How many units make a full load in custom plastic case wholesale?

Answer: On this 605 × 440 × 220 mm carton, a 40HQ takes 780 and a 20GP takes 320. Below 320 the order goes LCL at 5 to 8 percent more.

Does a 5,000-piece order cut the price much further?

Answer: Slightly. Tooling is waived past 3,000, so only resin, machine time, hardware and packing remain.

Is paying for tooling upfront cheaper than amortising it?

Answer: For one run, amortise and keep the cash. For repeats over two years, buy outright in custom plastic case wholesale, and write down ownership and storage.

Who draws the loading plan?

Answer: The plant draws it, the buyer signs it off. It needs a side view, a top view, the centre of gravity and the bracing method.

When does the payment term start?

Answer: On the bill of lading copy, not the day the doors close, so a rolled booking in peak season does not eat your credit period.

One 780-Case Container: Custom Plastic Case Wholesale in 31 Days

Quick answer: Most of the spread in custom plastic case wholesale quotes sits in batch size, tooling treatment and packing, not resin. One 780-case order shows it: three tiers, 320 pieces in a 20GP against 780 in a 40HQ, marks, mixed loading, and where 25 to 35 days goes.

FAQ

1. What the Enquiry for This 780-Case Order Left Out

The enquiry ran to three lines: 605 × 440 × 220 mm, black, five hundred pieces, best price. The size gave no wall thickness, the quantity no word on a full load, and black is a colour, not a masterbatch code. A custom plastic case wholesale quote is a list of assumptions laid open, so I sent back a five-line form. It came back at 780 pieces, one 40HQ, sixteen yuan cheaper a unit.

Enquiry field	First version	Completed version	Effect on the quote
Outer size	605 × 440 × 220 mm	Same, latches and feet included	Sets cavities and carton size
Wall thickness	Blank	3.2 mm side, 3.5 mm base	Weight rises from 3.6 to 4.1 kg
Quantity	500	780, full load	Price falls from 168 to 152 yuan

2. Tier Pricing at 500, 1,000 and 3,000 Pieces

The single-cavity tool costs 68,000 yuan and does not move, so the fewer the pieces, the heavier each one's share: 136 yuan a unit at five hundred, 68 at a thousand, nothing at three thousand. A custom plastic case wholesale quote sheet must state whether tooling is separate, amortised or waived.

Tier	Unit price	Tooling	Per unit	Lead time
500	168 yuan	68,000 yuan upfront	136 yuan	25 days
1,000	152 yuan	68,000 yuan upfront	68 yuan	28 days
3,000	139 yuan	Waived, ownership written in	0 yuan	35 days

The column people misread is lead time. Three thousand is slowest: two machine slots and a masterbatch delivery. Five hundred jumps the queue and pays the changeover alone.

Settle the batch before the price, or every figure you win is a figure on paper.

3. 320 Cases in a 20GP, 780 in a 40HQ

A loading plan is drawn for the crew standing in the box, not for the carrier.

A 40HQ measures 12.03 × 2.35 × 2.69 m inside; five across, nineteen deep, ninety-five a layer.
Eight layers make 760, and the metre at the door takes 20 more, so 780 fit at 74 percent utilisation.
A 20GP measures 5.90 × 2.35 × 2.39 m inside; seven layers of 315 plus five at the door makes 320.
Heavy cartons low, light high, centre of gravity under 1.05 m; past 1.2 m the load leans in a turn.
Side-to-side weight within 200 kg, front-to-rear 40 to 60, nothing pallet-high within a metre of the door.

In custom plastic case wholesale, eight of ten transit failures trace to the last two rows nobody braced.

4. Shipping Marks, Mixed Loading and Three Lines

Four lines are enough: consignee code, port of discharge, carton 1 of 780, gross weight 5.8 kg, volume 0.0725 m³. Characters no smaller than 50 mm, waterproof ink, 30 mm in from the edge.

Mixed loading keeps three lines: no mixing wall thicknesses, no mixing colour batches, no accessory cartons buried at the far end. One model can split by colour, three shades a block.

5. The 25 to 35 Day Window and Three Inspection Gates

This order was promised at twenty-six days and ran to thirty-one; the extra five sat waiting on masterbatch.

Stage	Days	Starts when	Typical slippage
Material	5	Deposit clears	Masterbatch late
Moulding	12	Material on floor	Slot taken by a rush order
Assembly	4	First parts off the tool	Valve leaks, rework

Three gates, not one. The first-off check runs the day the tool starts: five thickness points, a lid closure test, a handle pull. Mid-run comes at forty percent with fifty units pulled. Final check happens before the doors close. Payment runs thirty percent deposit, seventy on the bill of lading copy; sixty days adds 1.6 percent.

Conclusion

What sets the price in custom plastic case wholesale is not resin but three documents: an enquiry sheet naming every assumption, a tier table tying tooling to batch size, and a loading plan drawn to the layer. Keep them on file and the next custom plastic case wholesale order starts from a known place.
