Packaging and Shipping

Packaging

• Preforms are packed in sturdy cartons with protective inner layers to avoid scratches and deformation during transit. Each carton is marked with product model, quantity and shipping information for easy warehouse management.
• Shipping Cost & Tariff Benefits of Bottle Preform Shipment
• Shipping bottle preforms instead of finished bottles brings obvious economic advantages for importers:
• Space saving: Preforms take much less container space compared with finished hollow bottles. More goods can be loaded per container, reducing unit freight cost.
• Lower import tariff: In many countries, bottle preforms enjoy more favorable tariff rates than finished plastic bottles. It helps importers cut customs duty expenditure significantly.
• Reduced damage risk: Compact preform shape is less prone to breakage and collision damage during long‑distance sea or air transport.
• Flexible local production: Buyers can blow‑mold preforms into finished bottles at local factories, realizing on‑demand production and cutting finished‑goods inventory pressure.
