Peak season starts long before Black Friday.
For the logistics team, Q4 begins when forecasts are agreed, inbound stock is booked, product data is loaded, customs responsibility is set and delivery capacity is tested.
That is why August matters.
If the route is only tested when order volume rises, the business is testing it on live customers.
Check the product data
Start with the products you expect to sell most.
Are descriptions clear enough for customs?
Are tariff codes and values checked?
Is the same information used by the seller, warehouse, carrier and customs team?
A small data error repeated across thousands of orders becomes a peak-season problem.
Check who owns customs and duty
The commercial terms should be clear before orders increase.
Who is the importer?
Who makes the customs declaration?
Who pays duty and tax?
Does the customer know the final landed cost?
If the route can change between DDP, DAP or other delivery terms, the team needs to understand what that changes for the customer and the customs process.
Check where inbound stock will sit
Peak stock often arrives before it is needed.
For eligible goods, an ETSF or Customs Warehouse may provide a controlled place to hold stock before final UK release or onward movement.
The question is not whether bonded warehousing is always the answer. It is whether the business has planned where each type of stock can legally wait.
Check the release and delivery handover
A customs release is only useful if the warehouse and delivery provider act on it correctly.
At higher volume, unclear ownership creates queues and repeated checking.
Make sure the team knows who receives the release message, who updates the stock status and who hands the goods to the next carrier or postal network.
Check the return before the sale
Peak sales create a return cycle.
The outbound process should preserve the information needed to identify a returned item, match it to the original movement, grade it and decide whether it can be re-dispatched, recycled or dealt with another way.
What about low-value import reform?
The UK government plans to change the customs treatment of low-value imports, including removing the current £135 customs duty relief, with implementation planned by October 2028 at the latest.
That future change is worth watching.
But the reason to act in August 2026 is much closer: Q4.
