Packaging spec builder:
formula, volume and quantity in — a sourcing spec sheet out.

Six questions, two minutes. The builder applies the same rules a sourcing engineer applies to a brief — which materials your formula allows, which neck and closure the format takes, what your target look does to the minimum, how many days the route really needs — and writes a 12-line spec sheet you can copy or send to Vella in one click.

Short answer

A cosmetic packaging spec sheet needs 12 lines: product, fill volume, primary format, material, neck finish, closure or pump with its dose, decoration, colour reference, quantity per SKU and number of SKUs, target price, market and label needs, and launch date. The material line is decided by the formula before anything else — ethanol above ~30% rules out PET, pH below 4 means glass or PP, oxygen-sensitive actives mean amber glass, airless or a 5-layer EVOH tube — and the quantity line decides the route: about 500 for an undecorated stock part, 2,000 with a screen-printed logo, 2,000–5,000 per shape for sprayed colour, ~10,000 for airless and electroplated parts, 30,000+ for made-to-order glass. Lead time is the route's factory-gate figure × 1.3, +15 days across Chinese New Year, plus sea freight.

What the builder is doing, line by line

A packaging quote is only as good as the brief behind it. A supplier who has not been told your alcohol percentage, your pH and your key actives has quoted a shape, not a package; a supplier who has not been told the quantity per SKU cannot say whether the route is stock, stock plus decoration or a private mould. The builder forces those twelve facts into one sheet and applies the rules below in order: formula decides material, format decides neck and closure, look decides the decoration process and its minimum, quantity decides whether you clear it, and route plus calendar decides the order-by month.

The rules the builder applies

Every figure comes from the formula × packaging compatibility matrix, the MOQ index 2026 and the lead time index 2026. Minimums are indicative, per component, and reachable through partner factories already tooled for small runs; the published industry floor is 5,000–10,000 pieces per item.

How the decoration line moves your minimum

The look you choose is a machine set-up somewhere, and the size of that set-up is the floor. A full-wrap label or digital sleeve on a stock bottle starts at about 100–500; screen print at 2,000 (the decorating line's minimum, not the artwork's); frosting on a stock glass shape from about 1,000; sprayed custom colour 2,000–5,000 per component shape, because different shapes cannot be hung and sprayed together; anodised custom tones on aluminium collars around 10,000; electroplated closures ~10,000, not moved by any supplier; moulded-in colour 5,000–10,000; a new mould 3,000–10,000 pieces plus RMB 25,000–70,000 of tooling; made-to-order glass 30,000–200,000. Two ways under the numbers: move the colour to the label, or treat decoration as one programme across SKUs — six products of 2,000 sharing one shape and finish present the line with 12,000. Details on the decoration process comparison.

How the lead-time line is calculated

The builder uses the factory-gate cycle for your route from the lead time index — stock plastic 7–25 days, +5–7 for print or hot stamp, 30–40 for sprayed colour, 20–30 for stock airless, 15–20 for tubes and printed pouches, 30–60 for glass, 25–40 for anodised aluminium, 35–50 for PCR stock formats, 90–120 for a private-mould programme — multiplies it by 1.3 (the quoted cycle is the plan; the buffered cycle is the promise), adds 15 days if the production window touches Chinese New Year (6 February 2027; 26 January 2028), then adds sea freight port to port — 18–25 days to the US West Coast, 30–35 to the UK and Northern Europe, 20–25 to Australia — plus 5–10 days of clearance at each end. Sampling (7–10 days for stock samples, 10–14 for sprayed samples, 2–4 weeks for decorated samples on an existing mould) sits before the order and is not inside the figure. Sizes and their US fluid-ounce equivalents are on the bottle size guide; ml, fl oz and gram conversions on the unit converter.

Worked example: 30 ml vitamin C serum, 3,000 pieces, frosted, US, launch March

Spec lineWhat the builder writesWhy
Primary format30 ml high-flint glass bottle, frosted, 18/400 neck; alternative PP/PETG airless 30 mlSerum on 18/400 or 20/400 glass; vitamin C is oxygen-sensitive, so frosted clear glass needs a carton or the airless alternative
ClosureGlass pipette dropper, silicone bulb, 18/400 collarSilicone over TPE for aggressive actives; the bulb is the weak point
Compatibility flagsOxygen-sensitive: no clear PET dropper; amber/opaque glass, airless or EVOH; 48°C / 30-day test on the actual bulkOxidation browns vitamin C; the compatibility matrix rule
Decoration and MOQAcid-etch frosting on a stock shape, floor ~1,000; screen-printed logo, floor 2,000; 3,000 clears bothFrosted stock shapes from ~1,000; print 2,000; keep print + hot stamp to ≤2 passes
Lead timeGlass 30–60 days + print 5–7 = 35–67 quoted; × 1.3 = 46–88 buffered; + 15 CNY = up to 103 factory gate; + sea 18–25 + clearance 5–10 to the US West CoastA March 2027 launch runs through the 6 February 2027 holiday, so the +15 applies
VerdictOrder by mid-October 2026 — golden sample signed, deposit paid — to have goods in the US for March 2027Consistent with the calendar rule: Q1 goods in the US or Europe need a confirmed order by the first week of December, earlier for glass

Market label notes the builder adds as context

  • United States — US labels print the fill in fluid ounces (fl oz = ml ÷ 29.5735), so a 30 ml bottle is 1.01 fl oz and 60 / 120 / 240 ml sizes exist alongside the metric steps; a domestic contact route for adverse-event reports goes on the label.
  • United Kingdom — the binary "Recycle / Do not recycle" mark was postponed from 1 April 2026 to 31 March 2027 for all materials, so a label run that must last beyond March 2027 should carry it now.
  • European Union — nominal content, Responsible Person details, INCI list and PAO must fit the pack; PPWR (Regulation (EU) 2025/40) has applied since 12 August 2026 and targets empty volume, recycled content and recyclability, so true internal capacity is measured against nominal size before a mould is committed.
  • Australia — the importer's name and address must appear on the pack, the line most often missed on artwork adapted from a domestic version.

