When it comes to the supply chain and trade documents for materials like basalt, it typically involves several key documents that help in the procurement, transportation, and legal aspects of trade. Some of the most common documents involved are:

1. Purchase Orders (PO)

• Purpose: This is the formal agreement between the buyer and seller, specifying the amount, price, and other terms related to the basalt supply. This would be the starting point in the supply chain process.

2. Invoices

• Purpose: Issued by the seller to the buyer for the basalt materials supplied. This includes the price, quantity, and payment terms.

3. Bills of Lading (BOL)

• Purpose: A document used by a carrier to acknowledge receipt of goods for shipment. It provides evidence of the contract of carriage and can be used to transfer ownership of the basalt during transit.

4. Export/Import Licenses

• Purpose: Depending on the country, a license may be required for the export or import of basalt products, especially if they are in processed forms (like basalt fiber).

5. Certificates of Origin

• Purpose: This document certifies where the basalt material originates, which may affect duties or tariffs depending on the trade agreement between countries.

6. Packing Lists

• Purpose: A detailed document that accompanies the shipment, listing the exact contents of each package (size, weight, etc.) to ensure the buyer receives exactly what was ordered.

7. Customs Declarations

• Purpose: Required when the basalt is crossing international borders. It ensures that the shipment complies with the local customs regulations in both the importing and exporting countries.

8. Inspection Certificates

• Purpose: Sometimes, especially in international trade, the buyer may request an independent inspection or certification of the basalt’s quality and compliance with industry standards (e.g., ASTM standards for construction materials).

9. Shipping/Transport Documents

• Purpose: Various documents related to the transport of basalt. This could include truck transport forms, rail transport receipts, or maritime shipping documents depending on how the basalt is being moved.

10. Insurance Certificates

• Purpose: These are provided if the shipment is insured, giving both the buyer and the seller peace of mind that the goods are covered in case of damage or loss during transport.

11. Letter of Credit (LC)

• Purpose: A payment mechanism used in international trade where the buyer’s bank guarantees payment to the seller, once the terms in the letter of credit are met. This adds security for both parties.
