Titanium dioxide under K-REACH

TiO2 · 二氧化钛

Status: Registered. Titanium dioxide is registered under K-REACH and listed as a Priority Existing Chemical (PEC). TiO2 is NOT TCCA-restricted, NOT on the Korean Drug Management Act precursor list. Korea has NOT adopted the contested EU Carc Cat 2 classification or the EU E171 food-additive ban; MFDS continues to permit food-grade TiO2 with concentration limits per the Korean Food Code.

K-REACH treats TiO2 as a routine PEC-registered substance with no TCCA overlay. Korea did NOT adopt the contested EU Carc Cat 2 reclassification or the EU 2022 E171 food-additive ban; MFDS continues to permit food-grade TiO2 under the Korean Food Code with concentration limits. Korean cosmetic and sunscreen industry demand (Amorepacific, LG Household & Health Care, Cosrx, CJ CheilJedang K-beauty exports) is the structural premium-margin pull; KCFTA preferential zero-duty supports cost-competitive Chinese supply. Sunscreen-grade nano-TiO2 commands MFDS Cosmetic Act compliance; the China-Korea TiO2 lane runs heavy on cosmetic-and-personal-care demand.

Listing and threshold

Substance Titanium dioxide (CAS 13463-67-7), TiO2
Regime Korea Act on the Registration and Evaluation of Chemicals (Act No. 11789, "K-REACH" amended 2018)
Jurisdiction Republic of Korea
Status Registered
Tonnage threshold K-REACH registration required for existing chemicals manufactured or imported >1 tonne/year (verified per Korean Ministry of Environment / NIER guidance, https://chemical.chemlinked.com/chempedia/k-reach; threshold for new substances was reduced from 0.1 t/y to 1 t/y effective 1 January 2025 per K-REACH 2025 amendment)

Classifications under this regime

  • Korean GHS classification: NOT classified as Carc under Korean harmonised list (Korea did not adopt the EU 2020 reclassification)
  • Korea Occupational Safety and Health Act (KOSHA) workplace exposure standard: 10 mg/m³ inhalable, 3 mg/m³ respirable
  • IARC Group 2B classification stands independently of K-REACH
  • NOT on Korea TCCA Toxic Chemicals list
  • NOT on Korea Drug Management Act precursor list
  • Korean Customs Service (KCS) HS code: 32061100
  • Listed in K-REACH database under "general industrial use, low-hazard"
  • MFDS Korean Food Code permits TiO2 as food additive with concentration limits
  • MFDS Cosmetic Act permits TiO2 as cosmetic colorant / sunscreen UV filter with concentration limits

Restrictions and conditions of use

  • No TCCA Toxic Chemicals Handling Permit required
  • No Chemical Accident Prevention Plan (CAPP) required
  • Korea Industrial Safety and Health Act (KOSHA) MSDS in Korean required at workplace
  • Korea Customs Service requires K-REACH registration number on import declaration
  • MFDS Korean Food Code purity criteria apply for food-grade product (continues to permit, unlike EU E171 ban)
  • MFDS Cosmetic Act sun-protection-factor requirements apply for sunscreen-grade nano-TiO2

Importer obligations

The Korean importer of record must hold K-REACH registration in their own name or rely on an Only Representative (OR). Food-grade TiO2 continues to be permitted under the Korean Food Code (MFDS) with concentration limits, unlike the EU 2022 ban; this is a jurisdictional divergence. Sunscreen-grade nano-TiO2 is permitted under MFDS Cosmetic Act with sun-protection-factor requirements; Korean cosmetic and sunscreen industry demand (Amorepacific, LG Household & Health Care, Cosrx) is structural. KCFTA preferential zero-duty supports cost-competitive supply.

Required documents

  • K-REACH registration number on Korean side (registrant or OR-appointed)
  • Korean-language MSDS compliant with Korean GHS
  • Korean Customs Service (KCS) declaration with HS code 32061100
  • China-Korea FTA Form CO certificate of origin for preferential treatment
  • MFDS food-grade compliance certificate (where food-grade)
  • MFDS Cosmetic Act compliance documentation (where cosmetic / sunscreen grade)

Common compliance traps

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

  • Korean GHS hazard-statement codes use H-codes mapped to Korean translations; SDS in English-only is rejected at workplace inspection
  • Korea did NOT adopt the EU 2020 Carc Cat 2 reclassification; Korean SDS should reflect Korean classification, not EU legacy
  • Korea continues to permit food-grade TiO2 under MFDS; do not assume EU 2022 E171 ban applies. Confirm destination buyer accepts food-grade per Korean Food Code
  • Sunscreen-grade nano-TiO2 (Korea cosmetic and personal-care market) requires MFDS Cosmetic Act compliance; Korean SPF claims are MFDS-regulated
  • KCFTA preferential zero-duty applies but verify producer-specific eligibility (Form CO certified by Chinese authority)
  • Korean cosmetic and personal-care industry (Amorepacific, LG H&H, Cosrx, CJ CheilJedang) is high-growth premium-margin demand for spec-grade nano-TiO2
