52.247-10
Net Weight-General Freight
Contractors must use certified weighmasters and scales to determine net shipment weight and provide original weight certificates with their invoices for general freight transportation services.
Overview
FAR 52.247-10, Net Weight-General Freight, establishes the method for determining the net weight of freight shipments (excluding household goods and office furniture) when the weight is unknown at the time of shipment and the contractor is responsible for weight determination. The clause requires contractors to use certified weighmasters and certified scales to obtain both the tare (empty) and gross (loaded) vehicle weights, ensuring accuracy and accountability in billing and transportation documentation.
Key Rules
- Net Weight Determination
- Contractors must determine net weight by subtracting the tare weight (empty vehicle with full fuel) from the gross weight (loaded vehicle with full fuel), both measured by a certified weighmaster on a certified scale.
- Documentation Requirement
- Contractors are required to attach the original weight certificates (for both empty and loaded vehicle) to the invoice for transportation services.
Responsibilities
- Contracting Officers: Ensure the clause is included in applicable contracts and verify compliance during invoice review.
- Contractors: Accurately determine net weight using certified methods and provide required documentation with invoices.
- Agencies: Oversee contract compliance and maintain records for audit and payment purposes.
Practical Implications
- This clause ensures transparency and fairness in billing for freight transportation services where shipment weight is not pre-determined. It protects both the government and contractors by standardizing weight determination and documentation, reducing disputes and potential overcharges. Common pitfalls include failure to use certified scales or missing/incomplete weight certificates, which can delay payment or result in noncompliance findings.
