Yarn is a high-volume, low-weight product, so vacuum packaging can significantly reduce the shipping volume and lower freight costs. For shipping to North America or Europe, compare FOB (Free On Board) and CIF (Cost, Insurance, and Freight) terms; usually, FOB allows the buyer better control over demurrage and detention fees at the destination port. Ensure the supplier provides a detailed packing list and Certificate of Origin to facilitate smooth customs clearance and potential tariff exemptions.
