Roller forming equipment is large split-type complete industrial set, consisting of main machine frame, forming rolls, hydraulic system, electric control cabinet, material feeding & recoiling mechanism and other core components. It features large volume, heavy weight, vulnerable precision parts and easy-to-rust metal structures. During cross-border sea freight and long-distance land transportation, it faces multiple risks including bumping vibration, seawater moisture, salt spray corrosion, collision in loading & unloading, and temperature fluctuation. Combined with practical foreign trade export scenarios, this guide integrates standardized packaging procedures, container loading & fixing specifications, transportation control points and risk avoidance plans. It forms implementable export packaging and transportation summary, complying with customs clearance and cross-border logistics requirements of ports worldwide.

I. Pre-packaging Preparation of Equipment (Core Foundation for Operation)

Pre-packaging pretreatment is critical to avoid transportation rusting, malfunction and surface damage. All procedures must be completed in a dust-free and dry workshop. Packaging with dirt, water or debris is prohibited to adapt to high humidity and high salt environment of long-distance sea shipping.

1. Complete machine cleaning and impurity removal: Thoroughly clean iron scraps, oil stains and dust on the surface of machine frame, forming rolls and hydraulic pipelines. Blow narrow gaps with high-pressure air gun. Wipe working surfaces of precision forming rolls with dust-free soft cloth. Residues are forbidden to prevent transport abrasion and paint scratching.
2. Anti-rust & anti-corrosion treatment: Evenly spray special industrial anti-rust oil on all exposed machined metal surfaces, roll working faces, shaft necks, bolt joints and other precision parts.
3. Component splitting & classification: Modularly split equipment according to container size and load-bearing standard, divided into 5 categories: main large components, hydraulic accessories, electric control system and auxiliary parts. For frames with over-length or over-width that cannot fit into containers, customize separate transportation solutions. Mark numbers on all split components to match subsequent assembly sequence.
4. Protection pretreatment: For electric precision parts such as motors, sensors, servo drives and PLC electric control cabinets, block wiring ports and air vents in advance for sealed waterproof treatment, to avoid short circuit and component damage caused by moisture intrusion.

II. Graded & Classified Export Packaging Solutions (Differentiated Protection)

Abandon unified packaging mode. Implement graded packaging according to component value, precision and stress characteristics, balancing protection and logistics economy, meeting international export packaging standards and quarantine requirements.

1. Large Main Machine (Heavy Structural Parts) Full wooden box wrapping is not required. Adopt the mode of “anti-rust layer + waterproof film + steel structure reinforcement”. Wrap the whole machine with multi-layer PE waterproof film for full sealing to isolate moisture. Install rubber anti-collision corners to avoid bump damage during loading, unloading and stacking. Lifting holes are reserved at the bottom to adapt to mechanical loading & unloading.
2. Electric Control Cabinet, Hydraulic System & Servo Components (Electric Precision Parts) Adopt fully enclosed moisture-proof stretch film packaging. Cover all wiring ports and instrument panels with film to completely block seawater moisture and rainwater infiltration and prevent electric component failure due to dampness.
3. Accessories, Fasteners & Manuals (Loose Small Parts) Classify and pack small items such as screws, gaskets and spare parts with clear material labels and put them into special accessory boxes centrally. Equipment drawings, bilingual packing lists, certificate of origin and customs clearance documents shall be sealed separately and shipped together with goods to avoid loss of small parts or documents affecting customs clearance and later installation. Mark unified batch number for complete sets of equipment in the format of “Set 1/N” for convenient checking upon receipt.

III. Container Loading & Fixing Specifications (Anti-displacement & Anti-deformation)

Roller forming equipment has heavy dead weight, which is prone to displacement, tilting and collision under transport bumping. Loading and fixing is the core link of transportation safety. Follow the principle of “heavy at bottom, light on top, centered force bearing and multi-point fixing”.

1. Loading sequence: Prioritize hoisting large main machine components to the center of container bottom to ensure stable center of gravity. Then place medium-sized structural parts, and put accessory boxes on upper layer and vacant space. Heavy items are strictly prohibited to press precision components.
2. Loading reinforcement: Wedge and lock the gap between heavy equipment and container wall with solid wood blocks to eliminate shaking and displacement during transportation. Use steel wire ropes and tension belts for multi-point binding and tightening, and install anti-slip rubber pads to prevent sliding from bumping. Separate components with cardboard and wood blocks to avoid hard collision and friction.
3. Space sealing: After full loading, fill buffer materials into remaining gaps inside the container. Finally close container doors and apply seal locks. Record the whole loading process and keep video & photo files for logistics traceability and customer verification.

IV. Full-process Control of Cross-border Transportation (Multi-scenario Logistics Adaptation)

Combined with mainstream sea freight mode for roller forming equipment export, as well as short-distance land transport and multimodal transport, implement targeted full-process control to avoid common risks of cross-border logistics.

1. Logistics mode selection: Standard regular machines adopt full container sea freight with high cost performance and good protection. Over-length & over-width non-standard equipment adopts bulk carrier transport with reinforcement and customized lashing scheme. Small batches of accessories and precision small parts can be shipped by LCL (less than container load) with separate reinforcement and isolation.
2. Environmental risk prevention: For salt spray, high humidity and large temperature difference in ocean shipping, keep full sealed protection without unpacking, avoid open-air exposure and rain in transit. Require careful lifting during transshipment loading & unloading. Tilting, inversion and dragging of equipment are forbidden.
3. Document & insurance support: Prepare packing list, bill of lading, equipment manual and certificate of origin in advance to meet customs clearance requirements of Europe, America, Southeast Asia, Middle East and other regions. Purchase adequate all-risk cargo insurance covering damage, rust, loss and transport delay to safeguard export interests.
4. Full-track traceability: Track logistics status in real time. Pay close attention to loading/unloading and warehousing at transit ports. Synchronize logistics updates to customers timely to prevent customs clearance delay and damp storage.

V. Arrival Inspection & After-sales Review (Closed-loop Control)

到货验收与售后复盘（闭环管控） After equipment unloaded at destination port, cooperate with customers to complete inspection and review to form a complete closed loop of export transportation. First check equipment batch, quantity and component integrity, inspect outer package for breakage, water ingress and deformation. Verify precision parts, electric systems and metal structures one by one for rust and damage against packing list. If transport damage occurs, retain photo & video evidence immediately and start insurance claim procedure. Meanwhile record packaging and loading problems of this shipment, optimize subsequent export packaging scheme and continuously reduce transport damage rate.

VI. Core Practical Summary

The core of roller forming equipment export packaging and transportation lies in graded protection, precise fixing, full risk control and closed-loop inspection. Different from ordinary small goods, it is necessary to target the heavy and precision characteristics of equipment and abandon extensive packaging & transportation mode. Through pre anti-rust & moisture pretreatment, differentiated graded packaging, standardized loading reinforcement and cross-border full-process control, practical difficulties including sea freight rusting, loading/unloading damage, transport displacement and customs clearance obstruction can be effectively solved. It ensures high intact rate of equipment cross-border transportation, meeting international export standards and customer on-site installation requirements.
