A factory in Vietnam can have dozens of suppliers for things that never appear on a bill of materials: end mills from one shop, bearings from another, gloves from a third, and a belt bought in a hurry when a line stops. Each supplier sends its own quotation, invoice and delivery. The purchasing team spends more time on the small lines than on the raw materials, and still runs out of the one part that stops production.
Putting maintenance, repair and operations (MRO) consumables through one supplier fixes this only if the factory first knows what it buys. This guide sets out the order of work: build one item list, decide what each line needs in stock, then choose how orders and deliveries run.

Start with one item list, not with a supplier
Before you consolidate suppliers, build one item list in which every consumable has a full specification, the maker’s part number where one exists, a unit of measure and a named user, because a supplier cannot quote or stock a line that the factory itself describes in three different ways.
In most factories the same item lives under several names. Maintenance calls it “bearing 6205”, the stores team calls it “bearing small”, and the last purchase order says “ball bearing 25 mm”. Before any supplier is involved, merge these into one line. The table below is the minimum each line needs.
| Field | Example of what goes in it | Why it matters |
|---|---|---|
| Item code | Your internal code | One code per item, used by stores, purchasing and accounts |
| Description in a fixed pattern | ”Deep groove ball bearing, 25 x 52 x 15 mm, double shielded” | Two people describe the same item the same way |
| Maker and full part number | The number printed on the part or box, with every suffix | The suffix often carries the seal, clearance or grade |
| Approved alternatives | Other makers’ numbers the engineer has accepted | Lets a supplier offer a second source without a new approval each time |
| Unit of measure | Piece, box of 10, roll, pair | Prevents a box being priced as a piece |
| Machine or area where it is used | Line 3 press, CNC cell, packing | Tells you how critical the line is |
| Annual use, from your own records | Taken from past issues or purchase orders | The base for stock levels and for a supplier’s planning |
| Technical owner | Name of the engineer who approves changes | Someone must sign off a substitute |
The part number is where most errors start. For bearings, belts, chains and cutting tools the number encodes the size and much of the specification. How to read those numbers is set out in bearings, belts and chains and cutting tools and abrasives.
Group the list by category
Once the lines are clean, group them. A grouping that matches how the goods are bought works better than one that matches the accounts:
- cutting tools and inserts, drills, taps;
- abrasives: grinding wheels, cut-off discs, sanding belts and sheets;
- bearings, belts, chains, couplings and seals;
- personal protective equipment: gloves, safety shoes, eyewear, hearing protection;
- lubricants, cleaning chemicals and absorbents;
- fasteners and small hardware;
- electrical consumables: fuses, relays, cable ties, lamps;
- packing materials used in the factory itself.
Each group has its own risks. Abrasives and PPE carry safety markings that must match the market. Bearings and cutting tools are copied. Lubricants and chemicals may need a safety data sheet and may be restricted in transport.
Decide what each line needs in stock
Classify every line by what happens if it runs out, then set a minimum and maximum stock for it from your own usage and the supplier’s replenishment time, so that critical spares are held and low-risk lines are bought only when needed.
A simple three-way split is enough for most factories:
| Class | What it means | Typical items | Stock approach |
|---|---|---|---|
| Critical | A stock-out stops a machine or a line | Bearings and belts for key machines, specific inserts for a production part | Hold on site, with a minimum level and a named person who reorders |
| Regular | Used every month, a short stock-out is a nuisance | Gloves, abrasives, common drills, cable ties | Reorder at a minimum level, delivered on a fixed cycle |
| Occasional | Used rarely, no line stops without it | Special tools, items for one project | Buy when needed, no stock |
The minimum level for each line comes from two numbers you already have or can get: how many the factory uses in a period, and how long the supplier takes to replace it. Neither number should be guessed. Use your own issue records for the first. Ask the supplier for the second, line by line, because a common glove and an imported bearing will not have the same replenishment time.
Two points are easy to miss:
- Shelf life. Some consumables age: adhesives, sealants, some rubber goods, and some lubricants. Record the shelf life and issue the oldest stock first.
- Packaging unit. If a disc is sold only in boxes of a fixed count, the minimum level should be set in boxes, not pieces.
Choose how orders and deliveries run
A consolidated MRO supply works when the factory places one regular order against the agreed item list, the supplier delivers to a fixed schedule with one delivery note by item code, and urgent lines have a separate, agreed route.
There are three common ways to run it. They can be combined.
| Model | How it works | Suits |
|---|---|---|
| Regular consolidated order | The factory sends one order on a fixed cycle covering all lines below their minimum | Most regular lines |
| Agreed list with call-offs | Specification and alternatives are agreed in advance; the factory calls off quantities as needed | Lines used often in varying amounts |
| Supplier-checked stock | The supplier checks agreed stock points on site and proposes the reorder | Factories that want to take counting off the stores team |
Whichever model you use, settle these points in writing before the first order:
- The item list is the contract. Anything not on the list is a separate quotation. This stops the list growing without approval.
