SummaryBlue Sky is explicitly identified as a professional technical supplier providing 3D software design and broad customization services for filtration products. Its engineering and sales teams support product design and development, while quality processes include two inspectors, documented finished-product inspection instructions, raw-material traceability, and quality assurance. It holds ISO9001:2015, ISO45001:2018, ISO14001, and RoHS-related certification capability. Production-related evidence shows gluing, paper folding, and assembly lines, plus in-stock capacity, but no valid manufacturing-capacity contract with associated subcontractors. The supplier lacks an available SDK, overseas agents or branches, overseas warehouses, and overseas showrooms. Lead times are stated as within 15 working days in both peak and off-season.
