We communicate with customers about product specifications, order quantities, packaging requirements and export arrangements. Before shipment, our team can review the agreed product details and coordinate the relevant documentation and inspection requirements.

 

 

Packaging should protect the FeSi75 lumps during handling, storage and international transportation. For bulk export orders, the packaging arrangement should be confirmed according to the shipment quantity, destination and customer's unloading requirements.

1. Standard 1 MT Jumbo Bags

Our standard packaging option is a 1 MT jumbo bag. The actual bag specification, lifting arrangement and package construction should be confirmed before production and packing.

For customers with different warehouse or transportation requirements, customized packaging can also be discussed.

2. Customized Packaging Requirements

Before confirming the packaging arrangement, buyers should specify:

• Required net weight per bag.
• Number of bags and total shipment quantity.
• Jumbo bag or other agreed packaging type.
• Required lifting and unloading arrangements.
• Bag marking and shipping mark requirements.
• Any special packaging instructions for the destination market.

3. Bag Marking and Batch Identification

For export shipments, clear package identification helps buyers organize receiving, warehouse storage and batch traceability.

Where required by the purchase order, package markings can include:

• Product name: Ferro Silicon 75.
• Grade: FeSi75.
• Nominal particle size: 5–10cm (50–100mm).
• Net weight per bag.
• Batch or lot identification.
• Shipping marks and destination information.

The actual marking format should be confirmed with the buyer before packing.

 

 

For FeSi75 lump orders, chemical composition and physical size are two separate quality requirements. A shipment may meet the agreed silicon content but still require additional size inspection before dispatch.

For orders requiring controlled particle-size distribution, screening and size inspection can be confirmed as part of the production and shipment requirements.

1. Chemical Composition Verification

The chemical composition should be checked against the limits confirmed in the purchase order. Important elements may include:

• Silicon (Si): minimum required silicon content.
• Aluminum (Al): agreed maximum aluminum content.
• Calcium (Ca): maximum limit where specified.
• Carbon (C): agreed carbon restriction.
• Phosphorus (P) and Sulfur (S): controlled impurity limits.

Actual batch results should be documented in the corresponding Certificate of Analysis (COA).

2. Particle-Size Screening

The nominal 5–10cm specification corresponds to 50–100mm. If the order requires size screening, the inspection criteria should be agreed before production or shipment.

For size-controlled orders, the buyer can confirm:

• Nominal size range: 50–100mm.
• Acceptable undersize percentage.
• Acceptable oversize percentage.
• Maximum permitted fines content.
• Sampling and inspection requirements.

These limits should be stated numerically in the purchase specification instead of relying only on the general description of 5–10cm lumps.

For a more detailed explanation of particle-size requirements, see our Ferrosilicon Particle Size Specification Guide.

3. Visual Condition Inspection

Before packing, the material can be checked for visible contamination, excessive powdering and foreign materials according to the agreed inspection scope.

Repeated dropping and rough handling should be minimized during processing and loading because they may break larger lumps into smaller pieces and increase fines.

4. Packing and Weight Inspection

Before dispatch, the packing inspection can include:

• Bag condition and packaging integrity.
• Net weight per bag.
• Total number of packages.
• Package identification and batch markings.
• Consistency between packing records and the purchase order.

Where third-party inspection is required, the inspection scope and acceptance criteria should be agreed before shipment.

For chemical verification, read our Ferrosilicon 75 COA Verification Guide.

 

 

Container loading is an important part of the export process. For jumbo-bag FeSi75 shipments, the loading arrangement should be coordinated according to package dimensions, total cargo weight, container payload and the customer's unloading arrangements.

The following checkpoints can be used when preparing a shipment.

Step 1: Confirm the Loading Plan

Confirm the order quantity, bag capacity, number of packages and selected trade terms before arranging the shipment. The actual loading quantity must comply with the container's rated payload and applicable transportation requirements.

Step 2: Check Container Condition

Before loading, inspect the container for visible damage, water ingress, excessive moisture, contamination and other conditions that could affect the cargo.

FeSi75 should be kept dry during storage and transportation. A suitable dry container and appropriate packaging help reduce the risk of moisture exposure.

Step 3: Verify Package Quantity and Markings

Check the package count, bag identification and recorded net weight against the loading plan. Any differences should be resolved before the container is sealed.

Step 4: Load and Secure the Cargo

Jumbo bags should be positioned and secured according to the loading plan and applicable cargo-handling requirements. Repeated dropping and rough handling should be avoided to minimize lump breakage and the formation of fines.

Step 5: Record Loading Information

Where required, loading records and photographs can be prepared to document:

• Container identification.
• Visible container condition before loading.
• Package quantity and bag markings.
• Loading arrangement.
• Final cargo condition before container closure.

Loading photographs can be included in the agreed shipment documentation package.

Proper storage and handling help maintain the physical condition of Ferro Silicon 75 lumps before they reach the customer's facility.

Keep the Material Dry

Store FeSi75 in a dry environment and protect the packages from rain and water exposure during transportation. Moisture protection should be maintained throughout warehouse storage and shipment.

Minimize Mechanical Damage

Repeated dropping, rough unloading and unnecessary movement can break larger lumps into smaller pieces. Appropriate lifting and handling practices help maintain the agreed particle-size distribution and reduce additional fines.

Maintain Batch Identification

Keep package markings and batch records consistent with the corresponding COA and packing list. This helps buyers identify the material during receiving, storage and subsequent production use.
