Why do buyers dock price for plastic, rubber, or wood still attached to metal items?
Short answer: Non-metal attachments add weight and volume without adding any scrap metal value, and they also require the buyer to remove them before processing — buyers typically deduct either an estimated weight allowance or a flat contamination discount to account for this, so removing attachments yourself before selling almost always results in a better net price for the same underlying metal.

Scrap is typically priced by weight — plastic housings, rubber seals, or wood components add weight that isn’t actually metal, meaning a buyer paying per kilo for the whole item is effectively overpaying if they don’t account for this.
Why removal labour also factors in
Beyond the weight issue, someone has to physically remove these components before the metal can be processed — if that’s the buyer’s labour rather than yours, it’s reflected in a lower price offered.
What’s actually worth removing
Larger or heavier attachments (thick plastic housings, substantial rubber components) are usually worth the effort to remove yourself — small clips or minor fasteners typically aren’t significant enough to bother with.
