What is additional Pricing for Finishes? 

We charge in addition to the original price a percentage markup of 10% for black dye. Therefore a part quoted to be £10 in natural white SLS will be £11.00 in the black dye finish.

Why is this pricing structure used for Black Dye Finish for SLS?

Specialist liquid dye for PA12 Nylon is our highest cost, coupled with equipment investment we are required to charge extra for this finish to cover our costs.
