Bottle with infuser

You should prioritize BPA-free materials to ensure food safety. For plastic options, Tritan™ copolyester is the industry standard due to its high impact resistance, clarity, and heat resistance. If sourcing glass, ensure it is high-borosilicate glass, which withstands thermal shock. For metal components or stainless steel bottles, 304 (18/8) or 316 food-grade stainless steel is mandatory to prevent corrosion from acidic fruits.

Focus on the infuser basket density; a fine mesh is better for loose tea, while larger slots are suitable for fruit. The sealing mechanism must utilize food-grade silicone gaskets to ensure a 100% leak-proof experience. Additionally, evaluate the flip-top lid durability, looking for reinforced hinges and one-handed operation features which are highly valued in the fitness and travel markets.

For the US market, products must be FDA compliant and meet California Proposition 65 requirements regarding lead and phthalates. For the EU, LFGB (Lebensmittel- und Futtermittelgesetzbuch) certification is often stricter than standard EU food contact regulations and is highly recommended. Ensure the supplier provides valid test reports from accredited third-party labs like SGS, TUV, or Intertek.

Look for suppliers offering OEM/ODM services with low costs for logo printing (silk screen, laser engraving, or UV printing). The Minimum Order Quantity (MOQ) for custom colors usually ranges from 500 to 1,000 units. To optimize costs, consider bulk packaging (egg-crate style) instead of individual retail boxes if you plan to repackage locally, which can reduce shipping volume by 15-20%.

Always request a pre-production sample and a mass production sample. For large orders, hire a third-party inspection service to conduct a During Production Check (DUPRO) or a Final Random Inspection (FRI). On platforms like Made-in-China.com, prioritize Audited Suppliers who have undergone comprehensive on-site verification of their facilities and capabilities.

Use Secured Payment services provided by reputable B2B platforms to ensure your funds are only released after you confirm receipt of goods. Negotiate a 30/70 payment term (30% deposit, 70% balance against the Bill of Lading). Avoid using untraceable wire transfers to individual accounts; always pay to the company’s registered corporate bank account.

Since bottles are lightweight but high-volume, shipping costs are calculated by volumetric weight. To save costs, choose Sea Freight (LCL or FCL) for large volumes. Ensure the outer cartons have a double-wall corrugated structure and a bursting strength test rating to prevent crushing during transit. For glass bottles, specify drop-test compliant packaging (1-meter drop test).

Verify the HS Code (typically 3924.10 for plastic or 7013.37 for glass) to determine the exact import duties in your country. Be aware of anti-dumping duties that may apply to specific materials from certain regions. Consult with a licensed customs broker to ensure all documentation, including the Certificate of Origin, is accurately prepared to leverage any existing Free Trade Agreements (FTAs).
