**Yes — grade B teak is safe and structurally sound for export furniture when it is properly kiln-dried and matched to the right use. The gap between grade A and grade B is mostly cosmetic: more sapwood, visible knots, and color variation, not a collapse in strength. Specify grade to the application, not to prestige.**
What actually separates grade B teak from grade A?
Both grades come from the same species, Tectona grandis — the jati that Jepara workshops have milled for generations. The split is about where a board sits in the log and how it looks, not whether it is “real” teak.
Grade A is cut from the mature heartwood at the center of the trunk: even honey-brown color, tight grain, few knots, and the highest natural oil content. Grade B pulls in more of the outer wood — lighter sapwood streaks, small sound knots, and more tone variation from board to board.
Here is the practical breakdown:
| Attribute | Grade A teak | Grade B teak |
|---|---|---|
| Source in log | Inner heartwood | Heartwood plus some sapwood |
| Color | Uniform golden-brown | Mixed tones, sapwood streaks |
| Knots | Few to none | Small, sound knots allowed |
| Natural oil | Highest | Good, slightly lower in sapwood |
| Typical use | Showpiece, flagship indoor/outdoor | Volume orders, painted/rustic, contract |
| Indicative cost gap | Baseline | Roughly 15–30% lower* |

For buyers who want the honest middle path, sourcing grade B teak furniture is often the smartest way to hit a hospitality budget without dropping to a weaker species like acacia or eucalyptus.
Is grade B teak actually strong enough for export furniture?
Short answer: yes. Strength in teak comes from the species’ dense fiber and interlocked grain, and grade B shares both. A small sound knot or a sapwood streak does not meaningfully weaken a chair leg or a table apron.
What does matter is moisture. Kiln-drying to a moisture content of roughly 8–12% is the real safety lever — not the cosmetic grade. Wood that ships too wet will move, crack, and split in a dry European or Middle Eastern interior no matter how flawless the surface looked in Jepara.
The one honest caveat: sapwood is less naturally rot-resistant than heartwood. For furniture that sits in full sun and rain year-round, higher heartwood content earns its premium. For covered terraces, indoor use, and painted pieces, grade B performs for many years with normal care. No exporter can promise an exact lifespan — climate, finish, and maintenance decide that.
Where does grade B teak perform best?
Match the grade to the job. Grade B shines wherever character or budget matters more than a flawless uniform face.
- Indoor case goods — wardrobes, sideboards, bed frames where knots read as character
- Painted and lacquered pieces — the finish hides tone variation entirely
- Rustic and reclaimed-look collections — sapwood and knots are the aesthetic
- Contract and hospitality volume — hotels furnishing dozens of rooms at once
- Covered outdoor — terraces, verandas, shaded restaurant seating
Where to lean grade A instead:
- Fully exposed poolside and garden furniture in wet climates
- Flagship showroom hero pieces sold on visual perfection
- Large clear tabletops where one uniform face is the selling point
What are the real value trade-offs?
The decision is rarely “safe vs unsafe.” It is “what am I paying for, and does my buyer notice?”
| Priority | Choose grade B | Choose grade A |
|---|---|---|
| Tight FOB budget | Yes | |
| Painted or distressed finish | Yes | |
| Natural uniform show surface | Yes | |
| Year-round full sun and rain | Yes | |
| Maximum pieces per container | Yes | |
| Resale on a “premium teak” story | Yes |
A mixed A/B container is common and sensible: grade A on the pieces buyers inspect up close, grade B on painted or lower-visibility items. Because Indonesian teak is quoted per piece and per spec, your exporter can cube a container that blends grades to hit both your look and your landed cost — the USD figures only move with construction, finish, and how the container cubes out.
What should importers specify to keep grade B safe?
Grade is only one line on a spec sheet. These clauses protect you more than the grade label alone:
- Moisture content — written as 8–12% kiln-dried, never “air-dried”
- Joinery — mortise-and-tenon or dowel, glued and pinned, not stapled
- Sapwood limit — for example, sapwood not to exceed a set percentage of the visible face
- Knot cap — sound knots only, under a stated diameter
- Finish system — oil, matte PU, or paint, stated per item
- Photo approval — pre-shipment images of the actual production run
Those six lines catch far more failures than obsessing over grade ever will.
Does grade B teak still need SVLK to leave Indonesia?
Yes — grade has nothing to do with legality. Every teak export from Indonesia, grade A or grade B, must move under SVLK (Sistem Verifikasi Legalitas Kayu), the national timber legality assurance system that has been compulsory for timber-industry operators since January 2013. Since 1 January 2015, all wooden furniture except bamboo requires a V-Legal Document to export.
Teak is explicitly inside SVLK scope as a plantation timber, and Indonesia was the first country in the world to issue FLEGT licences, starting November 2016 — a FLEGT-licensed shipment meets the EU Timber Regulation without extra importer due diligence. For EU-bound buyers, the newer EU Deforestation Regulation (EUDR, Regulation 2023/1115) adds geolocation and deforestation-free proof on top of legality, with full application phasing in around end-2026 into a 2027 concern. Grade B is as eligible for all of this paperwork as grade A; documents are prepared, but acceptance always rests with the authorities.
Frequently Asked Questions
Does grade B teak crack more easily than grade A during shipping?
Not because of the grade. Cracking in transit is almost always a moisture problem, not a cosmetic one. A grade B piece kiln-dried to 8–12% and joined properly travels as safely as grade A. Insist on a written moisture spec and sealed end-grain; that protects the piece far more than heartwood purity ever does.
Can I mix grade A and grade B in one export container?
Yes, and many hospitality buyers do exactly that. A blended container puts grade A on close-inspection or fully exposed pieces and grade B on painted, indoor, or lower-visibility items. Because Indonesian teak is quoted per piece and per spec, your exporter cubes the container to hit both your visual standard and your landed cost.
Is grade B teak suitable for outdoor furniture?
For covered or shaded outdoor use — terraces, verandas, restaurant patios — yes, with proper finishing and regular care. For furniture in full sun and rain year-round, higher heartwood content resists rot better, so grade A or a heartwood-heavy A/B mix is the safer call. No exporter can guarantee an exact outdoor lifespan; climate, finish, and upkeep decide it.
