2oz glass bottle manufacturers

When sourcing 2oz (approx. 60ml) glass bottles, you must distinguish between Type I (Borosilicate), Type II (Treated Soda-Lime), and Type III (Soda-Lime) glass. For essential oils or chemicals, Amber glass is preferred as it filters out UV light to prevent product degradation. Ensure the glass is lead-free and BPA-free to meet food and cosmetic safety standards.

The most common neck finish for a 2oz bottle is 20-400 or 20-410. You must verify that the liner material (such as PE, PTFE, or Pressure Sensitive) is chemically compatible with your liquid. For pharmaceuticals or CBD products, prioritize Child-Resistant Closures (CRC) and Tamper-Evident rings to comply with safety regulations.

For the US market, bottles used for food or cosmetics must be FDA compliant. If shipping to Europe, ensure the materials meet REACH and RoHS requirements. For medical use, look for suppliers who can provide USP <660> (Glass Containers) or ISO 15378 certification, which ensures the manufacturer follows Good Manufacturing Practices (GMP).

B2B buyers can choose between silk-screen printing, hot stamping, or acid frosting. For high-end cosmetics, electroplating provides a metallic finish. Always request a pre-production sample to check the alignment and durability of the print, ensuring it does not peel when exposed to the bottle's contents.

Glass is fragile, so you should mandate 5-layer corrugated export cartons and individual cell dividers. For bulk orders, require palletization with plastic wrap and corner protectors. It is highly recommended to negotiate a breakage allowance (typically 1-3%) where the supplier replaces items broken during shipping if they exceed this threshold.

Focus on volume-based pricing tiers. A 2oz bottle is a high-volume commodity; increasing your order from 5,000 to 20,000 units can often reduce the unit price by 15-25%. Additionally, ask for free molds if your order exceeds a certain value, which saves significant upfront tooling costs for custom shapes.

Always check if the supplier is an Audited Supplier on Made-in-China.com. Review their Audit Report to see their actual production capacity and factory photos. Use Secured Trading Services to ensure your payment is only released to the supplier after you have confirmed receipt and quality of the goods.

Due to the high weight-to-value ratio of glass, Sea Freight (LCL or FCL) is the most economical choice. For 2oz bottles, which are relatively small, you can fit a large quantity in a 20GP container. Avoid air freight unless it is for urgent samples, as the shipping cost will likely exceed the product value.
