Stainless steel bangles

For B2B sourcing, prioritize 316L Stainless Steel (Surgical Grade) over 304 grade. 316L contains molybdenum, which provides superior corrosion resistance and is hypoallergenic, making it ideal for jewelry that comes into prolonged contact with skin. Ensure the supplier provides a Material Analysis Report to verify the nickel release levels.

Avoid simple electroplating. Instead, specify PVD (Physical Vapor Deposition) Vacuum Plating. This technology provides a coating that is thicker and more wear-resistant, typically lasting 1-2 years under normal wear without fading. For premium lines, request 18K Gold PVD plating with a thickness of at least 0.03-0.05 microns.

Products must comply with REACH Regulation (EC) No 1907/2006 for the European market, specifically regarding Nickel, Lead, and Cadmium content. For the US market, ensure compliance with ASTM F2999 (Standard Consumer Safety Specification for Adult Jewelry) and California Prop 65. Always request SGS or Intertek test reports from the manufacturer.

Focus on the clasp mechanism and edge finishing. For hinged bangles, the tension of the spring should be tested for at least 5,000 cycles. Edges must be high-mirror polished to ensure there are no burrs that could scratch the wearer. Check for seamless welding at the joints to prevent breakage under pressure.

Implement a Pre-Shipment Inspection (PSI) strategy. Use a third-party inspector to randomly select samples from the bulk production and send them to a lab for chemical composition testing. Do not rely solely on the 'golden sample' provided during the negotiation phase, as material substitution is a common risk in high-volume manufacturing.

Stainless steel jewelry often has a high Minimum Order Quantity (MOQ) due to machine setup costs. Negotiate a mixed-style MOQ (e.g., 100 pieces total across 5 designs) to test market response. For pricing, use tiered volume discounts; typically, a 1,000-unit order should yield a 15-25% price reduction compared to a 100-unit order.

For jewelry, Air Express (DHL, FedEx, or UPS) is the standard due to the high value-to-weight ratio. Ensure the package is double-boxed and use tamper-evident tape. For large wholesale orders, consider Air Freight to a major hub to balance cost and speed. Always verify the HS Code (typically 7117.19) to calculate accurate import duties.

Utilize secure payment terms such as Trade Assurance or Letters of Credit (L/C) for large volumes. When sourcing through Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification by independent inspection companies like SGS, Bureau Veritas, or TÜV Rheinland to ensure the factory actually exists and has the stated production capacity.
