Baby bottle

You should prioritize BPA-free materials. The most common options are Polypropylene (PP), which is lightweight and break-resistant, Borosilicate Glass, which offers superior thermal shock resistance and chemical purity, and Food-grade Silicone, known for its soft texture and heat resistance. Ensure the nipples are made of medical-grade silicone to prevent allergic reactions and ensure a natural latch.

For the US market, compliance with FDA (Food and Drug Administration) regulations and CPSIA (Consumer Product Safety Improvement Act) is mandatory. For the EU, products must meet EN 14350, which specifies safety requirements for drinking equipment. Always request Migration Test Reports to ensure no heavy metals or harmful chemicals leach into the milk.

Look for anti-colic venting systems that reduce air ingestion, which is a high-demand feature for parents. Additionally, ergonomic shapes for easy gripping and wide-neck designs for easier cleaning and filling are significant selling points. Accurate, permanent volume graduations (in both ml and oz) that do not fade after repeated sterilization are essential for quality perception.

Confirm that the bottles can withstand temperatures of at least 120°C (248°F) for plastic and higher for glass. They must be compatible with steam sterilization, boiling water, and UV sterilizers. Ask the supplier for thermal shock test results, especially for glass bottles, to ensure they won't crack when moving from a refrigerator to a bottle warmer.

Always request pre-production samples and conduct third-party lab testing before the final shipment. Since baby products are high-risk categories, you should utilize Made-in-China.com's Secured Trading services to ensure payment is only released after the goods pass inspection. Verify if the supplier has an ISO 13485 (Medical Devices) or ISO 9001 certification to ensure consistent manufacturing quality.

Baby bottles, especially glass ones, are fragile. Ensure the supplier uses five-layer corrugated export cartons and individual bubble wrapping or egg-crate internal dividers. For sea freight, request palletization to minimize manual handling. Ensure the HS Code (typically 392410 for plastic or 701337 for glass) is correctly declared to avoid customs delays and ensure correct duty application.

For private labeling (OEM), suppliers usually require an MOQ of 2,000 to 5,000 units. Negotiate a staged deposit (e.g., 30/70) where the final 70% is paid only after a Passed Inspection Report. If you are a startup, look for suppliers on Made-in-China.com that offer 'Ready-to-Ship' products with lower MOQs to test the market before committing to custom molds.

Ensure the bottle design does not infringe on existing patents from major brands (like Philips Avent or Dr. Brown's). Ask the supplier to provide a Letter of Authorization if they are using a patented venting technology. When creating your own design, sign a Non-Disclosure Agreement (NDA) and a Non-Compete Agreement before sharing technical drawings.
