IP67 vs IP30
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IP30 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 3) and liquid protection (level 7 vs 0). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IP30 provides > 2.5 mm — tool / wire and no protection.
IP67 is dust-tight and withstands temporary immersion in water up to 1 meter for 30 minutes. The go-to rating for outdoor and rugged devices that may be briefly submerged.
IP30 protects against tools and 2.5 mm solid objects but offers no water protection. A basic indoor rating for equipment in dry, low-dust environments where only tool-access protection is required.

The exact difference (IP67 vs IP30)
Solid protection
IP67
Level 6 — Dust-Tight
IP30
Level 3 — > 2.5 mm — Tool / Wire
IP67 provides "Dust-Tight" (level 6), while IP30 provides "> 2.5 mm — Tool / Wire" (level 3). IP67 is 3 levels higher.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP30
Level 0 — No Protection
IP67 provides "Temporary Immersion (up to 1 m)" (level 7), while IP30 provides "No Protection" (level 0). IP67 is 7 levels higher.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP30. Choose IP67 for harsher environments; IP30 may suffice for milder conditions and can be more cost-effective.
