When you’re shipping and storing building materials across multiple states or provinces, labeling rules can become a confusing patchwork. From treated lumber to flammable products, each jurisdiction has its own requirements—and staying compliant isn’t just about fines. It also helps ensure safety, transparency, and customer trust.
Here’s how to keep your material labeling and handling practices aligned with state-specific rules.
- Treated Wood Labeling
Many states require:
The type of chemical treatment (e.g., ACQ, CA-B, CCA)
Intended use (above-ground, ground contact, marine use)
Handling and disposal warnings
EPA or provincial compliance markings
Tip: Never remove manufacturer tags, and keep SDS sheets accessible at all times.
- Flammable and Hazardous Materials
Labeling must follow both OSHA’s Hazard Communication Standard (HCS) and state-specific adaptations:
Use standardized hazard pictograms
Clearly display flammability ratings and first aid info
Secondary containers must be labeled if materials are transferred from the original packaging
Labels must be legible and resistant to weathering
Some states may enforce stricter handling or storage rules, especially near schools, residential areas, or waterways.
- State-Specific Waste and Recycling Rules
Some states (like California and New York) have stricter laws for:
Labeling recyclable construction materials
Identifying treated wood waste
Documenting paint and solvent container disposal
Your ERP can help by tagging inventory by region and applying state-compliant labels automatically at the point of sale or shipping.
- Employee Training and Signage
States like California (Cal/OSHA) or Washington have specific training and signage rules for:
Prop 65 warnings (exposure to chemicals)
Signage around flammable material zones
Labeling forklifts, lifting zones, and PPE storage
Failure to post the correct signage can result in citations—even if your materials are labeled properly.
- Cross-Border (Canada–US) Considerations
Shipping between the U.S. and Canada? Make sure your labels comply with:
WHMIS (Workplace Hazardous Materials Information System) in Canada
Bilingual labeling (English and French) where required
Metric and imperial measurements, as needed
Custom forms and border documents may also require translated hazard data.
Bottom Line: Material labeling isn’t just about following rules—it’s about protecting your business, employees, and customers. Keep up with your state or provincial regulations, automate where possible, and review your labels and signage quarterly.
