Korean plants will not specify equipment they cannot get a part for within the week

Your equipment is technically better and priced competitively, and it still does not appear in the specification. Somewhere in the evaluation, a maintenance engineer asked how long a replacement part takes to arrive. The answer was four to six weeks, and that ended it — not because anyone said so, but because the item quietly stopped being proposed.

Downtime is priced, and it is priced high

In continuously operating plant — petrochemical, steel, power, semiconductor — a stoppage is measured in lost production per hour. On a large unit that figure can exceed the value of the equipment within a single day.

Maintenance functions work against that number. When they assess equipment, availability of parts is not a service consideration; it is an arithmetic input. A component with a six-week replacement time carries an implied risk cost that a comparable component with a two-day replacement time does not.

This is why a lower purchase price frequently loses. The comparison being made is not price against price, but price plus expected downtime exposure against the same for the alternative — and that second term dwarfs the first.

The same logic explains why brownfield work is harder to win than new build. On a new plant the risk is theoretical; on an operating one the maintenance team has lived through a waiting period and can name the date. An organisation that has been stopped once by a part in transit applies that memory to every subsequent specification, and it does not distinguish between the supplier responsible and the category.

Where the objection is actually raised

You rarely hear it, because it is not raised in a conversation with you. It appears in an internal opinion requested from maintenance during technical evaluation.

That opinion is short — often a few lines — and it carries weight disproportionate to its length, because nobody in the room wants to override the function that will be called at three in the morning. A negative note there is not framed as a rejection; it is framed as a risk, which is harder to argue with.

The consequence is that the argument has to be won before the evaluation, in material that reaches maintenance directly. By the time the evaluation is running, you are not in the conversation.

Which parts the question is really about

Not every component needs to be locally available. Treating the requirement as all-or-nothing makes it look impossible, when it is actually narrow.

The first row is usually a handful of items: a seal set, a sensor, a control card, a coupling. Establishing availability for those few changes the assessment entirely, and it costs a fraction of holding a full parts range.

Stock is not the only answer

"Local stock" is one solution among several, and it is the most expensive. The requirement is a response time, not an inventory location.

The alternatives are worth knowing. Sell the critical set with the machine, so the parts sit in the customer's own store from day one — simplest, and it converts the issue into a line on the order. Consignment at the customer, where stock is held on site but invoiced on use. Regional stock, where a partner in Korea holds the fast-moving items.

Each has a different cost and a different credibility. What does not work is an assurance of air freight, because air freight does not shorten customs clearance, and it is the clearance step that maintenance has experienced as unpredictable.

Clearance is part of the answer

A part that ships overnight and then sits for four days at import is a five-day part. Buyers know this from experience, and a delivery promise that ignores it is read as inexperience.

Two things shorten the customs step, and both are preparation rather than speed. The classification of your parts should be settled in advance, so that each shipment is not a fresh determination. And where a part falls under an import requirement, the confirmation should exist before the emergency, not during it.

Saying this explicitly is persuasive precisely because most suppliers do not. "Two days from our warehouse plus clearance, which we have pre-cleared for these part numbers" is a different statement from "we ship within 24 hours".

The parts list is the document that gets read

Maintenance does not read your brochure. They read a parts list, and its quality is taken as a signal of how the relationship will work.

What makes it usable: part numbers that will still resolve in five years, a clear split between wear items and repair items, recommended quantities tied to running hours, and lead times stated per item rather than as a single figure. Interchange information — where a bearing or seal is a standard commercial item — is read as honesty rather than as a lost sale.

Supplying this list at quotation stage, before anyone asks, puts a document in front of the function whose opinion decides the matter. It is one page of work against a decision you otherwise cannot reach.

Numbering has to survive the handover

A practical failure mode: the parts are available, but nobody can order them. The customer's maintenance system holds its own item numbers, created at handover from whatever documentation arrived.

If your parts list uses internal drawing numbers that do not appear on the components, or if the same item is named differently across documents, every future order starts with an identification exchange. Two or three of those, and the part is quietly replaced with a locally sourced equivalent.

Providing the list in a form that loads into the customer's system — consistent numbering, descriptions that match the nameplate, and a note on which items are commercially standard — is unglamorous and it keeps the aftermarket with you.

The first reference is where this is proven

Claims about response time are discounted until there is a case. That case does not have to be in Korea, but it has to be specific.

What carries: a described incident — what failed, when it was reported, when the part arrived, when the plant restarted. Four timestamps. This is more convincing than any commitment, because it describes what happened rather than what is intended.

If you have no such case yet, the honest version still works better than a promise: state the stock location, the routing, the customs status of the part numbers, and what you will commit to contractually. Maintenance engineers are used to assessing arrangements; they are not used to being told that nothing will ever break.

What becomes the constraint once parts are solved

Assume the parts question is answered and your equipment enters the specification. The next limit is not commercial — it is diagnostic.

A part on site is only useful if someone can determine that it is the part that failed. Where fault-finding requires the manufacturer's software, a proprietary interface, or an engineer who knows the machine, the response time reverts to travel time regardless of where the stock sits. Maintenance departments have encountered this, and on the second occurrence it affects the next specification.

So the work that follows availability is diagnostic autonomy: fault codes that mean something without a manual only you hold, a troubleshooting sequence that the customer's own technicians can follow, and access to whatever tool is needed to read the machine. That is what turns a stocked part into a short stoppage. If you can name your critical items and the plants you are targeting, we can look at what availability has to look like for that category — talk to us about sourcing.
