Stainless steel shaker

B2B buyers should prioritize Food-Grade Stainless Steel, specifically 304 (18/8) or 316 grade, to ensure corrosion resistance and durability. Avoid 201 grade for long-term use as it is prone to rusting. Ensure the material thickness is at least 0.5mm to 0.7mm to prevent denting and provide a premium hand-feel. For weighted shakers (Boston style), verify that the weighted caps are securely welded to maintain balance during high-speed agitation.

Since shakers come into contact with beverages, they must meet strict food safety regulations. For the US market, ensure FDA (Food and Drug Administration) compliance. For the EU, products must adhere to LFGB (Lebensmittel- und Futtermittelgesetzbuch) standards and REACH regulations regarding chemical substances. Always request BPA-free certification for any plastic or silicone components, such as gaskets or strainers.

Common finishes include Mirror Polishing, Brushed/Satin Finish, PVD Plating (Gold, Rose Gold, Black), and Powder Coating. While PVD plating offers a luxury aesthetic, it increases the cost by 15-25% and requires specific care instructions (usually hand-wash only). Mirror polishing is the most cost-effective and durable for high-volume commercial use. Ensure the supplier uses electroplating or high-temperature baking to prevent peeling or fading over time.

For Cobbler shakers, the tapered fit between the cap, strainer, and tin must be precision-engineered to create a vacuum seal when chilled. For Boston shakers, the rim diameter must allow for a tight friction seal. Request samples to test the thermal contraction seal; a high-quality shaker should not leak even when shaking thin liquids with ice for over 20 seconds.

Implement a Pre-Shipment Inspection (PSI) through a third-party agency. Focus on surface scratch checks, leak tests, and salt spray tests (to verify rust resistance). For large orders, use Trade Assurance services on platforms like Made-in-China.com to ensure payment security and quality recourse. Never release the final 70% balance payment until the inspection report is approved.

Negotiate based on Raw Material Indexing; since stainless steel prices fluctuate, locking in a price based on current market rates for 304 steel can prevent sudden surcharges. Ask for tiered pricing (e.g., 500, 2000, and 5000 units) and request free laser-engraved branding for orders exceeding 1,000 units. If you are a repeat buyer, negotiate for Net-30 payment terms after the third successful transaction.

Stainless steel is prone to scratching during transit. Insist on individual bubble wrap or PE bag packaging for each component, placed inside a double-walled corrugated master carton. For sea freight, ensure the use of desiccant silica gel packs inside the cartons to prevent moisture buildup and 'white rust' or oxidation during long-haul ocean transit.

Verify the HS Code (typically 7323.93 for stainless steel table/kitchenware) to determine the exact tariff rate in your country. Be aware of anti-dumping duties that some regions (like the EU or USA) may impose on specific steel products from certain origins. Work with a freight forwarder experienced in DDP (Delivered Duty Paid) terms if you want to avoid the complexity of local customs clearance.
