Here\u2019s what they mean:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>IP54<\/strong> \u2192 Entry-level, splash and dust resistant.

Ideal for delivery or cargo bikes in urban rain.<\/li>\n\n\n\n<li><strong>IP67<\/strong> \u2192 Dust-tight, immersion resistant up to 1 m.

While the standard does not always demand a specific IP number, manufacturers must prove safety and reliability under typical use conditions\u2014including rain, puddles, and dust exposure.<\/p>\n\n\n\n<p>For distributors and importers, checking the <strong>Declaration of Conformity (DoC)<\/strong> and associated <strong>test reports<\/strong> is critical.
