Local blending is not automatically cheaper. It wins under specific conditions, and it is worth being honest about them before committing capital.
Blending wins when
- The product is mostly water or mostly local filler — coatings, mortars, adhesives.
- Duty on finished goods is meaningfully higher than duty on the inputs.
- Lead time matters commercially: three days from your own store versus ten to twelve weeks from a port.
Importing wins when
- The product is concentrated and low volume — speciality additives, some sealants.
- Your volume is genuinely below the smallest viable line and will stay there.
- The formulation needs equipment or raw material handling your site cannot support safely.
Do the arithmetic honestly
- Compare cost per tonne landed in your warehouse, including duty, clearing, inland freight and finance cost.
- Charge the blending case for depreciation, labour, rejects and the working capital tied up in raw material.
- If it is close, import first and build the market. The plant is a better decision once you know the volume.
The short version
Blend when you would otherwise be shipping water, filler or duty. Import when you would be shipping expertise.
