In general, people have no idea how complicated these things are, believe me I worked for 10 years on international commerce and I know a bit
Basically, if a client from the EU wants to buy from you in the UK, is a 30 min job. They place the order (usually online) fill the form, make the payment. They give you their VAT number and you don’t apply the 20% surcharge to avoid double taxation (as per EU agreement between members.
The system automatically sends an Sales Order Acknowledgement to the client and your warehouse, the order is picked, packed and moved to dispatch, administration personnel create the Airway Bill that notifies the courier company of the dispatch.
If you do this before 12:30 and you are situated near the M25 in London, a white van will pick the order the same day and move it to heathrow, from there a flight to any european capital every couple of hours, the same day it will arrive to the destination airport, into another van and delivered to the customer next morning. All of this can be done in 24 hours on a good day, 48 on average and 72 on a really shitty week. Job done, money in the bank, client satisfied
Now, if a client from a third country wants to buy something, the end user starts the process by talking to their purchasing department, they talk to their international procurement department… if the company is big enough, then they start asking for documentation, papers, customs declarations, certificates of origin, certificates of provenance, microbiology certificates, MSDS, etc, often hard copies are required, often in triplicated and very often in the local language.
Soon you are talking simultaneously to people in the purchasing department, the finance department, the legal department, customs officials, customs agents, dispatchers, couriers… 10 - 15 people, all of them drawing a salary from your sale in the form of taxes, import tariffs, professional fees.
After 3 weeks, if everything has gone well, you dispatch and cross your fingers that everything goes well. If it does, it could be 2 - 3 weeks to get clearance (it could be less, depends on the country), up to a month in customs and you are ok. After 4 weeks they start charging warehousing and after 3 months the goods are either returned at your expense or destroyed. So you better get it right, because the customs officials are not there to help.
The job of customs officials is NOT to facilitate commerce, is to disrupt it in a controlled manner.
And then we have to talk about the import taxes, which vary from country to country, most extreme case is Brazil, 100% of the declared value, no exception. That is how you end up with nintendo having to decide between selling consoles for 800 USD retail price or not selling them at all (they decided to pull out of the country entirely). That is one of the reasons why is so important to negotiate the INCOTERMS correctly with the customer, if you mess up, the hit can wipe out all the profit of the sale. Just like that, gone, now you are working for the man, and the client is still waiting to receive the goods, and they haven’t even processed the invoice for payment, and payment terms are 120 days, and their government charges 25% taxes to all payments in USD outside the country…
I have seen things you wouldn’t believe. A drinks manufacturing plant in Angola that had to have in storage everything they needed to run the plant for 6 months, from nuts and bolts to soap for the toilets, uniforms, spares, sugar, concentrate… everything except local food for the cafeteria and water.
In our case, many goods destined to the UK are shipped in container ships to the Netherlands and then trucked in, even if they want to ship directly to the UK they can’t because there is no enough capacity in the ports.
Its going to be… interesting
