How do I know a scrap yard's weighbridge reading is accurate and not shorting me on weight?
Short answer: Certified trade weighbridges in Australia are required to be regularly calibrated and verified under the National Measurement Institute's trade measurement rules, and should display a current certification. Ask to see the weighbridge's certification sticker or documentation, and if you're selling significant volume regularly, watching the weigh-in and weigh-out process yourself is a reasonable request.

Trade-approved weighing equipment in Australia falls under the National Measurement Institute’s trade measurement framework, which requires regular verification and calibration to ensure readings are accurate for commercial transactions — a legitimate yard’s weighbridge should carry current certification documentation.
What to check
Look for a visible certification sticker or ask the yard directly when their weighbridge was last verified. A legitimate operator will have this readily available and shouldn’t hesitate to show you.
For larger or regular loads
If you’re delivering significant volume on an ongoing basis, it’s reasonable to ask to observe both the empty (tare) weigh-in and the loaded weigh-out, so you can see the actual numbers used to calculate your payment rather than just being told a final figure.
