As per a question that someone posted on HN recently, should all US businesses that rely on goods coming from overseas (especially China) be seeking alternate paths for their goods, like the Vietnam re-shipment example? If the rules are changing by the day, how can anyone be expected to follow them, and what resources are available to monitor and / or enforce these rules? Double that for monitoring / enforcing bastion-country re-shipments? Is import monitoring and enforcement done by federal government employees?
