Phosphoric acid under K-REACH
H3PO4 · 磷酸
Status: Registered. Phosphoric acid 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 phosphoric acid currently (verify against https://www.kita.org/ or Korea Trade Commission filings before invoicing). Korea has limited domestic wet-process phosphoric acid production; structurally net-importer for fertiliser plus industrial plus food-grade sectors. KCFTA preferential zero-duty applies for Chinese-origin imports.
K-REACH treats phosphoric acid as a routine registered substance with no TCCA overlay. Korea limited domestic wet-process phosphoric acid production; structurally net-importer. NO active Korean AD/CVD case. **Phosphoric acid distinguishing pattern across all 5 regimes**: wet-process from sulfuric acid plus phosphate rock (~95 percent of global capacity) plus thermal-process (~5 percent legacy) production route + fertiliser intermediates DAP / MAP / TSP downstream chain (~80 percent of demand globally) plus food-grade phosphates E338 plus industrial cleaning plus metal treatment plus animal feed phosphates + China VAT export rebate plus periodic phosphate export controls + EU and US active AD/CVD on phosphate-derivative products (verify each before relying).
Listing and threshold
| Substance | Phosphoric acid (CAS 7664-38-2), H3PO4 |
|---|---|
| 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

Glossary
K-REACH, K-REACH
South Korean Act on the Registration and Evaluation of Chemicals, the Korean equivalent of EU REACH. Requires registration of substances manufactured in or imported into Korea above 1 tonne per year. Administered by the Ministry of Environment through NIER. Includes phase-in registration tiers, joint submission requirements, and a designated 'Only Representative' mechanism for non-Korean manufacturers.
