Information for Suppliers

Dear Supplier,


In order to fulfil the requirement 8.4.3 of the ISO 9001:2015 Standard, we hereby inform you of Sentinel’s requirements to guarantee the quality and conformity of the products and services we receive. We therefore inform you that:

  • An initial assessment is carried out to select and approve all suppliers;
  • The performance of all suppliers is monitored and evaluated on an annual basis.


To this end, the evaluation takes into account 5 parameters:

  • Quality
  • Payment terms
  • Response times
  • Delivery times
  • Price level


Suppliers are classified into three categories:

  • A – Preferred supplier (Score ≥ 15)
  • B – Sufficient supplier (8 ≤ Score ≥ 14)
  • C – Risk supplier (7 ≤ Score)


Orders from suppliers with a lower score, classified in category C, will be suspended and a reassessment will be carried out after 6 months.

*If you are ISO 9001:2015 certified, please send us a copy of your current certificate.
