ISO 9001:2015 Certification: How We Standardize Production

Dongguan Zhengyang Packaging & Printing Co., Ltd. passed ISO 9001:2015 Quality Management System certification for the production of paper packaging products, packaging boxes and hang tags.

Certificate details

  • Certificate No.: 19819QI4013R1S
  • Standard: GB/T19001-2016 idt ISO9001:2015
  • Initial issuance: 24 September 2019
  • Renewal: 22 February 2023
  • Expiration: 23 September 2025
  • Certification body: Beijing Xinjiyuan Certification Co., Ltd.

What changed after certification

ISO 9001:2015 is not a one-time badge. It requires annual surveillance audits and continuous improvement. On our factory floor, the standard shows up as:

  • Incoming material inspection: Every paper lot is checked for GSM, caliper and surface tension before entering production.
  • In-process checks: Color bars are pulled every 500 sheets during offset runs.
  • Final inspection: AQL sampling is applied to finished goods before carton packing.
  • Document retention: Production records are kept for at least two years for traceability.

Why buyers ask for ISO 9001

For B2B buyers, ISO 9001 is a baseline supplier qualification. It signals that the factory has documented processes, trained staff and a corrective-action system. This reduces audit risk and speeds up onboarding with large retailers and brands.

Scope of certification

Our certificate covers the production of paper packaging products including:

  • Packaging boxes
  • Hanging tags

This means our quality management system is audited specifically for the products we sell, not for unrelated activities.
