Exiting a Supplier Without Breaking the Programme

The Problem: Transitions Fail for Predictable Reasons

Suppliers are changed for good reasons: price, quality, capacity, a factory closing, an owner retiring. The failure that follows is also predictable. The new supplier produces something nearly identical — a body half a millimetre different, a glaze a shade lighter, a carton that no longer fits the pallet — and the buyer discovers it in front of a customer. Nothing about that is mysterious; it happens because the specification lived in the head of the previous supplier rather than in a document, and because the transition was treated as a purchase rather than as a project.

Where This Fits in the Sourcing Chain

A clean exit depends on a specification package that exists before the exit is needed. The spec freeze guide explains how artwork and packing files are locked between orders. It also depends on tooling and artwork, which are physical and legal assets rather than data. The packaging guide explains how retail-ready and protective layers are specified together. The full chain follows the standard sourcing map. See the full ceramic sourcing process map.

The Specification Package

Six items, and a buyer who holds all six can change suppliers without touching the product.

A written specification per item: capacity, dimensions, weight, wall thickness tolerance, material, glaze type and finish.

A sealed golden sample per item, held by the buyer, dated and signed.

Glaze and colour references — the recipe is the factory's, but the fired standard is the buyer's.

Decoration artwork in a usable format, with the print method named.

Packaging specification, including carton dimensions, board grade, units per carton and the pallet pattern.

The carton and label artwork, which is frequently forgotten until the first shipment without it.

Tooling: The Part That Gets Contested

Moulds and printing plates are physical assets, and their ownership belongs in the original agreement rather than in the argument that follows a break-up. Three positions exist: the buyer owns and holds the tooling, the buyer owns it and it stays at the factory, and the factory owns it and the buyer licenses nothing. Each has consequences — the first two allow a move, the third does not — and the practical advice is to decide at the beginning, in writing, including who pays for maintenance and what happens to the tooling at the end.

Where the tooling cannot move, the realistic alternative is a new tool developed to the specification, using the golden sample as the target — which is a genuine cost and should be budgeted as part of the transition rather than discovered within it.

The Transition Plan

Four phases, and the overlap between them is what keeps supply continuous.

Qualify first. The new supplier produces samples against the specification and the golden sample, and those samples are approved before any commercial commitment.

Run in parallel. Both suppliers produce for one cycle, so that the new source proves itself while the old one still covers demand.

Last-buy deliberately. Agree a final order with the outgoing supplier sized to cover the overlap plus a buffer for the transition — not to cover the year, since a large last-buy becomes dead stock if the transition goes well.

Hand over documentation, including open orders, artwork files, packaging specifications and any certification the market requires.

The Exit Terms to Agree Early

Four clauses, all cheap to negotiate while the relationship is good. Tooling ownership and transfer. Confidentiality, particularly on artwork and any buyer-specific design. Obligations on open orders and how they will be completed. And a notice period, because an exit announced in a week is an exit that damages both sides.

The Other Direction

Suppliers face the same discipline. Dropping a customer — for commercial reasons, capacity, or because of payment behaviour — should follow the same logic: notice, specification handover, completion of agreed orders, and an honest statement about the tooling. A supplier who exits well is described well, and in a market where buyers talk to each other, that is worth more than the margin on one account.

The Habit That Ties It Together

The habit is to prepare for the exit while the relationship is working. Programs that do this change suppliers without changing the product — which is the only outcome that matters.
