A dated PDF artifact of a duty determination: the full duty stack, the statute and citation live at the time it was generated, the entry date the rates were applied as of, a stable ID, and a Broker Notes zone you can annotate. It is $99/month including 20 memos, then $15 per memo.

Yes. From any of the three free tools, a memo plus its CSV for your own entry is $19 — one-time, no subscription, no sign-in required. The sample memo + CSV on every tool is always free to download so you can see exactly what you are buying; change anything from the sample and it is treated as a paid $19 memo. For comparison, a subscriber pays $15 per memo after the 20 included each month — so if you file regularly, the subscription is the cheaper way to buy.

Every rate the tools and the memo report is research output, not a customs determination. Verify against the primary source before you file.
