Ammonium nitrate (AN) under K-REACH

NH4NO3 · 硝酸铵

Status: Registered. Ammonium nitrate is registered under K-REACH and listed as a Priority Existing Chemical (PEC). NOT on Korea TCCA Toxic Chemicals list. **Korean civil explosives regulation** applies to explosives-grade AN (verify the current statute name and permit chain against the Korean Ministry of Trade, Industry and Energy or the National Police Agency portal before relying on "Civil Explosives Act" specifically): explosives-grade requires a civil-explosives permit + secure transport + secure storage. NO active Korean AD/CVD case (verify against the Korea Trade Commission portal before invoicing). Korea has limited domestic AN production; structurally net-importer for fertiliser + ANFO mining-explosives industries. KCFTA preferential zero-duty applies for Chinese-origin imports.

K-REACH treats AN as a routine PEC-registered substance with no TCCA overlay but **Korean civil explosives regulation** for explosives-grade is the dominant practitioner overhead (verify the current statute name against the Korean Ministry of Trade, Industry and Energy or National Police Agency portal before relying on "Civil Explosives Act" specifically). Korea has limited domestic production. KCFTA preferential zero-duty applies. **Ammonium nitrate distinguishing pattern across all 5 regimes**: closes nitric acid batch 40 + ammonia batch 37 chains directly + dual-use civil + military explosives precursor + EU Explosives Precursors Reg 2019/1148 + Annex XVII Restriction 58 + EU CBAM Phase 1 from January 2026 + ATF + DHS CFATS chemical-of-interest (verify the current framework names against the ATF and DHS CISA portals before relying on SAFE Explosives Act 2002, Public Law 110-161, or CFATS Tier 1 specifically) + Australian HSEMP plus NCSP Type 5 SSAN + Korean civil explosives regulation + Beijing 0% VAT rebate (food-security signal; verify current rebate rate at the State Taxation Administration before invoicing) + seasonal export-quota Feb-May + China Civil Explosives Materials Catalog + 4 fertiliser-grade variants (CAN + AN-fuel grade + porous prilled + ANFO) + disaster legacy (Beirut 2020 + Texas City 1947 + Oklahoma City 1995 + Toulouse 2001; verify each event against CSB.gov or national investigation reports before quoting individual fatality counts).
