The 2026 Indonesia robusta coffee price ranges from $3,900 to $5,100 per metric ton FOB Belawan, depending on origin, sub-grade, and defect count, according to Indonesia Specialty Coffee’s May 2026 wholesale catalogue. EK1 Grade 1 lots with a defect ceiling of 11 anchor the premium tier, while EK1 Grade 4b lots at 61–80 defects open up the budget end for high-volume blenders.
This guide breaks down the current Indonesian robusta coffee price by origin and sub-grade, clears up a common market misunderstanding about EK1 grading, covers defect specs and shipping, and shows roasters and importers how to order directly from ISC’s Medan facility.
Clearing Up a Common Misunderstanding: There Is No “EK2”
Before diving into prices, one point needs clarifying. A widespread misunderstanding in the market is that Indonesian Robusta is split between “EK1” and “EK2” grades. That distinction does not exist.
The correct grading is EK1 Grade 1, EK1 Grade 2, EK1 Grade 3, EK1 Grade 4a, EK1 Grade 4b, and so on. EK1 is the umbrella export quality designation; the Grade number (1 through 4b) refers to the defect count within that export standard.
The term “EK” comes from the Dutch phrase “Eerst Kwaliteit”, which translates to “first quality”, a legacy from the Dutch colonial coffee trade that stuck in Indonesian export terminology. So when you see “EK1 Grade 2” on a contract, it means “first quality export, sub-grade 2 by defect count”, not a separate EK2 category.
Throughout this guide, all prices and specs use the correct EK1 Grade 1 / Grade 2 / Grade 3 / Grade 4 terminology.

Lampung Robusta Green Coffee Beans
For buyers comparing offers across Indonesian Robusta suppliers, the Indonesian Robusta coffee price spread in ISC’s May 2026 catalogue covers six clear tiers, from premium Bali Kintamani down to EK1 Grade 4b lots aimed at blenders.
| Tier | Example Lot | Defect (per 300g) | FOB Belawan |
|---|---|---|---|
| Premium EK1 Grade 1 | Bali Kintamani Robusta ELB 350BC | ≤11 | $5,100 / MT |
| Standard EK1 Grade 1 | Sumatra Robusta ELB 350 BC Grade 1 | ≤11 | $4,400 / MT |
| EK1 Grade 2 | Lampung ELB 350 BC | 12–25 | $4,300 / MT |
| EK1 Grade 3 | Sumatra Robusta ELB 400 BC Grade 3 | 26–44 | $4,200 / MT |
| EK1 Grade 4a (60 Defects) | Sumatra Robusta EK1 60 Defects | 46–60 | $3,950 / MT |
| EK1 Grade 4b (80 Defects) | Sumatra Robusta EK1 80 Defects | 61–80 | $3,900 / MT |
The premium tier sits roughly 30 percent above the budget EK1 Grade 4b lots, and the standard EK1 Grade 1 to EK1 Grade 2 gap typically runs $100 to $300 per MT.
How EK1 Sub-Grades Affect the Indonesian Robusta Coffee Price
In Indonesian Robusta export trade, EK1 (Ekspor 1, derived from “Eerst Kwaliteit”) is the standard export designation, and sub-grades within EK1 follow the SNI 01-2907-2008 defect classification:
- EK1 Grade 1 = Mutu 1, maximum 11 defects per 300g
- EK1 Grade 2 = Mutu 2, 12 to 25 defects per 300g
- EK1 Grade 3 = Mutu 3, 26 to 44 defects per 300g
- EK1 Grade 4a = Mutu 4a, 45 to 60 defects per 300g
- EK1 Grade 4b = Mutu 4b, 61 to 80 defects per 300g
All EK1 sub-grades ship at moisture below 13 percent. Screen size typically falls between 15 and 19 for Grade 1 and Grade 2 lots, with Grade 3 and Grade 4 lots widening to 13–19.
