Quick answer: Close the specification before you ask for a price. Compartment count, handle style and latch material all change the mould, so fix dimensions, load rating and latch type in the RFQ first, then split tooling, MOQ and delivery into separate lines. That usually pulls the spread between quotes from about 30 percent to under 8 percent.

1. Three Lists to Fix Before You Buy a Tool Carrier

Two tool carriers can share an outer footprint yet differ in compartment count, handle and latch. An RFQ that only says the case must hold a 40-piece socket set gets three stock designs back.

Issue three lists instead: specification for outer size, internal depth and load rating; acceptance for colour, flash, latch force and drop height; commercial for quantities, packing and payment.

Internal depth is the field most often omitted. A 420×320×120 mm case may be only 95 mm deep inside, and a 2.5 mm divider wall instead of 3.5 mm decides whether one more row of tools fits.

ListRequired fieldsUsually omitted
Specification420×320×120 mm outer, 95 mm internal depth, 12 compartmentsInternal depth and divider wall
AcceptanceΔE ≤ 1.5, 30–50 N latch force, 1.2 m dropDrop orientation and cycles
Commercial300 pcs pilot, 2000 pcs production, East China warehousePilot and production split

300 samples plus 2000 units prices 12 percent above one 2300-piece order.

2. Breaking a Quotation into a Real Unit Price

Most quotes arrive blended; ask for bare shell, assembly, packing and tooling separately.

Tool Carrier: one pale blue closed case, curved ribs at every corner, folding handle flush on the front, a latch on each side.
Tool Carrier: one pale blue closed case, curved ribs at every corner, folding handle flush on the front, a latch on each side.

On a 380-tonne press with two cavities at a 45-second cycle, the case takes roughly 480 g of polypropylene. Bare shell to assembled part adds CNY 6 to 9 for dividers, latches and handle. A quote under CNY 3 for assembly usually means the dividers are moulded in one piece, freezing the compartment size.

Align the basis: 13 percent VAT included, delivered to warehouse, one PE bag and a five-ply carton per case.

Weight tells the same story: two cases of identical outer size that differ by 40 g carry about 0.3 mm of wall thickness.

3. MOQ, Tooling Amortisation and Split Deliveries

MOQ is a tooling question in disguise. A new mould quotes at CNY 42,000: over 500 pieces that is CNY 84 each, over 2000 pieces CNY 21 — a CNY 63 swing on one mould. A split delivery adds a second material pull and mould change, typically 3 to 5 percent.

500 pcsCNY 84CNY 46CNY 130
1200 pcsCNY 35CNY 43CNY 78
2400 pcsCNY 17.5CNY 41CNY 58.5

A first order of 800 to 1200 pieces absorbs most tooling; above 20,000 units a year, spread it over three shipments.

4. Reading Lead Times and Press Schedules

A lead time is a chain: 5 to 7 days of material preparation, 3 of moulding, 2 of assembly, 2 of inspection and packing, 3 to 5 of transport.

Tool Carrier: five grey cases stacked, the second open to bare compartments, latches aligned down one side.

Press tonnage and cavity count expose a real date. A 380-tonne machine with two cavities yields about 900 cases a day, so 30,000 a month on one such machine means orders are squeezed in. September to November is export peak; lock volume before mid-August.

5. Inspection and Payment Terms in the Contract

Inspection terms must be executable: AQL 2.5, colour within ΔE 1.5, latch force 30 to 50 N, no cracking after a 1.2 m drop, no red rust after 48 hours of salt spray.

Tie payment to the report: 30 percent deposit, 60 percent against the bill of lading copy, 10 percent after acceptance.

Batch colour deviation is the supplier's cost; crush damage turns on whether packing followed the five-ply spec.

Conclusion

Buying a tool carrier is mostly a sequencing problem. Close the three lists, force the quotation open, then price tooling, MOQ and delivery separately — most of the 30 percent spread disappears on its own. A well-built RFQ decides the real cost of a tool carrier more than ten rounds of haggling.
