Core Product Specifications

Specification note: exact bottle height, diameter, neck finish, brimful capacity, glass distribution, wall thickness, empty weight and pipette length vary by capacity and selected mold. Request the capacity-specific technical drawing and physical sample before approving artwork or filling equipment. The marketplace figures “21 × 14 × 11cm” and “2.0kg” appear to be shipping-package data and should not be treated as the size or weight of one bottle.

Capacity Guide

Product Features and Buyer Benefits

• Modern flat shoulder: the clean transition from neck to body gives the bottle a more architectural appearance than a conventional rounded shoulder.
• Coordinated size family: four capacities help brands build trial, targeted-treatment and full-size product ranges.
• Controlled application: a matched pipette allows users to dispense low-viscosity formulas more carefully than an open-mouth bottle.
• Flexible branding: broad cylindrical surfaces support frosting, color coating and direct logo printing.
• Multiple closure options: the same bottle family may be paired with a dropper, treatment pump, mist sprayer or screw cap when neck compatibility is verified.

Glass Compared with Other Packaging Materials

Glass is a strong starting material for oils and serums, but it does not make the complete package universally compatible. The dropper bulb, gasket, collar, thread and pipette must also tolerate the actual formula. Essential oils and active serums should always be tested in the final assembled package.

Clear, Frosted or Amber: Which Finish Should You Choose?

Clear glass

Clear glass displays the formula’s natural color and works well for minimalist or laboratory-inspired branding. It provides little meaningful light screening, so light-sensitive products may need a carton or a different bottle color.

Frosted clear glass

Frosting creates a soft, premium surface and partially diffuses the view of the product. Frosting is primarily an aesthetic treatment; it should not be described as guaranteed UV protection.

Amber glass

Amber glass screens more light than clear glass and suits apothecary, botanical and essential-oil positioning. The actual protection still depends on glass color density, wavelength, formula sensitivity and secondary packaging.

Logo, Color and Closure Customization

Boyu Packaging can coordinate bottle spraying, frosting, silk-screen printing and custom logo placement. Provide editable vector artwork, print dimensions, Pantone colors and a physical color reference when accuracy is critical. A decorated sample should be approved before mass production.

Dropper structure

A typical dropper combines a rubber or elastomer bulb, plastic threaded insert, decorative collar, gasket and glass pipette. Although some marketplace attributes list the collar as glass, the visible dropper collar is normally plastic or metal. Request a complete component breakdown for the selected version.

Alternative closures

A treatment pump can suit lighter lotions or controlled-dose serums, while a fine-mist sprayer may suit watery hair or face products. A screw cap can be used for storage or with an appropriate reducer. Each closure must match the bottle neck, gasket requirements and formula viscosity; closures are not interchangeable solely because they look similar.

Manufacturing and Decoration Process

1. Select the capacity, existing bottle mold, neck finish and closure.
2. Form and anneal the glass bottle to reduce internal stress.
3. Inspect the neck, shoulder, body, base and visible glass defects.
4. Apply frosting, spraying, silk-screen printing or other approved decoration.
5. Match the pipette length, bulb, gasket and collar to the bottle.
6. Approve the decorated and functional sample before mass production.
7. Complete final inspection, protective packing, palletizing and shipment.

Quality Control and Leak Prevention

A reliable dropper package depends on the interaction of the bottle neck, cap thread, sealing surface, gasket, bulb and pipette. Leak resistance cannot be judged from the bottle alone.

• Inspect cracks, chips, deformation, stones, unstable bases and visible defects against an agreed limit sample.
• Measure bottle height, diameter, neck dimensions, capacity and closure fit.
• Confirm pipette length, bulb recovery, product uptake and dispensing performance.
• Check application torque and conduct side-position or inverted leak tests using a suitable test liquid.
• Verify coating color, frosting consistency, print position, adhesion and abrasion resistance.
• Use partitions, cartons and pallets to reduce glass-to-glass contact during handling and export.

Before filling bulk quantities, test the final formula in production-representative samples at normal and elevated temperatures. Monitor leakage, evaporation, discoloration, odor transfer, gasket damage, bulb swelling or hardening, pipette blockage and decoration changes. Long-term compatibility approval remains the responsibility of the brand or filler.

Suitable Formulas and Use Cases

After compatibility testing, this bottle can be used for facial serums, facial oils, essential-oil blends, beard oil, cuticle oil, hair and scalp oil, liquid botanical extracts, eye treatments and other low-viscosity cosmetic products. Typical customers include skincare brands, hair-care companies, spas, salons, aromatherapy businesses, private-label importers, contract fillers and wholesale distributors.

It may not be the right dispenser for thick lotions, gels or formulas containing particles. A viscous serum may fill the pipette slowly, while particles can obstruct the opening. If the product is thick, compare the dropper with a treatment pump using actual filled samples.

