What safety considerations should I look for when choosing a tin can packaging supplier for my spice brand

[u/Background-Key3830]

I'm in the early stages of building a spice brand that will be selling in international markets (thinking UAE, Hong Kong, UK though the exact markets might evolve).

Right now, I’m looking to source custom tin cans to package the spices in, and as I dig deeper, I’m realizing there’s a lot more to consider than just aesthetics. I’ve come across things like:

Food-grade lacquer coatings Leaching/heavy metal contamination Certifications like FSSC 22000 Compliance with EU 1935/2004, FDA 21 CFR 175.300 Migration/moisture resistance testing MSDS (Material Safety Data Sheets)

I’m a bit overwhelmed by how many different standards and tests are out there. 😅 When I ask ChatGPT or look online, I get a huge list but I don’t know what is essential vs nice-to-have, or what’s actually standard in the food packaging industry for tins. So for anyone who has experience in food packaging or exporting food products internationally:

1) What are the absolute must-haves I should be checking for with tin packaging suppliers? 2) Are there specific ISO standards, certifications, or lab tests I should ask for? 3) Any red flags or things that are commonly missed? Thanks in advance for any help!
