Ship Hazardous Materials with Confidence

Automatic 49 CFR and IATA DGR compliance. Just add a UN number to your items - we handle the rest.

Hazmat Shipping is Complex and Risky

Segregation Rules

Incompatible materials like oxidizers and flammables cannot be packed together - a violation can cause fires or explosions.

Complex Regulations

49 CFR for ground, IATA DGR for air - different rules, quantity limits, and packaging requirements for each mode.

Costly Fines

Non-compliance can result in fines up to $250,000 per violation, shipment delays, and reputational damage.

Manual Classification

Looking up UN numbers, hazard classes, and packing groups for every item slows down fulfillment operations.

Ultra-Simplified Hazmat API

Just add hazmat_un to your items. That's it.

Our built-in UN reference database automatically populates the hazard class, packing group, proper shipping name, and all regulatory constraints. No need to memorize regulations or maintain your own hazmat database.

  • Auto-Classification: UN number lookup handles everything
  • Smart Segregation: Incompatible materials automatically separated
  • Mode-Specific Rules: Ground, air, and sea shipping constraints applied
  • Packing Group Enforcement: PG I/II/III severity levels respected

Automatic Compliance Features

Segregation Matrix

Oxidizers kept separate from flammables. Explosives isolated. Corrosives away from water-reactive materials. All automatic.

Orientation Control

Liquids (Class 3, 8) automatically flagged for upright orientation to prevent leaks during transport.

Fill Ratio Limits

Explosives limited to 70% fill, oxidizers to 75%. Ensures safe packaging with proper cushioning space.

Shipping Mode Rules

IATA quantity limits for air, 49 CFR for ground, IMDG for sea. Constraints applied based on your shipping mode.

Comprehensive Hazard Class Coverage

Class 2: Gases Class 3: Flammable Liquids Class 4: Flammable Solids Class 5: Oxidizers Class 6: Toxic Class 8: Corrosives Class 9: Miscellaneous

Built-in UN Reference Database

Our database covers 24+ common hazmat items including:

  • UN1950 - Aerosols, flammable
  • UN1203 - Gasoline
  • UN1263 - Paint
  • UN1789 - Hydrochloric acid
  • UN1830 - Sulfuric acid
  • UN2031 - Nitric acid
  • UN3481 - Lithium ion batteries
  • UN3480 - Lithium ion batteries (standalone)
  • UN1075 - LPG
  • UN1072 - Oxygen, compressed
  • UN2794 - Lead-acid batteries
  • UN1942 - Ammonium nitrate

Real-World Scenarios

E-Commerce: Lithium Batteries

Shipping electronics with lithium batteries? Just add hazmat_un: "UN3481" to battery-containing items.

System automatically applies IATA Section II limits for air shipping and ensures batteries are properly documented.

Industrial: Paint & Solvents

Mixed order with paint (UN1263) and oxidizer-based cleaners? Our segregation matrix keeps them in separate packages.

Flammables and oxidizers are automatically placed in different segregation groups to prevent dangerous reactions.

Chemical Supply: Acids

Shipping hydrochloric acid (UN1789) with sulfuric acid (UN1830)? Both are Class 8 corrosives - compatible for same package.

Same-class materials are intelligently grouped together, reducing package count while maintaining compliance.
