What unit price is reasonable from a bulk plastic storage box supplier?

Answer: Split first, then index. Body at 62 to 70 percent and hardware under 10 percent is normal; quotes within 8 percent differ in basis.

Can an order under 2,000 be placed?

Answer: Yes, about 10 percent more per box, 26 days or longer, existing colours only.

Is tooling refundable?

Answer: Usually the buyer pays and owns it, with a partial refund past an agreed repeat volume.

What extra acceptance applies to a cold store?

Answer: A 1.0 m drop on six faces after four hours at -25°C with no cracking, plus 24 hours at three high.

Can lead time be cut to 24 days?

Answer: Only with an existing tool plus stock hardware. The 16 days of tool making are physical.

What does a factory visit check?

Answer: Press tonnage, tool register, three months of shipping records. One 780 tonne press tops out near 2,117 boxes a day; two cannot make 300,000 a month.

Quick answer: A bulk plastic storage box supplier should split the price into body, hardware, packing and tooling, price it across 2,000, 5,000 and 10,000 unit tiers, and accept cold-store stacking tests.

FAQ

1. What a Bulk Plastic Storage Box Supplier Needs in the RFQ

An RFQ leaves with a drawing and a volume. One lump sum back has nothing to negotiate.

A bulk plastic storage box supplier should answer in four lines: body, hardware, packing, tooling, each with its own basis.

The body is priced by weight: 4.2 kg times the compound rate times 1.04. Every 1 yuan per kg on resin moves a box by 4.4 yuan, so pin the grade and date.

Line	Basis	Share	Pin down
Body	weight × rate × 1.04	62 to 70%	PP grade, date
Hardware	latches, hinge, rivets	7 to 9%	alloy, plating
Packing	bag, pads, pallet	6 to 8%	units per pallet
Tooling	one-off	separate	cavities, ownership

2. Quantity Tiers and Who Owns the Tooling

Tiers follow tonnage: an 800 mm box needs a 780 tonne press, two cavities, a 68 second cycle, so 2,117 boxes a day.

Bulk plastic storage box supplier: one grey hard box on a pale grey background, two front latches closed, recessed lid handle, four vertical ribs

2,000, 5,000 and 10,000 is the usual ladder. The 2,000 tier costs most: a colour change eats 35 minutes and first-run scrap nears 4 percent.

Tier	Index	Tooling	Lead time	Shipping
2,000	100	billed in full	26 days	640 per 40HQ
5,000	94	half amortised	29 days	two lots
10,000	88	absorbed, 4.6 yuan each	32 days	four lots

A 46,000 yuan tool over 10,000 boxes is 4.6 yuan each. Two clauses to write down: ownership stays with the buyer and repeats pay nothing; three tool changes are free. Both beat 1.5 yuan off unit price.

3. Lead Time from Steel to Loading

32 days are 16 of tool making, 3 of trials, 13 of production. What slips is the front end: masterbatch, latch samples, printed cartons. Build the schedule backwards: loading day minus 2 for inspection, minus 13 for production, minus 3 for trials, the rest belonging to the tool. Write the start point as sample sign-back, or two weeks of courier samples sit inside your lead time. Hold one day for first-article approval, since nothing moves until it is signed. Split the load: 2,500 on day 32, the rest every eight days.

Check capacity at the press: which machine ran the last 10,000, and can the shot log be pulled?

A bulk plastic storage box supplier should attach the schedule to the contract, with damages at three per mille a day.

4. Stacking, Packing and Warehouse Turnover

The dock sits at -25°C, the sort area at 18°C, a 43 degree swing. Polypropylene goes brittle, so drop height and stacking are reset.

Bulk plastic storage box supplier: open grey box on a white floor, lid ribs and seal visible, coiled black cable and clear trays inside

A 2.6 mm copolymer wall holds five high at room temperature, three high after four hours at -25°C, bottom layer on a pallet.

Condition	Stack	Bottom load	Note
Ambient store	5 high	105 kg	21 kg per box
Cold store, -25°C	3 high	63 kg	after four hours
Dock, temporary	2 high	42 kg	six hours maximum

Turnover rewrites packing. Two in and two out a day wants a 1,200 by 1,000 mm pallet, eight boxes a layer, three wrap passes; monthly movement needs cartons.

5. Payment Terms, Resin Index and Price Validity

Thirty percent deposit, seventy on a bill of lading copy, is the standard ask from a bulk plastic storage box supplier; below 20 percent it returns in the resin rate.

Sixty-day terms track volume: sensible on 10,000 boxes, costly on 2,000.

The resin clause cuts both ways: fixed grade, a 6 percent band, movement up or down.

Validity of 21 days is realistic; past that, one resin move rebuilds it.

6. Six Traps in a Bulk Quote

A 1.12 loss factor unexplained is an 8 percent rise wearing a technical label.
Tooling amortised into the unit price is charged again on repeats.
Standard packing excludes pallet and wrap, so 1.6 yuan per box appears later.
Lead time counted from deposit hides two weeks of samples in the 32 days.
Equivalent alloy turns out to be zinc-plated cold-rolled steel failing 48 hours of salt spray at grade 9.
Acceptance on appearance alone cannot reject a batch 0.3 mm out of cavity tolerance.

Conclusion

Buying in bulk comes down to three sheets: the quote, the quantity ladder, the stacking and schedule sheet. With those on the table, price, tooling and slot settle early. Add a cold-store clause and most risk closes. The test of a bulk plastic storage box supplier is whether it hands them over unasked.
