What duty and tariff issues apply to plastic injection moulding and tooling?
Confidence 4/5 Established practice
Duty considerations for plastic injection moulding and tooling:
Moulds and finished parts are classified separately and can attract different rates, so the tool and the production run should be invoiced as distinct line items rather than bundled.

What goes wrong with plastic injection moulding and tooling
- Cutting a mould for a product with unproven demand. Validate the market with machined or printed units first.
- Not naming the steel grade. A 718H or a P20 mould behaves very differently to a soft prototype tool at 100,000 shots.
- Skipping the DFM review. A part designed without draft angles, uniform wall thickness or adequate radii will mould badly or not at all.
- Assuming one cavity. Multi-cavity tools multiply output and cost together, and the right answer depends on annual volume, not on the first order.
- Forgetting that the tool has a finite shot life and needs maintenance.
