Saturated Polyester Resin for Powder Coatings: India vs China vs Global Market

The clearest open-data signal is an import imbalance.

In calendar 2023, India imported 117.69 million kg of HS 390799 material, valued at US$271.19 million, according to UN Comtrade data displayed by the World Bank’s WITS portal.

India exported 19.821 million kg worth US$48.491 million. The arithmetic is a net import of 97.869 million kg and a trade deficit of US$222.696 million for the broader product basket.

China was the largest single supplier: US$94.545 million and 53.390 million kg. That equals 34.9% of India’s global HS 390799 import value and 45.4% of import quantity.

Thailand was second by value at US$40.119 million, followed by Korea at US$20.795 million, Chinese Taipei at US$18.440 million and the United States at US$18.287 million.

The mix shows both Asian scale supply and specialty-grade dependence.

Exports are a useful foothold, not proof of self-sufficiency.

India shipped US$48.491 million in 2023, led by the UAE (US$7.166 million), Bangladesh (US$4.999 million), Indonesia (US$4.948 million), Türkiye (US$2.986 million) and Vietnam (US$2.813 million).

These are logical nearby markets for qualified export-grade powder-resin systems, but the volume gap remains stark.

China’s advantage is ecosystem depth. Grand View Research estimates China’s powder-coating market at US$4.647 billion in 2022, projecting US$7.050 billion by 2030.

It is not an official production census, but it captures the downstream base that supports broad resin portfolios, multiple curing chemistries, pigment and effect suppliers, equipment makers and fast iteration between resin maker and powder formulator.

India is smaller but not marginal.

The same research publisher estimates India’s powder-coatings market at US$811.4 million in 2025 and identifies polyester as its largest resin segment, with 34.39% of 2025 revenue in that study.

Use that as a directional demand signal, not as tonnes of resin sold.

Appliances, metal furniture, electrical equipment, automotive components, architectural aluminium and general fabrication all create recurring demand for durable powder finishes.

Globally, saturated polyester resin is estimated at US$6.3 billion in 2026, rising toward US$7.9 billion by 2030 at 5.7% CAGR.

Asia Pacific represented 61.2% of 2023 revenue; powder coatings were the largest end use and solid resin the largest material segment.

Different research studies have different boundaries, so do not turn them into fake market-share math.

The durable conclusion is that powder is a major and growing outlet for solid saturated polyester, with Asia at its centre.

The market is moving from “a reliable standard flake” toward “a reliable formulation platform”. Indoor 50:50, 60:40 and 70:30 epoxy-polyester hybrids remain volume products.

Outdoor 93:7 polyester/TGIC systems remain important for weatherability.

But development is concentrating on TGIC-free HAA systems, superdurable exterior grades, lower-temperature or faster cure, thin-film flow, low-gloss control, metallic and bonded effects, and textures that remain consistent from batch to batch.

Energy is one commercial driver.

A resin-curative package that lowers bake temperature or shortens dwell can reduce oven energy and improve throughput—but judge it at actual metal temperature, part geometry, film build and completed-panel performance, not a brochure claim.

The same discipline applies to “superdurable”: evaluate the relevant weathering panel and customer specification, not a generic label.

Powder’s low- or zero-VOC advantage remains a major tailwind, but production still has dust, recovery, cleaning-loss, colour-change and exposure challenges.

The winning resin offer is therefore stable material plus processing guidance, colour-formulation compatibility and help resolving line-level defects.

There is no credible public, current market-share table for powder-coating-grade saturated polyester resin in India. Do not invent one.

Publicly visible India-based examples include Aditya Birla Chemicals,

which states it produces solid saturated polyester resins at Vilayat for powder-coating formulations alongside epoxy resin; Tough Color Resins, which markets hybrid saturated polyester grades; Advance Powdertech & Resins; and Kanoria Chembond.

These are active supplier examples, not a revenue ranking or endorsement.

Imported-grade distribution remains important. BalaChem identifies itself as the India partner for South Korea’s Inopol and offers hybrid and TGIC systems.

This is commercially useful for customers who need a qualified imported grade, but it also shows the opportunity for local substitutes that reproduce performance and provide faster technical support.

Globally, allnex’s CRYLCOAT portfolio is a recognised powder-resin reference.