These are packaging-side observations, not legal advice; your safety assessor and Responsible Person own the label.

Questions

Frequently asked

What should a cosmetic packaging spec sheet include?
Twelve lines: product type; fill volume (nominal, with brim-full held to ±5%); primary format; material; neck finish written as diameter/series (18/400, 20/410, 24/410 and so on); closure or pump with its dose (a treatment pump at 0.15–0.2 cc, a lotion pump at 2.0–3.5 cc, a fine-mist sprayer at 0.1–0.2 ml per shot); decoration process; colour reference; quantity per SKU and number of SKUs; target unit price; market and label needs; and launch date. A brief that carries all twelve lets a supplier quote per component with the route stated — stock, stock plus decoration, or private mould — instead of quoting a shape.
How do I choose packaging for a serum with vitamin C?
Vitamin C is oxygen-sensitive, so the structure must keep air and light off the bulk. The three answers that work are amber or opaque glass with a glass pipette dropper on an 18/400 or 20/400 neck, a PP/PETG airless bottle in 15–50 ml with a dose repeatable to about 0.05 ml, or a five-layer co-extruded EVOH tube whose oxygen transmission is roughly 0.2–1.2 against 150–300 for a single-layer PE tube. A clear PET bottle with a rubber-bulb dropper is the format most likely to turn a vitamin C serum brown on shelf. Whatever the format, run the actual bulk in the actual component at 48°C for 30 days before the golden sample is signed.
What MOQ should I expect for 3,000 units?
3,000 pieces per SKU clears most stock-plus-decoration routes and misses most custom ones. Through partner factories already tooled for small runs the indicative floors are about 500 for an undecorated stock bottle, jar, dropper or HDPE bottle, 2,000 for stock plus a screen-printed logo, about 1,000 for a frosted stock glass shape, 2,000–5,000 per shape for sprayed custom colour, 5,000–10,000 for tubes (3,000 sometimes negotiable) and for moulded-in colour, around 10,000 for airless bottles and electroplated closures, and 30,000 or more for made-to-order glass. The published industry floor is 5,000–10,000 per item, and minimums apply per component — a pump bottle is a bottle, a pump and an overcap with three minimums.
How long before launch should I order packaging from China?
Take the factory-gate cycle for your route — stock plastic 7–25 days, plus 5–7 for print, 30–40 for sprayed colour, 20–30 for stock airless, 15–20 for tubes, 30–60 for glass, 90–120 for a private mould — multiply it by 1.3, add 15 days if the order touches Chinese New Year (6 February 2027, 26 January 2028), then add sea freight of 18–25 days to the US West Coast, 30–40 to the US East Coast, 30–35 to the UK and Northern Europe or 20–25 to Australia, plus 5–10 days of clearance at each end. A screen-printed stock bottle for the US is therefore about 50–62 days door to door; sprayed glass for Europe is 115–125 days. For goods in the US or Europe before the end of March, sign the golden sample and pay the deposit by the first week of December.
Can I use PET for a formula with alcohol?
Below roughly 30% ethanol, yes — PET is the cheapest clear bottle for toners, micellar waters and essences. Above about 30% ethanol, no: PET swells, hazes and deforms, and a PET bottle approved for a high-alcohol serum has caused a full-line recall. Use glass or an alcohol-rated copolyester (PETG grade rated for alcohol), specify PTFE-coated or solvent-grade pump gaskets, write the ethanol resistance into the spec (for example ≥50%) and confirm it with a 48°C / 30-day immersion in the actual bulk. Perfume and nail products are glass only.
What tests does Vella run before shipping?
Four inspection gates on every order — IQC on incoming materials and pumps, IPQC on the line, FQC against the signed golden sample, OQC to agreed AQL before shipment — and a laboratory battery with published thresholds: vacuum leak at -0.08 MPa for 15 minutes with loss ≤0.5% (-0.06 MPa for standard bulks), decoration adhesion with 3M 600 tape over print and hot-stamp and 3M 810 over cross-hatched spray and plating, thermal cycling at 48°C and -15°C, drop from 76 cm to 1.5 m by format, pump and sprayer life ≥1,500 cycles with priming ≤5–10 strokes and output ≥95% aqueous / ≥90% non-aqueous, opening torque 0.2–0.7 N·m, formula compatibility with the actual bulk at 48°C for 30 days, colour at ΔE under D65 light, and heavy metals Pb+Cd+Hg+Cr(VI) ≤100 ppm by third-party laboratory. Vella is a sourcing partner working with vetted partner factories operating to ISO 22716 / GMP.
