There are many reasons why Amazon FBA customers complain about slow logistics.
In this article, Weefreight will share a detailed analysis and corresponding solutions.
Cause Analysis
Capacity Tightening During Peak Logistics Periods: During major promotional events like Prime Day and Black Friday, Amazon warehouse processing volume increases significantly, potentially 3-5 times the normal rate. This leads to significant package backlogs and slows logistics. For example, data from the 2025 peak season showed that the last-mile delivery delay rate in some regions reached as high as 27%.
Transportation Route Planning Flaws: Third-party carriers typically use fixed routes. When order volume in a particular region suddenly increases, the lack of intelligent dynamic route adjustment mechanisms can reduce final delivery efficiency and impact logistics speed.
Increased Customs Clearance Time: In recent years, the inspection rate of cross-border e-commerce packages has increased, especially for products like electronic devices and cosmetics. The average customs clearance time can extend to 5-7 business days, which undoubtedly increases the overall logistics process.
Insufficient last-mile delivery resources: In some remote areas, the coverage rate of partner delivery points may be less than 60%. Some rural areas even require multiple transfers for final delivery, which can easily lead to slow logistics.
Improper inventory management: Sellers fail to replenish inventory promptly or fail to accurately estimate sales, resulting in inventory shortages and delayed order fulfillment, which can cause customers to perceive slow logistics.
Amazon warehouse operational issues: For example, when a warehouse is overwhelmed, even if goods have been signed for, they cannot be successfully put into the warehouse, requiring a long wait. There are also issues such as unclear labels leading to rejections and scanner recognition software not being updated, which can affect the normal processing and delivery of goods.
Solutions
Choosing a high-quality logistics provider: Choose a service provider with an intelligent routing system, such as UPS My Choice. Its dynamic scheduling algorithm can improve delivery time by 18%. Furthermore, require carriers to provide real-time tracking APIs, which can reduce the response time for identifying abnormal packages to within 2 hours.
Optimize inventory layout: Leverage Amazon’s Inventory Placement service to build a three-tier inventory network based on sales data forecasts. Pre-position core SKUs to transit warehouses near target markets, reducing final delivery times by 40%.
Join the Official Partnered Carrier Program: Join the Amazon Partnered Carrier Program (PCP) to enjoy exclusive capacity quotas and priority handling. Test data shows that sellers using Amazon Freight see a 92% increase in on-time delivery rates during peak season.
Prepare for customs clearance: Prepare customs clearance documents such as commercial invoices, packing lists, certificates of origin, and product compliance certificates in advance. Request the latest declaration requirements from your logistics provider for the destination country’s customs. Use DDP terms to avoid tax disputes and minimize customs clearance delays.
Strengthen customer communication: Set up delivery time alerts on product detail pages and establish an automated email notification system to inform customers of potential order delays. This can reduce negative customer reviews by 31%. When customers complain, respond promptly and offer solutions, such as coupons or discounts.
Optimize product packaging and labeling: Optimize product packaging to reduce volume and weight, improving sorting and packing efficiency. Use a high-precision printer, such as the Zebra GK420d, for labeling to ensure clarity and accuracy. Take six-sided photos and a weighing video before shipping to provide evidence in case of any issues.
