Shipping is visible in the spreadsheet. The margin killer often starts earlier: unclear specs, weak suppliers and goods that were never checked.
1. The lowest price can be the most expensive trap
On 1688, many suppliers use similar photos and aggressive prices. A Brazilian buyer must look past unit price: material, packaging, variation, MOQ, lead time and domestic freight inside China change the real cost.
2. Good suppliers deliver predictability
The central question is not only the price. It is whether the factory or trader can deliver the standard you promise to Brazilian customers. Real videos, confirmed specs and store history reduce expensive mistakes.
3. Multiple suppliers require consolidation
When you buy many SKUs, every supplier ships on a different day with different packaging. Without warehouse control in China, the operation becomes messy before export begins.
4. Basic inspection protects cash flow
Photos, short videos, carton counts and packaging checks do not solve everything, but they reveal obvious problems while there is still time to fix them.
