Three Transit Case quotes differ by 40%. Which do I trust?

Answer: The itemised one; if the gap sits in foam density, latch brand or tooling, the cheapest quote cut a specification.

Can MOQ be pushed to 100 units?

Answer: Yes, but expect a smaller machine or a welded build, 20% to 35% higher price, and less strength.

Buy the tool outright or amortise it?

Answer: Amortise under three years, buy beyond five. A buyout must name storage, maintenance and tool transfer cost.

How do I make a delivery date stick?

Answer: Five milestones with deliverables and liquidated damages, 0.3% a day capped at 5% of contract value.

What makes a breakage clause work?

Answer: A stated basis, a stated period and a replacement deadline. Count per delivery batch, settle quarterly, replace within 30 days.

Transit Case Procurement: Quotes, MOQ and Lead Times

Quick answer: Three things decide what a Transit Case really costs: whether the quote is itemised, how tooling is amortised against order quantity, and whether lead time is broken into milestones. Fix all three in the contract and price and delivery become controllable.

FAQ

1. How to Break Down a Transit Case Quotation

Same drawing, three quotes, a 40% spread: the gap rarely sits in the shell. It sits in foam density, latch brand and how tooling is spread. Ask for an itemised quote first.

Cost item	Share	Basis
Shell	58%	weight, resin, machine rate
Foam insert	19%	density and cutting time
Latches, hinges	11%	per set
Packing, pallet	5%	per unit
Tooling	7%	one-off or per unit

Foam from 25 to 45 kg/m³ adds about 18 CNY a unit; a glass-filled nylon latch saves 6 CNY and halves life from 8,000 to 3,000 cycles.

Ask who owns the tool and what a transfer costs; unclear ownership traps a buyer at the next change.

2. MOQ and Tooling Amortisation: 500 vs 3,000

A single-cavity Transit Case tool at 48,000 CNY costs 96 a unit over 500 pieces, 16 over 3,000: an 80 CNY gap no haggling closes.

Transit Case: large grey case open on a long warehouse bench, cut foam in the lid, black power supplies beside, cartons on shelves

MOQ follows cavity count and changeover cost. 300 pieces is the usual floor; below it, plants quote a smaller machine or a welded build, at a higher price and less strength. For a hundred-unit trial, a stock size beats a new tool.

Amortisation comes three ways: all on the first order, spread to a 3,000-piece cap, or bought outright at about 1.2 times tool cost.

Write the cap down: no tooling charge past 3,000 pieces, colour changes billed at 3,000 CNY each.

3. Lead-Time Milestones: From Tool to Shipment

A single delivery number is the easiest thing to miss; milestones with deliverables give you something to hold.

Milestone	Working days	Deliverable	Trigger
Tooling	22	acceptance sheet	30% advance
First article	6	report, sample	none
Pilot batch	10	50 units, records	none
Volume	24	lot, shipping report	60% on B/L

The critical path is tooling and first article; volume compresses, tooling does not. To cut ten days, drop the slides or prove assembly on an aluminium prototype and run the first article with the pilot.

Peak season has its own arithmetic: 30 days before Spring Festival, the same tool takes 15 days longer. Write working days, not calendar days.

4. Sample and First-Article Sign-Off

A sample is not a colour check. Appearance, then assembly, then verification: colour and print position, foam pockets and latch feel, then drop and stack before sign-off.

Transit Case: translucent grey case open on a lab bench, foam cut for white modules, a matching box beside it, glassware behind

Each step can veto the rest. Fail appearance and everything restarts; fail assembly and only the foam drawing changes; fail verification and you must separate structure from process. Merge them and you learn after volume that a latch sits 3 mm off.

Samples run about 1,200 CNY each, two refunded at 500 pieces. The sign-off sheet carries three hard lines: colour code, foam density, latch model.

5. Payment, Inspection and Replenishment Terms

Payment belongs on milestones, not on the calendar.

Term	Suggested	Note
Advance	30%	tooling, first resin
Shipment	60%	3 days from B/L copy
Balance	10%	15 days after acceptance
Breakage	0.8%	supplier replaces above
Replenishment	50 units	12% premium cap
Price review	resin ±5%	quarterly

Inspection runs AQL 2.5 on 50 units, zero tolerance on fatal defects. A failed inspection holds the balance until rework passes; put that in the payment clause.

Replenishment is the clause everyone forgets. Latches and lids fail first, and reorders run to dozens. Fix a 50-unit minimum, 12% premium cap and 20 days delivery, or a 20-unit reorder gets quoted at the new MOQ.

Conclusion

Buying a Transit Case comes down to three sheets: the itemised quote shows what you compare, the amortisation sheet where unit cost lands, the milestone sheet who to call when it slips.

Payment and replenishment belong to lifetime cost: once breakage and price review are written down, year-two reorders stop being a negotiation. That is how Transit Case procurement stops being a one-off haggle.
