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.

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.

If your market is in extremely cold regions (like Russia or Northern Europe), we strongly recommend purchasing ternary lithium (NMC) models equipped with heat pump air conditioning. The range achievement rate of used LFP batteries typically plummets at minus 15 degrees, and we will alert you accordingly.
