OSHA-compliant containers are essential for businesses handling hazardous chemicals in the United States. The Hazard Communication Standard has specific expectations for labels, and the 2024 update introduced clearer rules for small containers.
UK exporters and global manufacturers should understand these rules when products are sold or handled in US workplaces.
What changed for small containers
For containers of 100 ml or less, OSHA expects the immediate container to show the product identifier, pictogram, signal word, manufacturer name and phone number, plus a statement directing users to full label information on the outer packaging.
For containers of 3 ml or less, the immediate container may show only the product identifier, while the outer container must carry the full label information and storage statement.
Why this matters to packaging lines
Small containers create practical labelling challenges. The label area may be too small for full hazard text, pictograms, batch codes, barcodes and branding. A packaging line may therefore need wrap-around labels, peel-back labels, tags or an outer pack with complete hazard information.
Machinery options for compliant labelling
Label applicators, print-and-apply systems, small-container handling, vision inspection and coding equipment can all help improve compliance. For very small packs, product orientation and label accuracy are critical.
Exporter checklist
Confirm the destination market, product classification, label elements, outer packaging requirements, barcode and batch coding, inspection method and whether the line must reject missing or misapplied labels.
