An emerging brand sets a target price from a competitor’s product, sends it to a factory, and gets back roughly double. The gap is rarely the factory. Your target was a bottle-body price; the quote is a finished set with a closure, a liner, printing, packaging and freight. Below is where each layer sits.
Quick answer
- A bottle is sold per piece and bought by the kilogram, so empty gram weight decides most of the body price.
- Closures, pumps and liners are separate lines and can rival the body on a dispensing product.
- Your target is only comparable if it names the same eight lines the factory quoted.
How does bottle weight turn into material cost?
A plastic bottle is priced per piece but its main input is priced per kilogram. If one factory builds your 500 ml bottle at 28 g and another at 34 g, the second carries roughly 20% more compound before anything else is counted — and it is also the bottle that will not crease in a full carton. Weight is where a “same” bottle quietly stops being the same bottle, so it needs a written specification and a tolerance. The hidden inputs behind one unit price are listed in why two quotes for the same bottle differ by 30%.
| What changes | Effect on the body price | What to ask for |
|---|---|---|
| Empty gram weight | Dominant — resin is bought by weight | Target weight and tolerance, in writing |
| Material and grade | Virgin and certified recycled are not interchangeable | Resin family, grade, recycled content |
| Wall thickness | Thicker walls add weight without adding capacity | Nominal and brimful capacity stated separately |
| Colour | Standard shades cost less than a custom match | Pantone reference, masterbatch ratio, colour minimum |
| Surface finish | Matte and soft-touch change the tool and the cycle | Finish named per component |
What does the closure, pump and liner add to a finished set?
A pump bottle is not a bottle with a pump attached. The closure is a separate tool, a separate material, a separate colour and a separate minimum order — and on a dispensing product it is routinely the most expensive line on the quotation. Here is a real finished-set breakdown from one of our quotation sheets, for a 100 ml flat HDPE bottle with a PP screw cap and foam liner.
| Quantity | Body EXW | Body FOB | Cap with foam liner | Complete set FOB |
|---|---|---|---|---|
| 5,000 | USD 0.16 | USD 0.19 | USD 0.04 | USD 0.23 |
| 10,000 | USD 0.13 | USD 0.14 | USD 0.04 | USD 0.18 |
| 20,000 | USD 0.13 | USD 0.13 | USD 0.04 | USD 0.17 |
Read the closure share off that table rather than off a headline. At 5,000 pieces the cap is about 17% of the set. On a dispensing product it is far more: a matte black locking 28/410 pump quoted to us at USD 0.13 sits against a 500 ml HDPE body at USD 0.35 at the same tier, so the pump is roughly a quarter of the set before decoration. Liner choice is smaller but real — the same PP cap quoted at USD 0.04 with a PE foam wadded liner and USD 0.042 with an aluminium foil liner.
| Line | Minimum at our factory | Where it usually gets hidden |
|---|---|---|
| Bottle body | 5,000 pieces per model | Rarely — it is the headline |
| Cap / pump / sprayer | 5,000–10,000 pieces | Quoted as “including closure” |
| Liner / insert | With the closure | Assumed rather than specified |
| Decoration | No extra minimum beyond the body | “Printing”, without a pass count |
| Packaging | With the body | Omitted entirely on EXW quotes |
How do one-time colour, print and packaging fees spread across a small order?
Colour matching, artwork setup and packaging are charged once, not per bottle — which is why they hurt small orders. Our colour development and sampling line is USD 200 per colour, and a prototype run is USD 200.
| Order size, one colour | USD 200 colour fee per bottle | What changes |
|---|---|---|
| 5,000 | USD 0.040 | Visible — comparable to a whole decoration pass |
| 10,000 | USD 0.020 | Halves immediately |
| 25,000 | USD 0.008 | Effectively absorbed into the body price |
| 50,000 | USD 0.004 | Rounding error |
Tooling amortises the same way. A standard custom mould starts around USD 1,200 and takes about 30 working days; quoted per cavity it can be USD 900 per cavity, which over 5,000 pieces is USD 0.24 per bottle. That is why a stock mould beats a private mould at low volume — the mechanics are in MOQ, tooling cost and lead time. Colour also carries a material minimum underneath the fee: masterbatch is bought in minimum lots of around 10 kg, dosed at roughly 2% for a normal shade and 4% where strength is needed, with standard black and white carrying a lower minimum. Ten kilograms at 2% becomes about 500 kg of coloured compound, which is the mechanism behind pooling several shades into one run.
