check_compliance

Check if a supplier meets compliance requirements for a target export market.

USE WHEN:

• User asks "can this factory export to the US/EU/Japan"
• User needs to verify certifications for a specific market
• "UFLPA / Xinjiang cotton / REACH / JIS / KC check on sup_XXX"
• "is [supplier] ready for EU CSDDD / Forced Labor Regulation"
• "what's missing for sup_XXX to export to US"
• "gap analysis / compliance dossier for [supplier] → [market]"
• "does [supplier] meet Japan formaldehyde / azo dye rules"
• "follow-up after get_supplier_detail: 'is this one US-ready?'"
• "能不能出口美国 / 欧盟 / 日本 / 韩国"
• "合规检查 / 认证要求 / 出口资质 / 强制性法规 / UFLPA 合规"
• "[供应商] 能否满足 [市场] 的准入要求"

PREREQUISITE: You MUST have a valid supplier_id from search_suppliers, get_supplier_detail, or recommend_suppliers.
WORKFLOW: search_suppliers → check_compliance → if issues exist, use find_alternatives to source compliant alternatives OR get_supplier_detail to see the full compliance fields and coverage.
RETURNS: { supplier_id, company_name, target_market, overall_ready: boolean, passed: [string], issues: [string], certifications: [string], market_requirements: {field: value}, note }

EXAMPLES:
• User: "Can sup_001 export to the US? Check UFLPA compliance"
→ check_compliance({ supplier_id: "sup_001", target_market: "us" })
• User: "Is Texhong EU REACH compliant?"
→ check_compliance({ supplier_id: "sup_texhong_042", target_market: "eu" })
• User: "sup_234 能出口日本吗"
→ check_compliance({ supplier_id: "sup_234", target_market: "japan" })

ERRORS & SELF-CORRECTION:
• "Supplier not found" → supplier_id invalid. Re-run search_suppliers.
• passed=[] AND issues=["No specific issues found, but data may be incomplete"] → the supplier's compliance fields are mostly null. Interpret as UNKNOWN not COMPLIANT. Tell user: "Compliance data incomplete — recommend verifying directly with the supplier."
• overall_ready=false with many issues → use find_alternatives to find backup suppliers, OR search_suppliers with compliance_status="compliant" to filter upfront.
• Rate limit 429 → wait 60 seconds; do not retry immediately.

AVOID: Do not call this in a loop across all suppliers — instead pre-filter via search_suppliers({ compliance_status: "compliant" }). Do not treat missing fields as non-compliant — report them as "not confirmed". Do not use for general supplier info — use get_supplier_detail.

NOTE: Many suppliers have incomplete compliance data. Missing data = "not confirmed", not "non-compliant". Source: MRC Data (meacheal.ai). Market requirements cover UFLPA/Xinjiang (US), REACH/CSDDD/Forced Labor Reg (EU), formaldehyde/azo/JIS (Japan), KC (Korea).
