Check whether dangerous goods qualify for ADR Limited Quantity (LQ, ADR 3.4) or Excepted Quantity (EQ, ADR 3.5) relief. LQ compares each item's per-inner-packaging quantity against that substance's LQ maximum; EQ resolves the substance's E-code (E0-E5) and checks the per-inner limit, plus the per-outer limit when inner_packaging_qty is given. Provide mode ("lq" or "eq") and 1-20 items, each with un_number, quantity and unit — ml or L for liquids, g or kg for solids; quantity is per INNER packaging, not the whole load. Multi-variant UNs: a UN number with more than one ADR Table A row (packing group / concentration variant — e.g. UN 1789 PG II LQ 1 L vs PG III LQ 5 L) needs packing_group (I|II|III) or variant_index (from adr_lookup) on that item to pin one row. Without a disambiguator the tool returns blocking_errors[AMBIGUOUS_UN_VARIANT] + human_review_required + candidates[] (each candidate's variant_index, packing_group, proper_shipping_name, limited_quantity, excepted_quantity) and NO verdict, rather than silently checking the wrong packing group. Single-row UNs are unchanged. Behavior: deterministic reference check; each item gets a status and reason (an LQ value of "0" or code E0 means the relief is not permitted for that substance), with overall_status and summary counts across the batch. Table A rows listed "NOT SUBJECT TO ADR" (e.g. UN 1845 dry ice) get item status not_subject — outside ADR scope, neither a pass nor a fail — and an all-not-subject batch returns overall_status not_applicable; "CARRIAGE PROHIBITED" rows are not_permitted with the prohibition stated in reason. Rate-limited (anonymous use: 25 requests/day per IP): a 429 error body carries retry_after_seconds and a Retry-After header — back off and retry, or call get_subscribe_link for higher limits. Returns: mode, overall_status (qualifies | does_not_qualify | partial | not_applicable), items[] (un_number, variant_index, substance, class, packing_group, lq_limit or eq_code, quantity_entered, status, reason, and scope flags where applicable), summary {total_items, qualifying, exceeding, not_permitted, not_subject?} and the ADR chapter references under result — or, when a UN is ambiguous, human_review_required + candidates[] with blocking_errors, plus confidence, _source and citation (the FreightUtils v1 response envelope). Limitations: a quantity-threshold check only — LQ/EQ relief also requires packaging, marking and documentation conformity that this tool does not assess; not legal advice, verify against the current UNECE ADR text. Related: adr_lookup (the per-substance LQ/EQ values + variant_index), adr_exemption_calculator (the 1.1.3.6 load-points route instead).
