A Ship of Spices for an Official Post: Agarwood Accounts Under the Maritime Trade Office

Today we are not discussing how to select agarwood, but something further downstream: in the Southern Song, what could a ship of aromatics delivered to Quanzhou be exchanged for?

The answer: an official post.

I. Two numbers on the manifest that do not match

First, a string of figures.

In Li Dawei's Song-Yuan Quanzhou and Indian Ocean Civilization, a Champa tribute manifest is cited, recording aromatics shipped from Champa to Quanzhou in the 25th year of Shaoxing (1155): aromatics alone comprised seven kinds including agarwood, totaling 63,334 catties.

The entries are listed as follows: "The aromatics carried by convoy leader Wu Bing on behalf of Champa arrived at Quanzhou, including 24,035 catties of white frankincense, 80,290 catties of mixed frankincense, 237 catties of fuzi agarwood, 990 catties of agarwood, 92 catties 8 liang of agarwood heads, 205 catties of jianxiang heads, 301 catties of jianxiang and jiannan wood, and 1,780 catties of huangshu aromatics."

What do these eight items add up to?

White frankincense 24,035; mixed frankincense 80,290; fuzi agarwood 237; agarwood 990; agarwood heads 92.5; jianxiang heads 250; jianxiang 301; huangshu aromatics 1,780.

The total is 104,376.5 catties.

But the first sentence of the same passage states 63,334 catties.

The two figures differ by 41,042 catties.

I will not reconcile this discrepancy on behalf of the ancients. The original text simply presents both numbers: perhaps the classification criteria differ, perhaps some entries are subordinate to others, or perhaps the original simply offers no explanation. Readers doing the arithmetic themselves is more interesting than my guessing at an answer.

It should be noted that among these eight entries, "fuzi agarwood," "agarwood heads," "jianxiang heads," and "huangshu aromatics" are transcribed as in the original; I have not converted them to modern colloquial names—verifiability matters more than fluency.

II. Tax extraction and official purchase: how aromatics became money

Aromatics arriving in Quanzhou did not go directly to incense shops. They first passed through the Maritime Trade Office.

Tax extraction (choujie) was the proportional taking of goods, converted into cash and submitted to the court; official purchase (choumai) was the government buying an additional portion. The government took goods, merchants took cash, and the court took tax—this system turned aromatics into a fiscal line.

The same book records the official incentive as follows: "For every one million liang of frankincense extracted and purchased by supervisory officials of the Fujian and Guangdong maritime offices, one official rank is transferred."

One million liang of frankincense extracted and purchased earned a rank transfer. The grade was not low.

In the same chapter there is another provision for convoy leaders: "When convoy leaders of the various maritime trade offices can attract ships and extract goods, accumulating value of fifty thousand or one hundred thousand strings of cash, they shall be granted official posts of varying degrees."

A convoy leader was the person in charge of a fleet, not an ordinary merchant. If he attracted many ships, extracted much cargo, and accumulated value reaching fifty thousand or one hundred thousand strings, he could be granted an official post. The foreign merchant convoy leader Cai Jingfang, from the first year of Jianyan (1127) to the fourth year of Shaoxing (1134), attracted shipping cargo and collected interest money totaling 980,000 strings; he was granted the post of Chengxin Lang. Pu Luoxin of the Dashi country built a ship carrying frankincense to the Quanzhou Maritime Trade Office, with extracted value calculated at 300,000 strings; the court decreed that Pu Luoxin be granted the post of Chengxin Lang, with official robes, shoes, and a tablet.

Foreign merchants receiving Chinese official posts was not new; what was new was the scale of the numbers.

III. Why aromatics were worth buying with official posts

This was not simply "rare things are precious." In the Song dynasty, aromatics had three overlapping attributes.

First, scarcity. Sea transport meant supply fluctuated; one unfavorable monsoon could send prices jumping.

Second, function. Aromatics were not only for smelling; they were materials shared by sacrifice, banquets, medicine, and the fumigation of clothing. Demand did not fall to zero with economic conditions.

Third, organization. The official incentives above themselves show that this business was large enough to require the court to establish dedicated officials to manage it, and to turn extraction, purchase, reporting, and appointment into a set of procedures. Only things that could enter this procedure qualified as bulk commodities.

IV. What this account offers today's agarwood readers

This history is not presented to show off antiquity.

It reminds us of at least two things.

First, in ancient bulk aromatics trade, "incense" was never an isolated commodity; it was bound together with the tax system, official posts, and shipping cycles. To estimate the price of a piece of agarwood, you must first know which channel it traveled and under what system.

Second, the manifest itself is worth studying. That mismatched figure above—the eight items totaling more than forty-one thousand catties more than the first sentence's total—is precisely where the manifest is most valuable. A list that cannot even reconcile itself carries far more information than one that reconciles suspiciously well.

In our incense work, we have consistently printed the execution standard number on the back of packaging for the same reason: the number is an entry point for you to check yourself, not advertising copy for you to read. If it has a number, check it by the number; whether you can find it or not, report back to me, and I will write it out clearly, one by one.

V. A closing thought for today

Southern Song people exchanged a ship of incense for official posts. When we discuss incense today, we often discuss a price, whether it sinks, and how strong the aroma is.

Two eras, two sets of calculations, each with its own logic.

But one thing is common: any large business involving incense rests on a specific set of accounts. If you cannot see the accounts and only look at the incense, you may end up buying only the appearance of incense.

In the comments, tell us the execution standard number on the back of the packaging of the box of incense you have, and I will sort what can be verified and what cannot into two columns by standard number.
