Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢eu_duty_estimate(lines, consignment_value_eur, channel, date)
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).

}🟢customs_data_gap_check(csv)
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.

}🟢bulk_hs_candidates(products, markets)
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.

}🟢landed_cost_estimate(hs_code, destination, goods_value, shipping, origin, ...)
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).

Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name.
