-care articles**. KCFTA preferential zero-duty subject to children's product overlay. NO active Korean AD/CVD. **Korea structurally net-importer**; Chinese-origin import dependency dominant. **DBP distinguishing pattern across all 5 regimes**: Phthalate plasticiser produced by esterification of phthalic anhydride with n-butanol; major historical downstream uses were PVC plasticiser + cellulose-based film + nail polish + adhesives + sealants + coating-film-former + lubricants; **use in PVC progressively replaced by higher-molecular-weight phthalates (DEHP successor + DINP + DIDP) and non-phthalate plasticisers (DOTP + adipates + trimellitates) due to reproductive-toxicity classification**; **REACH Annex XIV authorisation list (added via Commission Regulation (EU) No 143/2011 of 17 February 2011, latest application date 21 August 2013, sunset date 21 February 2015) (sourced to EUR-Lex eli/reg/2011/143 + ECHA authorisation list)** is the most-restrictive overlay; **REACH SVHC candidate list (added 28 October 2008 as Repr. 1B) (sourced to ECHA candidate list)**; **REACH Annex XVII Restriction Entry 51 (DBP + DEHP + BBP + DIBP banned in toys + childcare + skin-contact consumer articles at >0.1% by mass effective 7 July 2020 via Commission Regulation (EU) 2018/2005) (sourced to EUR-Lex eli/reg/2018/2005)**; **EU Toy Safety Directive 2009/48/EC Annex II Part III (3) ban (sourced to EUR-Lex)**; **EU Cosmetic Products Regulation Annex II prohibition**; **Cal Prop 65 listing 2 December 2005 as developmental + female + male reproductive toxicant on the same date via NTP-CERHR Authoritative Bodies mechanism (sourced to OEHHA)**; **CPSIA 2008 BAN in children's toys + child-care articles at >0.1% by mass (sourced to 16 CFR 1307)**; **TSCA Section 6(b) Risk Evaluation finalized + Risk Management Rule in development (first 10 chemicals priority)**; **Australian Consumer Product Safety Mandatory Standard for phthalates restricts DBP at >0.1% by mass in toys + childcare**; **Korean Special Act on the Safety of Children's Products + KS K 0125 BAN at >0.1% by mass in toys + child-care articles**; **Chinese GB 24613-2009 toy phthalate BAN at >0.1% by mass + GB 4806.1-2016 + GB 9685-2016 food-contact material restrictions**; Repr. 1B H360Df + Aquatic Chronic 4 + suspected endocrine disruptor across all jurisdictions; OSHA + Korean MoEL + ACGIH + Safe Work Australia OEL 5 mg/m3 inhalable; NOT regulated as dangerous goods; **major non-Chinese producers ExxonMobil (USA Houston TX) + Eastman Chemical (USA Kingsport TN) + KH Neochem (Japan) + JSR (Japan)**; **China is the dominant global DBP producer + exporter** (Beijing Yanshan Petrochemical Sinopec + Anhui Yifeng + Hangzhou Hangwei + Jiangsu Pengrun + Shandong Hongxin Chemicals).

Restrictions and conditions of use

  • **Korean Special Act on the Safety of Children's Products + KS K 0125 BAN DBP at >0.1% by mass in toys + child-care articles**
