Trolley MOQ and Lead Time Explained | Doing Metal

Minimum order quantity is one of the first questions a buyer asks a custom trolley manufacturer, and it is often answered with a flat number that means very little. The honest answer depends on what has to happen before the first weld: how much fixturing the design needs, whether new material sizes must be bought in, and how much line time the job occupies. Understanding those drivers lets you plan around MOQ instead of fighting it.

Why a custom cart has a minimum quantity

Every new design carries setup that is identical whether you build ten units or ten thousand:

• Engineering: drawing review, DFm feedback, sometimes a revised drawing set
• Fixturing: welding jigs, bending setups, hole templates or laser nests
• Line setup: tooling changes, proof welds, first-piece inspection
• Finish setup: powder coat colour changeovers cost time and powder, so very short runs are priced accordingly

Those costs are fixed. Spread across 200 units they are negligible; across 10 units they dominate the unit price. That is why standard custom programmes normally begin around 50 units, while larger or heavy-duty projects with more structural content can sometimes be discussed from 10 units after review.

What actually drives lead time

Lead time for a built-to-drawing cart has four parts, and only one of them is welding:

1. Engineering and quotation. Usually one to two days once the RFQ is complete. Incomplete route, floor or load information is the usual delay.
2. Material. Common tube and sheet sizes are stocked; unusual sections, specific stainless grades or thick plate may need sourcing time.
3. Production. Cutting, forming, welding, finishing and assembly. Complexity and quantity both matter, and the finish queue is often the longest wait in the building.
4. Inspection and packing. Dimensional checks, function checks, packing, container booking.

Sea freight from Ningbo adds weeks depending on destination. Buyers who plan a trolley rollout backwards from a launch date usually start talking to manufacturers two to three months before they need carts on the floor.

How to plan a repeat programme

The best time to discuss the second order is during the first quotation, because several decisions are cheaper when made together:

• Standardise the finish. One colour across the programme avoids repeated line changeovers.
• Standardise the casters. A common wheel specification simplifies spares for your own service team.
• Keep the drawing on file. Drawings and jigs held by the manufacturer make year-two orders match year-one geometry.
• Order spares with the first batch. Additional wheels, handles and brake assemblies cost little in the same container and save an air-freight emergency later.

Distributors running an OEM or private-label programme benefit most from this approach: consistent geometry lets you publish your own catalogue spec without re-engineering each order.

Ten questions worth asking any trolley supplier

Before committing, ask these – the answers tell you more about the factory than any brochure:

1. Is the quoted MOQ per model or per order?
2. What happens to tooling if we repeat in twelve months?
3. Which parts of the cart are made in-house versus bought in?
4. Can we get a first article before the batch runs?
5. What inspection records come with the shipment?
6. Is packing included, and how many units per container?
7. Can the cart be knocked down to reduce freight?
8. What are the spare-part lead times for wheels and brakes?
9. How are finish colours controlled between batches?
10. What changed on the last repeat [programme] they shipped, and why?

Planning backwards from your launch date

The shortest way to miss a rollout is to start calling factories once the floor is ready. A realistic sequence for a new cart programme looks like this:

1. Three months out: requirement defined, RFQ sent with complete information
2. Three months out: quotation reviewed, drawing agreed, any design-for-manufacture changes confirmed
3. Two months out: first article produced where the programme justifies it, tested on the real route
4. Two months out: batch production, inspection, packing
5. Booking and sailing: several weeks from Ningbo depending on destination
6. Destination: customs clearance, inland delivery, assembly if knocked down

Buyers who build this timeline before contacting suppliers rarely pay for expedited freight, which is the most expensive line item in any late programme.

How to lower unit price without degrading quality

Unit price responds to decisions that cost nothing in performance:

• Standardise the finish. One colour across the order avoids changeover time, and a colour nobody else uses may carry its own minimum purchase.
• Flexible delivery windows. Factories price tighter when the schedule is free.
• Simplify the fastener schedule. Six different bolt sizes cost more in handling than two.
• Combine line items into one shipment. Consolidating spares, models and consumables spreads documentation and handling.
• Avoid changes after approval. Late drawing revisions are the most expensive kind of saving.

Frequently asked questions

Can you make a single prototype?

Yes, prototypes and samples are made, but they are priced to cover the setup described above. The prototype cost usually drops out of the unit price once the batch quantity is reached.

Can we mix models to reach the minimum quantity?

Sometimes, if the models share material, finish and production route. Send the full requirement and we will review it as one package rather than pricing each line separately.

Does quantity change the design itself?

It can. Higher volumes justify jigs and dedicated tooling that improve consistency, while small runs may favour bolted or simplified constructions. This is discussed during quotation, not decided afterwards.
