Products classified under Tariff item 7501.20
Calcined Nickel Oxide Briquettes
Calcined nickel oxide briquettes are compacted, heat-treated intermediates made from nickel oxide fines, used as charge material in electric arc furnaces for nickel alloy production. The briquetting improves handling and reduces dust losses during smelting, making them a key intermediate product of nickel metallurgy.
7501.20.00Ferronickel Oxide Sinters
Ferronickel oxide sinters are agglomerated intermediates containing nickel and iron oxides, produced from laterite ores for use in ferronickel production. They serve as a key step in pyrometallurgical processing before smelting, and are considered intermediate products of nickel metallurgy.
7501.20.00Nickel Cobalt Oxide Sinters
Nickel cobalt oxide sinters are intermediate sinters containing mixed nickel and cobalt oxides, produced from hydroxide precipitation and thermal treatment. They are used in battery material precursor production, and their sintering creates a stable oxide morphology for further processing, classifying them as intermediate products of nickel metallurgy.
7501.20.00Nickel Laterite Ore Sinters
Nickel laterite ore sinters are sinters produced from nickel laterite ores through rotary kiln agglomeration, containing nickel oxide with magnesium and silica gangue materials. They are used directly in the rotary kiln-electric furnace (RKEF) process for ferronickel production, making them intermediate products of nickel metallurgy.
7501.20.00Nickel Oxide Sinters
Nickel oxide sinters are intermediate products produced by sintering nickel oxide ores or concentrates at high temperatures to form porous agglomerates. They are used in nickel metallurgy as a feedstock for further refining, and are specifically named in the tariff item.
7501.20.00Nickel Spent Catalyst Sinters
Nickel spent catalyst sinters are sintered agglomerates recovered from spent nickel catalysts, containing recoverable nickel oxide for recycling in metallurgy. They are a pre-treatment step before leaching or smelting, and are classified as intermediate products of nickel metallurgy.
7501.20.00Pelletized Nickel Oxide Intermediates
Pelletized nickel oxide intermediates are pelletized forms of nickel oxide produced via green pelletizing and induration, serving as uniform feedstock for submerged arc furnaces in stainless steel production. Pellets offer better gas permeability than sinters, and are considered intermediate products of nickel metallurgy.
7501.20.00Rotary Kiln Nickel Oxide Sinters
Rotary kiln nickel oxide sinters are sinters specifically produced in rotary kiln electric furnace (RKEF) preprocessing, with controlled porosity for optimal smelting reduction. They are essential for Indonesian ferronickel operations and fall under the tariff item as intermediate products of nickel metallurgy.
7501.20.00Synthetic Nickel Oxide Agglomerates
Synthetic nickel oxide agglomerates are synthetic agglomerates made from precipitated nickel hydroxide dried and sintered, providing high-purity oxide for specialty alloy production. Unlike natural ore sinters, these have controlled impurity profiles, and are classified as intermediate products of nickel metallurgy.
