Exporting stainless steel requires extreme care, as its surface finish, precision, and corrosion resistance are easily damaged during transportation.

I. Packaging - Protecting the Surface is of the utmost importance

1. Selecting Appropriate Packaging Materials:

Scratch Prevention: Use clean, impurity-free lining materials, such as:

Plastic Film: VCI (Vapor Corrosion Inhibitor), PE film, and stretch film. VCI film is particularly recommended as it releases rust inhibitors in confined spaces.

Rust-Proof Paper/Oil-Proof Paper: Used for wrapping between sheets or coils or on the surface.

Foam/Bubble Pads: Used to protect edges, corners, protrusions, or delicate components.

Felt/Non-Woven Fabric: Provides cushioning and scratch protection.

Do Not Use: Ordinary newspaper (ink contamination, acid corrosion), materials containing chloride ions (such as PVC film, which may cause pitting due to long-term contact), and materials that easily chip or become damp.

2. Sheets/Coils:

Layer Separation: Each sheet must be separated by a layer of rust-proof paper or plastic film to prevent scratches caused by sliding against each other. Edge Protection: Use sturdy plastic or metal corner protectors (L-shaped or U-shaped) to protect the four edges of the sheet and the outer ring of the coil, and secure the corner protectors with packing tape or wrap.

Waterproofing and Sealing: Tightly wrap and seal the entire material with waterproof canvas, thick plastic sheeting, or VCI film to prevent erosion by moisture, rain, and seawater. Pay particular attention to end seals for coils.

3. Pipes/Profiles/Rods:

Secure Strapping: Use steel strapping, plastic-steel strapping, or high-strength rope to secure the material neatly to prevent loosening and collision during transport. Padding (such as cardboard or rubber mats) should be added to the strapping points to prevent constriction.

End Protection: Protect the ends of pipes and profiles with plastic end caps or thick, impact-resistant materials.

Padding and Support: Use wooden planks, filler blocks, or other supports within the bundle or in the container's gaps to prevent shaking and deformation. 4. Equipment/Parts:

Custom Wooden Boxes/Wooden Racks: For precision equipment, valves, flanges, pump bodies, etc., sturdy fumigated wooden boxes (compliant with ISPM15 standards) or steel frame boxes are preferred.

Internal Securing: Products must be securely secured inside the box using foam, bubble wrap, wood blocks, and other fillers to prevent movement. Critical areas (such as flanges, threads, and polished surfaces) require additional protection (e.g., special sleeves or covers).

Moisture and Rust Prevention: A sufficient amount of desiccant (silica gel) should be placed inside the box. For products with high requirements, VCI anti-rust bags, rust inhibitors, or nitrogen gas may be considered.

5. Pallets and Reinforcement:

Sturdy Pallets: Use sturdy fumigated wooden pallets or plastic pallets that meet international transport standards.

Cargo Securing: Cargo must be tightly secured on the pallet with stretch film on all sides and secured with steel/plastic-steel strapping to prevent shifting or tipping.

Pallet Protection: Cargo on the pallet should not protrude excessively from the edge of the pallet. If necessary, add side panels or corner posts for added stability.

II. Marking and Shipping Marks - Clear and Unambiguous Instructions

1. Clear Labeling: Clearly and securely mark the outside of the package with:

Consignee and shipper information.

Contract number/order number, shipping mark.

Product name, material (e.g., 304, 316L), specifications, quantity, gross weight, net weight, and volume.

Country of Origin (Made in China).

2. Warning Labels: Crucial! Visible, internationally recognized warning labels must be affixed:

"Do Not Stack": Prevent deformation caused by heavy objects (especially sheet metal and pipes).

"Fragile": Reminds customers to handle with care.

"Keep Dry": Emphasizes moisture-proofing.

"This Side Up": For goods with specific orientation requirements.

"Use No Hooks": Prevents damage during lifting.

"Corrosion Resistant" / "Corrosive Resistant - Handle with Care": Emphasizes the special requirements for stainless steel.

Center of Gravity Marking (if necessary).

3. Barcode/QR Code: May be affixed if required or for internal tracking.

III. Transport Method Selection and Operation - Risk Mitigation

1. Method Selection:

Sea Freight: The most common and low-cost option, but also carries relatively high risks (humidity, salt spray, long shipping times, and multiple loading and unloading). Always choose containerized shipping (FCL or LCL), and absolutely avoid bulk cargo.

Air Freight: Fast, with minimal loading and unloading, and relatively good environmental control, it's suitable for high-value, precision, and urgently needed stainless steel products or small quantities. It also has high costs and size and weight restrictions.

Land Transport (International): Suitable for shipping to neighboring countries, but cross-border customs clearance and road conditions must be considered.

2. Container Requirements:

Clean and Dry: Always use clean, dry, and intact containers (free of holes, rust, oil stains, or odors). Inspect the container's floor, sides, and roof for foreign matter, water stains, and salt particles.

Container Type: Standard dry cargo containers are sufficient. Avoid using containers that have previously carried fertilizers, chemicals, or deliquescent or easily contaminated goods.

Moisture-Proofing Measures:

Lay dry wood planks or moisture-proof mats on the container floor.

Hang a sufficient amount of container-specific desiccant (strong moisture absorbent) inside the container.

Ensure that the cargo packaging itself is moisture-proof and sealed.

Loading and Securing:

Cargo must be stacked tightly and securely within the container, fully utilizing the space while avoiding gaps that could cause shifting. Use filler (empty pallets, wood blocks, air bags) to seal all gaps.

Allow adequate space between the cargo and the container walls (to facilitate air circulation), but ensure they are securely fastened.

Cylindrical cargo, such as pipes and coils, must be stored horizontally to prevent rolling and secured with stoppers.

Excessive height, width, and weight loading are strictly prohibited.

Consider using tie-down straps, brackets, or other similar methods to secure cargo to the container's tie-down points. 3. Loading and Unloading Operation Requirements:

Clear Instructions: Clearly emphasize to freight forwarders, shipping companies, and loading and unloading companies the special characteristics and handling requirements of stainless steel cargo (handle with care, avoid hooking, prohibit rolling, and prohibit rough stacking).

Use of Appropriate Equipment: Wide, undamaged slings, vacuum cups (for flatbeds), or clamps (specialized coil clamps) are required. Wire ropes and hooks that directly contact the cargo surface are strictly prohibited. Forklifts must be operated smoothly, and forks must be protected with protective covers.

Supervision: Supervision should be conducted at key loading and unloading points, if conditions permit.