Packaging is the quiet line, because ocean freight is charged on volume rather than weight. A bottle shipped with its closure fitted takes materially more space than the same pieces packed separately, and that decision moves your freight bill more than the resin does.
| Line to require on every quote | From a real packing spec | Why it matters |
|---|---|---|
| Pieces per carton | 200 pieces per carton | Sets carton count and pallet count |
| Carton dimensions | 50 × 38 × 40 cm | Container space is calculated from volume |
| Gross weight per carton | 3.7 kg | Terminal handling, and what your forwarder needs |
| Cartons at your quantity | 5,000 pieces = 25 cartons; 20,000 = 100 cartons | Whether you fill a container or pay for half of one |
| Assembly | Bodies and closures packed separately, or assembled | The largest freight lever most buyers never ask about |
How does the MOQ curve flatten, and when does importing beat buying locally?
Every extra piece spreads the same fixed costs — machine set-up, colour changeover, mould fitting, the off-spec metres purged before the process stabilises. So the curve falls steeply at first and then flattens. The useful question is not “how cheap does it get” but “where does it stop falling”.
| Tier | 100 ml flat set, FOB | 500 ml HDPE body, EXW | 65 ml PETG body, bare | What is happening |
|---|---|---|---|---|
| 5,000 | USD 0.23 | USD 0.35 | USD 0.15 | Entry point; fixed costs at their heaviest |
| 10,000 | USD 0.18 | USD 0.31 | USD 0.13 | The steepest part of the curve |
| 20,000 | USD 0.17 | USD 0.28 | — | Approaching the floor |
| 25,000 | — | USD 0.28 | — | Flat against 20,000 on this model |
Two things follow. The 5,000-to-10,000 step is where the money is; the 20,000-to-25,000 step often is not. And the flattening volume differs per model, so ask for 5,000 / 10,000 / 25,000 in writing on every quote. Beyond the unit price sits the rest of the cost: the unit price on a quotation is typically 55–70% of what a bottle costs you by the time it is on your filling line, with freight, duty, clearance, warehousing, defect allowance and working capital making up the remainder.
| Cost layer | Buying locally | Importing from China |
|---|---|---|
| MOQ | Short runs possible | 5,000 per model, 5,000 per colour, 5,000–10,000 per closure |
| Unit price | Higher | Lower, and tiered |
| Freight and duty | Minimal | Charged on volume; duty follows classification and origin |
| Working capital | Days | Weeks in transit and in port |
| Tooling | Often amortised away locally; higher per cavity | One-off, quoted per project, ownership negotiable |
A local supplier sits at the bottom of that stack with almost none of the import layers, and that is its entire advantage. Run both quotes through the same landed-cost model, then weigh the difference against the capital and lead time you are carrying. Below a container-filling annual volume on an unproven range, local buying usually wins on cash and risk; above it, the imported set usually wins on unit cost. The full model is in total landed cost breakdown.
How do you answer “can you hit my target price”?
A quoted price is a statement about resin, labour and currency on one date, and validity windows commonly run 15–90 days. Read the lock condition, not just the date: a price held against resin index, quantity or both are three different promises, and a longer window usually costs money somewhere else — a higher headline, a smaller discount at the higher tier, or a shorter payment term. Currency matters too: a quote in your currency puts the exposure on the supplier, a quote in theirs puts it on you.
