Pricing
Individual Test
UN-4 self-heating and auto-ignition classification projects fall between $650 and $2,600 USD per sample, depending on test matrix ( single test screening vs. full UN-4.2 program). Multi-variant studies (e.g., different moisture contents, particle sizes, or processing conditions) are typically quoted as a per-test-point fee however we do offer discounts for bulk testing and special studies. Any special reparation of samples (milling, grinding, etc.) is at standard lab rate. Rush service available for an additional fee.
