What does upstream mean?

Upstream is a chain-position term for conflict-minerals due diligence. It marks the extraction-to-smelting/refining segment where source, custody, area-risk, and smelter/refiner evidence must be kept together rather than treated as a generic supplier tier.

Practical application

Implementation records should capture the upstream segment, extraction sites, smelters and refiners, custody-chain evidence, mineral scope, country or area-risk context, economic operators in sequence, and links to due-diligence risk records.

Minespider commentary

Conflict-minerals upstream is a sourcing-boundary control: weak upstream evidence can break the connection between extraction context, custody sequence, smelter/refiner identity, and downstream material claims.

Common confusions

Upstream is not every supplier before the final customer; in this source it runs from extraction sites to smelters and refiners inclusive.
Upstream evidence is not proven by a country name alone; custody, source, and actor sequence still matter.
Upstream is not the same as downstream product-manufacturing or final-product incorporation.
