What 500-Piece MOQ Actually Gets You

500 pieces is the real minimum for custom-branded vacuum flasks at a quality factory. Some factories advertise 200 pieces — but at that quantity, they can't run a dedicated painting line or maintain color consistency. You end up with batch-to-batch variation that generates returns.
At 500 pieces, you get: your logo (silk screen, laser, or heat transfer), your specified Pantone color, your packaging choice (PE bag standard; color gift box as upgrade), and full certification documentation. All of that is included at MOQ.
What you're not getting at 500 pieces: custom mold tooling (requires 1,000+ to amortize), a unique shape that doesn't exist in our catalogue (that's ODM and needs tooling investment), or payment terms beyond 30% deposit / 70% balance.
Choosing the Right Logo Method at MOQ

At 500 pieces, every logo method is available except electroplating — which requires larger volumes to justify setup.
Silk screen: Best value at MOQ. 1–3 colors. Setup charge applies but amortizes quickly. Submit vector AI/EPS/PDF files. Best for logos with clean edges and solid fills.
Laser engraving: Slightly higher unit cost but no setup charge. Permanent. Works on both bare metal and painted surfaces. The premium choice for corporate gifts.
Heat transfer: Higher setup cost that's harder to amortize at 500 pieces. Consider it for 1,000+ pcs unless your design genuinely requires it.
UV printing: Available at 500 pieces. Best for photo-quality or gradient-heavy designs.
The Full Cost Breakdown: 500-Piece Custom Vacuum Flask

A realistic budget for 500 custom vacuum flasks (TI-1135, 500ml, one color, silk screen logo):
Unit cost FOB Yongkang: $4.80–5.50 depending on color and complexity. Setup charge (silk screen, 1 color): $30–60. Sample production (if required first): $18–35/pc refundable.
Total for 500 units: approximately $2,450–2,820 FOB Yongkang.
Add: freight (LCL to US West Coast $280–400), customs duty (~5%), import broker ($150–200). Landed cost per unit in the US: approximately $6.80–8.20 depending on location.
Retail price for a quality branded vacuum thermos in the US: $22–45. There's your margin.
OEM basics: what you are actually buying at 500 pieces
What OEM Actually Means in Drinkware
OEM — Original Equipment Manufacturing — in the drinkware context means you take an existing factory design and put your brand on it. You don't need to design anything. You pick a model from the factory's catalogue, choose your color, submit your logo, and the factory produces it with your branding.
This is the entry point for most importers, brand owners, and Amazon sellers. It's the lowest-risk, fastest way to launch a branded product. MOQ at Jupeng is 500 pieces per design — that's 500 units of one color, one logo combination.
Choosing the Right Flask Design
The most important variable in your OEM flask is the design you choose. Once you've placed a bulk order, changing designs means a new mold deposit. So choose carefully.
Key considerations: What capacity do your customers need? 500ml is the universal bestseller — fits car cup holders, is the Goldilocks size for a full day. 750ml and 1L are growing, especially for fitness and outdoor.
Lid type matters more than most buyers realize. The leak-proof guarantee lives or dies with the lid design. Request a sample lid with a full stress test before approving.
Artwork and Logo Submission
The artwork submission process is where most OEM projects slow down. To avoid delays:
For silk screen printing: submit AI, EPS, or PDF vector files. Minimum 2pt stroke width. Full CMYK color breakdown for each color. We'll return a print layout on the bottle outline within 24 hours.
For laser engraving: any format works since we convert to our laser software. Higher contrast logos work best.
For full-color heat transfer: minimum 300 DPI bitmap or vector. Provide a complete color profile.
Sample Process — 7 to 10 Days
Ordering a sample is non-negotiable before bulk production. It's the only way to verify color, logo placement, lid function, and packaging before committing to 500+ units.
Our sample process: you confirm the model, color, capacity, and send your logo. We produce one or two samples in 7–10 business days and ship DHL/FedEx Express to your door.
Sample cost is at manufacturing cost — typically $15–40 per sample depending on complexity. 100% refundable against your first bulk order of 1,000+ pieces.
When to Go Above 500 Pieces

500 pieces is the right size for market testing — you're validating a SKU before committing to inventory investment. Once you've validated demand, there's a strong argument for scaling to 2,000+ pieces.
At 2,000 pieces: unit cost drops 15–20%, custom Pantone matching is included at no extra charge, better packaging options become cost-effective.
At 5,000+ pieces: custom ODM mold tooling becomes affordable to amortize, you can afford a dedicated production run with tighter tolerances.
Most successful Amazon sellers we supply started at 500 pieces, tested 3–4 colorways, identified the 1–2 that moved, and scaled those to 2,000–5,000.
