Glossary term

upstream

EU Conflict Minerals Regulation term for the upstream mineral supply chain from extraction sites through smelters and refiners.

Officially defined term1 formal definition

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.
