MOQ depends on the level of customisation: 500 pcs per model for stock models with no customisation, 1,000 pcs per model for a custom logo or colour (OEM), and 3,000 pcs per project for full ODM with new tooling. Mixed-SKU orders may combine colours on one model to reach the MOQ tier.

Yes. Mixed-SKU orders may combine colours on one model to reach the MOQ tier. Mixing different models inside one production run is quoted per project — send us the split and we will confirm what the lines can take.

Send your target market, estimated quantity and the level of customisation you need. The export sales team replies within one business day with a quotation and the current capacity schedule.

A sample of an existing model with your custom logo ships in 7–10 working days. A new ODM tooling sample takes 20–25 working days, because the mould has to be cut first.

The sample fee is credited against the first bulk order, so sampling does not add cost if the project goes ahead.

Every project runs Brief, Design, Sampling, Approval, Production: your brief is quoted, the artwork and specification are confirmed, a golden sample is made, you approve it with the document pack, and mass production follows with per-batch checks.

The product lines are specified against CE, FCC, RoHS, UN38.3, IEC 62133, ISO 9001, BSCI and MSDS requirements. This demo site lists certification types only and shows no certificate numbers, laboratories or issuing bodies.

Yes — buyers receive a standard export documentation pack covering the CE, FCC, RoHS, UN38.3 and ISO 9001 requirement types for the destination market. On this demo site the pack is described, not published.

BSCI is one of the compliance types listed for the facility. Because this demonstration publishes document types only, no audit reports or registrations are shown here.

Yes. Every battery shipment is prepared with UN38.3 test summaries and MSDS/SDS documentation, and packed according to the carrier's dangerous-goods rules.

Three: the UN38.3 test summary for the battery as shipped, the MSDS/SDS for the cells, and the transport appraisal report prepared for the booking. Finished warmers are classified as UN 3481, lithium-ion batteries contained in equipment.

Airlines commonly allow warmers with built-in batteries in carry-on baggage and require spare lithium batteries to travel in carry-on only, never in checked luggage. Rules differ by airline, so confirm with the carrier before flying.

Standard orders of up to 50,000 pcs take 25–30 days, and larger or fully custom orders take 35–45 days — both counted from sample approval and deposit.

Peak season runs March to June and may add 5–7 days to production lead times; the applicable timing is confirmed in the proforma invoice.

The demo factory is set at 300,000 pcs per month across six production lines in an 8,000 m² facility. Figures are illustrative for this student project and are not a capacity commitment.

A 12-month limited warranty covers all hand warmer units against manufacturing defects, counted from the bill of lading date. Confirmed defective units reported within 30 days of delivery are replaced free of charge.

Claims are handled by the export sales team. Report the issue with photo or video evidence; confirmed manufacturing defects inside the warranty window are replaced, and the 30-day defect window is counted from delivery.

Batteries, normal wear, accidental damage and unauthorised modification are excluded from the 12-month limited warranty.
