Dibutyl phthalate (DBP) under IECSC

C16H22O4 · 邻苯二甲酸二丁酯

Status: Listed. Dibutyl phthalate is on IECSC as an existing chemical. **China is the dominant global producer of phthalates including DBP**; major Chinese DBP producers Beijing Yanshan Petrochemical (Sinopec) + Anhui Yifeng + Hangzhou Hangwei + Jiangsu Pengrun + Shandong Hongxin Chemicals; verify each producer-site pair against the producer's public website before relying. **GB 24613-2009 (Chinese national standard on toy phthalates) BANS DBP + DEHP + BBP in toys + childcare articles at >0.1% by mass**; **GB 4806.1-2016 + GB 9685-2016 (Chinese food-contact material standards) restrict DBP migration limit in food-contact plastics** (verify against current SAMR / NHC standards before relying). NOT on China Hazardous Chemicals Catalogue (2015 edition) at DBP level (verify against https://www.mem.gov.cn/ before relying). **Subject to multiple US + EU regulatory overlays on Chinese-origin DBP exports (Cal Prop 65 + CPSIA + TSCA Section 6(b) + REACH Annex XIV + Annex XVII + EU Toy Safety Directive)**; export consignment requires destination-specific compliance documentation.

IECSC treats dibutyl phthalate as a routine listed existing chemical with **GB 24613-2009 toy phthalate BAN + GB 4806.1-2016 + GB 9685-2016 food-contact material restrictions**. **China is the dominant global DBP producer + exporter**; export consignment subject to **multiple US + EU regulatory overlays (Cal Prop 65 + CPSIA + TSCA Section 6(b) + REACH Annex XIV authorisation + Annex XVII Restriction 51 + EU Toy Safety Directive)**. Major Chinese producers: Beijing Yanshan Petrochemical Sinopec + Anhui Yifeng + Hangzhou Hangwei + Jiangsu Pengrun + Shandong Hongxin Chemicals.

Listing and threshold

Substance Dibutyl phthalate (DBP) (CAS 84-74-2), C16H22O4
Regime China Inventory of Existing Chemical Substances (IECSC), administered by Ministry of Ecology and Environment (MEE)
Jurisdiction People's Republic of China

Tonnage threshold New Chemical Substance Notification (NCSN) under MEE Decree 12 not required (existing chemical)

Classifications under this regime

  • IECSC Listed Existing Chemical
  • GB 30000 GHS classification: Repr. 1B + Aquatic Chronic 4 (verify against current GB 30000-series at http://www.csres.com/ + http://www.std.samr.gov.cn/ before relying)
  • **GB 24613-2009 (Chinese national standard on toy phthalates) BANS DBP + DEHP + BBP in toys + childcare articles at >0.1% by mass** (verify against current SAMR standard before relying)
  • **GB 4806.1-2016 + GB 9685-2016 (Chinese food-contact material standards) restrict DBP migration limit** (verify against current SAMR / NHC standards before relying)
  • NOT on China Hazardous Chemicals Catalogue (2015 edition) at DBP level (verify against https://www.mem.gov.cn/ before relying)
  • JT/T 617 / GB 12268 hazardous-goods transport: NOT regulated as dangerous goods at solid / liquid form
  • **Subject to multiple US + EU regulatory overlays on Chinese-origin DBP exports (Cal Prop 65 + CPSIA + TSCA Section 6(b) + REACH Annex XIV + Annex XVII + EU Toy Safety Directive)**
  • IARC: Not classified (DBP not separately evaluated)

Restrictions and conditions of use

  • **GB 24613-2009 toy phthalate BAN: DBP at >0.1% by mass in toys + childcare articles**
  • **GB 4806.1-2016 + GB 9685-2016 food-contact material migration-limit restrictions**
  • GB 30000 GHS labelling required (Repr. 1B)
  • Customs HS 291732 (esters of orthophthalic acid; DBP)
  • No CBAM equivalent in Chinese domestic regulation
  • NOT subject to active Chinese AD/CVD on DBP; China is the dominant global producer + exporter
  • **China VAT export rebate on DBP has historically varied (verify per HS line + current SAT / MOFCOM circulars before invoicing)**

Importer obligations

Chinese importer of record must hold IECSC listing reliance. **China is the dominant global DBP producer + exporter**; export consignment to US / EU / Australia / Korea triggers multi-overlay compliance documentation (Cal Prop 65 + CPSIA + TSCA Section 6(b) + REACH Annex XIV + Annex XVII + EU Toy Safety Directive + APVMA + KPRC).

Required documents

  • GB-compliant SDS in Chinese (Repr. 1B + Aquatic Chronic 4)
  • China Customs (CCS) declaration HS 291732
  • **GB 24613-2009 toy phthalate BAN compliance where placed in Chinese toy supply chain (must be <0.1% by mass)**
  • **GB 4806.1-2016 + GB 9685-2016 food-contact material compliance where applicable**
  • **Outbound to US / EU / AU / KR: country-specific phthalate-restriction compliance documentation (REACH Annex XIV authorisation reference where applicable + Annex XVII Restriction 51 declaration + Cal Prop 65 reproductive-toxicant warning + CPSIA 2008 BAN compliance + EU Toy Safety Directive compliance)**

Common compliance traps

The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.

  • **China is the dominant global DBP producer + exporter**; major Chinese producers Beijing Yanshan Petrochemical Sinopec + Anhui Yifeng + Hangzhou Hangwei + Jiangsu Pengrun + Shandong Hongxin Chemicals
  • **GB 24613-2009 toy phthalate BAN: DBP at >0.1% by mass in toys + childcare articles**
  • **GB 4806.1-2016 + GB 9685-2016 food-contact material restrictions**
  • GB 30000 GHS classification (Repr. 1B + Aquatic Chronic 4)
  • NOT regulated as dangerous goods at solid / liquid form
  • NOT on China Hazardous Chemicals Catalogue at DBP level
  • **Subject to multiple US + EU regulatory overlays on Chinese-origin DBP exports (Cal Prop 65 + CPSIA + TSCA Section 6(b) + REACH Annex XIV authorisation + Annex XVII Restriction 51 + EU Toy Safety Directive)**
  • **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**
