You only need to keep track of bonded stock in CAS. It’s purely an administrative customs stock system. However, CAS has the possibility to do both, you can also store free stock giving you some more opportunities for duty savings.
Example from an EU point of view: if you buy goods from a supplier in China but you also buy the same goods from your local supplier in France for example. If you are then doing a shipment to a customer that is already in the EU, you will then preferably pick the free goods as the duties have already been paid.
So, managing free stock in CAS is not mandatory, but it gives more freedom to make some additional savings.
Upon arrival, your consignment will be completely put under the customs warehouse and your stock will then be maintained in your solution. You can then discharge either the full quantity of the goods all at once or you can split it up into different smaller consignments over time. As a stock administration, if you would for example use CAS, you can get an overview of the remaining stock levels at all times and it will always be linked back to the initial MRN of the import declaration.
In theory, you can apply simultaneously/in parallel for both. These are two different types of warehouses, so two different authorisations and customs regimes. We would advise to get the excise warehouse authorisation first and then apply for a customs warehouse authorisation. If goods come under customs control, the customs warehousing procedure takes priority over the excise warehouse procedure.
No. FIFO is the default setting in CAS, especially with Inward Processing where you have a limited time that the goods can be held. It’s all configurable and up to the customer to decide which system they want to use (FIFO, claim preference, use FTAs, etc.).
The duty rate will be the same, the only thing that will be different is the moment that you need to pay the duties. If you are talking about huge amounts of imports, it can make a very big difference from a cashflow point of view.
Yes, that’s perfectly possible. You can re-export 100% of the goods that you stored in your customs warehouse.
Depending on the jurisdiction, there are different application forms to apply for a customs warehousing authorisation. Typically, you have to give more information on your company, on the location, etc. You will probably get audited on the location.
The EUR1 from the outbound shipment will be taken over from the original inbound shipment. In the CAS stock records, we keep a link to the inbound MRN that we then take over in the outbound shipment. The exceptions can be configured in CAS. The relevant documents that are needed for exception of import duties, can be configured in our decision tables for additional documents.
With the modular system, it’s not mandatory to use the stock management part of it. You can just manage your declarations in CAS, without using the Special Procedures module. Then it’s just a matter of applying the correct CPC code to the declaration.
If you want to use a bonded warehouse partner, it depends on whether your bonded warehouse partner allows to create records for it, so that’s something you would need to check with them.
Because of the liability risks and the excessive reporting requirements, it’s advised to consult with your partner to see whether they are open for you to use that process or not.
Most companies are having their own bonded warehouse, but sometimes they already have a long-lasting relationship with a partner who does everything for them, like a 3PL. And then it’s really up to the partner if he’s acceptable to this or not. If they are, it comes down to looking into how you as a company can provide all required documents, declarations, etc. to that partner. So it’s definitely possible, but it’s a discussion you need to have.
If the return is coming back with the original outbound MRN then we can apply the correct duty rate.
You need to make application to use excise warehousing, in this case in the UK. All authorisation application documents can be found on the HMRC website.
From a basic principle point of view, it’s the same but other rules apply. Temporary Admission will be discussed in our September webinar of the Special Procedures Summer Series.
You need to have a Comprehensive Guarantee to cover a customs warehouse, which is part of the authorisation application.
One of the reasons why we calculate the self-assessed duties in CAS is to see whether your Guarantee still covers the amount of suspended duties in there.
This can depend on the jurisdiction you are in, so we’ll need more information to provide the correct answer.
