Understanding the terms associated with weight measurement is crucial to ensuring fair compensation for your scrap materials. One term that plays a pivotal role in this process is “Tare Weight.” Let’s delve into what Tare Weight means, how it differs from Gross and Net weights, and why scrap yards employ this measurement.

Scrapping Starts with Gross Weight
When you arrive at a scrap yard with a load of materials, the initial weight recorded is known as the Gross Weight. This figure encompasses the total weight of everything you bring in, from individual items to truckloads.
For example, you put four buckets of #1 tubing on the scale on the right, and the weight reads “75 lbs.” You now have a Gross weight of 75 lbs.
Tare Weight: Deducting any Non-Metals
Tare Weight, often labeled as a “weight deduction,” represents the weight of non-metallic or non-scrap items. When you empty your (hopefully organized) containers of tubing or dump Light Iron out of your truck, the weight recorded on the scale minus the weight of the container or truck is your Tare Weight.
Net Weight: The Bottom Line
The Net Weight is the crucial figure that determines your payment. It is calculated by subtracting the Tare Weight from the Gross Weight. This is the amount of metal or material you will be compensated for. For instance, if that bucket of tubing has a Gross Weight of 75 lbs and a Tare Weight of 6 lbs, your Net Weight is 69 lbs, and you will be paid for that amount of brass.
Remember! The Weight Formula is always: Gross Weight – Tare Weight = Net Weight.
Why Scrap Yards Use Tare Weight
Scrap yards use Tare Weight as a standard practice to ensure accurate measurements and fair compensation. By subtracting the weight of non-metallic items, they can precisely determine the amount of scrap material the customer brings.
Every Yard Implements Tare Weight Differently
Scrap yards may implement Tare Weight at their scales in various ways. Some use preset weight deductions, while others rely on pre-measured boxes or containers. Customers need to be aware of their yard’s specific practices and, if required, double-check the Tare Weight on their containers to avoid discrepancies.
Tips for Accuracy at the Scrap Yard
Ensuring accurate measurements at the scrap yard is crucial for fair compensation. Here are some tips:
- Watch The Weights: Verify the scale readings during unloading to catch any discrepancies.
- Ask About Scale Accuracy: Inquire if the scrap yard regularly tests and calibrates their scales for accuracy.
- Double Check Tare Weights: Confirm the Tare Weights provided by the scrap yard, especially if they estimate them.
- Check The Math: Ensure that the math is correct when calculating Net Weight, especially if the receipts are hand-written.
- Examine Deductions: Look out for additional deductions on your receipt, such as fees for mixed or dirty metals.
- Verify Material Grades: Confirm that the metals are classified correctly on your receipt to ensure accurate pricing.
- When In Doubt, Ask: If there’s any confusion or discrepancy, seek clarification from the scale manager or supervisor before leaving the yard.
By understanding Tare Weight and being vigilant about measurements, scrappers can ensure a fair and transparent transaction at the scrap yard. Clear communication is critical to maximizing your profits and keeping you and the scrap yard happy!
