Export Packaging Specifications Guide for Refrigeration Equipment, Design for Moisture and Damage Prevention in Ocean Shipping

Refrigeration condensing units, air coolers, and condensers are precision metal equipment. During long-distance ocean shipping, they are exposed to high temperatures, humidity, salt spray, and rough handling. Inadequate packaging protection can lead to damage such as shell corrosion, fan deformation, and pipeline impact leaks, resulting in customer rejection and high repair costs. Based on years of practical experience in foreign trade shipments, a comprehensive standardized export packaging specification for refrigeration equipment has been developed.
1. Pre-treatment and Protection Steps Before Equipment Shipment
Before leaving the factory, the entire equipment undergoes purging and cleaning to remove dust from the fins, with sealing protective caps installed at pipe connections. Metal sheet metal parts are coated with anti-rust oil, while exposed copper pipes and fan bearings are wrapped for moisture and rust prevention. Desiccant is placed inside the electrical control box to prevent short circuits caused by high humidity during sea transportation. Fan blades are equipped with fixed clips to avoid deformation due to transport vibrations.
Without proper pre-treatment and direct packaging, metal components can corrode within two weeks in a marine salt spray environment, resulting in damaged equipment appearance and functionality upon arrival at the destination port.
II. Standards for Selecting Packaging Grades
R1: "Foam" must be translated as foam.  
Original text: Short-distance coastal, small-batch orders for neighboring countries: Thickened five-layer corrugated cartons, with internal foam corner protectors wrapped around edges.  

Translation:;
R1: "Foam" must be translated as "foam"  
For long-distance ocean shipments to the Middle East, Europe, America, and Latin America: Solid wood fumigated wooden crates / Fumigation-free plywood crates with thickened foam padding inside, reinforced with solid wood corner guards to prevent transportation impact;
Large complete machines and multi-head condensing units: Disassembled into independent wooden crates, with fixed bases to prevent internal sliding, and forklift bases added to the bottom of the crates for easy port loading and unloading.
3. Specialized Packaging Configuration for Moisture and Salt Spray Protection in Maritime Transport
The interior of the wooden box is fully lined with moisture-proof plastic film, and large-capacity desiccants are placed at the four corners of the box. The gaps of the wooden box are sealed with adhesive tape to minimize the intrusion of marine moisture and salt spray. Protective films are applied to the equipment nameplate and operation panel to prevent scratches during transportation. The packing list and inspection documents are stored inside the wooden box in sealed waterproof bags.
For coastal high-salt spray destination orders, anti-rust bags can be additionally placed inside wooden crates to further reduce the risk of metal corrosion.
IV. Standardization Requirements for Wooden Box Markings
On the exterior of the wooden crate, clear English markings are printed: equipment model, quantity, net weight and gross weight, moisture-proof, fragile, lifting instructions, and destination port information. This facilitates overseas port handling, customer warehouse inspection, and prevents damage from misplacement or inversion.
Shaoxing Xueying Refrigeration implements standardized ocean shipping packaging processes for all exported equipment, matching carton/wooden crate protection solutions based on maritime transit duration to the destination. Complete pre-treatment for rust and moisture resistance is conducted for entire units, while large-sized units are reinforced with solid wood bases to effectively prevent damage from collisions and corrosion during long-distance shipping. The company can customize external packaging logos and brand identifiers according to client requirements, meeting OEM brand labeling needs for foreign trade orders.
V. Key Points for Packing and Shipment Verification
Take complete photos of the equipment's appearance before packing; verify that accessories, manuals, and inspection documents are complete before sealing the box; ensure the wooden crate is securely fixed with no gaps or晃动;熏蒸木箱 must include熏蒸 certificates to meet各国海关检疫要求.
summary
For ocean shipping refrigeration equipment packaging, it is essential to implement comprehensive rust prevention pre-treatment for the entire unit, reinforce external packaging in grades, apply specialized moisture-proof and salt spray protection, and ensure standardized labeling. A well-established packaging process can significantly reduce the likelihood of cross-border transportation damage, minimize overseas arrival malfunctions and post-sales disputes, and maintain the brand's international reputation.
