A curated set of free tools designed for premium product buyers, resellers and collectors who use Chinese agents. Estimate shipping costs, convert product links, understand sizing, plan for customs and even find products using AI image recognition.
ChinaBuyHub Tools is a premium utility suite built specifically for buyers using Chinese shopping agents to order premium and fashion products. Instead of generic calculators, each tool is tailored for real agent workflows: shipping cost patterns, consolidation strategies, customs thresholds and multi-agent link conversion.
