The Car Models family example
The commercial description below is the representative description for this family only, transcribed from the official site's representative page for this family. It is a family example, not a site-wide rule, and it must not be read as applying to any other family, because each family's commercial terms are confirmed per family, in the inquiry.
For the car models family, the representative description states a minimum order of 1000 pcs for diecast metal and plastic material, and 500 pcs for resin material, as stated on the official site's representative page for that family. For the motorcycle family, the representative description states a minimum order of 1000 pcs. For the space and airplane and cartoon character families, the representative descriptions state a minimum order of 1000 pcs for diecast metal and plastic material, and 500 pcs for resin material. Those figures are family examples, each for its own family, and they are not site-wide rules, because each design's minimum is confirmed per design, in the inquiry.
A buyer who wants another family should not assume its minimum from these examples, because families differ in material, in scale, and in production, and because a minimum that fits one family may not fit another, however similar the families appear. Confirm the minimum for your design, in writing, before payment, because a minimum confirmed after payment is a minimum that cannot be relied on.
Why minimums differ, and why template differences matter
Minimums differ by material, because some materials require larger runs to be economical, and by design, because some designs require more mold work, more hand work, or more finishing than others, and because a manufacturer that accepts a small order for one design may require a large order for another, where the setup cost differs. The official site's descriptive pages show this in their template differences: most descriptive pages carry a minimum order field, while a minority do not, and a page without a minimum field is not a page with a zero minimum, nor a page whose minimum can be assumed from another page, because a missing field is a missing fact, not a zero, and because a figure stated for one page must not be extended to a page that does not state it.
That is the rule this site follows: a page with a minimum field states its minimum, with attribution, and a page without one states no minimum, and refers the minimum to the inquiry, rather than assuming it from another page. A buyer who reads a minimum from one family's page as applying to another family has misread, and a buyer who asks for the minimum for their design, in writing, will receive the figure that applies.
What to confirm, in the inquiry
Name the design, the material, the scale, the quantity you have in mind, and the market you sell into. Ask for the minimum order quantity for that design, in writing, with its unit: pieces, and whether the minimum counts per design, per material, or per order, because a minimum stated in one unit is not the same as a minimum stated in another. Ask for the lead time with its meaning, the payment and shipping terms, the mold ownership terms, the packaging options, and the certificates that apply to your market, by name, with documents attached. Confirm the minimum in writing, before payment.
Before payment, confirm the minimum order quantity, lead time, payment, shipping and mold ownership terms for your order. Certificates are available upon request.
