Brazil landed cost calculator<\/a> before deciding \u2014 duties and local costs often change which order size actually wins.<\/p>\nYour MOQ, sampling and lead-time RFQ checklist<\/h2>\n
Put these points in writing before you sign. MOQ per model, and whether it holds across colorways and plug variants. Sampling window, and what the sample price includes versus the separate tooling and certification lines. Mass production window from approved sample, and the stage that sets it. Who owns tail-lot components. Pilot scope, and whether pilot units pass the same 100% ATE functional test and burn-in as production. Certification scope actually held \u2014 CE, CB, FCC, RoHS, ErP and ISO 9001 as standard, with UL\/ETL\/UKCA funded per project \u2014 and the USB PD 3.2 design basis stated as a specification, not a certification.<\/p>\n
Reorder terms belong in the same document: the frozen BOM, the test limits and the change-control path, so a substitution can never happen without your approval. A supplier who publishes these numbers before being asked has usually already lived through the failures they prevent. Collect the three numbers \u2014 MOQ, sampling, lead time \u2014 from every candidate on your list, and the differences will tell you more than any brochure.<\/p>\n
Frequently asked questions<\/h2>\n
These are the OEM charger MOQ, sampling and lead-time questions buyers ask most, answered without the sales gloss.<\/p>\n
What is a realistic OEM charger MOQ?<\/h3>\n
Plan around 200 pcs per model for a modified standard build and 500\u20131,000 pcs for a full custom ODM design. Catalog white label units carry a lower minimum, typically 100\u2013200 pcs, because nothing is engineered. Any quote dramatically below those floors is not a bargain \u2014 it is a signal to ask which gate has been removed, because component reels, changeover and per-model qualification cost the same regardless of batch size.<\/p>\n
Why is the OEM charger MOQ 200 pcs per model?<\/h3>\n
Because 200 is roughly where three fixed cost floors balance out. Component vendors ship in reels and minimum lots sized for volume, a model changeover costs nearly the same whether the batch is 200 or 2,000, and per-model qualification \u2014 certification, incoming inspection, frozen BOM, test limits \u2014 exists once the model exists. Below that floor, the per-unit share of fixed work distorts the economics, which is why a credible MOQ tracks real cost rather than a round marketing number.<\/p>\n
Who pays for tooling, NRE and certification?<\/h3>\n
The buyer carries development, tooling and certification fees on a modified standard or custom build, quoted as named line items before the order. That is the honest structure: those costs exist the moment a model exists, whether or not it ships in volume. A supplier who folds them into the unit price has to recover them somewhere, and the model becomes hard to move later. White label catalog units are the exception, since nothing is engineered for you.<\/p>\n
How long does a sample take?<\/h3>\n
About 7 days for a modified standard build, because the platform exists and the work is re-tuning \u2014 output profile, connectors, housing details. A full custom ODM sample takes 2\u20134 weeks, since schematic capture, layout and first tooling shots all sit in the path. What moves the number most is rarely the bench: a frozen BOM, in-stock connectors and one named approver on your side each save days, while a drifting spec quietly costs a week per loop.<\/p>\n
Why does mass production take 5\u20136 weeks?<\/h3>\n
The window is structural. Material purchase \u2014 long-lead components and housing molding \u2014 sets the earliest assembly date, typically 1\u20132 weeks. Assembly with 100% ATE functional testing and burn-in at rated load follows, and that gate is finite capacity that cannot be compressed without gambling on field failures. Packing, artwork approval and freight booking close the path. The total from approved sample to shipment is 5\u20136 weeks, and a materially shorter promise deserves scrutiny, not applause.<\/p>\n
Can the OEM charger MOQ be split across colors or plugs?<\/h3>\n
Colorways on one electrical build can typically share the 200-pc minimum, because the platform, BOM and certification file are common and only cosmetic variants change. Different plug types are a different matter: each plug usually changes the model, the test setup and sometimes the certification scope, so each variant normally meets the OEM charger MOQ on its own. Ask the question per configuration at RFQ, in writing, and get the split rules confirmed before the pilot run.<\/p>\n
What is included in the sample price?<\/h3>\n
The sample build itself, the engineering time to tune it to your spec, and the test data that proves it: ATE results for output voltage and current, ripple, regulation and protection-trip behavior, measured against production limits. What sits outside the sample price is the tooling, the certification scoping and the packaging plates, which are separate line items by design. Ask for that breakdown in writing so the quote compares cleanly across suppliers.<\/p>\n
Are reorders faster than the first order?<\/h3>\n
Yes, and measurably so. A reorder skips development, sampling and tooling entirely because the BOM is frozen, the test limits are set and the tooling is already paid for. It typically lands at the faster end of the same 5\u20136 week production window, since the material buy starts from a known-good list and the line is already qualified for the model. The 100% test and burn-in gate does not relax, which is exactly why the speed is safe.<\/p>\n
How do I keep MOQ low without raising unit cost?<\/h3>\n
Work the levers that shrink fixed per-model work. Consolidate SKUs so one platform carries several marketing versions. Keep colorways on one electrical design. Accept tail-lot components for model-specific parts. Commit volume across quarters with a staged delivery schedule instead of demanding it all at once. What does not work is pushing the number down while changing nothing else \u2014 the cost does not disappear, it moves into the unit price or out of the quality gates.<\/p>\n
