Who actually makes boxes and cases in China — and what can be verified about them.
BoxFactory indexes Chinese box, case and container manufacturers by category, region and evidence grade. Each published profile lists its sources and states plainly what we could not confirm. Company names are used to identify the businesses, not to imply any partnership.
How to use this directory
Start from the category, not the company name
Case manufacturing is localised by process. Pick the category that matches your shell (ABS/PP protective, aluminium, blow-moulded tool case, rotomoulded, turnover crate) and you will be looking at factories that actually run that equipment.
Read the evidence grade before the marketing copy
Grade A means the company’s own site or a registry/encyclopedia record confirms both identity and products. Grade B means we only found a B2B storefront. Grade C means the name appears in promotional content. Nothing on this site is a recommendation.
Ask the three questions that separate real factories from traders
Which process do you own (injection, blow, rotomould, aluminium profile assembly)? Can we see the mould list? Who issues the gasket, latch and foam — in house or bought in? The answers change lead time and cost more than price does.

Provinces are assigned from the registered address in the source listing; a factory’s production site and its registered address are not always the same place.
Buyer guides
PP, ABS, HDPE or aluminium: choosing case material before you choose a supplier
Material decides which factories can even quote you. A short decision table with the trade-offs that actually cost money.
How to vet a case manufacturer in China before you send a deposit
Ten checks that separate a factory that owns its tooling from a storefront reselling someone else’s catalogue — and what each answer means.
IP ratings on protective cases: what the numbers mean and what a claim needs
IEC 60529 dust and water codes, why "waterproof" on a listing is not a rating, and the design details that decide whether a case keeps water out.
OEM case programmes: tooling, lead times and what changes the schedule
The realistic sequence from a payload drawing to a shipped lot, and the three decisions that set your calendar.
Designing the foam liner: the cheapest place to protect an expensive instrument
Material, density, layering and drawing handoff — the liner decisions that decide whether the payload arrives.
EXW and FOB for case shipments: what each term makes you responsible for
Where the risk transfers, who books what, and the paperwork that gets containers held.
What this site is not
Independence and limits
- Not a marketplace: we do not take commission, hold payment or arrange inspection.
- Not an endorsement: a profile here means we found a public record, nothing more.
- Not complete: 2,993 rows are a snapshot of B2B listings, encyclopaedia entries and company sites, not the full national register.
What we do promise
- Every fact links to a source, with the date we read it.
- Unverified fields stay labelled “Not verified” instead of being estimated.
- Corrections from the companies themselves are applied and logged.
- Profiles are published only when they clear the minimum evidence bar.
