When it comes to expanding internationally and offering their products on Amazon in different countries, many Amazon sellers are often faced with complex sales tax regulations and logistics challenges. The good news is that Amazon has found a solution to these hurdles - the Call-Off Stock (COS) or consignment stock program. In this blog post, you'll learn everything you need to know about COS, how it works and the benefits it offers.

What is call-off stock (COS)?

Call-Off Stock (COS, consignment stock program) is an innovative program from Amazon that makes use of an EU-wide simplification of VAT legislation. It allows sellers to store their stock in a country of their choice without the need for a VAT identification number in that country.

COS is currently available in France and Spain, with more countries to follow in 2023. In order to participate in the COS program, you must meet certain legal requirements. These include, for example, that you must know the "intended purchaser" who will ultimately purchase your stock from the COS. You must comply with the VAT reporting obligations in the country in which you are registered for VAT and from which the goods are shipped. In addition, unsold stock stored under the COS must not remain in the COS country for more than 12 months and must be returned to the original country of dispatch before this period expires.

In addition, you must not have a branch in a country for which COS is activated. These conditions are implemented by Amazon buying your inventory (B2B) and then reselling it to a customer at the time of purchase (B2C). You remain the owner of your inventory as it moves within the European network of Amazon logistics centers in the countries you have activated for storage. Do you need support with Selling on Amazon?

Are there any additional tax requirements for registering with Pan-EU FBA via COS?

Yes, there are some tax requirements that you must meet if you participate in the COS program. You must comply with VAT reporting requirements, including submitting recapitulative statements (SRs) to the tax authority of the country from which the goods are shipped. This applies in particular if you already have stock in several countries and are already obliged to submit recapitulative statements. During the beta program, you can use the required information from the Amazon Value Added Tax Transaction Report (AVTR) to identify COS sales and inventory movements between the shipping country and the COS warehouse country.

How does participation in the COS program work?

To register for COS, simply go to your "Shipping by Amazon" settings in Seller Central and select the countries where you want to place the inventory. Once you've signed up, all of your eligible ASINs will be registered for the COS program.
