FAQ – 316L Stainless Steel Ring, 4mm Width, Polished Finish
Q1: What is the difference between 316L and 304 stainless steel for rings?
A: 316L contains molybdenum, which gives it superior corrosion resistance, especially against sweat and chemicals. It is also more hypoallergenic than 304, making it the preferred choice for body jewelry.
Q2: Can I order a sample before placing a bulk order?
A: Yes, sample rings are available at a nominal cost (deducted from your first bulk order). Please contact our sales team with your desired size and quantity.
Q3: How is the Mill Test Report provided?
A: The report (certifying chemical composition and mechanical properties per ASTM/EN standards) is included with each production batch. You may request a copy before shipment.
Q4: What is the minimum order quantity (MOQ) for wholesale?
A: Our standard MOQ is 100 pieces per size/style. For custom designs or private labeling, MOQ may be higher. We are flexible for trial orders.
Q5: Are the rings nickel-free?
A: 316L stainless steel is low-nickel and considered hypoallergenic. While trace amounts may exist, it is safe for most people with nickel sensitivities. The Mill Test Report details the exact composition.
Q6: Can I get different widths or finishes?
A: Yes, we offer custom widths (e.g., 2mm, 6mm, 8mm) and finishes (matte, brushed, black IP, gold PVD). Please inquire about options and lead times.
Q7: How long does shipping take?
A: For bulk orders, production takes 7–15 days after confirmation. Shipping time depends on destination (3–20 days via express, 15–35 days by sea). We ship from Shenzhen, Dongguan, or Guangzhou ports.
Q8: Do you provide private labeling or custom packaging?
A: Yes, we can emboss your logo on the ring interior and pack in custom-printed boxes. Contact us for a design consultation and pricing.
