Import Tips
• Document particle size detection range (e.g
• 20nm-10μm) and throughput specs for customs review
• Obtain FDA equivalence if dual-use in pharmaceutical cleanrooms, though primarily semiconductor
• Bundle with stage adapters only if specified for wafer sizes; otherwise classify separately
