Field notes
Each change is organized around four practical questions: who is affected, what it costs, when it takes effect, and what the seller should check. The first issue includes a temporary 6 percent USPS peak-season increase and a CBP warning about inaccurate Form 5106 importer data. Source transparency is unusually visible: the page reports sentence-level matches, exposes quoted passages, and links readers to the underlying government document.
