Why do Ordnance Packing Box quotes vary so much between suppliers?

Answer: Rarely labour. A 4.0 mm and a 5.0 mm wall differ by 2.2 kg of resin, a 20 mm to 30 mm insert adds over RMB 20, and tooling over 300 instead of 800 units adds RMB 100.

Can the MOQ go below 200 units?

Answer: Yes, at a higher price and a later slot; a colour or cavity change is quoted at the 400-unit tier.

Is the sampling fee deductible?

Answer: Mock-up fees are not refunded; mould cost is credited once cumulative volume reaches 800 units, if the contract names the orders.

What happens if inspection fails?

Answer: Defects are graded: a critical failure means rework or rejection of the batch, a general failure allows sorting or a price adjustment.

Are 30/60/10 terms reasonable?

Answer: For a first order. On a repeat, 20/70/10 is fairer: the tooling is paid off and the acceptance gate still holds.

Ordnance Packing Box Procurement: Quotes, MOQ and Lead Times

Quick answer: An Ordnance Packing Box price is five blocks: material, tooling, insert, packaging and freight. MOQ follows how far the tooling is spread; lead time starts at drawing freeze.

FAQ

1. What an Ordnance Packing Box Quote Is Made Of

Quotes usually arrive as one total. Split an Ordnance Packing Box into five blocks and the differences become checkable. An 800×520×340 mm rotomolded case at 800 units costs RMB 412: material 138, tooling 60, insert 74, carton and pallet 26, freight 18.

Cost block	Priced on	Check this
Material	Net weight times resin, 8% regrind	Wall thickness and weight
Tooling	One-off over committed volume	Basis and mould ownership
Insert	Sheet, die, labour	In unit price or not
Packaging	Carton, pallet, film	Pallet quoted or not
Freight	Volumetric against actual	Which basis applies

Material is where discounts do damage. The shell is 9.6 kg at a 4.0 mm wall; at 5.0 mm it reaches 11.8 kg and costs RMB 25 more. A supplier who accepts the thicker wall without repricing recovers it through regrind ratio.

Tooling is one-off, so the argument is the amortisation basis. The same RMB 48,000 mould costs RMB 160 per unit over 300 pieces and RMB 60 over 800.

2. MOQ and How Tooling Cost Is Amortised

MOQ is not a capacity limit but a cost-sharing result: mould change, material change and purging take fixed time a short run cannot absorb.

Tier	Quantity	Effect on unit price
Trial, existing mould	200 units	Tooling over 800, rebate on reorder
Colour change	400 units	40 minutes purging, plus RMB 12
New mould	800 units	Full amortisation, lowest price

Colour changes set a higher floor than buyers expect. Rotomolding needs 40 minutes of purging and the first three shots are transition material; injection needs over 20 shots to stabilise. Below 400 units plants add a surcharge or blend those shots into the order, the usual origin of colour drift.

3. Sampling and Mass Production Lead Times

Lead time starts at drawing freeze. A printed mock-up ships in 8 days and proves outline and insert layout only, not wall thickness, latch force or sealing. A moulded sample waits for the tool: 26 days, then 3 days of T1 trials, and those 26 days belong in the plan when sealing has to be proven.

Mass production runs 32 days: material 5, rotomolding 8, trimming and assembly 6, inserts 6, packing 2, inspection and loading 5. Inserts run in parallel if the die is released after T1, saving about 7 days.

4. Inspection Gates: First Article, In-Process, Pre-Shipment

Three gates cover an order, and skipping one pushes the problem past loading: the first article covers dimensions, in-process covers consistency, pre-shipment covers deliverability.

Ordnance Packing Box: three olive-green cases stacked on a steel shelf, latches in a row, an open case with egg-crate foam on a pallet

The first article takes 3 units and 11 dimensions: cavity and outer length, width and height, lid step height, wall thickness at three points, latch spacing.

In-process inspection pulls 2 units per 50 for wall drift and latch force, which should sit between 180 and 220 N; below that the seat has deformed or the gasket is too thick. Pre-shipment uses AQL 2.5 and 0.65, or 13 units out of 800, with sealing, latches and hinges critical.

5. Payment Milestones and Risk Allocation

Payment ratios allocate risk. An Ordnance Packing Box order runs long, tooling first, so each milestone sits on an inspection gate: 30% against signed drawings, 60% against a passed pre-shipment check and a bill of lading copy, 10% retention 30 days after acceptance.

Tooling ownership transfers at 60% paid, and the plant may not cut it for a third party. Price review reopens only beyond an 8% resin move. Delay liability is 0.3% a week, capped at 5%, deductible from retention.

Conclusion

Negotiation over an Ordnance Packing Box comes down to three sheets: a quote split into five blocks, a tooling clause naming the amortisation quantity, and a payment table aligned with inspection gates. When they disagree, a low price is repaid in lead time. Normalise wall thickness, net weight and insert thickness first; the remaining gap is the only real difference on an Ordnance Packing Box.
