How to Use This Calculator

Select mode and enter base rate — what would this shipment cost without hazmat classification?
Verify surcharge rate — check current carrier tariff — hazmat surcharges change. Auto-filled defaults are typical 2024 rates.
Include documentation and training — DOT requires hazmat employee training every 3 years — amortise this across annual shipment volume.

Worked Example

40 LTL hazmat/month, $320 base rate, $85 surcharge, 25 min doc at $28/hr, $3,500 training.

Doc cost/shipment: $11.67
Hazmat premium: $96.67 (30% above base)
Annual premium cost: $46,400 + $3,500 training = $49,900

A 30% hazmat premium must be passed through to customers shipping dangerous goods. If you're not recovering this, you're subsidising hazmat customers from standard freight margin.
