How long is a quote from a global supplier of plastic tool boxes valid?

Answer: Twenty days normally, seven when resin moves fast; 1 CNY per kg lifts a unit by 1.9 CNY.

Can MOQ fall below 500 pieces?

Answer: Yes, at a price: tooling lands in the unit rate and roughly doubles it, and the run waits for a press slot.

Who owns the mould once tooling is paid?

Answer: Whoever the contract says, though a mould paid in full usually stays with the buyer.

How do you test a claimed daily capacity?

Answer: Press nameplate, cavity count with cycle records, three months of shipments; 42 seconds on one cavity gives 1,885 pieces.

What happens if inspection fails?

Answer: A lot above AQL 2.5 on majors is reworked and re-inspected; minors may pass with a debit note.

1. How a Global Supplier of Plastic Tool Boxes Builds a Quote

One total price leaves nothing to negotiate over. A global supplier of plastic tool boxes should quote five lines, shell, hardware, foam, packing and tooling, and keep freight outside them.

Shell cost runs on shot weight: 1.9 kg at 9.6 CNY per kg of PP compound with a 1.04 loss factor is about 19.0 CNY. A 2.8 to 3.2 mm wall band shifts that by 60 to 90 g, so both belong in the quote.

Quote line	Basis	Typical share	Must state
Shell	shot weight × resin rate × 1.04	42 to 50%	grade, wall band, resin date
Hardware	latches, handle, hinge per set	20 to 26%	holding force, salt-spray hours
Foam	EVA or EPE, area × density	9 to 13%	density, die cost included
Packing	bag, corners, carton per set	6 to 9%	flute type, stack height
Tooling	one-off, per set	separate line	cavities, tonnage, ownership

Hardware is where offers blur: a latch rated at 180 N and one called standard feel alike on the desk, then part ways. Die-cast zinc wants 96 hours of neutral salt spray in writing.

2. MOQ Tiers and Tooling Amortisation

MOQ from a global supplier of plastic tool boxes follows tonnage and cavity count. A 520 × 380 × 240 mm box needs a 380-tonne press, one cavity and a 42-second cycle, about 1,885 pieces a day over 22 effective hours.

Tooling at 86,000 CNY per set spreads unevenly: 172 CNY a unit at 500 pieces, 43 CNY at 2,000, and 17.2 CNY at 5,000.

Tier	Tooling per unit	Material and conversion	Landed price
500	172 CNY	41 CNY	about 213 CNY
2,000	43 CNY	38 CNY	about 81 CNY
5,000	17.2 CNY	36 CNY	about 53 CNY

Place the first order at the 2,000 tier while locking the 5,000-tier formula, with a rebate if volume lands within twelve months. A colour change costs 40 minutes of press cleaning, so runs are sequenced by colour.

3. Lead Time in Four Milestones

Lead time is four dates, not one figure. A global supplier of plastic tool boxes needs 18 days to first article, 7 for approval, 25 for production and 3 for loading, 43 in total; a mould already in the rack needing only a colour change shows a sample in 6 days.

Loading sets freight cost: 420 pieces of the 520 mm size fill a 20-foot container, 980 a 40-foot high cube. Transit runs 21 days to Los Angeles, 32 to Hamburg and 24 to Jebel Ali, so the ocean leg needs its own line.

4. First-Article Checks That Decide Acceptance

Judging a global supplier of plastic tool boxes starts in the cavity: three readings each on length, width and height against plus or minus 1.5 mm, then wall thickness at six points, with anything under 2.6 mm returned. Calipers and a bore gauge, never a tape.

Latches should hold 180 N closed, hinge torque sit near 1.8 N·m for clean opening in the cold, and appearance match the signed sample at AQL 2.5 for majors and 4.0 for minors. Three sealed samples follow, one each for buyer, plant and shipment.

5. Payment Terms and Shipping Documents

Thirty per cent deposit with a 70% balance on the bill of lading copy is standard, the deposit covering resin and press time. A first order may split 30/40/30 against an inspection report. Letters of credit add 7 to 10 days of document checking.

Five papers travel with each shipment: packing list, invoice, bill of lading, certificate of origin and a compliance report, REACH and RoHS for Europe, a prop 65 statement for North America.

Conclusion

Procurement is a test of how much of a promise can become a number. Five quote lines, tooling spread per unit, four dated milestones and a 1.5 mm cavity tolerance turn a vague offer into something a contract can hold, and that is the standard for any global supplier of plastic tool boxes.
