Tools

• calculate_saving

  Purpose: substitution economics compute for carbon black - given a native price (vcb_price_input), an rCB price (rcb_price_input) and replacement ratio, returns per-ton saving and optional annualized value. Guidelines: supply your own quotes, or fetch market anchors via get_rcb_index first. Limits: pure arithmetic - no market data access, not a price recommendation. Ex: 'N330 12000 RMB/t vs rCB 8000 RMB/t, ratio 0.3, annual 5000t'.

  shallow
• compare_rcb

  Purpose: quality benchmark - compare measured rCB sample parameters against a target native carbon black grade (e.g. N550) spec ranges; classify each parameter pass / light deviation / significant deviation. Guidelines: pass target_grade plus rcb_params (iodine_absorption, OAN, ash...); ideal for grading incoming rCB lots against a native anchor before substitution decisions. Limits: needs measured values as input - no lab data on file; thresholds follow the site's anchored-benchmark methodology, not customer specs. Ex: 'compare rCB sample vs N550'.

  shallow
• get_announcements_timeline

  Purpose: return a chronological timeline of company announcements across the rCB industry - results, capacity, certification and delivery approvals. Guidelines: filter by region and by date range (YYYY-MM-DD) to isolate a window; use alongside query_companies when tracking capacity build-out, and with query_policies when a regulatory date drives an announcement. Limits: announcement-derived items only - claims are not independently confirmed and full press-release text is not served; coverage depends on what companies have publicly announced, so absence is not evidence of inactivity. Ex: get_announcements_timeline(region='欧洲'), get_announcements_timeline(date_from='2026-01-01', limit=50).

  shallow
• get_database_overview

  获取数据源概况：版本、条目数、实体 ID 规则、置信度分级说明、可用工具清单与站点模块入口。首次接入时建议先调用。Bilingual: pass language='en' for English output.

  shallow
• get_elt_price_index

  Purpose: rCB feedstock (end-of-life tyre) price index in GLOBAL caliber - Tier 1 global categories (scrap tyre collection price / tyre pyrolysis oil / crumb rubber / recovered steel wire / rCB) with region-by-region indices benchmarked to the global weighted average = 1000, plus Tier 2 region-specific categories (EU/US gate fee and TDF; CN rubber fuzz, rubber block, 900-mesh and 24-mesh powder). The first category is the scrap tyre collection price (G-ELT) - the single largest cost item for rCB producers. Guidelines: no arguments returns the global cross-section with region spreads; pass region (EU/US/CN/CA/IN) for that region's index across categories; pass category (G-TPO/G-CRB/G-WIRE/G-RCB) for one category's region comparison. Pair with get_feedstock_overview for arisings and processing paths, and get_rcb_index for layered rCB product prices. Limits: index values, region spreads and ratios only - absolute prices and source platforms are never disclosed because no official public statistics source exists for ELT feedstock prices worldwide; some regions are excluded from a category when the product caliber is not comparable (e.g. China's bead wire is a finished product vs the recovered mixed wire traded in the EU/US). Ex: 'global tyre pyrolysis oil price index vs China', 'crumb rubber price by region', 'which region has the highest TPO price'.

  shallow
• get_elt_recycling

  Purpose: the end-of-life tyre (ELT) collection topic for the rCB supply chain - policy targets, the 2026 standard system, the collection-network build-out, the processing value ladder (retreading > recycled rubber > pyrolysis) and market-size figures, with official sources labelled per record. Guidelines: call with no arguments for the full topic, or pass topic (policy/standard/network/ladder/market) to focus one section; pair with get_elt_price_index (category G-ELT) for collection prices and get_feedstock_overview for arisings. Limits: policy and standard records are sourced from official documents; market-size figures are public-information compilations and labelled as such; does not return prices. Ex: 'China end-of-life tyre recycling policy 2030 target', 'ELT collection network China', 'scrap tyre pyrolysis standards 2026'.

  shallow
• get_feedstock_overview

  Purpose: overview of the rCB feedstock module beyond prices - waste tyre arisings and recovery volumes by region (China, EU, US, global) with official sources, the processing-path value ladder (retreading > material recycling > energy recovery > civil engineering > landfill), and the categories covered by the module. Guidelines: pass region (CN/EU/US) to focus the arisings table; use this before quoting feedstock availability or recovery-rate figures, then get_elt_price_index for prices. Limits: arisings and recovery rates are drawn from official and industry-association sources with the statistical body labelled per record - figures from different bodies differ by scope and must not be merged; does not return prices. Ex: 'waste tyre recovery volume China 2025', 'how are end-of-life tyres processed', 'EU tyre recovery rate'.

  shallow
• get_grade

  按语义化实体 ID（如 rcb-grade-n550、rcb-grade-rcb-general）获取单条牌号的完整详情。返回：6 项 ASTM 标准指标的 min/max 范围表 + ASTM 检测方法标准号 + 应用场景列表 + 工艺路线 + rCB 类型特有 vs 原生 N550 锚点的差距分析（吸碘/DBP/BET/灰分/加热减量/筛余物六项）。支持中英双语与 JSON 结构化输出（response_format='json'，含完整 params 对象）。

  shallow
• get_grade_spec

  Purpose: ASTM spec parameter ranges (min/max/unit/test method) for native carbon black grades N110-N990, conductive benchmarks and rCB grades - the standard-parameters reference for carbon black. Guidelines: pass grade (e.g. n330, n550) plus optional type (native/conductive/rcb); use to judge whether an rCB sample falls in spec (iodine absorption, OAN, SAOAN, ash, pH). Limits: spec ranges only - not lot-specific CoA data. Ex: 'N330 standard parameters', 'rCB N550 spec vs ASTM'.

