What is the minimum order from a private label plastic case manufacturer?

Answer: Usually 300 to 500 pieces. Three hundred suits a trial run with a colour change; 500 and above allows dedicated packaging print and about 6 percent off.

How detailed should the licence be?

Answer: Cover registration number, goods class, term and territory. A letter naming only the brand is often rejected at export declaration.

Can the factory handle cartons and manuals end to end?

Answer: Yes, with artwork signed by the brand and barcode grade owned by the factory. Proofing then follows their calendar.

How long should golden samples be kept?

Answer: Eighteen months. Store them away from light; polypropylene yellows within three months under strong light.

Private label plastic case manufacturer: a six-point checklist

Quick answer: Vetting a private label plastic case manufacturer is not a price conversation. It is six items with an owner and a date: licence scope, carton and manual printing, barcode labels, packaging cost share, MOQ with mould ownership, and golden-sample sign-off.

FAQ

1. Start with trademark licence scope

Before anything else, a private label plastic case manufacturer needs the trademark licence on file. The letter states the registration number, the goods class and the term.

Scope is where programmes stall. Too broad, and the factory hesitates; tied to one model, every colour change needs another letter and two weeks.

Filing cannot be skipped: the factory keeps a scan, and export documents or marketplace review may ask for it.

Private label element	Owner	Lead time
Licence and scope	Brand issues, factory files	5 days
Carton and manual artwork	Brand designs, factory proofs	7 days
Barcode and labels	Factory registers, brand confirms	3 days
Golden sample	Both sides sign on site	2 days
Shipment and documents	Factory	10 days

2. Carton, manual and barcode printing duties

For a private label plastic case manufacturer, cartons, manuals and barcodes are three print jobs with three owners, and lumping them together means each waits.

Private label plastic case manufacturer: grey case open on a bench, foam holding a grey electronic module, coiled cable, two compartment trays.

Cartons usually take five-ply corrugated board at 1300 kPa burst strength minimum. The shipping mark sits 50 mm above the bottom edge, and handling symbols must not cover it. Size the carton from the case plus 15 mm of cushioning, not from last year's drawing.

The manual is the item that gets reprinted. Four colours plus one spot, colour difference within Delta E 2.0, and fold order signed on the proof, or English pages turn up behind Chinese at mass production.

Barcodes are EAN-13 at 37.29 by 25.93 mm, magnification 0.8 to 2.0, with a 3.63 mm quiet zone on each side. Trim it and the scanner misses three reads in ten.

3. Packaging cost share has to be priced line by line

Packaging lands between 8 and 12 percent of unit cost, and it is the first thing a private label plastic case manufacturer folds into a single price so nobody sees where the money went. Breaking it out is simple: on a 620 by 420 by 260 mm case, carton 6.5, manual 0.8, labels 0.35, inserts 2.2, tape and straps 0.6, for 10.45 against a 96 case, or 9.8 percent. Itemising pays three ways: inflation lands on a known line, a packaging supplier can be swapped alone, and customs declarations match the invoice. A single total usually means cheapest stock carton and a two-colour manual. Both sit in plain sight on the shelf, and the savings return as rejects. Some quotes hide packaging as free, which also means no acceptance standard.

4. MOQ, mould ownership and sampling fees

A private label plastic case manufacturer usually sets a minimum of 300 to 500 pieces, below which setup and machine time cannot be absorbed.

Private label plastic case manufacturer: grey case open on wood, empty black foam, side and front handles, three compartment trays in front.

A mould at 80,000 can be owned three ways: the brand buys it outright and stores it on site, with a disposal clause; the factory holds it and grants two years of exclusivity with amortisation; or the factory holds a reusable tool at the lowest unit price, with the same shell free to appear in another catalogue.

MOQ tier	Mould ownership	Unit price effect
300 pcs	Brand buys outright	About 12 percent amortisation
500 pcs	Factory holds, brand exclusive 2 years	About 7 percent amortisation
1000 pcs	Factory holds, reusable	About 4 percent amortisation

Sampling is billed separately, typically 3,000 to 5,000, refunded above 500 pieces. State whether the refund keys off quantity or payment value.

5. Five actions for first-article approval

A golden sample is not a photo in a folder. It is a physical part someone can compare against and blame later.

Pull three first articles: brand, factory, and one travelling with the shipment
Label each with model, colour code, date and both signatures
Retain for 18 months, a full warranty cycle
Compare seven items: colour, print position, barcode grade, latch force, gasket compression, insert fit, torque
Re-sample after any change, including masterbatch or packaging supplier

The travelling sample earns its keep: nobody opens a carton to judge.

6. Lead time, factory audit and payment terms

A private label plastic case manufacturer typically quotes 45 days: fifteen for licence and sampling, twenty for production, ten for shipment. Squeeze one block and another absorbs the delay.

Audit the plant once. Look at injection tonnage and mould storage: too little tonnage starves a large shell, loose moulds mean re-alignment next run.

Terms are commonly 30 percent deposit and 70 percent against a bill of lading copy. Push the deposit below 20 percent and the order slides down the schedule.

Add one clause: remind the brand 60 days before the licence expires, and stop production with packaging sealed if not renewed. That clause saves a container stuck at the border.

Conclusion

A checklist tells you more about a private label plastic case manufacturer than a price list: licence clarity, print ownership, packaging in five lines, MOQ against mould ownership, who holds samples, lead time matching payment terms. Six answers, six owners, six dates, and quotes become comparable across private label plastic case manufacturer candidates.