The number attached to that question is usually a body price lifted from a competitor’s finished product. The honest answer is a path, and we run the same five steps.
| Step | Ask yourself | What the answer tells you |
|---|---|---|
| 1. Rebuild the target | Does it include closure, liner, printing and packaging — or is it a bare body? | Most target-price failures end here |
| 2. Fix the specification | Capacity, material, gram weight, neck finish, colour? | Without this, no two quotes can match |
| 3. Get the eight lines | Body, closure, liner, decoration, setup, packaging, freight, total | Shows which line makes the target unreachable |
| 4. Test the volume | Which tier is your real first order, and your real annual volume? | Separates a price problem from a quantity problem |
| 5. Check the tool | Does an existing mould fit, or are you paying to create the shape? | Decides whether tooling belongs in this decision |
If the rebuilt target is still out of reach, there are three honest levers and one dishonest one. Raise volume into the next tier. Simplify the specification — stock mould, standard colour, printed differentiation instead of resin colour. Or change the format, because a smaller bottle is a smaller piece of resin. The dishonest lever is thinning the wall until the price appears, and what happens when a quoted weight does not arrive is what follows.
What buyers actually asked us
Real questions from inquiries we handled. Company names, countries and order quantities have been removed, because those are our customers’ business, not ours to publish.
“Please quote the FOB unit price at each of our volume tiers, plus sample cost, sample lead time, bulk lead time and payment terms. We also need a quotation validity of at least 60 days, because our approval process is slow.” — hair care brand, Oceania
“We would rather avoid the cost of new tooling. If there is no existing mould in a similar shape, please tell us what the mould would cost and what unit price you could actually reach. We understand that our requirements and target price may not be fully achievable.” — trading company, East Asia
“Please quote unit price EXW and FOB for the bottle with the cap, at both our trial quantity and our next-quarter quantity. If your HDPE is suitable for acids, alkalis and solvents, please confirm that in writing too. We are ready to place the order as soon as the samples are approved.” — wholesale distributor, Europe
Three mistakes we see every year
1. Comparing a target price to a finished-set quote. A body-only number and a body-plus-closure-plus-printing-plus-carton number are not two prices for one thing; they are two different products. Rebuild the target to include every line before you judge whether it is reachable.
2. Reading the MOQ curve as if it keeps falling. Buyers size their budget on the 25,000-piece tier, then order 5,000, and the set-up costs that were supposed to be spread arrive on a single invoice.
3. Treating quote validity as a formality. A short window with no lock condition tells you nothing about what you will pay when the deposit lands, and the change lands on you at the worst moment. Ask what the price is locked against and in which currency it settles.
What to send your supplier so the cost structure stays visible
Send this once, to every supplier, and require the same eight lines back on the same quantity and the same incoterm:
- Bottle model, material and grade, with empty gram weight and tolerance
- Nominal capacity and brimful capacity, plus neck finish
- Closure, pump or cap by type, with the liner stated separately
- Unit price at 5,000 / 10,000 / 25,000 pieces
- Colour: Pantone reference, masterbatch minimum, colour setup fee per shade
- Decoration: method, colour count, passes and the artwork version priced against
- Packaging: pieces per carton, carton dimensions, gross weight, and whether closures ship assembled
- EXW and FOB on the same quantity, quote validity with its lock condition, and payment terms
If a supplier cannot fill in all eight lines, you are not comparing products — you are comparing answers.
Frequently asked questions
What is the minimum order quantity for a plastic bottle?
5,000 pieces per bottle model and 5,000 per colour at our factory, with closures typically starting at 5,000–10,000. Below 5,000 the unit price rises because set-up costs are fixed, and the right answer is usually a stock shape with decoration.
How much does the closure add to the bottle price?
On a screw-cap set, often a sixth to a quarter of the finished set. On a dispensing product a pump can rival the body — a matte black locking 28/410 pump quoted to us at USD 0.13 against a 500 ml body at USD 0.35.
Why does a lighter bottle quote cheaper?
Because resin is bought by weight and the bottle is sold by the piece. A thinner bottle uses less compound but is more likely to crease or crack in transit. Specify a gram weight and a tolerance rather than accepting the lightest quote.
How long is a bottle quotation valid?
Commonly 15–90 days depending on the supplier and the resin outlook. Ask what the price is locked against — resin index, quantity or both — and in which currency it settles.
When is new tooling worth paying for?
When you need a distinctive shelf silhouette, when exclusivity matters, or above roughly 20,000 pieces a year. New tooling takes about 30 working days from drawing approval.
Does buying locally ever beat importing from China?
Often, below a container-filling annual volume on an unproven range, because you carry no freight, duty, clearance or five weeks of working capital. Run both through the same landed-cost model.
