Quick answer: Three quotes for the same plastic tool box wholesale order rarely differ by more than a few dollars a unit, and the real gap sits in shot weight, tooling ownership, the start date of lead time and payment terms, so split the price into material, moulding, tooling spread, packing and freight before comparing.

1. Seven Fields That Belong on the RFQ
Three suppliers quote the same 18-inch box at 26, 28 and 31 dollars. The 26 dollar one is not the same box: 0.78 kg of material against the 1.05 kg sample.
What separates them is the boundary behind each number: the 26 dollar quote left out tooling, cartons and inspection, while the 31 dollar one carried all four.
| Field | Common wording | What to write |
|---|---|---|
| MOQ | to be discussed | three tiers at 200, 500 and 1,000 units, priced separately |
| Material | virgin PP | grade and melt index, regrind cap written into the contract |
| Shot weight | about 1 kg | 1.05 ± 0.03 kg per unit, lid and handle included |
| Tooling | extra | amount, cavities, ownership and amortisation as four lines |
| Lead time | 25 days | 25 working days from sample sign-off |
| Packing | carton | four per carton, five-ply, marks per attachment |
| Price term | ex works | FOB Shenzhen, VAT included |
Shot weight and tooling are where the vagueness lives: one sets material cost, the other fixed cost, and a soft figure in either corrupts every comparison downstream.
2. Shot Weight and Wall: Where Two Prices Part
Material is 55 to 65 percent of a plastic tool box wholesale unit price. An 18-inch box at 1.05 kg takes 9.5 dollars of PP, 6 to 8 for moulding, energy and depreciation, 1.8 for the carton, 0.6 for tooling over 30,000 units. A 26 dollar quote leaves 7 dollars for material: 0.78 kg, 26 percent under the sample, wall down from 2.6 mm to 2.0 mm.
Weigh five units on receipt, lid and handle on. More than 3 percent under nominal and the batch is reweighed, because a lid alone is 60 to 80 g.
Check wall at nine points with an ultrasonic gauge and refuse anything below 85 percent of nominal; without one, measure the rim flange at about 1.2 times the wall.
Regrind shows as grey, and a falling-dart test splits first opposite the gate.
3. MOQ and Tooling: Who Pays, Who Owns It
Tooling runs 8,000 to 25,000 dollars depending on cavities and lid slides.
A single-cavity mould suits 200 to 500 units at 8,000 to 12,000 but costs more per part; a 1x2 at 18,000 to 25,000 doubles output and needs 1,000 units to amortise. Charge it three ways: buyout, per-unit amortisation, or supplier-funded with 8 to 12 percent on price.
| MOQ | Tooling arrangement | Cost per unit | Fits |
|---|---|---|---|
| 200 | buyout at 9,000 | 45, one-off | trial, samples |
| 500 | buyout at 9,000 | 18, one-off | regional test order |
| 1,000 | buyout, spread over 30,000 | 0.3 | routine replenishment |
| 3,000 | supplier-funded, price uplift | buried in price | long-term supply |
Ownership belongs in the contract: on a buyout the mould is yours, stored at the supplier and removable, while amortised tooling needs a clause on who owns it after 30,000 units.
Life is 300,000 shots, 200,000 with glass-filled compound; past that, flash grows from 0.05 mm to 0.3 mm.
4. Lead Time Starts at the Signed Sample
The 25 days on a plastic tool box wholesale order run from sample sign-off, not from the purchase order itself. Sample 5 to 7 days, material 3 to 5, moulding 7 to 10, packing 3, inspection 1 to 2, booking 5 to 7. Any slip pushes the rest, and moulding queues run 7 to 12 days from August to November; new tooling adds 25 to 35, and a custom colour inserts a 2 to 4 day match. Pre-printed cartons need a die and plates, 5 to 7 days, which can run alongside moulding but must be locked before printing starts.
| Stage | Normal | Compressible | Cost of compressing |
|---|---|---|---|
| Sample | 5–7 days | 5 | colour and structure risk sits with you |
| Material | 3–5 days | 2 | common grades only |
| Moulding | 7–10 days | 5 | 8–15% rush charge |
| Packing | 3 days | 2 | pre-printed cartons needed |
| Inspection | 1–2 days | 1 | smaller AQL sample |
| Booking | 5–7 days | 3 | faster vessel or air, freight doubles |
Only two stages compress: moulding, by reserving press time, and booking, by naming a sailing rather than waiting for a forwarder. The sample week does not compress without rework.
A deadline without a penalty is a wish: 0.3 percent of contract value a day, capped at 5 percent.
5. Payment Terms Are Part of the Price
Thirty days is not free; it sits in the unit price at 1.5 to 2 percent a month, and a first order granted 60 days usually pays for it in shot weight.
On a million dollar order, 60 days costs 30,000 to 40,000, about a dollar a box over 30,000 units. A 3 to 5 percent gap between cash and credit pricing is normal.
Payment usually runs on six nodes:
- 30 percent deposit within three working days of signing
- 30 percent after sample approval
- 40 percent against the bill of lading copy
- 30 days for established accounts, against financials or a guarantee
- 60-day letter of credit, documents at about 0.15 percent, buyer's account
- production suspended if the balance runs more than 15 days late
6. Six Ways a Quote Looks Cheap
On a plastic tool box wholesale sheet, cheap is usually a missing line.
- Body quoted without the lid, which appears as a 2 dollar extra at delivery
- Bare box quoted without carton, divider or mark printing, 1.5 to 2.5 dollars together
- Tooling split into a moulding fee and a trial fee, charged twice
- Shot weight quoted without the handle, 60 to 80 g light
- Lead time in working days rather than calendar days, 7 to 9 days longer in practice
- A price-adjustment clause that only moves up, triggered above 5 percent, with no mechanism to come down
The last one hurts most: PP from 8,000 to 11,000 a tonne adds 3 dollars to a 1 kg box, turning 26 into 29, and with no downward clause it never returns.
Write it both ways, against the monthly spot average, reviewed quarterly.
Conclusion
One sheet settles a plastic tool box wholesale comparison: shot weight, material grade, tooling ownership, lead time start, payment terms, packing and the adjustment clause, all seven before the price. The gap between 26 and 31 was never five dollars.
