Even if the batteries are pre-installed in devices (UN3481), the internal battery cells and packs must still be fully UN38.3 certified. The outer packaging must also comply with specific drop-test safety standards.<\/p>\n<h3 id=\"faq-class-9-labeling\" style=\"color: #1e293b; margin-top: 0.8em; margin-bottom: 0.4em;\">What labeling is required on the outer shipping box?<\/h3>\n<p>Packages containing lithium batteries must display the Class 9 Lithium Battery Hazard label, the UN identification number (e.g., UN3480 or UN3481), and a cargo aircraft only label if shipping at 30% SoC via air freight.<\/p>\n<h3 id=\"faq-ocean-vs-air\" style=\"color: #1e293b; margin-top: 0.8em; margin-bottom: 0.4em;\">Are ocean freight rules different from air freight rules?<\/h3>\n<p>While ocean freight is more flexible regarding State-of-Charge (SoC) percentages, both transit methods legally require complete UN38.3 certification and detailed MSDS documents before cargo loading.<\/p>\n<\/section>\n<section>\n<h2 id=\"compliance-expert\" style=\"color: #0056b3; margin-top: 1em; margin-bottom: 0.5em;\">Meet Our Compliance Expert<\/h2>\n<p>This guide was developed in collaboration with JHY Battery&#8217;s lead regulatory compliance team.
