Our Code of Conduct sets the minimum standards expected from every supplier working with Kings of Indigo. It covers
environmental management, chemical use, resource efficiency, material sourcing and animal welfare.

A written standard is only a starting point. Suppliers are expected to identify risks, monitor performance, set measurable improvement targets and address issues over time. Responsibility depends on evidence, continued dialogue and accountability.

Suppliers must maintain systems to identify, monitor and reduce the environmental impacts of their operations.

• Environmental management: maintain a written policy, identify significant impacts and set measurable improvement targets.
• Energy and emissions: track electricity, fuel and gas use, reduce consumption per unit of production and assess lower-emission energy sources where feasible
• Water and wastewater: monitor water use, reduce operational intensity and ensure wastewater is treated and discharged in line with applicable requirements.
• Waste and resource use: prevent unnecessary waste, improve material efficiency and manage recycling responsibly.
• Air, soil and groundwater: monitor relevant emissions, prevent contamination and maintain required permits and documentation.

Suppliers must comply with the Kings of
Indigo Restricted Substances List and all applicable chemical regulations.

The following high-risk processes are prohibited:

• Chlorine bleaching
• Potassium permanganate spraying

Suppliers must keep current safety
documentation, store and handle chemicals correctly, train employees and carry
out regular chemical risk assessments.

We choose fibres according to our materials hierarchy. The highest-performing option is used where the garment can support it without compromising durability or function.

• Post-consumer recycled cotton is our highest-priority cotton route where performance allows.
• Post-consumer recycled cellulose may be used where mechanically recycled fibres can no longer perform.
• Post-industrial recycled cotton reduces production waste and virgin-fibre demand, but is not presented as full circularity.
• Certified organic cotton is our preferred virgin cotton route because it provides clearer restrictions on synthetic pesticides, herbicides, fertilisers and GMOs.
• Regenerative cotton remains a monitored development area and is used selectively where the supply chain provides sufficient transparency.
• Conventional cotton is used only where higher-priority options are technically or commercially unfeasible.
• Material decisions also consider physical durability, chemical-input clarity, land use, fibre composition, recyclability and verified supplier performance.

We do not use virgin animal products with the exception of GOTS-certified organic wool. Our knitwear is made from mulesing-free wool.

We do not accept:

• Mulesing
• Live plucking
• Force-feeding
• Materials derived from endangered or vulnerable species

Social compliance is managed separately
through supplier assessments, recognised standards and continued dialogue.
