When exporting bathroom accessories like robe hooks to international markets, material selection is the foundation of product quality and customer satisfaction. Stainless steel has become the dominant material choice for bathroom hardware due to its corrosion resistance, durability, and aesthetic appeal. However, not all stainless steel is created equal.
The two most common grades for bathroom accessories are SUS 304 and SUS 316 stainless steel. Understanding the differences between these grades is crucial for Southeast Asian exporters targeting different market segments on Alibaba.com.
For most indoor residential bathroom applications, SUS 304 provides sufficient corrosion resistance at a lower cost. The cost difference between 304 and 316 stainless steel typically ranges from 20-30%, which can significantly impact pricing competitiveness on Alibaba.com's B2B marketplace.
