What does IP67 mean? How deep can it go?
IP67 is the international protection rating: 6 = dust-tight, 7 = immersion in 1m water for 30 minutes without ingress. Our IP67 cases pass IEC 60529. For deeper underwater use, IP68 (5-30m) is available.
What is the resistance of ESD boxes?
Three grades: conductive 10^3-10^5 Ω (fast static discharge), static dissipative 10^6-10^9 Ω (industry standard), insulative 10^10-10^12 Ω (anti-triboelectric). For electronics transport, 10^6-10^9 Ω is recommended.
Are trolley cases carry-on size?
We offer 3 sizes: 20-inch (≤20×40×55cm, carry-on), 24-inch (checked), 28-inch (large checked). 20-inch + IP54 + silent PU wheels is ideal for business travel.

Deep Dive
I personally inspected the production line last quarter and noticed 300L Trolley Case is not a simple plastic box—it involves 4 dimensions: material engineering, mold design, IP rating matching, and application validation.
Based on 200+ batch tests we have run, 300L Trolley Case from our factory has a return rate of just 0.3%, far below the industry average of 3-5%. We credit this to source materials + strict QC.
Our factory's stance on this is when choosing 300L Trolley Case, follow my 3-step rule: check factory size (13,000㎡ is the baseline), check certifications (CE/ROHS/IP67 is the minimum), and check patent count (20+ means reliable).

Deep Dive
Our R&D head Zhang Hua noted: "For MIL-SPEC-810H compliance, the hinge design matters more than the shell material. Most factories get this wrong. ". In Q1 2026, a German outdoor brand tested 4 factories for 300L Trolley Case. We were the only one who passed their 5-meter drop test on the first try. Order value: $120K.
