Modeling Rejection Rate Penalties
A rejected batch causes severe delays, but accepting a bad batch destroys your brand. This tool models the cost of reworking units, the cost of flying an inspector back for a second check, and the financial impact of the 2-to-4 week delay in getting your product to market.
Tips for China Importers
- Always inspect before shipment for orders over $3,000. A $350–450/day inspector fee is almost always cheaper than shipping defective goods and dealing with returns, chargebacks, and Amazon removal.
- Specify AQL levels in your purchase order. AQL 2.5 is standard for most consumer goods. Use AQL 1.0 for electronics, children's products, or anything safety-critical. No AQL spec = no standard.
- Write your product specs in Chinese. Most quality failures come from unclear specifications, not malicious intent. Translate your spec sheet — it costs $50–100 and prevents $5,000 rework orders.
- Build buffer days into your lead time. Even reliable factories hit delays. Add 7–14 days to any factory-quoted lead time, especially around Chinese New Year, Golden Week, and Labour Day holidays.
- Test your production sample, not just your pre-production sample. Factories sometimes pass pre-production samples and cut corners in mass production. Always test a random production-run unit before approving shipment.
