Quality and management evidence includes ISO9001:2015, ISO14001, and ISO45001:2018 certifications, documented inspection procedures, corrective-action processes, and complaint-handling procedures. Manufacturing-related data indicates 12 production lines, but the supplier does not continuously reconcile quantities for every batch or production volume. Export experience is established, with 22 years of exporting and 71%–90% of sales from exports. Overseas infrastructure is limited: it has no overseas warehouse, showroom, agent, or branch, and reports zero countries served overseas. Financial records are indicated for 2022–2024, but no detailed financial results are provided. Customer-specific evidence is limited to stated OEM service for well-known brands.

CertificationsThe supplier reports ISO9001:2015, ISO14001, and ISO45001:2018 certifications, supported by stated environmental assessment documentation and recent fire-drill activity.
