All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

Our legal red line is that the amounts on the China Customs declaration, export license, commercial invoice, and bank receipt must be consistent across all four documents. We firmly refuse to engage in the illegal act of issuing "false low-value invoices" to assist buyers in evading customs duties in the destination country.

We are only responsible for delivering the goods to your designated transshipment port (such as Jebel Ali Port in Dubai). The warehousing fees, customs clearance fees, and storage fees for re-export within the free trade zone need to be calculated separately with local freight forwarders.
