Metal profile: Aluminium →
HS / CNHarmonized System (HS) and Combined Nomenclature (CN)
Goods classifications used in trade: the World Customs Organization's six-digit HS and the EU's eight-digit CN built on it.

The 1913 electrical conductivity standard: 100% IACS is the conductivity of standard annealed copper, 58.0 MS/m at 20 °C.
Metal profile: Copper →
IAIInternational Aluminium Institute
The international association of primary aluminium producers; it publishes statistics on production, energy use and emissions.
Metal profile: Aluminium →

RIRRecycling Input Rate
The share of metal from recycling (post-consumer and pre-consumer scrap) in total metal input to production or use in a given year.
SHFEShanghai Futures Exchange
China's commodity exchange; its non-ferrous metal prices reflect conditions in the largest consuming market.
SLIStarting, Lighting, Ignition batteries
Lead-acid batteries that power the starter, lights and ignition of vehicles – the largest segment of lead use.
Metal profile: Lead →
SX-EWSolvent Extraction – Electrowinning