The broader supplier set named in Grand View Research includes DSM, allnex, Arkema, IGM Resins, Mitsubishi Chemical Group, Polynt, Hexion, Evonik, BASF, Ashland and Sika.

In China, the China Coatings Industry Association’s powder-coating branch publishes industry rankings,

while specialist producers publicly offer TGIC, HAA, hybrid and low-temperature polyester systems.

Treat all supplier lists as a qualification starting point, not a conclusion about size or approval status.

A powder plant does not buy “polyester”; it buys a particular grade that must process the same way in a given extruder, accept a pigment package, hit a cure window and pass adhesion, impact, gloss and weathering expectations.

Establishing local versions of high-rotation standard grades builds volume and learning.

Reproducing specialised outdoor, low-bake, matt and effect grades requires stronger analytical, application and customer-validation capability.

The next gap is feedstock and process integration. Polyester economics are linked to diacids/anhydrides, glycols, catalysts, energy, freight, currency and inventory.

China’s edge comes from a broad upstream and downstream base, not one resin reactor.

India should reduce exposure through dual-qualified feedstocks, local logistics, disciplined inventory and long-term demand signals—not by assuming import substitution is automatically a technical solution.

The most underappreciated gap is colour collaboration. Resin, pigment, aluminium effect, filler, flow additive and extrusion settings interact.

A local resin supplier that helps a colour maker hit shade, gloss and recoat consistency creates far more value than one offering a generic flake at a small discount.

The proof should be a controlled formulation file with panel data, not an unverifiable performance promise.

First, standardise. Choose the high-turn grades in your target customer base and lock tight windows for acid value, Tg, melt viscosity, colour and gel time.

Run comparable pilot and commercial batches with the customer’s own pigment, additive and extrusion process.

A claimed equivalent should be tied to a named benchmark and a documented test method.

Second, differentiate collaboratively.

Build joint development cells with powder coaters, pigment/effect suppliers and applicators around HAA/TGIC-free, low-bake, superdurable, matt, texture and bonded-metallic systems.

The output should be a qualified package: resin grade, curative, pigment/additive recipe range, extrusion window, bake schedule and panel-performance target.

That is much harder to commoditise than a generic resin data sheet.

Third, export evidence. India’s 2023 HS 390799 exports already have footholds in the UAE, Bangladesh, Indonesia, Türkiye and Vietnam.

Start where freight and service are manageable, then win repeat orders with consistent COA, English SDS/TDS, batch traceability, required market-compliance checks and end-use-relevant panels.

Export growth should follow approved formulations, not precede them.

A resin switch should be a controlled technical qualification, not simply a purchasing action.

Start by naming the system—hybrid, TGIC, HAA, urethane or another chemistry—then define resin:curative ratio, shade/effect class, gloss, film build, substrate, pretreatment, metal temperature, dwell and performance standard.

Without that context, two TDS sheets cannot be fairly compared.

Run a laboratory screen and a production-representative trial.

Record extrusion torque and temperature, chip quality, grindability, particle-size distribution, fluidisation, electrostatic application, gel time, gloss, appearance, impact, bend, cross-hatch adhesion, humidity/corrosion and weathering where required.

Reclaim behaviour and colour-change cleaning can be more valuable than a small raw-material saving.

Finally, isolate the cause when a panel fails. The defect may come from resin, curative, pigment, additive, filler, extrusion temperature, contamination or application.

The supplier who helps find the variable is substantially more valuable than one who only supplies material.

China will remain the benchmark for breadth and scale.

India should not claim the gap has vanished: the 2023 HS 390799 trade balance still points to material import exposure, and Chinese supply remains a large part of that basket.

Yet India’s growing powder demand, local producers, broad downstream manufacturing and nearby export markets make a stronger position practical.

The winning Indian proposition is not “made locally” alone.

It is stable resin chemistry, qualified alternate feedstocks, fast technical response, co-developed colour/formulation packages and proof on the coated part.

Resin makers need application and analytical investment; pigment and powder makers need to involve suppliers earlier and share enough process information to qualify performance properly.

That is how India can move from importing a broad basket of polyester products to exporting more approved, higher-value powder-coating solutions: not by chasing every grade, but by becoming exceptionally dependable in the grades and formulations customers repeatedly need.
