Standards (ISO, HACCP, etc.) are applied voluntarily; only technical regulations are mandatory (2006 Law on Standards and Technical Regulations, amended by Law No. 70/2025/QH15). Enterprises obtain certification because customers, bidding documents or supply chains require it.
| Certification | Used for |
|---|---|
| ISO 9001 | Quality management, all sectors |
| ISO 14001 / ISO 45001 | Environment / occupational health and safety |

Certification does not replace permits: the fire prevention and fighting (PCCC) dossier, permits and environmental registration are still done separately. For food in particular: a facility with a valid GMP, HACCP, ISO 22000, IFS, BRC or FSSC 22000 certificate is not subject to the Food Safety Certificate (point k, Clause 1, Article 12 of Decree No. 15/2018/NĐ-CP), but must still meet the food safety conditions.
