Paying a supplier
Proforma invoices, deposits, Incoterms and red flags.
Read guide →Updated July 2026 · by the Qula Craft Sourcing Team — the people who quote and pack these lines every week.

The number that decides whether your margin works is not the price per bag. It is:
Two quotes can only be compared once both are converted to this figure. That is also why the Incoterms rule on the invoice matters so much — the ICC's Incoterms® rules define which of those cost lines the seller already covered and which are still coming toward you.
Every traded product is classified under the Harmonized System. The US International Trade Administration explains that the HS assigns six-digit codes internationally, which the United States extends to ten digits for imports. Other countries extend it to eight or ten digits of their own.
Practical implications for craft supplies:
We can tell you what the goods physically are — material, composition, pack format — which is exactly what a broker needs to classify them correctly. We do not guess at your national tariff line, because getting that wrong is your risk, not ours.
Duty rates change, and they differ by country, by trade agreement and sometimes by month. Any guide that prints a percentage will be wrong eventually — so use the official sources instead:
Check the rate yourself close to shipment date rather than relying on a figure quoted months earlier.
This is where craft supply importers get surprised. A bag of foam-light filler weighs almost nothing but fills a carton. Air freight and courier services bill on volumetric weight — a formula based on carton dimensions — whenever that exceeds actual weight, which for these products it usually does.
So the useful question to your supplier is not “how heavy is it?” but “what are the carton dimensions and how many bags per carton?” With that you can get a real quote from a forwarder instead of an estimate. We include carton data with every quotation for exactly this reason.
Two consequences worth planning around: consolidating several stock lines into one shipment usually beats several small parcels, and compressible pack formats (bags rather than rigid jars) can meaningfully cut the volumetric bill.
Under DDP the seller handles clearance and duty, which is why it suits first orders — you get one number and no paperwork. Under FOB or EXW you or your broker clear the goods, and you will need the commercial invoice, packing list and, depending on the destination and product, any applicable compliance paperwork.
For craft supplies sold into children's channels, retailers commonly ask for batch test reports such as EN 71, ASTM F963, CPC or REACH. Those are supplied on request — see our non-food safety labeling guide for how the wording works on the retail pack.
Tell us the products, quantities and destination country. The quotation comes back with pack format and carton dimensions so you can price freight and duty properly before you commit.
