Note 03

China or a US plant, compared honestly

We are a Chinese plant, so read this with that in mind. Three rows below go against us, and the last section tells two kinds of buyer to go elsewhere. A comparison that never loses is an advertisement.

By dimension

Where each side wins

Dimension	US plant	Chinese plant	Edge
Familiarity with state feed rules and retail audits	Works inside them daily	Learns your market's rules per order	US
Certification schemes retailers ask for	Often already holds them for its site	Holds what its own market requires, and issues the rest at order	US
Lead time, order to door	Days, no ocean	Adds 3–6 weeks of transit and clearance	US
Unit cost at volume	Higher labour and overhead	Lower, at the same specification	China
Minimum order	A 300-unit run is usually a bench batch, not a production order	300 units on three of four formats, because standard containers need no tooling	China
Format breadth on one file	Often a specialist in one format	Chew, softgel, tablet and powder from the same specification	China
Changing your mind	Change orders carry US labour cost	Cheaper to re-run, which matters most in the first year	China
Time-zone communication	Same hours	A working overlap, not a full day	US
Perceived risk to your retailer or broker	Lower, rightly or not	You carry the burden of proof	US

The real variable

Certificates are paperwork; release data is the product

The comparison above is mostly about documents and distance. Neither is what makes a batch fail. A batch fails because the overage was too thin, the shell was substituted, or the label made a claim the product cannot support in that market — and all three happen on both sides of the Pacific.

So the useful question is not “which country”. It is: who releases the batch, against which specification, and will you see the numbers before it ships. A factory that answers that clearly is the lower-risk choice regardless of where it stands.

Choose by buyer

Which buyer should pick which

Pick a US plant if

Your retailer audits the manufacturing site and will not accept an overseas report.
You need stock in weeks and the product already sells.
Your volumes are large enough that the unit-cost gap stops paying for the transit and the added documentation work.

Pick a Chinese plant if

You are launching and the first order has to be small enough to survive being wrong.
You want one supplier across several formats instead of several suppliers across one format.
Your margin cannot absorb a US unit cost at your retail price, and the documentation burden is something you are willing to run.

If you are between the two, the cheaper test is a sample from each, released against the same specification. Two samples cost less than one wrong production order.

Questions

Asked about this note

Is a US factory always safer for a US brand?

Safer on paperwork, not automatically on product. A US plant already works inside the state feed rules and the retailer audit regime, so there is less translation risk. What it does not guarantee is your formula being run the way you specified, which is what a released COA and a first-article approval actually test.

What does a Chinese plant do better than a US plant?

Format breadth, minimum order flexibility and the cost of changing your mind. The same production file can run as a chew, a softgel, a tablet or a powder, and a trial of 300 units is economical. In the US, a 300-unit run usually means a bench batch, not a production order.

If my retailer audits the factory, does that rule out China?

It rules out plants that have not been audited before, wherever they are. Ask for the last third-party audit report and its date, then ask whether the retailer accepts that scheme. If the answer is no, we would rather tell you at the quote stage than after you have paid for a sample.

Test both, against one specification

Send the specification and we will quote a sample against it, with the release panel named, so the comparison is between products rather than between brochures.
