> Komatsu's material lane is OEM-spec remanufacturing of engines, transmissions, hydraulics and drivetrains, not a vague equipment-circularity claim.

## Material inputs to resolve

Construction and mining equipment with remanufactured parts

Komatsu describes components rebuilt and tested to original equipment specifications. That proves a product architecture for component return, not a specific core stream or regional capacity.

**OEM spec** Remanufacturing standard

**Open** Plant, grade and buyer evidence

**Screening** No commercial claim

**As of** September 18, 2026

- Returned engines and transmissions
- Hydraulic and drivetrain components

### Outputs and residuals to resolve

- Remanufactured OEM-spec components
- Nonrecoverable material fractions

**First decision:** Return rate, condition codes and turnaround.

## What is disclosed

Komatsu states that remanufacturing reuses and salvages components through original equipment specifications, assembly processes and testing.

#### What remains unproven

No public source establishes a component family's regional core availability, price or rebuild slot.

### Decision boundary

The public record supports one bounded next move: Return rate, condition codes and turnaround. It does not establish a buyer, commercial approval or supply agreement.

## Material flow map

| Material or stream | Qualification gate | Process or destination | Evidence still needed |
|-|-|-|-|
| Returned engines and transmissions | Composition and specification | Remanufactured OEM-spec components | Site, volume and buyer evidence |
| Hydraulic and drivetrain components | Condition and logistics | Nonrecoverable material fractions | Yield and destination evidence |

This is a public screening map. It separates company-disclosed flows from open qualification work. It does not convert a destination into a buyer or an announced ambition into operating capacity.

## Three defensible entry lanes

#### Core-return reliability

Choose one component family and service region before treating reman as a material lane.

**Next evidence:** Return rate, condition codes and turnaround.

#### Qualification path

Separate disclosed company activity from a usable commercial lane.

**Next evidence:** Named site, product grade and technical owner.

#### Commercial boundary

Do not infer customer demand from corporate reporting.

**Next evidence:** Buyer specification, commercial terms and approval.

Source hierarchy: filings and company disclosures first. The brief states what those sources support and leaves the unresolved plant, grade, permit, buyer and mass-balance questions explicit.

## Material Transition editorial interpretation

The next useful working session starts with: Return rate, condition codes and turnaround.
