Final answer:
Federal law does not specifically address the payment timing of freight bills in Section 9 Clause 6, which focuses on preventing unfair state taxation and regulation. Payment terms are usually stipulated in contracts and can vary but are often set at standard intervals like 30 days post-delivery.
Step-by-step explanation:
The time frame for payment of freight bills from shipper to broker according to federal law is not specifically addressed in the Section 9 Clause 6 information provided. This clause pertains to the prohibition of unfair taxation or regulation favoring one state's ports over another. To ensure accuracy about the payment terms of freight bills according to federal laws, it is important to consult the most current legal documentation or industry standards, such as the Uniform Commercial Code or regulations from the Federal Motor Carrier Safety Administration.
Typically, payment terms are agreed upon in contracts between the shipping parties and may vary as per negotiations but are often standardized to a certain number of days post-delivery, such as 30 days. These agreements are generally dictated by industry norms or organizational policies rather than being strictly legislated.
