Cable Trays & Earthing from India to Australia: AS/NZS Standards, ECTA Duty & Mining Procurement

Australia imported approximately USD 22 million of cable trays, gratings and earthing systems from India in the 12 months to March 2026. Two procurement sectors dominate: the mining and resources industry in Western Australia and Queensland (primarily BHP, Rio Tinto, Fortescue Metals Group and their tier-1 EPCM contractors), and the solar and grid infrastructure build-out across all states under the Australian Energy Market Operator (AEMO) Integrated System Plan. The Australia–India Economic Cooperation and Trade Agreement (ECTA), in force since May 2023, eliminated import duty on cable trays and most metal structural products from India. Combined with India's competitive manufacturing cost base, this has made Indian-sourced cable management increasingly attractive for Australian projects versus locally-held stock or European supply.

Import duty under Australia–India ECTA

Under the Australia–India Economic Cooperation and Trade Agreement (ECTA), which entered into force on 29 December 2022 (provisional) and reached full implementation from May 2023, the import duty on cable trays (HS 7308.90), structural steel sections (HS 7308.20, 7308.40), electroforged gratings (HS 7308.90) and earthing electrode products (HS 7326.90) from India to Australia is 0%. This is a reduction from the MFN duty rate of 0–5% that applied before ECTA. To claim the ECTA preferential rate, the Indian exporter must issue an ECTA Certificate of Origin, which confirms the goods meet the Rules of Origin requirements under the agreement. The ECTA COO is issued by EEPC India or a designated issuing authority — it must be requested specifically on the purchase order and is separate from a standard non-preferential COO. For most steel and metal product categories, the Rules of Origin criterion is that the product is manufactured or substantially transformed in India (change in HS heading from the imported raw material to the exported product).

Australian standards for cable management — what applies

Australia does not have its own standalone cable tray standard equivalent to IEC 61537. Cable management systems in Australia are governed by AS/NZS 3000:2018 'Wiring Rules' (the primary electrical installation standard), which references cable management system requirements in Section 3.5. AS/NZS 3000 requires that cable management systems be suitable for the intended purpose, rated for the load and environment, and installed to prevent mechanical damage to cables. For specific cable tray product selection: IEC 61537 is widely accepted in Australia as the applicable product standard. Many large project specifications for mining and infrastructure explicitly reference IEC 61537 load classes (A, B, C, D per Part 1 classification) and HDG coating to ASTM A123. For galvanizing: AS/NZS 4680 (same technical content as ISO 1461) is the Australian galvanizing standard — ASTM A123 and AS/NZS 4680 are broadly equivalent for thickness requirements and are both accepted on Australian projects.

Mining sector procurement: BHP, Rio Tinto, FMG specifications

Tier-1 Australian mining companies operate through EPCM contractors (Worley, GHD, Hatch, Wood, Jacobs) who manage materials procurement for iron ore, lithium, copper and gold projects. The EPCM contractor issues a project-specific Technical Specification for cable management, which typically references IEC 61537, AS/NZS 4680 for galvanizing, and project-specific wind load and seismic requirements based on AS/NZS 1170 (Structural Design Actions). For Western Australian Pilbara and Goldfields projects — where ambient temperatures regularly exceed 45°C and UV exposure is extreme — the project specification may require higher-than-standard HDG coating thicknesses (100 µm minimum vs 85 µm standard) or specific alloy specifications. Third-party inspection at origin by a nominated agency (Bureau Veritas, Intertek, CCIC) is required on most mining capital projects above AUD 50 million. Vajra's Howrah plant accommodates TPI witness visits; we produce dimensional reports, coating certificates and MTC in the format required by Australian EPCM quality plans.

Solar and grid infrastructure procurement

Australia's renewable energy build-out under the AEMO ISP targets 43% renewable generation by 2030 (Capacity Investment Scheme) and 82% by 2030 under the federal government's target. This is driving large-scale demand for solar mounting structures, cable management for utility solar farms, and earthing systems for grid-connected solar and wind farms. For solar applications in Australia: cable trays for solar farms are typically specified to IEC 61537 plus project wind loads per AS/NZS 1170.2, with HDG to AS/NZS 4680 minimum 85 µm. Solar mounting structures must be designed to AS/NZS 1170.2 wind loads for the specific site (tropical cyclone-rated for North Queensland and WA); AS/NZS 1170.1 dead and live loads. Australian solar developers (AGL, Origin Energy, Amp Energy, Lightsource bp) and their EPC contractors typically source mounting structures and cable management either through a local distributor or direct from approved Indian manufacturers with AS/NZS-compliant design certification.

Documentation for an Australia-bound shipment

• ECTA Certificate of Origin: issued by EEPC India — must be requested on the purchase order to access 0% duty. Without ECTA COO, the MFN duty rate applies (0–5% depending on HS subheading).
• Commercial Invoice: AUD or USD value, accurate 8-digit Australian HS code, country of origin (India), Incoterm (CFR Port Botany / Fremantle / Brisbane), net and gross weight.
• EN 10204 Type 3.1 MTC: required by all mining EPCM specifications and most solar EPC contracts. Must show steel grade (AS/NZS 3678 or equivalent), chemical analysis, tensile and yield strength, and elongation.
• HDG Coating Inspection Report: XRF or magnetic gauge measurements per AS/NZS 4680 (equivalent: ASTM A123). Minimum 5 readings per m². Average ≥85 µm; minimum single reading ≥70 µm.
• Packing List: carton/bundle level with weights — Australian customs uses this for quarantine inspection and container weight verification under the Chain of Responsibility legislation.
• Biosecurity Declaration: Australia has strict biosecurity requirements. Timber packaging (pallets, dunnage) must be ISPM 15 heat-treated and marked. All steel products must be free of soil, grease and organic material on the surface. Non-compliance results in container quarantine and treatment costs.

Port of entry by project location

Fremantle (WA): the primary port for Pilbara mining projects and Perth-area construction. Inland transport via road or rail to Geraldton, Karratha, Port Hedland. Port Botany (NSW): for Sydney, Canberra and most NSW projects. Brisbane (QLD): for Queensland coal, copper and gold project sites and coastal Queensland solar farms. Melbourne (VIC): for Victorian and South Australian projects. Adelaide (SA): direct port for SA projects — smaller throughput but direct to the Olympic Dam and Gawler Craton mining districts. Transit times from Kolkata: Kolkata to Fremantle direct: 18–22 days. Kolkata to Port Botany or Brisbane: 22–28 days, typically via Singapore transshipment. Kolkata to Melbourne: 22–26 days.

Request the ECTA Certificate of Origin on your purchase order — it saves 5% import duty and the cost of issuing it is a few hundred rupees. Many Indian exporters forget to offer it because ECTA is still relatively new. Make it a standard clause in your PO terms.
