Hi-fi brand selling amplifiers, AV receivers and turntables.
Until Marantz traces its cobalt, gold and tin to the mine, it can't show that the miners who dig them are safe or fairly paid.

Why it's graded Lacks transparency
- Not met: Meets 1 of 6 Good requirements.
- Holds the grade back: It relies on high-risk mined materials it can't trace. That alone means a poor grade until it takes steps to trace them.
- It isn't Harm on record, because there's no serious confirmed problem on its record.
- Lacks transparency is still a poor grade: in supply chains like this, workers who can't be seen to be treated fairly are usually underpaid or unprotected.
Good requirements 1 of 6
- Not met: Pays a living wage, or holds a strong fair-pay certificationLiving wage: no evidence
- Not met: Respects worker rightsMost of its products are made in countries such as China and Malaysia, where unions are heavily restricted, and it has no full supply chain audit.
- Not met: Supply chain independently audited or certified, or at least 80% made in countries with strong labour standards
- Met: No confirmed child or forced labour findings or linksAn unconfirmed report of forced labour is listed below. It doesn't affect the grade.
- Not met: Names the factories or farms that make its products, or is fully certified by a scheme that holds and audits that list
- Not met: Traces its cobalt, gold and other conflict minerals to the mine

Evidence
What we found
- Risk across the industry, not a finding about this company: cobalt, tin, tantalum, tungsten and gold mining carry child and forced labour risk (DR Congo, Indonesia), and assembly overtime is widespread.
- Makes part of its range in its own factories
- Relies on metals such as cobalt, gold and tin from artisanal mines where miners, including children, face toxic dust, mercury exposure and deadly tunnel collapses. It hasn't shown any steps to trace these materials to the mine, so it's graded Lacks transparency until it does.
Research notes Marantz names only its Shirakawa Audio Works factory in Japan, home to its high-end models since 2002, and names no other production sites and no suppliers. Sound United's California statement says it does not currently verify, audit or certify suppliers on forced labour. Owner Harman has been an RBA affiliate member since 2022, but its RBA audits cover only its own automotive plants, and there is no living wage commitment.
