Notes from the factory floor

The facts scattered across this site, assembled into something you can use: how MOQ is calculated, how to audit a Vietnamese factory, where the cost difference sits. Every piece carries its basis and its source; corrections are made in place, not deleted.

MOQ & sampling

Cosmetics OEM MOQ: From 50 kg to 2,000

Three floors in one plant: 50 kg baby care, 500 kg care line, 2,000 units fragrance. How the units split and how the conversion really works.

How these notes are written

Two pieces are not written yet, and why: "Vietnam vs China: where the cost difference actually sits" needs a cost breakdown the plant can make public; "FDA / LFGB / CE: what to prepare" needs legal confirmation of current requirements in each market. We do not have either to hand, so they wait — nothing on this site goes up without a source.
Have a specific question? Send it. If it is not covered here, we still answer.
Three lines, and the first reply can answer you
  1. CategoryWhich category, or simply "like that product of yours" — more useful than a formula name
  2. VolumeRoughly how many units or kilograms, per SKU
  3. MarketThe destination decides access and labelling — one formula going to the EU and to the US is not one set of documents

You get three answers back: whether it is feasible, the MOQ, and how sampling works. If it does not fit our lines, we say so in the first email instead of the third meeting.
