Stainless steel tea infuser manufacturers

For food-contact safety and durability, you should prioritize Food-Grade 304 (18/8) or 316 stainless steel. These materials are highly resistant to corrosion and rust, ensuring that the tea's flavor remains untainted. Avoid '201' series stainless steel, as it is prone to rusting when exposed to acidic tea tannins over time.

The mesh density is critical for user experience. Ultra-fine mesh (laser-cut or high-density weave) is essential for preventing small tea particles (like Rooibos or tea dust) from escaping into the cup. Ensure the holes are small enough to filter debris but large enough to allow optimal water circulation for full flavor extraction.

Since these are food-contact items, they must comply with regional safety regulations. For the US market, FDA (Food and Drug Administration) certification is mandatory. For the EU, products must meet LFGB (Lebensmittel- und Futtermittelgesetzbuch) standards, which are often stricter regarding heavy metal leaching. Always request Migration Test Reports from the supplier.

Look for double-handle designs that fit various mug sizes, silicone-rimmed lids that double as drip trays to prevent mess, and foldable handles for compact storage. For premium branding, ensure the supplier offers laser-engraved logos and customized eco-friendly packaging.

Prioritize 'Audited Suppliers' who have undergone third-party verification by firms like SGS, Bureau Veritas, or TÜV Rheinland. Check their 'Audit Reports' to confirm their production capacity, quality control processes, and whether they are a direct manufacturer or a trading company.

The primary risk is surface scratching or denting during transit. Ensure the contract specifies individual polybags or bubble wrap for each unit and double-walled corrugated export cartons. For large sea freight orders, verify that the supplier uses desiccants to prevent moisture buildup and 'white rust' during long voyages.

Start by requesting a tiered pricing structure (e.g., 500, 1000, and 5000 units). If your initial volume is low, negotiate a higher unit price in exchange for a lower MOQ, with a written agreement that the price will drop once total annual volume hits a certain threshold. Always clarify if mold fees for custom shapes are one-time or refundable.

Use Secured Trading Services provided by Made-in-China.com to ensure your payment is held in escrow until shipping documents are verified. Never wire 100% of the payment upfront; a standard 30% deposit and 70% balance against the Bill of Lading (B/L) is the industry norm for protecting buyer interests.
