What is the tonnage threshold for K-REACH on carbon black?

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)

CAS 1333-86-4 · K-REACH · Republic of Korea

Carbon black under K-REACH

C (amorphous) · 炭黑

Status: Registered. Carbon black is registered under K-REACH. NOT on Korea TCCA Toxic Chemicals list (verify against the current TCCA Toxic Chemicals list at https://www.nics.go.kr/ before relying). NOT on Korean Drug Management Act precursor list. NO active Korean AD/CVD case on Chinese-origin carbon black currently (verify against https://www.kita.org/ or Korea Trade Commission filings before invoicing). Korea has substantial domestic carbon-black production capacity (OCI Materials, Korea Carbon Black, Continental Carbon Korea); balanced producer-importer for Korean tire / rubber sectors (Hankook + Kumho + Nexen tire manufacturers are major Korean carbon-black consumers). KCFTA preferential zero-duty applies for Chinese-origin imports. IARC Group 2B since Volume 93 (2010).

K-REACH treats carbon black as a routine registered substance with no TCCA overlay. Korea has substantial domestic production capacity; balanced producer-importer for Korean tire / rubber sectors (Hankook + Kumho + Nexen). NO active Korean AD/CVD case. **Carbon black distinguishing pattern across all 5 regimes**: Production via oil furnace process ~95% of global capacity (heavy aromatic feedstock partial combustion); smaller volumes from thermal black + channel black + acetylene black + lamp black + tire and rubber industry primary end-use ~70% (tread + sidewall + carcass + inner-liner reinforcement) plus non-tire rubber goods ~20% (conveyor belts + hoses + seals) plus pigment / plastics / printing inks / paints ~10% plus speciality electronics (toner + battery) downstream chains + low hazard profile across regimes (respirable dust handling) but **IARC Group 2B since Volume 93 (2010) + US Cal Prop 65 carcinogen 21 February 2003 (airborne unbound respirable particles) + US Cal/OSHA PEL 3.5 mg/m3 plus NIOSH REL 3.5 mg/m3 (no federal OSHA Table Z-1 entry) + NIOSH carbon-black-with-PAHs cap 0.1 mg/m3 cyclohexane-extractable + freshly-produced UN 1361 Class 4.2 spontaneously combustible until conditioned + multiple historical US AD reviews on Chinese tires flow duty exposure downstream from carbon-black chain + China dominates global capacity with Black Cat Carbon Black ranking among world's top producers**.

Listing and threshold

Substance	Carbon black (CAS 1333-86-4), C (amorphous)
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: typically NOT classified as hazardous beyond particulate dust
NOT on Korea TCCA Toxic Chemicals list
NOT on Korean Drug Management Act precursor list
Korean Customs Service (KCS) HS code: 280300
**IARC Group 2B (possibly carcinogenic to humans) since Volume 93 (2010)** (verify against monographs.iarc.who.int Volume 93)

Restrictions and conditions of use

No TCCA Toxic Chemicals Handling Permit required
KOSHA MSDS in Korean required at workplace (with respirable particulate dust handling)
NO active Korean AD/CVD case on Chinese carbon black currently
KCFTA preferential zero-duty applies (HS 280300)

Importer obligations

Korean importer of record must hold K-REACH registration. Korea has substantial domestic carbon-black production capacity (OCI Materials + Korea Carbon Black + Continental Carbon Korea); balanced producer-importer for Korean tire / rubber sectors (Hankook + Kumho + Nexen tire manufacturers are major Korean carbon-black consumers).

Required documents

K-REACH registration number on Korean side
Korean MSDS (with respirable particulate dust handling notes)
KCS declaration with HS 280300
China-Korea FTA Form CO
