JECAMECManage supplier listing

Monthly national copper shipment tonnage decomposed by end-use demand sector, published as a dated PDF: seven sectors (telecommunications, electric power, electrical machinery, automotive, construction and electrical wholesale, other domestic demand, exports) plus a total, reported as a full monthly grid for the trailing ~35 months and as fiscal-year averages back to FY2004, with month-on-month and year-on-year ratio columns. Every monthly observation is a tonnage of copper consumed by a named end industry — an implied copper-intensity read on each downstream sector rather than a physical supply series. Companion files in the same dated directory carry an economic-condition series.

Type
not stated
Format
Tabular time series published as monthly PDFs (fixed grid: sector columns × month rows, plus chart) with derived ratio columns; no API, no CSV or Excel endpoint
Volume
Small and dense: 8 series × 12 months = 96 observations per year on the monthly cut with ~35 months printed per release, plus 8 series × 21 fiscal years (FY2004 to FY2024) in the annual block — roughly 170 published figures per monthly release over a continuous ~21-year × 7-sector monthly panel. Companion economic-condition files in the same directory add columns.
Users
N/A as a subscriber metric — the catalog is a free public lookup service funded by member and vendor participation rather than a metered product. The relevant population is the association's institutional contractor membership plus the vendor community registering catalog data; treat reach as institutional, not registered accounts.
History
21 years
Update frequency
not stated
Growth
Active — monthly cadence maintained, with dated releases current into 2026 in the same file tree; the catalog platform was recently re-platformed and URL-migrated, indicating investment. A mature institution rather than a growth story.
Launched
Underlying association established 1954 (reorganized as a general incorporated association in 2011); the statistical compilation predates the web release — the annual block in the source document already starts at FY2004, so the copper series circulated in print form well before the catalog site launched.
