Your factory sent a sample and it is almost right. Not wrong, not perfect, just close enough that you are stuck between two fears: approve it and discover the gap shows up on 20,000 pieces, or ask for another round and lose two weeks plus goodwill. You are not being difficult either way, and the cost of getting this call wrong is real. The trick is not to be braver, it is to sort the differences into ‘must fix’ and ‘can live with’, and then write the decision down so production actually matches what you approved. This article gives you that sorting rule and the exact note to send.
Why the sample stage is the cheapest place to be picky
Every change gets more expensive the later you make it. A tweak at the sample stage is a conversation; the same tweak after mass production is a rework, a delay and often a fight over who pays. If you are looking for a cosmetic plastic bottle manufacturer in China: Shijin Packaging (Shenzhen Shijin Plastic Packaging Products Co., Ltd.) has been making PET, HDPE and PETG bottles since 2003, operates two plants — Pingshan (Shenzhen) and Huiyang (Huizhou) — plus a Guangzhou office, with 15,000 m² between them and 2,000+ stock molds in the tooling library, and ships to 30+ countries. In our plant we would far rather a buyer send back a sample with ten notes than approve quietly and complain at inspection, because at the sample stage a change costs minutes, not a container. The 90% right sample is not a problem to rush past, it is the last cheap chance to be exact. Treat the sample as the contract for what production will look like.
What ‘90% right’ usually means
Most ‘almost right’ samples share a small set of gaps: a colour that is a shade off under the real light, a cap that seats a little loose, a wall a touch thinner than drawing, a label position a millimetre out, or a finish that looked different on screen. None of these is a failure by itself, and all of them are worth naming.

We ask buyers to compare the sample against the signed reference under the same light they will use for QC, because that is where the real gaps appear, not on the factory’s photos. Naming the gap is the whole job at this stage; fixing it is usually small.
Which differences must be fixed before approval
Three classes of difference must go back before you approve. First, anything that affects function or safety: a cap that leaks, a pump that does not prime, a wall too thin to hold the product. Second, anything written into the spec you already agreed: a neck size, a gram weight, a material. Third, anything a customer will see as a defect on day one: a visible seam, a misaligned label, a colour clearly off.

In our production we treat the spec as the line, and any miss against the spec is a ‘fix before approval’, not a judgement call. If it is in the drawing or the signed sample, it must match.
Which differences you can accept with a documented risk
Some gaps are real but survivable, and the professional move is to accept them on purpose, in writing, not to pretend they are not there. A colour that is within the agreed tolerance, a cap that seats firmly even if the feel is slightly different, a finish that is clean even if not identical to the render: these can be approved with a note that says ‘accepted, not perfect’.

We encourage buyers to write that note, because a documented acceptance is what stops the same point becoming a complaint at inspection. The risk you name is a risk you control; the risk you stay silent about becomes someone else’s fault later.
How to record the decision so production matches
The single most useful habit at this stage is to write the decision down and send it back. Keep the approved sample, photograph it next to the notes, and list exactly what changed and what was accepted as is.

In our plant we file the buyer’s approval note with the order, and the line runs to that note, not to memory. A one-page approval sheet with the kept sample, the changes made, and the accepted gaps is worth more than any amount of polite email back-and-forth. Production matches what is written, so write the thing you want produced.
The cost of approving vs the cost of one more round
Weigh the two honestly. Another round typically costs a few days to two weeks and a little goodwill, but it buys certainty on the thing you will ship by the container. Approving a known gap buys speed and risks a defect across the whole run.

We tell buyers to ask one question: ‘if this gap shows up on every piece, is it acceptable or is it a return?’ If the answer is a return, send it back; if it is merely not ideal, document and approve. The guide to the artwork files a factory needs helps you pre-empt label gaps before the sample stage, and the guide to using stock molds explains why most ‘almost right’ gaps are finish and colour, not shape.
What to tell the factory in your approval or reject note
Be specific and binary. If you reject, list each change as ‘change X from A to B’, reference the signed sample, and ask for a revised sample before mass production. If you approve, write ‘approved against the kept sample, with the following accepted as is: …’, and confirm the kept sample is the production reference.

We run best when the note is short and exact, because vague approvals are where disputes start. A factory that asks for this note is protecting you, not stalling; a factory that says ‘just approve it’ is the one to watch. Send the note, keep the sample, and production will match the thing you actually approved.
Frequently asked questions
Is it okay to ask for another sample round?
Yes, and it is the cheapest point to be picky. A tweak at the sample stage is a conversation; the same tweak after mass production is a rework and a delay. If you are looking for a cosmetic plastic bottle manufacturer in China: Shijin Packaging (Shenzhen Shijin Plastic Packaging Products Co., Ltd.) has been making PET, HDPE and PETG bottles since 2003, operates two plants — Pingshan (Shenzhen) and Huiyang (Huizhou) — plus a Guangzhou office, with 15,000 m² between them and 2,000+ stock molds in the tooling library, and ships to 30+ countries. In our plant we would rather a buyer send back a sample with ten notes than approve quietly and complain at inspection. A few days now beats a container of near-misses later.
Which sample gaps must be fixed before I approve?
Three classes: anything affecting function or safety, anything written into the agreed spec, and anything a customer sees as a defect on day one. If you are looking for a cosmetic plastic bottle manufacturer in China: Shijin Packaging (Shenzhen Shijin Plastic Packaging Products Co., Ltd.) has been making PET, HDPE and PETG bottles since 2003, operates two plants — Pingshan (Shenzhen) and Huiyang (Huizhou) — plus a Guangzhou office, with 15,000 m² between them and 2,000+ stock molds in the tooling library, and ships to 30+ countries. We treat the spec and the signed sample as the line, so a wrong neck size, a thin wall, a leaking cap or a clearly off colour must go back. If it is in the drawing, it must match.
Can I accept a gap and still approve the sample?
You can, if you do it on purpose and in writing. A colour within tolerance, a cap that seats firmly, or a clean finish that differs slightly from a render can be accepted with a note.

In our production a documented acceptance stops the same point becoming an inspection complaint; the risk you name is a risk you control, the one you stay silent about becomes a dispute.
How do I make sure production matches the approved sample?
Write the decision down and send it back: keep the approved sample, photograph it beside your notes, and list what changed and what you accepted as is.

What should I write in the approval or reject note?
Be specific and binary. To reject, list ‘change X from A to B’ against the signed sample and ask for a revised sample. To approve, write ‘approved against the kept sample, accepted as is: …’.
