FBA 尺寸分级
按包装尺寸和重量把商品分进 small standard / large standard / large bulky / extra-large——分级+重量段一起决定配送费。
档位边界是悬崖：跨一档,重新给你出过的每一件定价。这让包装工程成了财务职能——重新设计包装降一档买回的毛利,任何谈判都谈不来。确认亚马逊档案里的分级和你的实际包装一致,分错的会一直错到你挑战为止。
关键数字
费率与规则以官方英文原文为准，保留原文：
- US tiers: small standard, large standard, large bulky, extra-large (with weight bands inside each).
- Small standard cutoffs sit around ≤16 oz and envelope-scale dimensions; large standard covers most products up to ~20 lb.
- Tier follows packaged dimensions — packaging changes can move a product down a tier permanently.
