RFQ Essentials & Common Questions
Why is unit specification critical in RFQs?
Ambiguous units (e.g., “Ton”) cause up to 10% variance in material quantity. Always specify Metric Ton (1,000kg), Short Ton (907kg), or Long Ton (1,016kg) in your Request for Quotation.
How do I convert steel/metal prices from per lb to per kg?
To convert price/lb to price/kg, multiply by 2.2046. To convert price/kg to price/lb, divide by 2.2046. This is crucial for comparing domestic (US) and international quotes.
What is the difference between Net Weight and Gross Weight?
Net Weight (NW) is the weight of the product alone. Gross Weight (GW) includes packaging (pallets, crates). Shipping costs are often calculated on Gross Weight, while raw material costs are based on Net Weight.
Troy Ounce vs. Ounce for Precious Metals
Gold and silver are measured in Troy Ounces (31.1g), not standard Avoirdupois Ounces (28.35g). Use the “Ounce (oz)” unit here for standard materials, and ensure your supplier specifies if using Troy units.
Shipping Container Load Limits (Weight vs. Volume)
A standard 20ft container typically has a max payload of approx. 28 Metric Tons (28,000 kg). Ensure your total Gross Weight does not exceed road legal limits at the destination port.