  shallow
• get_grade_trend

  Purpose: return the historical series of the layered rCB index for one grade tier - period-by-period assessed benchmark price, period-on-period change, anchor, adjustment factor and verification factor. Guidelines: grade defaults to P2 in the CN region; set start_date and end_date as YYYY-MM to slice a window; pair with get_rcb_index for the current cross-section and get_price_trend for category-level trends. Limits: index points only - dimensionless, non-tradable, and never to be converted into an absolute price; early periods may carry an anchor carried forward from an earlier month, and the output flags when this happens. Ex: get_grade_trend(grade='P2'), get_grade_trend(grade='P1', start_date='2025-12', end_date='2026-09').

  shallow
• get_policy

  按实体 ID（如 rcb-pol-001）或名称关键词，获取单条政策法规的完整详情。返回：发布/归口机构、政策类型、适用范围、对 rCB 产业影响解读、合规截止日期、来源链接与 AI 可读摘要。支持中英双语与 JSON 结构化输出。

  shallow
• get_price_trend

  Purpose: native carbon black / rCB price trend direction with official anchors only (no raw quote tables). Guidelines: pass optional segment (domestic/export/import/feedstock/rCB) and period (e.g. 2026); use for directional questions like 'is rCB price rising'. Limits: trend direction and anchors only - no absolute quotes; pair with get_rcb_index for numbers. Ex: 'rCB price trend 2026 CN'.

  shallow
• get_rcb_index

  Purpose: rCB price index query - returns the index (ABP), absolute reference price (ARP, USD/ton FOB) and AF/VF attribution decomposition for a grade level, period and region; native-carbon-black-anchored (N550 anchor method). Guidelines: pass grade (P1 refined / P2 standard / P3 industrial, default P2), date (YYYY-MM, blank = latest) and region (CN/EU/NA/SEA, default CN); pair with get_rcb_vcb_spread for discount and get_grade_trend for history. Limits: reference range computed from the anchor method - not a transaction price; VF factor is forward-only (no backfill before 2026-Q3). Ex: 'rCB index P2 CN 2026-09', 'current rCB reference price EU'.

  shallow
• get_rcb_vcb_spread

  Purpose: anchored spread between rCB and native carbon black - anchoring ratio rho, discount rate and price gap per grade/region/period; the quantitative 'how much cheaper is rCB' indicator. Guidelines: pass date (YYYY-MM), region (CN/EU/NA/SEA), grade (P1/P2/P3); pair with get_grade_trend for direction and calculate_saving for custom quotes. Limits: N550-anchored reference range, not transaction price; single-period snapshot, no forecast. Ex: 'rCB vs N550 discount CN 2026-09'.

  shallow
• get_substitution_boundary

  Purpose: four-dimension substitution boundary of rCB vs native carbon black - application limits, regulatory access, certification requirements, material spec constraints. Guidelines: pass dimension in {application, regulatory, certification, material_spec} or omit for all four; call before any substitution feasibility claim (e.g. 'can rCB replace N330 in tire?'). Limits: technical/regulatory possibility only, not commercial viability - pricing belongs to calculate_saving. Ex: 'rCB application limit in seals', 'rCB regulatory access EU'.

  shallow
• get_tech

  按实体 ID（如 rcb-tech-001）或标准号/名称关键词，获取单条技术标准的完整详情。返回：标准编号、归口机构、适用范围、核心技术指标、适用对象、来源链接与 AI 可读摘要。支持中英双语与 JSON 结构化输出。

  shallow
• get_trade_dataset_overview

  Purpose: describe the trade flow dataset - source, caliber, unit conversion, derived-field declarations, field table and compliance boundaries - so an agent can cite and interpret it correctly. Guidelines: call this before running any trade query that will be quoted; it states explicitly which fields are customs-reported and which are our own derivations. Limits: UN Comtrade official statistics only - no commercial quote platform data enters this dataset; this tool documents the dataset and returns no trade records itself. Ex: get_trade_dataset_overview(), get_trade_dataset_overview(response_format='json').

  shallow
• get_trade_flow_summary

  Purpose: aggregate the UN Comtrade carbon black (HS 280300) records for a period - per reporter totals for quantity and value, the weighted unit price, and the top-10 partner countries by quantity. Guidelines: pass period (YYYY) or leave empty to aggregate all periods (2024-2025); weighted price equals total value divided by total quantity; pair with get_trade_partner_ranking to drill into a single reporter. Limits: customs-reported totals only - no commercial quote platform data; World aggregate rows are excluded from partner rankings; unit prices are not comparable across reporters where quantity reporting is incomplete. Ex: get_trade_flow_summary(period='2025'), get_trade_flow_summary(response_format='json').

  shallow
• get_trade_partner_ranking

  Purpose: rank partner countries for one reporter, period and flow direction by quantity, returning rank, partner, quantity, value, unit price and share. Guidelines: reporter (ISO3 alpha), period (YYYY) and flow (X =export, M = import) are required; raise top_n above the default 10 (max 50) only when a longer tail is needed.Limits: one reporter-period-flow combination per call; World aggregate rows are excluded; shares are computed within the returned set, not against global trade. Ex: get_trade_partner_ranking(reporter='CHN', period='2025', flow='X'), get_trade_partner_ranking(reporter='USA', period='2024', flow='M', top_n=20).

  shallow
• query_cards

  Purpose: search the public knowledge-card collection - atomic sourced facts compiled from statistics, standards, papers and official announcements. Guidelines: keyword matches title and fact fields; combine type and region to narrow; every card returns its fact summary together with the source it was compiled from. Limits: publicly releasable cards only - gated or internal cards are never returned; each card is a single fact rather than analysis, and carries no recommendation. Ex: query_cards(keyword='ISCC'), query_cards(type='标准解读', region='欧盟').
