Quick answer: Most of the spread in small hard plastic case wholesale quotes comes from tooling ownership, not unit price. Fix the mould route first, agree amortisation across three MOQ tiers, then protect delivery with mixed loading and three inspection gates.

1. MOQ Tiers Set by Tooling Ownership
The first question in small hard plastic case wholesale is where the model comes from, not the unit price. For a 460 × 350 × 200 mm body, stock, modified and new-mould routes differ sixfold on MOQ and by RMB 40,000.
| Route | MOQ (pieces) | Tooling (RMB) | Sample lead time | Tooling title |
|---|---|---|---|---|
| Stock mould, colour change | 500 | 0 | 7 days | Factory |
| Stock mould, structure change | 1200 | 4800 | 12 days | Factory, buyer holds exclusivity |
| New mould | 3000 | 38000 | 28 days | Transfers to buyer on payment |
How tooling is amortised matters more than its amount. Charged against the first order, it adds over RMB 10 per unit; spread across three years, it needs a floor volume.
On the new-mould route the title clause needs its own paragraph. Tooling becomes buyer property once paid in full, held in factory custody for three years. A quote silent on ownership defaults to the factory.
2. Mixed Loading: How Many Sizes Fit One Cabinet
Mixed loading only works when each size clears its own MOQ. Three models at 500 pieces still go in as three orders of 500; pressed into one 1,500-piece order, the shop pays for three changeovers.
A 40HQ cabinet is planned as 68 m³ of usable space in small hard plastic case wholesale work. The three sizes below come to 41.3 m³ net, and pallet gaps plus carton seams add about 10%. That is 45 m³ occupied and 23 m³ left for other models. Whatever sits at the door is unloaded last, so that slot goes to the end customer. Break no pallets and the gap between bodies runs 10 to 12 mm. Quotes built on net volume lose that quietly.
| Size (mm) | Volume per piece (m³) | Quantity | Space taken (m³) |
|---|---|---|---|
| 460 × 350 × 200 | 0.0322 | 900 | 29.0 |
| 380 × 280 × 165 | 0.0176 | 550 | 9.7 |
| 300 × 220 × 130 | 0.0086 | 300 | 2.6 |
Odd cartons are where mixed loading fails. A part pallet per size gets shoved into the doorway and the last customer opens the wrong model first.
3. Where Colour Boxes, Barcodes and Labels Cost Money
Print packaging is a few points of a small hard plastic case wholesale order. A 350 g white-card box costs RMB 1.20, a five-ply carton of six RMB 3.80, a barcode label RMB 0.05, for RMB 1.88 per unit.
| Packing item | Unit cost | Per case |
|---|---|---|
| White-card colour box | RMB 1.20 | RMB 1.20 |
| Five-ply outer carton | RMB 3.80 | RMB 0.63 |
| Barcode label | RMB 0.05 | RMB 0.05 |
| Total | — | RMB 1.88 |
Barcodes follow the retailer's symbology, not the printer's habit. Film output runs at 10 mil, and a first-read rate below 98% means a reprint.
One artwork change is one press stop, with seven days attached.
4. Sampling Ratios: Three Gates and an 80-Piece Sample
Sampling ratios are calculated, not improvised. Below 3,000 pieces draw 80; from 3,000 to 10,000 draw 125; above that follow inspection level II with AQL 2.5 for major and 4.0 for minor defects.
The three gates do different jobs:
- First-off: three pieces measured in full, three points each on wall, cavity and latch engagement
- Patrol: five pieces every two hours, checked for flash, sink marks and colour drift
- Pre-shipment: 80 pieces drawn, ten of them dropped 1.2 m onto six faces
The accept rule belongs in the purchase order. The same lot passes at 2.5 on major defects and fails at 1.5.
5. Payment Terms, Tooling Title and Four Quote Traps
Payment terms are part of the price. Thirty per cent deposit with seventy per cent against the bill of lading copy is standard; 60 days costs 1.5 to 2 points, which returns through the unit price.
Four traps in a small hard plastic case wholesale quote are worth clearing before sampling:
- Tax included, freight excluded, with freight priced per cubic metre
- Unit price fixed for three months, adjustable once resin moves 5%
- Tooling described as free, with the title left at the factory
- Free sampling, with the cost recovered inside the first 3,000 pieces
Put all four into a contract annex; it holds better than ten chat confirmations.
Conclusion
In small hard plastic case wholesale costing, tooling, MOQ and packaging move the total more than a few cents on the unit price. Write ownership, mix ratio, artwork revision and the accept rule into the contract, then compare prices: small hard plastic case wholesale sourcing starts from the right question.
