In game it is examined as “A dark, thick, foul-smelling, tar-like substance.” Harralander tar is members-only, so a membership is needed to trade or use it. The base game value is 1 gp, which is what shops price from rather than what players pay.
The Grand Exchange lets one account buy 11,000 every 4 hours. That is a generous limit, so the market rather than the limit is usually what caps a position here. Filling it once costs about 77,000 gp at the 7 gp price recorded on 11 October 2026. The limit is per account and resets on a rolling 4-hour timer.
The 2% sale tax is rounded down, and at 7 gp it rounds to nothing — sales under 50 gp are untaxed, so a flip here keeps its whole margin.
High alchemy turns one Harralander tar into 1 gp. That is less than the 142 gp nature rune the cast costs, so alching Harralander tar always loses money.
Harralander tar sees about 62.6K trades a day, which makes it steadily traded — an order priced at the spread normally fills the same hour. That is roughly 6 times the 11,000 buy limit.
