Indonesia Artificial Corundum (HS Code 2818) Key Metrics Trend

Market Trend Summary

The Indonesia Artificial Corundum Export trend through the first three quarters of 2025 was marked by extreme volatility, with volumes swinging dramatically between peaks and troughs. Shipments started at 192.8M kg in January, declined in February, then surged 31.96% in April to 263.7M kg before hitting a Q2 peak of 312M kg in June. This expansion reversed sharply in July with a 38.14% collapse to 193M kg, followed by a further 36% contraction in September to 134.6M kg.

Drivers & Industry Context

The July export crash aligns directly with Indonesia's implementation of mineral export restrictions under Law 2/2025, which mandated domestic market prioritization and adjusted royalty structures [ytrade.com]. These policy shifts disrupted supply chains abruptly, explaining the volume volatility despite relatively stable unit prices hovering between $0.37-$0.70/kg. The hs code 2818 value trajectory—declining from $135.9M in January to $63.6M by September—reflects both volume erosion and price pressure from these trade policy interventions, compounded by concentration risks in key markets like India and China (ytrade.com).

Indonesia HS Code 2818 Export Breakdown

Market Composition & Top Categories

Indonesia's HS Code 2818 export market is overwhelmingly dominated by aluminium oxide other than artificial corundum, which accounts for over 96% of the total export value and 94% of the weight shipped. According to yTrade data, this sub-category was the primary driver of Indonesia HS Code 2818 Export activity throughout the first three quarters of 2025. The remaining exports consist of aluminium hydroxide and a minimal volume of artificial corundum, which together represent less than 4% of the value.

Value Chain & Strategic Insights

The unit price disparity highlights a clear value chain differentiation, with artificial corundum priced at 3.35 USD per kilogram compared to around 0.3-0.5 USD/kg for other forms. This HS Code 2818 breakdown reveals a specialized market where higher-grade products command premium prices, indicating quality sensitivity rather than commodity-style price competition. The trade structure suggests that Indonesia's exports are primarily bulk commodities, with limited high-value specialization in this segment.

Indonesia Artificial Corundum Destination Countries

Geographic Concentration & Market Risk

India dominates Indonesia's Artificial Corundum export destinations from January to September 2025, accounting for 22.46% of total value. This high market share creates a notable dependency risk, as any economic shift in India could directly impact Indonesian export revenues. Australia and Malaysia follow as secondary markets, but their combined value does not match India's singular influence.

Purchasing Behavior & Demand Segmentation

India's value ratio (22.46%) exceeds its weight ratio (19.66%), signaling quality-conscious demand for high-value specifications among trade partners for Artificial Corundum. This premium intent is consistent across other major buyers like Australia and Malaysia, where value also outpaces weight. While Japan and South Korea show high shipment frequency, their lower value ratios indicate smaller, perhaps more specialized orders. The market clearly offers margin potential over pure volume scale.

Action Plan for Artificial Corundum Market Operation and Expansion

• Diversify buyers immediately: The 95.88% buyer concentration is unsustainable. Target secondary markets like Japan and South Korea, where frequent but smaller orders indicate niche demand.
• Lock in long-term contracts: With policy shifts (Law 2/2025) disrupting supply, secure commitments from key accounts like ALCOA to stabilize revenue.
• Shift to premium products: Capitalize on the 10x price gap for artificial corundum ($3.35/kg) by reallocating capacity from bulk aluminium oxide exports.
• Monitor India’s economic indicators: With 22.46% of value tied to India, track GDP, tariffs, and domestic production to preempt demand shocks.
• Optimize logistics for bulk shipments: Aluminium oxide’s low value-to-weight ratio demands cost-efficient transport to preserve margins.
