Suppliers
Working with ESM
Our purchasing conditions, what we expect from a supplier, how we select and evaluate, and how to present your company. Everything on this page applies to every order we place.
Conformity to the order
The supplier guarantees full compliance with the purchase order. Any deviation not declared at order acknowledgement may lead to rejection on receipt.
Declare early, not late
A deviation raised at acknowledgement is a discussion. The same deviation discovered at receiving inspection is a non-conformity.
Receiving hours
08:00–12:00 / 13:00–17:00. Early deliveries may be refused and returned at the supplier's expense.
One quality system
Suppliers work inside an EN 9100 and ISO 9001 certified system. Customer requirements are flowed down contractually, not informally.
General purchase conditions
The terms that govern our orders
ESM's General Purchase Conditions are issued under document reference R01-P03-F01 and accompany every purchase order. Accepting an ESM order means accepting them.
The clauses reproduced here are the ones a supplier needs before the first delivery. They do not replace the complete document, which is sent with the order and is available on request.
Reference R01-P03-F01 · ESM — Engineering Solution and Machining · Share capital 3,400,000 TND · Industrial Building No. 4, Cité El Mzoughi, Bir El Kassaa, Ben Arous, Tunisia.
Receiving hours: 08:00–12:00 / 13:00–17:00. Early deliveries may be refused and returned at supplier's expense.
The supplier is responsible for full compliance with the purchase order requirements. Any non-declared deviation may result in rejection upon receipt.
For any questions, please contact your usual ESM representative, or write to achat@esm.com.tn for purchasing and payment matters. Invoices are submitted only through the ESM supplier invoice portal.
Already an ESM supplier and you have lost your copy of the conditions? Ask your buyer — the document is re-issued with any order.
Supplier quality requirements
What we expect from you
Quality management system
A documented quality system, proportionate to the commodity supplied. ISO 9001 as a minimum for production commodities; EN 9100 or a recognised process accreditation where the product or process feeds an aerospace part.
Traceability
Batch or heat identification maintained from your own source through to delivery, with certificates matching the material or process actually supplied.
Documentation with the delivery
Certificate of conformity, material or process certificates and inspection records delivered with the goods. A delivery without its documentation is not a delivery.
Flow-down of customer requirements
Requirements transmitted by ESM — specifications, key characteristics, special process approvals, right of access — are contractual and must be flowed down to your own sub-tiers.
Change and deviation control
No change of process, source, site or sub-tier without prior written notice. No concession without a formal request. Silence is not agreement.
Non-conformity response
Containment on notification, root cause analysis and a corrective action plan. Structured problem solving is expected, not an apology.
Packaging and preservation
Protection appropriate to the part, clear identification on the outside of the package, and foreign object prevention applied to what you ship.
On-time delivery
The confirmed date is the commitment. A date at risk must be signalled as soon as it is known, not on the day it is missed.
Right of access
ESM, its customers and regulatory authorities may access your facilities and the applicable records for the work performed on our orders.
Process S01
Selection, evaluation, development
Purchasing and supplier development is a mapped process of our quality system, with a named owner, measured objectives and a review cadence. Its purpose is to guarantee the conformity of everything that enters an ESM part.
Selection
Assessment against documented selection criteria: quality system, technical capability, capacity, references and the commodity concerned.
Contractualisation
Generic supplier requirements and the applicable customer requirements are transmitted and accepted before the first order.
Receiving control
Every delivery is inspected on receipt: documentation, identification and conformity to the order before entering stock.
Continuous monitoring
Performance is measured on delivery compliance, quality compliance and responsiveness, and reviewed monthly.
Periodic re-evaluation and audit
Suppliers are re-evaluated through formal questionnaires and audited on a published plan by our internal or external audit resources.
Classification
Results drive the supplier classification, which determines order volume, inspection level and development actions.
Measured on
Delivery compliance · quality compliance · ESM satisfaction with the supplier.
Reviewed by
Purchasing, process owners, audit, receiving inspection, methods and engineering.
Against
ISO 9001 and AS 9100 / AS 9102 requirements.

Invoices are submitted in PDF on the ESM supplier invoice portal and must carry the ESM purchase order number. An invoice without its order reference cannot be matched and will delay payment. Failing the portal, the invoice may be emailed to purchases@esm-tunis.odoo.com; paper invoices and invoices sent to any other address are not processed.
Questions on an order in progress go to your usual ESM buyer, not to the general mailbox — it is faster and the file stays with one person.
If you are a special process provider — surface treatment, coating, heat treatment, non-destructive testing — tell us which approvals you hold and for which customers. That is the first question we will ask.
Become a supplier
Present your company
Tell us what you supply, which approvals you hold and who your aerospace references are. Applications are reviewed against our selection criteria by the purchasing and quality teams together.
Use the same form to request the complete General Purchase Conditions.
We are particularly interested in qualified providers of surface treatment, coating, heat treatment and non-destructive testing, and in aerospace aluminium stockholders.
Contract documents
What you sign before the first delivery.
Both documents are published in full, in French and English. The French version prevails. They are referenced on every purchase order and provided again with the qualification package.