A quick supplier note: ISC’s catalogue labels some Sumatra lots as “EK1 45/60/80 Defects”, these correspond to EK1 Grade 3, Grade 4a, and Grade 4b respectively, sold at lower price points for blend-grade buyers. The “EK1” prefix is correct on all of them; the number after refers to the defect ceiling within the EK1 export standard.
Pricing by Origin
The Indonesian robusta coffee price also varies by growing region. ISC ships Robusta from four main origins: Lampung (southern Sumatra), Sidikalang (Dairi, North Sumatra), broader Sumatra ELB lots, and Bali Kintamani.
| Origin | Grade | Defect | FOB Belawan |
|---|---|---|---|
| Lampung | EK1 Grade 2 (ELB 350 BC) | 12–25 | $4,300 / MT |
| Lampung | EK1 Grade 2 | 12–25 | $4,100 / MT |
| Lampung | EK1 Grade 3 (ELB 450 BC) | 26–45 | $4,250 / MT |
| Lampung | EK1 Grade 3 | 26–45 | $4,000 / MT |
| Sidikalang | EK1 Grade 2 | 12–25 | $4,100 / MT |
| Sidikalang | EK1 Grade 3 | 26–45 | $4,000 / MT |
| Sumatra ELB | EK1 Grade 1 (350 BC) | ≤11 | $4,400 / MT |
| Sumatra ELB | EK1 Grade 2 (350 BC) | 12–25 | $4,300 / MT |
| Bali Kintamani | EK1 Grade 1 (Robusta ELB 350BC) | ≤11 | $5,100 / MT |
For roasters chasing a chocolate-forward cup with low brightness, Bali Kintamani Robusta from Pupuan (450–700 masl) carries a clear premium. For volume buyers building dark espresso blends, Lampung EK1 Grade 2 and Sidikalang EK1 Grade 2 deliver classic full-body Robusta character at the lowest per-MT rates. ISC’s Robusta Lampung product page carries the full spec sheet, and the roasted Robusta Lampung page shows the post-roast option.
EK1 Grade 1 vs EK1 Grade 2 Compared
Within the EK1 export standard, the Indonesian robusta coffee price gap between Grade 1 and Grade 2 typically runs $100 to $300 per metric ton, depending on origin.
- Sumatra Robusta ELB 350 BC: EK1 Grade 1 (defect ≤11) at $4,400/MT versus EK1 Grade 2 (defect 12–25) at $4,300/MT — a $100/MT spread.
- Lampung: True EK1 Grade 1 lots stay limited season to season; ELB 350 BC at $4,300/MT serves the cleaner end of EK1 Grade 2, while standard EK1 Grade 2 at $4,100/MT covers the broader tier — a $200/MT spread within Grade 2.
- Bali Kintamani: Premium EK1 Grade 1 at $5,100/MT carries no direct EK1 Grade 2 equivalent in ISC’s current catalogue.
For roasters running cafe espresso programs that need consistent cup clarity, EK1 Grade 1 is usually worth the premium. For dark roast retail and high-volume house blends, EK1 Grade 2 delivers most of the body at a tighter cost ceiling.
Defect Specs, Moisture, and Screen Size
Defect counts drive most of the Indonesian robusta coffee price variance. ISC’s catalogue holds the following SNI-aligned specs across the EK1 sub-grades:
- EK1 Grade 1: Defect ≤11, Screen Size 15–19, Moisture max 13%
- EK1 Grade 2: Defect 12–25, Screen Size 15–19, Moisture max 13%
- EK1 Grade 3: Defect 26–45, Screen Size 15–19 (Lampung, Sidikalang) or 13–19 (Sumatra defect-labelled lots), Moisture max 13%
- EK1 Grade 4a (Sumatra “EK1 60”): Defect 46–60, Screen Size 13–19, Moisture max 13%
- EK1 Grade 4b (Sumatra “EK1 80”): Defect 61–80, Screen Size 13–19, Moisture max 13%
Roasters new to Indonesian Robusta should note that defects in Robusta are weighted differently from Arabica under SNI; black beans, sour beans, and stones each count as a full defect, so a 25-defect EK1 Grade 2 lot can still cup clean if the defects skew toward minor categories.
