Bringing Two New Products Into the UK – Best Way to Launch FBA Listings?

I’ve been working with a manufacturer for years and recently secured a contract for two products that I believe have good potential in the UK. I now have the ability to import them and hold stock locally (EORI already sorted).

My next step is to build the listings for the UK market under my own company, and I want to make sure I set things up right from the start.

For those of you with experience expanding into the UK:

• What are the key things you focus on when creating new listings for FBA?
• Are there any pitfalls around compliance, shipping, or listing optimization that I should keep in mind before sending stock?
• Any tips on balancing between testing demand with smaller quantities vs. committing to larger shipments up front?

I’d appreciate hearing from anyone who has gone through the process of launching new products into the UK via Amazon FBA.
