PET Cosmetic Bottle Wholesale: Buyer’s Guide to Sizes, Necks & MOQ

Choosing the right PET cosmetic bottle is the difference between a packaging program that ships on time and one that stalls in tooling, filling, or compliance. This guide walks brand owners and procurement teams through the sizes, neck finishes, materials, and MOQ realities of buying PET cosmetic bottles wholesale from a manufacturer like Shijin.

Bottles from our catalogue — PET cosmetic bottles across the size range.

Why PET Leads Cosmetic Packaging

PET (polyethylene terephthalate) is the default for cosmetic bottles because of its clarity — up to 95% light transmission — and its strong barrier against water and oxygen. For face serums, toners, lotions, and cleansing oils, PET keeps the formula stable while showing the product through a premium, glass-like wall. It is also roughly one-third the weight of glass, which lowers freight cost and breakage on export lanes to the US, EU, and Australia.

Common Cosmetic Bottle Sizes

Shijin’s stock and custom PET cosmetic bottles span 15 ml to 500 ml. The most requested wholesale sizes are:

30–60 ml — essence water, eye cream, travel kits (40 ml PET essence bottle, 60 ml foam bottle)
100–120 ml — facial toner, serum (100 ml toner bottle, 120 ml OEM bottle)
150 ml — the workhorse size for lotion and serum (150 ml custom bottle, 150 ml wholesale)
177–340 ml — cleansing oil, body emulsion (177 ml cleansing oil bottle, 340 ml custom bottle)

Neck Finish: The Part That Actually Matters

The neck finish decides which cap, pump, or sprayer fits. The two most common cosmetic closures are 24/410 and 28/410. A 24/410 neck pairs with treatment pumps, disc-tops, and screw caps; 28/410 is typical for lotion pumps and wider dispensing. Always confirm neck size before committing to a closure, because a mismatched neck means a delayed fill line.

Size	Typical use	Common neck
30–60 ml	essence, eye care, travel	24/410
100–150 ml	toner, serum, lotion	24/410
177–340 ml	cleansing oil, body	24/410 or 28/410

MOQ, Sampling & Customization

Wholesale custom PET bottles start at 5,000 pieces in standard colors. With in-house tooling, Shijin turns prototypes in 3–10 days, so you can validate a shape before a full run. Decoration is done in-house: silk-screen up to 6 colors, hot stamping, labeling, spray coating, frosting, and soft-touch. Private mold tooling is available with SJ identifiers exclusive to your brand.

Compliance note: Shijin is ISO 9001:2015 certified and supplies the compliance documents your market requires — including FDA and EU 10/2011 certificates on request — so your order clears customs and retailer audits.

What cosmetic formulas demand from the bottle

For cosmetic fills the bottle is part of the compliance and performance chain, not just a container. The body has to hold the formula without stress cracking or leaching, survive the filling line, and stay readable after months on a shelf or in a warehouse.

Across our 30+ blow-molding lines we see the same non-negotiables: a neck that seats the closure squarely, wall thickness tuned to the fill weight, and colour and decoration that survive transport and UV. A bottle that passes the bench test but fails the warehouse is not a pass.

If the formula is viscous, acidic or solvent-based, tell us at the enquiry stage. The resin choice and the lining of the closure both shift, and selecting them early is far cheaper than re-tooling after a failed stability test.

Capacities we stock for cosmetic

Model	Material	Capacity	Neck
SJT0227	PET	227 ml	32 mm
Custom 400ml HDPE Bath & Body Bott	HDPE	400 ml	28/410
SJE1645	PE	630 ml	Custom
SJT0086	PET	86 ml	32 mm

These are stock shapes from our catalogue — the same tools a buyer samples first before committing to a custom mold. Capacities run from small trial sizes to bulk drums, so most cosmetic programmes can start from an existing mold and skip tooling lead time.

Sampling from a stock mold also de-risks the launch: you get a real, fill-tested bottle in days, validate it on your line, then scale or customise once the volume is proven.

Compliance and documentation

Every food-contact and pharma-adjacent bottle we make is produced under ISO 9001 controls, with FDA, SGS and EU 10/2011 food-contact documentation available on request. For export we supply the material certificate and, where required, UN-marked HDPE options for chemical transport.

If your market needs a specific claim (BPA-free, documented recycled content, tamper-evident), tell us at the sampling stage so we select the right resin and closure before the first run.

Sampling and first-run support

Because the tool is cut in-house, sampling lead time is typically 3–10 days from drawing to first article. We hold the first-article sample against the drawing, confirm wall and weight, and only then move to bulk.

For a new programme that means you can prove the bottle on your filling line before committing to a large order — and repeats stay consistent because the same mold and resin are used on every run.

Where most buyers start

Most buyers do not need a custom mold on day one. Start from a stock shape in the right material and capacity, validate it on your line, then customise once the volume justifies the tool.

If you send us the formula, the fill volume and the closure you have in mind, we can usually point to a stock mold within a day and have a sample in your hands within the week.

Frequently Asked Questions

What is the minimum order quantity for custom PET cosmetic bottles?

Standard custom orders start at 5,000 pieces in white, black, or natural. Custom colors and electroplated finishes start at 10,000 pieces. In-stock shapes can often ship at lower MOQs.

How long does sampling take?

With in-house tooling, prototypes are ready in 3–10 days after your brief is confirmed. Existing molds can ship samples even faster.

Can I print my logo on the bottle?

Yes. In-house decoration includes silk-screen printing up to 6 colors, hot stamping in gold or silver, pressure-sensitive labels, spray coating, frosting, and soft-touch finishes.