FOB Terms, MOQ, and How to Order
ISC’s default trade term is FOB Belawan, meaning the Indonesian robusta coffee price covers all costs through loading at Belawan Port in North Sumatra. Beyond that point, ocean freight and marine insurance fall to the buyer.
| MOQ Tier | Quantity | Best Suited For |
|---|---|---|
| Sample | 1 kg | Cupping evaluation, R&D |
| Microlot | 60 kg | Small roasters, single-origin runs |
| Wholesale | 350 kg | Mid-size roasteries, cafe chains |
| Container | 9 MT+ | Importers, distributors |
For example, a 9 MT container of Sumatra Robusta EK1 Grade 4a (60-defect) at $3,950/MT works out to roughly $35,550 FOB Belawan, before ocean freight. Container buyers usually negotiate CIF terms directly with ISC. Sample and wholesale orders go through the ISC contact page or the wholesale pricelist.
Seasonal Availability
The main Indonesian Robusta harvest runs May through September, with Lampung and Sumatra peaking in June and July. For roasters tracking the Indonesian robusta coffee price across the year, the deepest stocks and sharpest rates typically land between August and November, just after new-crop grading is finalised at the Medan facility. Past-crop Robusta remains available year-round at a 5 to 10 percent discount.
Frequently Asked Questions
What is the current Indonesian robusta coffee price per kg?
The 2026 Indonesia robusta coffee price from ISC starts at $3.90 per kg FOB Belawan for EK1 Grade 4b (80-defect) lots and climbs to $5.10 per kg for premium Bali Kintamani Robusta ELB 350BC (EK1 Grade 1). Standard Lampung EK1 Grade 2 sits at $4.10 per kg, and Sumatra Robusta ELB 350 BC EK1 Grade 1 lands at $4.40 per kg.
Is there a difference between EK1 and EK2 Robusta?
There is no “EK2” grade. This is a common market misunderstanding. EK1 is the umbrella export quality designation (from the Dutch “Eerst Kwaliteit,” meaning “first quality”), and within EK1, there are sub-grades: EK1 Grade 1, EK1 Grade 2, EK1 Grade 3, EK1 Grade 4a, and EK1 Grade 4b. The sub-grade is determined by defect count per 300g under SNI 01-2907-2008. So a contract should specify, for example, “EK1 Grade 2” — not “EK2.”
What is the difference between EK1 Grade 1 and EK1 Grade 2?
EK1 Grade 1 (formerly Mutu 1 under SNI 01-2907-2008) has a defect ceiling of 11 per 300g. EK1 Grade 2 (Mutu 2) allows 12 to 25 defects. Grade 1 cups cleaner with less off-flavor risk; Grade 2 delivers a similar body with a slightly more earthy edge at a $100 to $300 per MT discount.
Which origin offers the best value for blends?
For high-volume espresso blends, Lampung EK1 Grade 2 at $4,100/MT FOB Belawan typically delivers the best body-per-dollar ratio. For premium Robusta in single-origin espresso, Bali Kintamani Robusta ELB 350BC (EK1 Grade 1) at $5,100/MT brings cleaner chocolate notes thanks to its 450–700 masl volcanic terroir.
What is the moisture and screen size spec?
All ISC Robusta lots ship at a maximum of 13 percent moisture. Screen sizes vary by sub-grade: EK1 Grade 1 and EK1 Grade 2 lots (Lampung, Sidikalang, Sumatra ELB) ship at 15 to 19. Lampung ELB 450 BC carries a slightly tighter 14 to 18 screen. Sumatra EK1 Grade 3 / 4a / 4b lots (labelled as “EK1 45/60/80”) open to 13 to 19. Bali Kintamani Robusta EK1 Grade 1 specifies triage at a maximum of 6 to 8 percent on its spec sheet.
What is the MOQ for a Robusta order?
ISC accepts 1 kg samples, 60 kg microlots, 350 kg wholesale orders, and 9 MT container loads. Container buyers receive a custom per-MT quote and can negotiate CIF at destination through ISC’s Medan-based export team.