Safety, Sustainability and Reuse

Glass is chemically stable for many cosmetic formulations and can be recycled in regions with appropriate collection systems. The bottle may also be reusable, but the dropper assembly combines several materials and may need to be separated before recycling.

For refill programs, brands should provide a validated cleaning and handling method. Repeated consumer refilling is not automatically safe for water-based products because residual formula and moisture may create a contamination risk. Environmental claims should consider the full package, decoration, protective cartons and shipping weight rather than glass alone.

MOQ, Samples and Pricing

The regular MOQ for a customized order is normally 10,000 pieces per design. Some existing plain bottles may be available for samples or limited trial quantities, but availability must be confirmed. Non-stock glass colors, special closures and customized decoration may require 5,000–30,000 pieces depending on the supplier and process. The “MOQ 100” marketplace field should not be interpreted as a guaranteed MOQ for fully customized production.

Price depends on capacity, bottle weight, glass or coating color, dropper components, number of print colors, decoration coverage, inspection standard, assembly and export packing. For a comparable quotation, provide quantities by capacity, destination port or country, artwork, bottle finish, dropper specification and preferred Incoterm.

OEM/ODM Ordering Process

1. Project brief: confirm formula type, capacity, quantity, destination, finish and closure.
2. Component selection: choose the bottle mold, neck, dropper, pipette and optional secondary packaging.
3. Quotation: review unit price, sample charges, tooling, payment terms, packing and Incoterm.
4. Artwork: approve the print area, logo position, Pantone reference and finish specification.
5. Sampling: assess appearance, closure fit, formula compatibility and filling-line suitability.
6. Production: proceed after the approved sample, artwork and deposit are confirmed.
7. Inspection and shipment: complete agreed QC, packing documents, palletizing and dispatch.

Is a new mold required?

No new bottle mold is usually needed when an existing 10ml, 15ml, 20ml or 30ml format meets the project. A proprietary shape, embossed logo, special base, custom capacity or non-standard neck may require new glass tooling. A unique cap or closure can require separate tooling. Mold cost, ownership, maintenance and sampling rounds should be agreed in writing.

Production lead time

Plain stocked items may be prepared in approximately 7 days after order confirmation. Customized or non-stock orders typically require about 15–45 days after the sample, artwork, deposit and all components are approved. New tooling, complex decoration, special closures, repeated revisions or peak production periods may extend the schedule.

Shipping and First-Time Importer Checklist

• Request pieces per carton, carton dimensions, gross/net weight, pallet count and total CBM before booking freight.
• Confirm whether bottles and droppers will be assembled or packed separately.
• Approve protective partitions and pallet requirements for fragile glass.
• Use cargo insurance where appropriate and document carton condition at receipt.
• Check HS classification, duties, labeling rules and local packaging obligations with a qualified customs adviser.
• Build sampling, compatibility testing, production, transit and customs clearance into the launch schedule.

What Importers Usually Want to Know

Searches such as “30ml frosted serum dropper bottle manufacturer,” “amber glass bottle for hair oil wholesale” and “custom flat shoulder dropper bottle MOQ” show strong commercial intent. Professional buyers want more than a product image: they need verified drawings, bottle weight, neck finish, pipette length, formula compatibility, decoration limits, leak-test methods, sample timing, replacement terms and landed cost. Confirming these details early reduces sampling rounds and prevents expensive component mismatches.

Frequently Asked Questions

Is the MOQ really 100 pieces?

Not for a normal fully customized production order. A quantity of 100 may refer to a marketplace trial offer or limited plain stock. Regular customized orders are normally quoted from 10,000 pieces per design, subject to capacity and decoration.

Can different capacities be combined to reach the MOQ?

Do not assume they can be combined. Different capacities use different bottle molds and pipette lengths, and MOQs may apply separately to each size, color and printed design. Submit the required quantity breakdown for confirmation.

Is amber glass better for essential oils?

Amber glass generally screens more light than clear glass and is often preferred for light-sensitive oils. It does not replace formula stability, compatibility and shelf-life testing.

Is the dropper leak-proof?

The matched dropper is designed for leak-resistant use, but performance depends on the neck, gasket, application torque, formula and shipping conditions. Approve filled-product leak and aging tests before launch.

Can the bottle hold lotion?

The bottle may hold some light lotions, but a dropper is generally intended for low-viscosity liquids. Test the actual formula with a treatment pump if dispensing through a pipette is slow or inconsistent.

Can Boyu Packaging provide custom labels or boxes?

Yes. Labels, printed cartons and other secondary packaging can be coordinated as part of an OEM project, subject to their own MOQs, artwork and lead times.

How are quality claims handled?

Boyu Packaging reviews documented shortages, breakage, decoration defects or functional problems against the approved sample and purchase specification. Retain affected goods and provide batch, carton, photo, video and inspection evidence promptly. The remedy is assessed according to the confirmed contract and defect responsibility.
