If you are sourcing custom bags for a brand, retail chain, or promotional campaign, understanding how the OEM/ODM process actually works will save you time, money, and a lot of back-and-forth emails.
This guide walks through the full process at Shenzhen Oneier Technology Co., Ltd — from your first inquiry to final shipment — and explains what you should prepare at each stage.
Shenzhen Oneier is a bag OEM/ODM manufacturer and trading company based in Longgang, Shenzhen. We have manufacturing experience since 2007 (company registered 2016), with 500+ workers, 10+ production lines, and a capacity of 5,000 pcs/day (2022 figure). Our main markets are Western Europe, North America, and Northern Europe.
OEM vs. ODM: What's the Difference?
Before the process starts, it helps to know which model fits your project.
- OEM (Original Equipment Manufacturing): You bring the design, specs, and branding. We manufacture to your requirements.
- ODM (Original Design Manufacturing): You start from our existing designs or product catalog, then customize materials, colors, logos, and packaging.
Many buyers use a mix of both — starting with an ODM base and customizing it into an OEM product over time. Shenzhen Oneier supports both. We also offer buyer labels, design capability, and OEM production for established brands. Specific process steps, including material sourcing, printing, stitching, and quality control arrangements, are discussed and confirmed per project.
Step 1: Inquiry and Specification
The process starts with your inquiry. To get an accurate quote, prepare:
- Product type — for example, a neoprene cooler bag, drawstring gym bag, or PU leather cosmetic bag.
- Target quantity — this affects unit pricing and MOQ eligibility.
- Materials — neoprene, polyester, Oxford, nylon, PVC, PU, cotton-canvas, EVA, or TPU.
- Size and dimensions
- Logo and branding method — share your artwork and we will confirm the suitable method.
- Target market and use case — business retail, e-commerce, boutique stores, corporate branding, or event promotions
- Reference photos or samples (if available)
You do not need a perfect tech pack at this stage. A clear description plus reference images is enough to begin. Our team replies to inquiries within 12 hours, and we offer free samples plus a free Pantone color card to support your development.
If you have a branding or decoration requirement — sublimation, silk-screen, heat transfer, digital printing, embroidery, rubber or PVC patches, woven labels, custom zipper pulls, or custom packaging — share your artwork and we will confirm the suitable method. Sublimation is only applicable to compatible fabric surfaces; we will confirm suitability for your chosen material.
Step 2: Design and Artwork
Once the product direction is clear, we move into design and artwork.
If you already have a tech pack, our team reviews it for manufacturability and flags any issues — material availability, stitching limitations, or hardware that may not hold up in mass production.
If you do not have a tech pack, we can help develop one. Our design capability covers:
- Product sketches and structural drawings
- Material recommendations based on your price target and use case
- Logo placement mockups
- Color matching using Pantone references
For ODM projects, we can also suggest modifications to an existing design to better fit your market or hit a specific cost target.
Step 3: Sampling
Sampling is where the product becomes real — and where most issues get caught before bulk production.
Typical sampling flow:
- Spec confirmation — finalize materials, dimensions, colors, and logo method.
- Sample production — we produce a physical sample for your review.
- Sample review — you check fit, finish, stitching, logo quality, and function.
- Revisions — if changes are needed, we revise and resubmit.
- Approval — you sign off on the final sample, which becomes the production standard.
Free samples are available. Sampling timelines depend on the complexity of the bag and the materials involved. Simple items like can coolers or drawstring bags move faster; structured bags like golf staff bags or travel duffels take longer.
What buyers should prepare for sampling:
- A clear reference sample or detailed photos
- Logo files in vector format (AI, EPS, or PDF)
- Pantone color codes for any custom colors
- Any compliance or labeling requirements for your market
Step 4: MOQ and Quotation
MOQ is confirmed per specification and customization in your quote. Because MOQ varies by product, always confirm it during the inquiry stage. Do not assume a single site-wide MOQ applies.
Quotations are based on quantity, materials, logo method, packaging, and shipping terms. Reference price ranges for our current products include:
- Neoprene cooler bags and bottle insulators: $0.15–$4.59
- Neoprene laptop sleeves (11–15.6"): $0.32–$2.99
- Drawstring gym bags with custom logo: $0.09–$1.89
- Travel gym duffels (neoprene): $5.89–$9.99
- Golf staff bags (900D Oxford): $13.89–$26.79
- Golf headcovers and ball bags (neoprene): $0.72–$2.59
- PU leather cosmetic bags: $0.75–$2.29
- Canvas tote bags (custom printed): $0.89–$7.99
- Nylon backpacks and school bags: $5.59–$7.19
- PVC clear stadium-approved bags: $0.89–$6.79
These are reference ranges only. Your final price depends on your specifications.
Step 5: Bulk Production
Once the sample is approved and the order is confirmed, bulk production begins.
Production steps typically include:
- Material sourcing and inspection — fabrics, zippers, webbing, hardware, and foam are checked before cutting.
- Cutting — panels are cut to the approved pattern.
- Printing or embroidery — logos are applied before assembly where possible; the suitable method is confirmed per project based on your artwork and materials.
- Sewing and assembly — bags are stitched, zippers installed, and hardware attached.
- Finishing — trimming, cleaning, and hardware checks.
Shenzhen Oneier runs 10+ production lines with a capacity of 5,000 pcs/day (2022 figure). Our factory covers 10,000–30,000㎡, and our QC team of 5–10 people monitors production throughout the run.
Timelines depend on order quantity and customization. A simple repeat order moves faster than a first-time custom project with new materials and hardware.
Step 6: Quality Control
QC is built into the process, not bolted on at the end.
Our QC team checks:
- Incoming materials — fabric weight, color consistency, and hardware quality
- In-line inspection — stitching, measurements, and logo placement during production
- Final inspection — finished goods are checked against the approved sample before packing
If you have specific AQL standards or third-party inspection requirements, tell us during the specification stage so we can plan for it.
Certificates available upon request.
Step 7: Packaging and Shipping
Packaging options range from simple poly bags to retail-ready packaging with hang tags, barcodes, and custom boxes. Confirm your packaging requirements early — it affects both cost and production time.
Shipping methods include:
- Sea freight — best for large, non-urgent orders
- Air freight — faster, higher cost
- Express courier — for samples and small urgent orders
We ship to Western Europe, North America, Northern Europe, and other regions. Shipping terms (FOB, EXW, DDP, etc.) are confirmed during quotation.
What Buyers Should Prepare
To move smoothly through the OEM process, prepare these items before or during your first inquiry:
- Tech pack or detailed product description — including dimensions, materials, and construction notes
- Logo files — vector format preferred (AI, EPS, PDF)
- Pantone color codes — for any custom colors
- Target quantity and target price
- Reference samples or photos
- Compliance requirements — labeling, testing, or market-specific rules
- Packaging requirements — poly bag, retail packaging, or custom box
The more complete your brief, the faster we can quote and sample.
Common Mistakes to Avoid
- Assuming a single MOQ applies to all products. MOQ varies by item — confirm it early.
- Skipping the sample stage. A physical sample prevents expensive mistakes in bulk.
- Providing low-resolution logo files. Vector files produce cleaner results.
- Leaving packaging decisions to the last minute. Packaging affects cost, timeline, and shipping.
- Not confirming compliance requirements upfront. Different markets have different rules.
