From Tyre Markings to Material Certificates: How to Review a Railway Tyre Inspection Pack

8 November 2026

A railway tyre inspection pack is most useful when the buyer can tell which products each document covers. A dimensional report may contain acceptable readings, and a material certificate may list the specified grade, but both still need to be linked to the products being shipped.

Kingrail’s published inspection example for 650 railway tyres lists SGS checks covering quantity, markings, packing, visual condition, dimensions, hardness and material certificates. Buyers can use that scope to see how different records work together when reviewing a shipment.

Start with the order and drawing revision

Check the part number and drawing revision on the inspection report against the approved order documents. Then check that the report identifies the characteristics inspected and the acceptance criteria used. When a shipment contains similar tyre profiles or more than one drawing revision, review each group separately so that records for one type are not mistaken for another.

Match the markings to the material records

Identify which markings connect the tyres to their material documentation. Depending on the purchase specification, this may be a heat number, batch identifier, individual serial number or a combination of identifiers.

Check that the identifiers visible on the products, or recorded in a traceability list, lead to the relevant material certificates. If a certificate covers more than one heat or production batch, confirm which entry applies to each group of tyres. Agree the required level of traceability before production; batch identification and individual identification serve different purposes.

Distinguish shipment quantity from inspection coverage

A shipment quantity describes how many items are supplied. It does not, by itself, show how many pieces were measured or hardness tested. Read each inspection line separately: what was checked, what population it covered, and whether the check was performed on every item or on an agreed sample.

The same distinction applies to third-party inspection. A report should be read against its stated scope and the order requirements. If a required characteristic is missing or its coverage is unclear, resolve that point before relying on the report for shipment release.

Check the link to the packing list

For a shipment packed across several crates or bundles, the packing list should make it possible to locate each product group on receipt. Where required, use a packing record that connects each package identifier to the relevant part number, quantity and batch or serial information.

For example, if two tyre batches are shipped in separate crates, the receiver should be able to identify the batch in each crate without opening every package or guessing from its position in the container.

Agree on the records before production

State the required markings, material documents, inspection coverage and packing records in the purchase specification. If an independent inspection is required, define its scope and identify any records the inspector needs to review. Agreeing these details early makes it easier to assemble a document pack that the buyer can use both for shipment review and for goods receipt.
