MMP nickel matte supply to China rises with new East Kalimantan smelter

Mitra Murni Perkasa

MMP nickel matte supply to China will increase after production began on 26 June. Indonesia’s first domestically owned nickel producer started high-grade nickel matte in Kariangau. The RKEF smelter is designed for 28,000 t per year of HGNM. The nickel content exceeds 70 percent, above typical Indonesian grades.

Capacity, technology, and upstream integration

MMP nickel matte supply to China benefits from fully domestic funding and ownership. The project supports Indonesia’s battery supply-chain ambitions and energy transition goals. Chinese EPC firm ENFI built the plant under a 2023 agreement. ENFI is also constructing a 52,000 t per year HGNM project for Posco. Therefore, regional engineering depth should aid reliability and ramp-up.

Market context, pricing, and feedstock choices

China imported about 194,641 t of nickel matte in January–May, up 42 percent year on year. Indonesia supplied roughly 85.6 percent of those volumes. However, offers paused in June amid thin margins, then resumed in early July. Downstream users still view MHP as more cost-effective than HGNM. As a result, smelter premiums will track rival feedstock economics.

MMP nickel matte supply to China could stabilize feed for converters and battery precursors. Meanwhile, higher HGNM grade may improve unit transport and refining economics. Yet pricing must compete with MHP and intermediates tied to sulfate routes. Therefore, offtake terms and sulfuric acid balances will be closely watched.

The Metalnomist Commentary

MMP adds a domestically funded node to Indonesia’s nickel value chain and China’s feed security. The commercial test will be margins versus MHP and contract flexibility. Watch ENFI’s execution, blending strategies, and delivered costs into coastal China.
