Why we publish this

Most packaging sourcing problems are information problems: a missing weight table, a barrier assumption, a document that arrives after the vessel sails. Publishing how we work is the cheapest way to show what a buyer should expect from a supplier — including from us.

What this knowledge base covers

These guides answer the questions that decide whether an order runs smoothly: which material suits the product, what the EU packaging rules require from 12 August 2026, what a declaration of conformity and a technical file actually contain, how incoterms and HS classification shape the landed cost, and how minimum order quantities are really calculated.

Every page is written to be checked rather than believed. Dates, regulation numbers and document names are given so your compliance or quality team can verify them against the official source, and the pages are dated at the bottom because EU rules and national rules move.

If a question you need answered is not here, send it with your enquiry — the questions buyers ask most often are the ones that get written up next.
