The validity period is stated on the quotation itself and is confirmed in writing with you rather than left open-ended. Treat the stated date as the commitment: within it, the price holds.
Re-quoting is normally triggered by one of three things. A change in specification covering output rating, connector, housing or certification scope, since those change the bill of materials. A significant change in order quantity or configuration that moves the order outside the tier it was quoted against. Or a material-cost movement, particularly in copper and semiconductors, which are commodity-driven rather than something a manufacturer can absorb indefinitely. If your project timeline extends beyond the validity date, tell us and we will re-issue the quotation ahead of time rather than surprising you later.
Private labelling and logo printing are standard services for us. We can apply your brand to the product and to the packaging, and we can agree model naming with you so that labels, certificate copies and test reports reference a model identity consistent with your brand.
The MOQ for private-label production is confirmed with our sales team at quotation stage, because it depends on the housing, the printing process and whether the unit is a standard platform or a custom build. To move quickly, send your logo artwork, the required model naming, your target market and your estimated quantity. Our standard production threshold starts at 100 units, and all projects run under ISO 9001 with 100% factory inspection before shipment.
The direct answer is that the specification behind the price is different, so the useful comparison is on content rather than on the headline number. Several points are directly verifiable. Our products carry a 3-year warranty, with MTBF equal to or greater than 30,000 hours, a 4-8 hour full-load burn-in on every unit, and 100% factory inspection rather than sampling.
We also hold the certifications buyers need across major markets, including UL/cUL, ETL, FCC, TUV-GS, CE, CB, UKCA, PSE, KC, SAA/RCM, CCC, BIS, NOM, RoHS and REACH, with published numbers you can check yourself, such as UL E494677 and TUV/GS S 50527896. Testing runs in our own CNAS-standard EMC laboratory. Share the alternative specification and our sales team will compare the two offers point by point.
Our MOQ is 100 units, a deliberately low entry point for factory-direct supply. You do not need to fill a container to start. For a first order we normally suggest beginning with samples so that you can validate performance and certification coverage before committing to volume; from there, 100 units per model is the standard production threshold.
Fuyuan has manufactured battery chargers, power adapters and LED power supplies since 2005 and has developed more than 3,000 models, so most projects can start from an existing platform rather than a new design. If your requirement sits below 100 units, or involves a special configuration, our sales team will review it case by case at quotation stage.
For Europe we hold CE, covering both the Low Voltage Directive and EMC, plus TUV-GS, CB test certificates, RoHS and REACH compliance. CE and GS are separate certification paths and are reported separately. Chargers are covered by EN 60335-1 and EN 60335-2-29, adapters by EN IEC 62368-1, and LED drivers by EN IEC 61347-1 and EN IEC 61347-2-13.
Our CB certificates are issued to IEC 62368-1 fourth edition, IEC 60335-1 with IEC 60335-2-29, and IEC 61347-1 with IEC 61347-2-13, which makes them useful for approvals beyond Europe as well. The TUV/GS certificate number is S 50527896 and the CE reference is E1403413, both verifiable online. Certificate scope is model-specific, so please confirm the exact model with us.
