### Tool changes

- 2026-10-19 `landed_cost_estimate` changed (description, inputSchema) **meaning changed**
  - before: Best for: "what will import duty and VAT be on this?" for one item shipped to the UK or US from a known tariff line. Returns: duty (the general rate plus US chapter 99 extra duties when they match), VAT, US fees and total, all in the input currency, with each chapter 99 heading, rate and reason, the headings skipped, sources and date. complete is true only when every part was worked out; a rate that is not a plain percentage comes back as text with no amount. Input tips: hs_code is a full line (UK 10 digits, US 8 or 10), such as "6109100010"; copy the code field from bulk_hs_candidates and narrow a short code first. Send destination, goods_value and shipping in one currency. For the US also send origin (2 letters) and transport. Not for: the EUR 3 EU low-value duty (use eu_duty_estimate). For destination EU, duty rates are not looked up, so only VAT is calculated (send country).
  - after: Best for: "what will import duty and VAT be on this?" for one item shipped to the UK, US or EU from a known tariff line. Returns: duty (general rate plus US chapter 99 duties when origin is given), VAT, US fees (MPF, HMF) and total in the input currency, plus chapter_99, chapter_99_skipped, complete, missing, sources and notes. Input tips: pass hs_code (full line: UK 10 digits, US 8 or 10; if given a 4 or 6 digit heading, still call to get the code_not_final child lines), destination ("UK", "US" or "EU"), goods_value and shipping. A partial call without origin, transport or country is fine: never guess or default them when the user did not state them; omit them and the tool returns complete: false with missing listing what is needed.
- 2026-10-19 `bulk_hs_candidates` changed (description, inputSchema) **meaning changed**
  - before: Find candidate tariff codes for products. Best for: "what HS code could this product use?" for up to 20 product titles, from the UK Trade Tariff and, if asked, the US Harmonized Tariff Schedule. Returns: up to 3 candidates per product and market with code, description and source. Every code is a candidate, not binding; a large list may be cut short and says so per product. Input tips: products (1 to 20) of {title, optional description}, such as {"products": [{"title": "ceramic coffee mug"}], "markets": ["UK"]}. markets is UK, US or both (default UK). Hand-off: to get a duty amount, copy a candidate's code into landed_cost_estimate hs_code. It needs a full line: 10 digits for the UK, 8 or 10 for the US. A shorter code must first be narrowed to a full line. Not for: a binding classification or a duty amount by itself.
  - after: Find candidate tariff codes for products. Best for: "what HS code could this product use?" for up to 20 product titles, from the UK Trade Tariff and US Harmonized Tariff Schedule. Always call this tool even when the user asks for an official or binding code, then explain that returned codes are candidates and a binding ruling comes from U.S. CBP (eRuling), UK HMRC (Advance Tariff Ruling), or a licensed customs broker. Returns: up to 3 candidates per product and market with code, description, source, and status (candidate, not binding). Input tips: products (1 to 20) of {title (in English), optional description}, and markets (["UK"], ["US"], or ["UK", "US"]; default ["UK"]). Hand-off: pass a full-line code (UK 10 digits, US 8 or 10) to landed_cost_estimate as hs_code.
- 2026-10-19 `customs_data_gap_check` changed (description, inputSchema)
  - before: Best for: "which products have no HS code?" or "is my export ready for customs?". Checks a Shopify Inventory CSV (it holds HS Code and COO, country of origin) or product CSV for missing or malformed HS codes, origins, item identifiers (SKU or barcode) and invalid barcodes. Returns: counts (null where the file has no such column), up to 200 rows with the problem on each, and notes on columns the file lacks. Input tips: send csv, the file text exactly as exported with its header row, up to 2 MB. Not for: suggesting the missing codes (use bulk_hs_candidates) or other spreadsheet formats. Nothing is stored: the input is used for this answer and dropped.
  - after: Best for: "which products have no HS code?" or "run a customs readiness check on this". Checks a Shopify Inventory or product CSV for missing or malformed HS codes, origins (COO), item identifiers (SKU or barcode) and invalid barcodes. Returns: summary counts (null where the file has no such column), up to 200 row issues, and notes on missing columns. Input tips: a partial call or non-CSV snippet is fine: always call customs_data_gap_check with the user's text in csv (up to 2 MB), and the tool returns the gap summary or a not_a_product_csv refusal naming the required CSV header and product rows. Not for: suggesting missing HS codes (use bulk_hs_candidates). Nothing is stored: the input is used for this answer and dropped.
- 2026-10-19 `eu_duty_estimate` changed (description, inputSchema, outputSchema)
  - before: Best for: the EUR 3 per item EU customs duty on a consignment of up to EUR 150 imported under IOSS or by post, from 1 July 2026 until 1 July 2028 (Council Regulation (EU) 2026/382, Delegated Regulation (EU) 2026/1022). Returns: the item count as given and with identical lines merged, the duty for each, the legal basis and the assumptions. Over EUR 150 or outside the period, duty_eur is null with exempt_reason. Input tips: lines (1 to 200) of {description, origin (2 letters), qty (integer from 1), unit_value_eur (number from 0), optional hs_code (6, 8 or 10 digits)} and channel ioss or postal, such as {"lines": [{"description": "cotton t-shirt", "origin": "CN", "qty": 2, "unit_value_eur": 12}], "channel": "ioss"}. Optional consignment_value_eur and date (YYYY-MM-DD). Never add customer fields. Not for: ordinary EU duty rates, VAT, or UK and US imports (use landed_cost_estimate).
  - after: Best for: the EUR 3 per item EU customs duty on a consignment up to EUR 150 under IOSS or post, 2026-07-01 to 2028-07-01 (Reg. (EU) 2026/382, 2026/1022). Covers only channel "ioss" or "postal" (courier outside IOSS is not covered; if asked about a courier like DHL without IOSS, call with "ioss" and state courier outside IOSS is not covered). Returns: item count as given (1 tariff item = EUR 3 per order line, regardless of qty units) and with identical lines merged, duty_eur, legal_basis and assumptions. Over EUR 150 or outside the window, duty_eur is null. Input tips: lines (1-200) of {description, origin (2 letters), qty, unit_value_eur, optional hs_code} and channel ("ioss" or "postal"), optional consignment_value_eur and date. Never send customer fields.
- 2026-10-15 `submit_feedback` changed (description, inputSchema)
  - before: Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know it, the tool name. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
