About freight forms
These forms are typically utilized by logistics managers, warehouse supervisors, and business owners who manage the daily complexities of outbound and inbound freight. Whether you are shipping via air or ground, specific documents such as a Bill of Lading or a Shipper’s Letter of Instruction (SLI) are required to define the contract of carriage and provide necessary export data. These documents ensure that hazardous materials are handled safely, tariffs are applied correctly, and that carriers have the specific instructions needed to report shipments to regulatory bodies.
Managing this paperwork manually can be a significant administrative burden that is prone to human error. Tools like Instafill.ai use AI to fill these complex freight forms in under 30 seconds, ensuring data accuracy and security while allowing logistics professionals to focus on operations rather than repetitive data entry.

How to Choose the Right Form
Selecting the correct freight documentation is essential for ensuring your cargo moves through the supply chain without delays, billing errors, or compliance issues. The choice primarily depends on your chosen carrier and the mode of transportation (air versus ground).
For Air Freight and International Export
If you are coordinating an international shipment or using air transport via UPS, the UPS Supply Chain Solutions Shipper’s Letter of Instruction / Air Waybill (Air Freight Services) is the appropriate choice. This form functions as a comprehensive instruction set for the carrier. Use this form when:
- Customs Filing is Required: You need to provide export-control data such as Schedule B/HTS, ECCN, or EAR99 details.
- Power of Attorney: You are authorizing UPS to file Electronic Export Information (EEI) in the Automated Export System (AES) on your behalf.
- Detailed Routing: Your shipment requires specific service level designations and insurance declarations for high-value air cargo.
For Domestic Ground and LTL Shipping
When moving freight via truck within North America using FedEx, you should use the FedEx Freight Uniform Straight Bill of Lading (Original—Not Negotiable). This is a standard contract of carriage for Less-Than-Truckload (LTL) shipments. Choose this form for:
- Standard Rating: You need to specify the NMFC class, weight, and freight description to ensure accurate billing.
- Hazardous Materials: You are transporting regulated materials that require official certification and emergency contact information.
- Standard Logistics: You need to define billing terms (Prepaid vs. Collect) or specify C.O.D. (Cash on Delivery) requirements.
Quick Selection Tips
- Check the Carrier: These forms are carrier-specific. Use the UPS form for UPS Supply Chain Solutions and the FedEx form for FedEx Freight to avoid processing friction.
- Identify the Mode: Choose the Air Waybill for speed-sensitive air transit and the Bill of Lading for traditional ground transportation.
- Compliance Needs: If your shipment involves complex export licenses, the UPS Shipper’s Letter of Instruction provides the necessary fields for regulatory compliance that a standard Bill of Lading may lack.

Tips for freight forms
AI-powered tools like Instafill.ai can complete these complex freight forms in under 30 seconds with high accuracy by extracting data from your existing invoices. Your logistics data stays secure during the process, providing a massive time-saving advantage for businesses handling daily shipments.
Incorrect NMFC classes or estimated weights are common mistakes that lead to significant re-billing charges after the carrier weighs the shipment. Always use a certified scale and verify the current freight class to avoid unexpected rate adjustments on your final invoice.
If shipping regulated goods, you must provide the precise UN number, proper shipping name, and emergency contact information on the Bill of Lading. Failure to certify these details accurately can result in shipment rejections, delays, or legal penalties for non-compliance.
When filling out a Shipper’s Letter of Instruction (SLI), ensure the Schedule B or HTS numbers are precise for every commodity. This allows the carrier to file Electronic Export Information correctly, preventing customs holds and ensuring your international shipments remain compliant.
Carrier liability is often limited by weight or tariff rules unless a higher value is explicitly declared on the form. If your cargo is high-value, make sure the declared value section is completed to ensure you have the proper financial protection in the event of loss or damage.
Clearly mark whether the shipment is 'Prepaid' or 'Collect' to avoid billing disputes between the shipper and the consignee. Inconsistent billing terms across multiple forms can lead to shipments being held at the terminal until payment responsibility is manually clarified.
Since the Bill of Lading acts as a receipt for goods in 'apparent good order,' you must note any visible damage or piece-count discrepancies on the form before the driver signs. This documentation is the most critical piece of evidence if you need to file a freight claim later.
Frequently Asked Questions
Freight forms serve as legal contracts and instructional documents between shippers, carriers, and consignees. They ensure that cargo is handled correctly, billed accurately, and complies with transportation regulations. These documents also act as receipts and provide evidence of the condition of goods at the time of pickup.
A Bill of Lading (BOL) is typically used for domestic ground freight and serves as the contract of carriage and receipt of goods. A Shipper’s Letter of Instruction (SLI) is often used for international air or ocean freight to provide specific routing and export details to a freight forwarder. If you are shipping internationally, you may need both or a combined document depending on the carrier's requirements.
Generally, the shipper or the party initiating the shipment is responsible for providing accurate information on these forms. This ensures that the carrier has the correct delivery address, weight, and classification to move the goods safely. In some cases, a third-party logistics provider (3PL) may assist in preparing the documentation on behalf of the shipper.
Errors on freight forms can lead to delayed shipments, incorrect billing, and potential fines from regulatory bodies, especially for international cargo. Inaccurate weight or freight class can result in re-weighing fees or service failures. Furthermore, incorrect hazardous materials information can create significant safety risks and legal liability.
The National Motor Freight Classification (NMFC) code helps carriers determine the shipping rate based on the density, stowability, handling, and liability of the items. Including the correct code ensures you are billed the appropriate amount for the specific type of goods being transported. Omitting this information often results in the carrier applying a default, often more expensive, classification.
Yes, you can use AI tools like Instafill.ai to automate the completion of complex shipping and logistics forms. These tools can accurately extract data from your commercial invoices or packing lists and place it into the correct fields on forms like the FedEx Bill of Lading or UPS SLI. This significantly reduces manual entry errors and ensures consistency across your shipping documentation.
When using traditional manual methods, these forms can take several minutes to complete accurately; however, using AI-powered tools like Instafill.ai can reduce this time to under 30 seconds. The AI quickly parses your source documents and populates the required fields automatically. This speed is especially beneficial for high-volume shippers who need to process multiple documents daily.
International forms like the UPS SLI/Air Waybill require detailed commodity descriptions, export-control data such as Schedule B or HTS numbers, and ECCN details. You must also specify the service level, payment terms, and whether you are authorizing the carrier to file Electronic Export Information (EEI) on your behalf. These details are critical for customs clearance and international trade compliance.
Yes, a Bill of Lading is a legally binding contract between the shipper and the carrier that outlines the terms and conditions of transportation. It serves three main functions: a receipt for the goods, a document of title, and a contract of carriage. Once signed, both parties are bound by the terms specified, including liability limits and payment obligations.
Most freight forms are handed to the driver at the time of pickup or submitted electronically through the carrier's online portal. For international shipments, copies are also provided to customs brokers or freight forwarders to facilitate the clearance process. It is standard practice to keep a signed copy for your own records to prove the shipment was tendered to the carrier.
