Certificate of Conformance Templates
When a shipment reaches goods-in, the receiving team checks the paperwork before accepting it, and the Certificate of Conformance is the document they read, so its details have to match the purchase order and the governing standard exactly. These certificate of conformance templates set out the identification, traceability, and authorization a CoC is expected to show, with the fields and table sizing open for your parts, batches, or project handover. Pick the design that fits how you ship and fill it in.
What a certificate of conformance is for
A Certificate of Conformance, also called a Certificate of Compliance or CoC, is a signed declaration from the manufacturer or supplier that delivered goods meet the requirements stated in a purchase order, drawing, or governing standard. It is issued at dispatch and travels with the shipment, telling the receiving team that material checks, dimensional inspection, and functional testing were done before delivery. The certificate then becomes part of the buyer’s quality records, and in regulated industries such as aerospace, defense, medical devices, oil and gas, and electrical equipment it is required under standards including ISO 9001, AS9100, and IEC 61508.
These certificate of conformance templates are designed around what that document has to do at goods-in. The identification and traceability fields let a buyer match the certificate to the exact order and batch, the reference-standard fields keep it audit-ready, and the declaration and signature give it its formal weight. The designs cover product certificates for individual parts and batches and project certificates for installation and EPC handover, so the design fits the kind of shipment, and your work is entering the references that tie this certificate to this delivery.
Worth knowing: A common reason a CoC is rejected at goods-in is a revision-level mismatch. Engineering may have updated the drawing after the purchase order was raised, so the revision on the PO is not always the one the parts were built to. State the revision printed on the drawing the production line actually worked from.
Fields on a certificate of conformance
The fields a complete CoC covers across identification, traceability, and authorization.
A unique reference and the signing date. Buyers log the number into goods-receipt records so the certificate can be retrieved during audits, recalls, or warranty claims.
Legal names, addresses, and contacts for both parties, which tie the certificate to the contract long after delivery.
PO number, contract number, and line items linking the certificate to the buyer's procurement record. The link is what proves the shipment matches the order.
Part number, drawing number, and revision level for the items certified. The revision level confirms which engineering drawing version the parts were built to.
Batch or lot identifiers with the quantity shipped, tying the certificate to a specific production batch for traceability and recall handling.
Date of production and date of inspection or verification, which set warranty start points, shelf-life windows, and traceability for any later investigation.
Standards the product was made and inspected against, such as ISO 9001, AS9100, IEC 61508, or an ASTM grade. Citing them keeps the certificate audit-ready.
Core of the certificate, stating that the items meet the referenced specifications and that the inspection records are available on request.
The signatory's name, title, signature, and company stamp or seal. The signature is what makes the supplier accountable under quality management standards.
How to fill in and issue a certificate of conformance
From the design that fits your shipment to a signed certificate ready to travel with it.
Choose a design that fits what you are shipping. Per-item formats handle component and batch deliveries; project-level designs handle installation and EPC handover packages.
Place your company mark and name block, and adjust the accent color to your brand so the certificate is plainly issued by you.
Fill in both parties and the purchase order reference and line items. These are what let the buyer match the certificate to the exact order at goods-in.
Enter the part number, drawing number, revision level, and the batch or lot with the quantity shipped, so the certificate points to this exact production batch.
Tip — Use the revision printed on the drawing the production line built to, not the one on the PO, since a mismatch is a common reason a CoC is rejected.
List the standards the product was manufactured and inspected against, such as ISO 9001 or AS9100, and confirm the declaration statement matches what you are certifying.
Give the certificate a unique number, add the authorized signatory's name, title, and signature, apply the company stamp, and send it with the shipment.
FAQs
What is a certificate of conformance used for?
It acts as documented proof that the products or services delivered meet the specifications, drawings, and standards stated in the purchase order. Buyers use it during goods-in inspection, regulatory audits, warranty claims, and any later investigation into product quality.
What is the difference between a CoC and a material test certificate?
A material test certificate, such as EN 10204 3.1, lists the measured chemical composition and mechanical properties of a specific batch of raw material. A certificate of conformance is a higher-level declaration that the finished product meets all contractual and standards-based requirements. The two are often issued together for full traceability.
Does a certificate of conformance need to be signed?
Yes. An unsigned certificate is not treated as a valid quality record. The signature, with the printed name and job title of the signer, is what makes the supplier formally accountable for the declaration on the certificate.
Can the table sizing and fields be adjusted for my parts?
Yes. The certificate’s content, branding, and table sizing are editable, so you can fit the number of part numbers, batches, or line items a given shipment needs. The customizing steps above walk through each block of the certificate.
