How to Verify an Indonesian Green Coffee Supplier

Published June 2026 · By Willkin Green Coffee (PT Global Wills Sejahtera)

Indonesia is the world's fourth-largest coffee producer, but the export landscape includes hundreds of intermediaries, brokers, and trading companies alongside genuine licensed exporters. For an importer, choosing the wrong supplier can mean quality failures, customs delays, or complete loss of payment. This guide explains the verification steps every buyer should complete before placing an order.

1. Confirm the Legal Entity

Every legitimate Indonesian coffee exporter operates as a registered PT (Perseroan Terbatas) — the Indonesian equivalent of a limited company. Ask for the following documents:

DocumentIssued ByWhat It Confirms
NIB (Nomor Induk Berusaha)OSS / Ministry of InvestmentBusiness registration number; required since 2018
Angka Pengenal Ekspor (APE/APEU)Ministry of TradeLicense to export agricultural products
NPWP (Tax ID)Directorate General of TaxesActive taxpayer status
Akta PendirianNotary + Ministry of LawCompany deed — confirms legal founding and ownership
SIUP / NIB PerdaganganMinistry of TradeTrade business license
Phytosanitary CertificateBARANTAN (per shipment)Plant health clearance for each export lot

Cross-check the company name on the NIB against the PT name on shipping documents. Mismatches are a common sign of a broker acting as an exporter.

2. Verify Export Certifications

Depending on your destination market, specific certifications may be legally required or commercially expected:

CertificationRequired ForIssuing Body
Organic (USDA NOP)US organic labelAccredited certifier (e.g., Control Union, IFOAM)
EU Organic (EU 2018/848)EU organic labelEU-accredited certifier
Rainforest Alliance / UTZSustainability claimsRainforest Alliance
Fair TradeFair trade retail positioningFairtrade International
SNI Grade 1Premium B2B green coffeeBSNI (Indonesian National Standard)
COO (Certificate of Origin)Customs in most marketsIndonesian Chamber of Commerce (KADIN)

Always request the certificate number and verify it directly on the certifying body's website. Never accept a certificate image without cross-checking the validity date and scope.

3. Check Third-Party Business Registries

Indonesian exporters listed on official trade directories have been partially vetted by government agencies:

4. Request a Sample Before the Full Order

No amount of document verification replaces a physical sample evaluation. A credible supplier will always offer:

Sample TypeWhat to EvaluateStandard
Green bean sample (300–500g)Moisture, defect count, screen sizeSNI 01-2907-2008
Roasted sample (optional)Cup profile, off-flavorsSCA cupping protocol
Lab analysis reportMoisture %, density, defect %Supplier or third-party lab
Willkin standard: All samples ship with a moisture/defect data sheet. Typical Gayo Grade 1: moisture 11–12.5%, defects <11 per 300g, screen size 15+.

5. Assess Communication and Response Time

Response time is a proxy for operational capacity. A supplier handling real export volumes typically responds to detailed RFQs within 24–48 hours. Vague answers to specific questions about lot size, harvest date, processing method, or current stock availability are warning signs.

6. Red Flags to Avoid

No NIB or APE — cannot legally export without these
Price significantly below FOB Belawan market rate — likely blended or misrepresented origin
No physical address — broker without warehouse or processing capacity
Refuses to provide sample before full order — unable to match sample to bulk
Certificates with expired validity dates or no certificate number
Payment terms: 100% upfront with no escrow or LC option for first order