- Substitutes need approval. If an approved part is unavailable, the supplier proposes an alternative from the approved-alternatives column or asks the technical owner. No silent substitutions.
- Price review timing. Agree when prices on the list are reviewed, so a quotation does not have to be negotiated on every order.
- Delivery documents. One delivery note listing item code, part number, quantity and packaging unit, matching the order line for line.
- Urgent orders. Agree how a breakdown order is placed out of cycle and who can approve it.
💬 Want one regular order instead of many small ones? We work from your item list, source each line in Vietnam or abroad, and deliver against your item codes. See MRO and factory consumables.
Where each line comes from
One supplier on your side does not mean one source: some lines are bought in Vietnam, some are imported, and the supplier’s job is to keep the specification, the paperwork and the delivery the same either way.
A factory’s list usually mixes three kinds of line:
- Lines available in Vietnam. Common PPE, abrasives, fasteners and many bearing and belt sizes are stocked by distributors here.
- Lines specified by a foreign maker’s part number. Inserts, special bearings or a belt for an imported machine may have to be brought in. Where the part is Japanese and must be the maker’s genuine part, the route is set out in genuine Japanese industrial parts.
- Lines where an equivalent is acceptable. If the engineer has approved an alternative, the supplier can buy whichever approved source is available.
For imported lines, consolidation also happens at the origin end. Buying from several suppliers abroad and shipping once is covered in consolidating Asian suppliers into one shipment.
Two points depend on your factory’s own status, and you should confirm them with your customs broker and accountant rather than assume:
- If your factory is an export-processing enterprise or operates under a special customs regime, how a purchase from a supplier in Vietnam is declared and invoiced may differ from an ordinary domestic purchase.
- Imported lines carry import duty and VAT according to their own tariff headings. A box described only as “spare parts” invites questions; each line should be classified.
Receiving, checking and counterfeit risk
Check every delivery against the item list, not against the supplier’s invoice: part number, maker, packaging unit and quantity, plus the labels and markings that show the item is what it claims to be.
The receiving check for consumables does not need to be heavy, but it must be consistent:
| Check | What to look for |
|---|---|
| Part number and maker | Exactly as on the item list, including suffixes |
| Packaging | Maker’s original packaging, intact, with lot or date codes where the maker uses them |
| Safety markings | On PPE and abrasives: the standard and marking your market requires |
| Documents | Delivery note matching the order line by line; certificates where the item list asks for them |
| Quantity and unit | Boxes versus pieces, pairs versus single gloves |
Bearings, cutting tools and some PPE are copied, sometimes well. Buying through a channel you can trace back to the maker, and using the maker’s own verification tools where they exist, is the defence. Both are set out in avoiding counterfeit bearings and industrial parts. PPE markings by market are covered in safety gloves, shoes and eyewear.
For lines where a defect would be expensive, a documented incoming check works the same way as for production parts. The documents to ask for are listed in quality documents for parts from Vietnam.
How to start without changing everything at once
Start with one category that causes the most trouble, run it through one supplier for a few order cycles, check the results against the item list, and only then add the next category.
A practical sequence:
- Export your last year of purchase orders for consumables.
- Clean them into one item list with the fields above.
- Mark the critical lines and agree approved alternatives with the engineers.
- Pick one category, often cutting tools, abrasives or PPE, and ask for a quotation against the list.
- Run it for several cycles and measure what you care about: stock-outs, number of invoices, time spent by purchasing.
- Add the next category.
The supplier needs the same information every time: the item list, the usage, the critical lines and the delivery address. Prices are only comparable once every supplier has quoted the same list. How to compare quotations line by line is set out in comparing supplier quotations.

Frequently asked questions
1. What counts as MRO in a factory?
Maintenance, repair and operations items: the consumables and spares a factory uses to keep running but that do not become part of the product. Typical lines are cutting tools, abrasives, bearings, belts, PPE, lubricants, fasteners and electrical consumables.
2. Do I need to change all my suppliers at once?
No. Start with one category, run it through one supplier for a few order cycles, check stock-outs and invoices against the item list, then add the next category.
3. Can one supplier source both imported and locally available items?
Yes. A trading company buys each line where the approved specification is available, in Vietnam or abroad, and delivers against your item codes with one set of documents.
4. How are stock levels set for each consumable?
From your own usage records and the supplier’s replenishment time for each line, with critical lines held on site at a minimum level. Shelf life and packaging units should be built into the level.
5. What happens when an approved part is not available?
The supplier proposes an alternative from the approved-alternatives list, or asks your technical owner to approve a new one. Substitutions without approval should be ruled out in writing.
