The lifespan of rubber sealing strips for frameless doors is usually only 4-5 years. We carefully press the sealing strip at the edge of the roof to check for loss of elasticity and use a high-pressure water gun to wash the seams of the windows to check for direct water leakage due to aging.

Customs clearance at destination is usually handled by a licensed customs broker, not the exporter. You can hire one yourself or use a broker recommended by your shipping agent. The typical flow: your broker files the import declaration using the documents the exporter must provide — the commercial invoice, packing list, bill of lading, and the certificate of origin. Depending on your country's rules, you will also need to pay import duty, VAT or sales tax, and any excise or environmental levies before the car is released. Things that commonly delay clearance: mismatched VIN numbers between documents, missing pre-shipment inspection certificates (required in some African and Middle Eastern countries), or non-compliance with your country's used-car import age limits. Budget 3–10 working days for clearance after the vessel arrives, plus storage fees if documents are incomplete. Tip: send all documents to your broker for review before the ship departs China — fixing errors at origin is much cheaper than demurrage at destination.

We mainly collaborate with professional organizations certified by China's national CMA (Certification of Inspection and Testing Institutions). If you need the highest level of international endorsement, we can arrange for independent inspection agencies like SGS or TÜV to conduct Pre-Shipment Inspections (PSI) before loading at the port.
