Is there a legal requirement for scrap yards to have their scales certified, and can I ask to see proof?
Short answer: In most jurisdictions, commercial scales used for trade purposes, including scrap yards, are subject to trade measurement regulations requiring periodic certification and inspection — you can absolutely ask to see current certification, and a legitimate buyer should have no issue showing it, since this is standard regulatory compliance rather than a special request.

Scales used for commercial transactions, where the weight directly determines payment, are typically regulated under trade measurement laws specifically because accuracy in this context has a direct financial impact on both parties — this isn’t unique to scrap yards, but applies broadly to any commercial weighing used for trade.
What certification typically involves
Certified commercial scales are generally required to be periodically tested and calibrated by an accredited authority, with certification displayed or available on request, confirming the scale meets accuracy standards as of the certification date.
What to do if a buyer can’t or won’t show certification
A legitimate buyer operating a certified scale should have no hesitation providing this documentation when asked — reluctance or an inability to produce current certification is a reasonable basis for caution, and worth checking your specific jurisdiction’s trade measurement authority if you want to verify a buyer’s compliance independently.
How ScrapTrade Makes This Easier
Asking ScrapTrade buyers directly about their scale certification status before committing to a large sale is a reasonable, low-effort verification step worth taking.
