Learning how to choose a green coffee supplier comes down to a few checkable things: verified quality, traceability, reliable logistics, and a team that actually answers the phone. Intercontinental Coffee Trading (ICT Coffee), a San Diego-based specialty green coffee importer serving roasters across the USA and Canada, works with roasters at every scale — and the questions below are the same ones our own buyers ask when evaluating a supply chain.
Start With Verified Quality, Not Marketing Language
Any supplier can call a coffee “specialty.” The ones worth working with can prove it. The Specialty Coffee Association defines specialty grade by measurable criteria, and a credible supplier evaluates lots against that standard rather than against a sales pitch. When you’re choosing a green coffee supplier, ask how they verify quality before a lot reaches their inventory.
The strongest answer involves a licensed Q Grader. A Q Grader is a certified coffee evaluator — the industry’s calibrated palate — and a supplier with Q Graders on staff is scoring coffee to a recognized protocol, not guessing. ICT’s Q Grader evaluation process applies that standard to every lot before it’s offered.
Demand Real Traceability
Traceability is the difference between knowing a coffee is “from Colombia” and knowing the farm, region, altitude, variety, and processing behind it. That detail does two things for a roaster: it predicts how the coffee will cup and roast, and it gives you a story to tell customers who increasingly want to know where their coffee comes from.
A supplier that visits farms and documents those relationships can back up its traceability claims. Ask whether they actually source at origin or simply buy from brokers. ICT documents its direct work through farm visit reports, and the difference shows up in how much they can tell you about a given lot on the live inventory.
Check Defect Standards and Cup Scores
Two numbers separate genuine specialty from commercial coffee dressed up with a label: defect count and cup score. Under the SCA’s green coffee classification, specialty-grade coffee carries zero primary defects and no more than five full secondary defects in a 350g sample, and a specialty cup scores 80 or higher on the 100-point scale.
A reliable supplier provides both numbers on request and can explain how they were measured. If a supplier can’t tell you the cup score of a lot they’re calling specialty, that’s a signal. ICT’s guide to questions to ask green coffee suppliers covers exactly what to request before you buy.

Test Logistics Before You Depend on Them
Quality means little if the coffee can’t reach your roastery on time. When choosing a green coffee supplier, look at warehouse locations, typical lead times, and how the supplier handles partial pickups of a larger commitment. A supplier with regional warehouses can get coffee to you faster and let you draw down a position over weeks instead of taking delivery all at once.
Ask about storage conditions too — green coffee ages, and a supplier that warehouses coffee in temperature-stable, food-grade conditions protects the quality you paid for. ICT outlines its national distribution in its logistics overview, and roasters on either coast can see the practical impact through its East and West Coast importing operations.
Weigh Supply Chain Stability
A supplier is only as reliable as its ability to fulfill orders year after year. Financial stability, buying power, and depth of origin relationships all determine whether your supplier can still deliver when a harvest comes up short or freight costs spike. For a growing roaster, switching suppliers mid-season because the last one ran out is an expensive disruption.
Ask how long the supplier has been operating, how broad their origin network is, and whether they’re backed by a larger group. ICT has imported since 2009, sources from more than 30 origins, and is part of the Hamburg Coffee Company Group — depth that matters most when the market gets tight, as covered in ICT’s look at the role importers play as wholesale suppliers.
Judge the Relationship
The best suppliers treat a small roaster the same way they treat a large one. You want a real person who answers questions, helps you evaluate samples, and flags new arrivals that fit your menu — not a ticketing system. A supplier’s sample program is a good early test: an importer confident in its coffee makes it easy to try before you buy. ICT offers up to four free samples and explains the process in its sample request guide.
Run the Cupping Yourself
No amount of paperwork replaces tasting the coffee. Before you commit to a supplier, request samples and cup them blind against your current lots. A supplier worth keeping will welcome that scrutiny and may even host cupping sessions. ICT runs regular cuppings — see the cupping events page — because confident sourcing holds up in the cup, not just on a spec sheet.
Frequently Asked Questions About Choosing a Green Coffee Supplier
What’s the most important factor when choosing a green coffee supplier?
Verified quality. A supplier should be able to show you a cup score and defect count measured against the SCA specialty standard, ideally by a licensed Q Grader. Everything else — price, logistics, relationship — matters, but it starts with proof the coffee is what they say it is.
How do I start working with a green coffee importer?
Request samples first. Most reputable importers, including ICT, offer free samples so you can cup the coffee before committing. From there you discuss minimums, pricing, and logistics. Getting started usually takes a sample request and a conversation, not a long contract.
Do I need a large account to get good service?
No. The right supplier treats small roasters with the same attention as large ones. ICT works with roasters from startups buying a few bags to multi-location brands, and offers the same Q Grader verification and sample access to each.
How can I verify a supplier’s quality claims?
Ask for the cup score, defect count, harvest date, and the evaluating Q Grader’s credentials. Registered Q Graders appear in the Coffee Quality Institute’s database. Then cup the samples yourself. A supplier that can’t or won’t provide those details hasn’t earned your business.
