1. What is OEM? How it differs from ODM [quick reference]
OEM (Original Equipment Manufacturing) is a method in which a factory manufactures a product based on your own design and specifications. Here is how it differs from the similar ODM.
Manufacturing commissioned on your own design
You create the product design, spec sheet and tooling yourself, and ask the factory to do only the "manufacturing." You can reflect the brand's preferences 100%.
Design also commissioned to the factory
The factory handles the product's design and development as well. Because existing tooling and know-how can be reused, initial costs are kept lower.
2. The China OEM production process [8 steps]
Product planning and finalizing specifications
Work out what product you want to make — size, materials, colors, quantity and target budget. Even just an idea is fine.
Finding a factory
Select a factory that fits your product category. From allallbuy's 14-year network, we introduce trustworthy factories.
Getting quotes
Collect and compare quotes from multiple factories on mold fees, materials, processing and MOQ (minimum order quantity). All costs are clarified in advance.
Sample creation and confirmation
Before mass production, a sample is made and its quality and finish checked. If revisions are needed, we negotiate with the factory and adjust.
Contracting and ordering
Unit price, delivery date and quality standards are fixed in writing before ordering. allallbuy handles checking the Chinese-language contract and negotiating on your behalf.
Mass production and progress management
We check progress on the production line and resolve issues on the spot. We also handle package printing and label processing.
Inspection
Before shipment, local staff inspect quantity and quality. If defects are found, we negotiate exchanges or re-manufacturing with the factory.
International shipping and arrival in Japan
We ship by the best method from air or sea freight, delivering to your home, warehouse or EC fulfillment center.
3. 5 checkpoints for choosing a factory
Track record and equipment
Does it have experience making the same category of product? Check the factory's scale and equipment (machinery, inspection system).
Languages and communication
Can they handle English or Japanese? Support from local staff is reassuring for working out fine-grained specifications.
MOQ (minimum order quantity)
What is the smallest order they accept? Whether a test order is possible is also an important deciding factor.
Delivery track record
Any history of missed deadlines? It's also reassuring to check their production capacity during busy seasons.
Certifications and quality standards
Can they obtain the required certifications (CE, FCC, etc.)? Confirm they can produce to meet the regulations of your export destination.
4. How costs work [mold, materials, processing]
China OEM costs mainly break into four parts. The composition varies by product, but get the full picture in advance.
| Cost item | Details | Typical estimate |
|---|---|---|
| Mold / tooling fee | Cost of making the tooling to produce the item. One-time only. | Tens of thousands to hundreds of thousands of yen |
| Materials cost | Cost of the product's materials and components | Varies by product |
| Processing fee | Labor for production and assembly | Often included in the unit price |
| Management & overhead | Factory management costs, packing | Often included in the unit price |
| International freight | China→Japan shipping (air or sea) | Settled at actual cost |
5. Risks and countermeasures [quality, delivery, IP]
Quality differs from the image
The mass-produced goods look very different from the sample... Color and material mismatches are a classic trouble with overseas orders.
Countermeasure: approve the sample before mass production → insert inspection steps during production and before shipment.Delays to delivery dates
During busy seasons or material shortages, deadlines slip and disrupt your sales plan.
Countermeasure: build slack into the schedule + check progress regularly.Design leaks or is copied
The risk of your own design being reused by others. Protecting intellectual property is important in China too.
Countermeasure: NDA (non-disclosure agreement) + consider registering trademarks and designs in China.Negotiations break down over language and culture
Subtle gaps in nuance can affect quality and price negotiations.
Countermeasure: put a partner fluent in both Japanese and Chinese (allallbuy) between you and the factory.6. allallbuy's OEM support
