The parts the data misses

Three demand and revenue pools deserve separate treatment because they are systematically undercounted by headline market figures — and all three push the industry toward the premium end of the ladder.

Trading and merchant volume — revenue with no factory behind it

A characteristic of this sector that market studies never capture is that producers routinely trade material alongside what they manufacture: buying third-party powder, qualifying it, repackaging it under their own quality system, and selling it into their own customer relationships. Accent Microcell, for example, reported total sales volume of roughly 15,000 metric tonnes in FY26 against installed capacity of about 9,200 MTPA — approximately 70% manufactured and 30% traded.

This is not a criticism; it is a rational response to being capacity-constrained in a market where losing a qualified customer is expensive. But it matters analytically for two reasons. It inflates revenue relative to manufacturing capability, and it dilutes margin, because traded material earns a distribution spread rather than a conversion margin. A company whose traded share is falling as new capacity commissions will show margin expansion that has nothing to do with pricing.

Co-processing and continuous manufacturing — the premium tailwind

The second uncounted pool is the migration of value into engineered systems. Market studies size "microcrystalline cellulose" as a material; they do not capture the fact that an increasing share of MCC is sold inside a co-processed system at a materially higher realisation. Recent product launches aimed explicitly at continuous direct compression are the visible edge of this.

What makes it a rising tailwind is that it is driven by the very forces that constrain conventional demand: regulators pushing continuous manufacturing, formulators avoiding water and heat, and plants being designed for fewer unit operations. The headwind on the old process is the mechanism generating this tailwind.

Direct compression's growing share of new formulations, and fastest growth at the hard end of the grade ladder
Figure 8.1 — Direct compression keeps taking share of new oral solid formulations (left), and the fastest volume growth sits at the hard end of the grade ladder (right). Neither trend is visible in a chart of total MCC tonnage. Indicative; directional rather than precise.

The non-pharmaceutical spillover — the same powder, a very different sale

The third pool is food, nutraceutical, bakery, dairy and cosmetic demand. Physically this is often the same material from the same line. Commercially it is a different business: lower specification, lower price, far shorter sales cycle, and almost no switching cost. Its virtue is that it is large, growing with clean-label formulation trends, and uncorrelated with pharmaceutical destocking cycles — so it keeps a plant loaded.

Its vice is that it is competitive on price and offers no protection. A producer whose mix drifts toward food and nutraceutical volume is buying revenue stability at the cost of margin and defensibility. Reading a company's disclosed application mix is therefore one of the more revealing things you can do with its annual report.

Table 8.1 — The same product sold two ways. The physical good is close to identical; the commercial characteristics are opposite. This is the closest analogue in this industry to the distinction between a contracted and a spot business — and it is why application mix, not tonnage, is the number to watch.

The excipient value chain — and where the margin sits
Dissolving pulp
eucalyptus, pine, cotton linter, bamboo · imported, commodity priced, <40–60% of COGS
Excipient maker
hydrolysis, spray drying, milling · where particle architecture and the dossier are created
Formulator / CDMO
blending, granulation, compression · buys on qualification, not on price alone
Patient
one tablet, twice daily, for years · never sees any of it — which is the entire point

Figure 8.2 — The value chain and where the margin sits. Only one box in this chain converts a commodity into a specification — and correspondingly the only one carrying a regulatory liability for it. Accent and Sigachi sit in box two; Oji's purchase of Chemfield was box one buying box two.

A subtle but important distinction

Backward integration into pulp does not move a producer up the ladder — it moves them down it, toward commodity economics, in exchange for input security. Forward integration into co-processed systems and derivatives moves them up. When Oji Holdings, a Japanese pulp group, acquired a stake in an Indian MCC producer in March 2025 and described the logic as a "tree to tablet" chain, that was the pulp business buying its way up into specification — the same move, viewed from the other end of the chain.
