Comparison

Sago or tapioca starch.

Tapioca comes from the cassava root and sago from the pith inside a palm trunk. They are sold into overlapping markets and they behave differently on hydration and in a finished product, so a formulation built on one does not simply accept the other.

Side by side.

Criterion	TapiocaFrom the cassava root. The volume starch, produced across Java and Sumatra.	SagoFrom the sago palm trunk. Concentrated in Papua and the eastern islands.
Source	A root crop harvested on a cycle of months, planted and replanted.	The pith of a palm that takes years to mature, much of it wild stands rather than plantation.
Supply reliability	Steady and large. Cassava is planted deliberately and processed at industrial scale.	Smaller and more variable, and concentrated a long way from container ports.
Behaviour in use	Well characterised across food manufacturing, with a large body of formulation experience behind it.	Different hydration and texture. A formulation written for tapioca has to be re-tested rather than swapped.
Price and availability	The cheaper and more available of the two, and the default for most industrial users.	Dearer and harder to source in quantity, which is why substitution runs in one direction.
Registered origin¹	No geographical indication in the Indonesian register for the starch.	Sago from the Lingga islands is registered, which gives a defined origin to contract on.
Logistics	Produced close to Javanese and Sumatran ports, so the inland leg is short.	The largest natural stands are in Papua, with an inter-island leg before the ocean one.

Which to choose.

You need volume, price and a known formulation: Tapioca.
You want the specific texture sago gives: Sago, and re-test the formulation rather than assuming a swap.
You need a verifiable origin claim: Sago from Lingga, which is registered.
An offer quotes sago at a tapioca price: Ask which plant. That gap is where the substitution lives.

Questions buyers ask.

Can I substitute one for the other?

Not silently. They hydrate differently and give a different texture, so a product built on tapioca will change if sago is dropped in. Reformulating deliberately is fine and it is a development project rather than a purchasing decision.

Which is easier to buy from Indonesia?

Tapioca, considerably. It is produced at industrial scale close to good ports. Sago comes from further east with longer domestic legs and smaller volumes, which shows up in both price and lead time.

Are both gluten free?

Neither plant contains gluten. Whether your finished product can carry the claim depends on the plant it was processed in and on your own market's rules, which makes it a supplier question rather than a botanical one.

Still deciding?

Tell us the application and the market. We will say which one your specification actually needs, and quote both if it is genuinely close.
