Ammonium sulfate under AICIS

(NH4)2SO4 · 硫酸铵

Status: Listed. Ammonium sulfate is on the AICIS (Australian Industrial Chemicals Introduction Scheme; replaced NICNAS on 1 July 2020 under the Industrial Chemicals Act 2019, verify against https://www.industrialchemicals.gov.au/about-us/who-we-are-and-what-we-do) Inventory of Industrial Chemicals as a Listed Industrial Chemical. Australia adopts a light regulatory framework for AS; no SUSMP scheduling. Australian end-use: pasture (sulfur-supplementation), wheat (sulfur-deficient soils in Western Australia, South Australia), canola, cotton (NSW, Queensland), and increasingly sugar cane (Queensland). ChAFTA preferential zero-duty applies for Chinese-origin supply. NO active Australian AD/CVD case on Chinese AS.

AICIS treats AS as a routine listed industrial chemical and the operational compliance work is light (annual AICIS registration, WHS-compliant SDS, ChAFTA Form CO, AQIS biosecurity inspection). The dominant practitioner-facing complexity is grade selection (granular caprolactam-coupled for direct-application vs crystalline coke-oven by-product for NPK blending) and Australian end-use targeting (sulfur-deficient cropping in Western Australia / South Australia wheat belt; NSW / Queensland cotton; Queensland sugar cane). ChAFTA preferential zero-duty makes Chinese-origin AS competitive vs Indonesian (Pupuk Sriwidjaja) and Korean (Capro Corporation caprolactam by-product) alternatives. NO active Australian AD/CVD case on Chinese AS. Beijing has NOT imposed seasonal export-quota on AS (unlike urea / DAP) because by-product-driven Chinese production is structurally over-capacity, making the China-Australia AS lane operationally cleaner than the urea or DAP equivalents.

Listing and threshold

Substance Ammonium sulfate (CAS 7783-20-2), (NH4)2SO4
Regime Australian Industrial Chemicals Introduction Scheme (AICIS), administered by the Department of Health
Jurisdiction Australia
Status Listed
Tonnage threshold AICIS introducer registration required for any business introducing >100 kg/year of any industrial chemical

Classifications under this regime

  • Listed Industrial Chemical on AICIS Inventory
  • Australian GHS classification: typically NOT classified as hazardous (dust irritation only)
  • NO SUSMP scheduling
  • Australian Dangerous Goods Code (ADG 7.7): AS is non-DG (not classified as a dangerous good for transport)
  • NOT classified as carcinogen, mutagen, or reproductive toxicant
  • Department of Agriculture AQIS quarantine requirements apply for biosecurity at import
  • Fertilizer Industry Federation Australia (FIFA) Code of Practice voluntary specifications

Restrictions and conditions of use

  • No AICIS-specific use restrictions for AS
  • No SUSMP scheduling
  • No Australian active AD/CVD case on Chinese-origin AS currently
  • WHS Regulation 2011 hazardous-chemicals handling requirements apply at workplaces handling AS bulk above declared thresholds (dust nuisance)
  • ChAFTA preferential zero-duty applies to Chinese-origin AS (HS 31022100)
  • Department of Agriculture AQIS biosecurity inspection required at import (quarantine for soil-borne pathogens)
  • No federal cadmium / heavy-metal content limit on AS

Importer obligations

The Australian importer of record must be registered with AICIS (online registration is straightforward and annual). For Listed Industrial Chemicals like AS no individual chemical assessment is required. AQIS biosecurity inspection at import requires soil-borne pathogen verification. Australian agricultural buyers (CBH grain growers cooperative, GrainCorp, Elders, AGP, Landmark) are the dominant demand pull for AS in sulfur-deficient cropping (Western Australia, South Australia wheat belt; NSW / Queensland cotton; Queensland sugar cane). Australia has limited domestic AS production (Incitec Pivot has minor capacity); AS is structurally net-imported with China, Indonesia (Pupuk Sriwidjaja), and Korea (Capro Corporation by-product) as main supply origins.

Required documents

  • AICIS introducer registration certificate (annual)
  • WHS-compliant Safety Data Sheet (Safe Work Australia model code format)
  • Customs entry (ICS / ABF) with HS code 31022100
  • ChAFTA Form CO certificate of origin for preferential treatment
  • AQIS biosecurity inspection clearance certificate
  • N minimum 21% (granular) or 20.5% (crystalline) specification certificate
  • Granule-size specification (granular for direct-application; crystalline for NPK blending)

Common compliance traps

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

  • AICIS registration must be CURRENT at customs clearance; lapsed registrations trigger holds
  • AQIS biosecurity inspection is the dominant operational compliance step
  • No Australian active AD/CVD case currently. Australian Anti-Dumping Commission has had periodic investigations on AS imports but no active orders on Chinese-origin AS
  • ChAFTA preferential zero-duty makes Chinese-origin AS competitive vs Indonesian (Pupuk Sriwidjaja) and Korean (Capro Corporation by-product) alternatives
  • Australian end-use: sulfur-deficient cropping is the structural demand pull. Western Australian wheat belt (sulfur-deficient soils), South Australian wheat, NSW / Queensland cotton, Queensland sugar cane. Pasture-supplementation demand (high-altitude / temperate Australian grazing) is secondary
  • Application season: autumn sowing Apr-Jun; demand peak Mar-May. Granular AS preferred for direct-application; crystalline AS (cheaper) requires NPK-blender intermediate processing
  • AS demand is NOT seasonally tightened by Beijing export-quota system (unlike urea / DAP) because by-product-driven Chinese production is structurally over-capacity
  • Caprolactam-coupled granular AS from Chinese suppliers (Sinopec Yueyang, Hengyi Petrochemical, Tianlong) competes with Indonesian and Korean caprolactam by-product on price and grade
