IP67 is an ingress protection rating per IEC 60529. The 6 = completely dustproof, the 7 = protected against temporary water immersion (1m depth for 30 minutes). It is the most common rating for industrial, military, and outdoor protective cases. To learn more, see our full IP67 buying guide with material comparison and OEM pricing.
Complete IP67 protective case buying guide: IEC 60529 rating, material comparison (PP/ABS/PC), use cases, OEM/ODM, source factory pricing. 2,500+ words.
If you are evaluating protective cases for industrial, military, or outdoor applications, you have almost certainly encountered the term "IP67." But what does IP67 actually mean, when do you need it, and how do you choose a reliable supplier? This guide, written by the engineering team at KeXinMaterials (Zhongshan Junzhijia) — a source factory with 12 years of experience manufacturing IP67-rated cases for B2B buyers across 50+ countries — walks you through every step of the decision.
By the end of this 2,500+ word guide, you will understand the IEC 60529 standard, the difference between IP67 and MIL-SPEC, the trade-offs between PP, ABS, and PC materials, and the OEM/ODM process for custom IP67 cases. You will also see real factory pricing, lead times, and a checklist you can hand to your procurement team.
Key fact: KeXinMaterials produces 150+ IP67-rated SKUs across 9 product lines — from drone cases to medical cold-chain cases — and ships globally to USA, EU, Japan, and emerging markets.
The "IP" in IP67 stands for Ingress Protection, a rating system defined by the international standard IEC 60529 (also adopted as EN 60529 in the EU and GB/T 4208 in China). The standard was first published in 1976 by the International Electrotechnical Commission and has been revised multiple times, with the current 2013 edition still in force.
An IP rating always has two digits (or an "X" when a rating is not specified):
So IP67 specifically means: completely dustproof (level 6) AND resistant to temporary water immersion (level 7). It is the most common rating you'll see on B2B protective cases because it strikes a balance between sealing performance, cost, and usability.
It is important to understand that IP67 is not the highest water rating. The progression is:
For most industrial, military, and outdoor applications, IP67 is the sweet spot. IP68 adds cost and weight for marginal real-world benefit unless you specifically need continuous underwater use (e.g., diving equipment housings).
IP67 and MIL-SPEC are not competing standards — they measure different things. IP67 is a single test focused on dust and water ingress. MIL-SPEC (specifically MIL-STD-810) is a family of 30+ environmental tests covering drop, vibration, temperature, humidity, fungus, salt fog, sand, and more.
Here is a practical comparison:
| Test | IP67 | MIL-STD-810H |
|---|---|---|
| Dust ingress | 8 hours dust chamber | Up to 90 days blowing sand |
| Water immersion | 1m / 30 min | Rain, splash, immersion (variable) |
| Drop test | Not required | 26 drops from 1.2m on all faces |
| Vibration | Not required | Random & sinusoidal, 3 axes |
| Temperature | Not required | -40°C to +70°C operating |
| Cost impact | +15-20% vs basic case | +50-100% vs IP67 |
If your equipment is used outdoors and might get rained on, IP67 is sufficient. If your equipment is used by military, police, fire, or in aerospace, MIL-SPEC is required. Many of our clients specify IP67 + MIL-STD-810 drop as a balanced requirement.
Note that MIL-SPEC cases almost always include IP67 or higher sealing as a baseline. So when evaluating a MIL-SPEC case, ask for the specific IP rating — don't assume.
The three most common materials for IP67 protective cases are PP (polypropylene), ABS (acrylonitrile butadiene styrene), and PC (polycarbonate). Each has distinct trade-offs.
For the best of all worlds, many premium cases use PP+GF (polypropylene with glass fiber) for the outer shell and a softer TPU seal for the gasket. This is what our Series 8 line uses — achieving IP67 at -40°C to +120°C with a 100kg+ load capacity.

IP67 is a rating from the IEC 60529 international standard. 'IP' = Ingress Protection. The '6' means completely dustproof. The '7' means resistant to temporary water immersion (1m depth for up to 30 minutes).
IP67 can withstand temporary water immersion. IP65 can only withstand low-pressure water jets. IP67 is suitable for outdoor and marine environments; IP65 is sufficient for rain exposure.
PP is lightest, most chemical-resistant, and food-safe. ABS is harder, glossier, and easier to color-match. PC is strongest and most premium but costliest. For most applications, ABS offers the best balance.
At KeXinMaterials, standard SKUs are available from 50-100 pcs. Custom OEM/ODM orders start at 300 pcs.
Sampling: 7-10 days. Mass production: 15-25 days. Sea freight: 25-40 days. Total: 30-45 days from deposit to your warehouse.
