How much does lactide cost? The answer depends far more on the specification than on a single posted price. Lactide is the cyclic dimer made from lactic acid, and its isomer, purity, moisture limit, batch testing, package size, and delivery terms can change the final purchase cost substantially.
Catalog pricing is useful for screening suppliers, but it is rarely a reliable proxy for production-scale lactide pricing. A small research pack may cost several thousand dollars per kilogram, while a qualified bulk order is quoted against a detailed specification.
We supplies L-lactide, D-lactide, and DL-lactide for laboratory, industrial, and medical-material applications. In this post we will explain the current catalog benchmarks, the cost drivers behind a quotation, and the information needed to compare offers on equal terms.

What Is the Current Price of Lactide?
Public catalog prices show why buyers should avoid treating one lactide price as a market-wide benchmark. As of August 2026, TCI America lists L-(-)-lactide at $93 for 25 g and $557 for 250 g, both at greater than 98% purity.
That works out to about $3,720 per kilogram for the 25 g pack and about $2,228 per kilogram for the 250 g pack. The material is the same listed isomer, but the larger package cuts the catalog unit cost by about 40%.
DL-lactide can follow a different price path. A May 2026 Spectrum listing for TCI DL-lactide showed $112.40 for 25 g and $387.65 for 100 g, which illustrates how isomer availability, package size, and supplier inventory can change a comparison.
| Catalog example | Package size | Listed price | Approximate price per kilogram |
|---|---|---|---|
| TCI America L-(-)-lactide, greater than 98% purity | 25 g | $93.00 | $3,720 |
| TCI America L-(-)-lactide, greater than 98% purity | 250 g | $557.00 | $2,228 |
| TCI DL-lactide catalog listing | 25 g | $112.40 | $4,496 |
| TCI DL-lactide catalog listing | 100 g | $387.65 | $3,877 |
These are research-scale list prices, not a promised bulk rate. Use them to set a budget range for early formulation work, then request a project quotation for pilot or commercial demand.

What Factors Affect Lactide Cost?
Lactide production begins with lactic acid, but the final cost reflects the work needed to create a consistent monomer for polymerization. Buyers who define the technical requirements before requesting pricing receive quotes that are easier to compare and less likely to change after qualification.
Lactide Type or Isomer
The specific isomer you choose has a big impact on your lactide pricing. L-lactide, D-lactide, DL-lactide, and meso-lactide each carry different market values based on their chemical structure and production demands.
Each isomer serves a different job. L-lactide fits medical and pharmaceutical applications where optical purity matters most. D-lactide covers niche markets with specific performance needs.
DL-lactide gives you a cost-effective option for industrial polymers and general-purpose polylactide production. Meso-lactide, when suppliers stock it, sits in its own pricing tier based on availability and demand.
Grade and Intended Application
Industrial-grade lactide is generally purchased for chemical synthesis, PLA Polylactic Acid production, process development, and biodegradable plastics. The purchasing focus is usually repeatable composition, workable packaging, and cost at the required order volume.
Medical-material projects often need tighter controls for identity, impurities, residuals, traceability, and change management. The FDA recognizes ASTM F2579-24 for amorphous poly(lactide) and poly(lactide-co-glycolide) resins intended for surgical implants, which shows why a raw-material purchase for a device program requires more than a generic grade label.
Purity and Product Specifications
High purity is not one measurement. A useful lactide specification can include chemical purity, optical purity, water content, free acid, residual solvents, color, melting range, and particle or package requirements.
For sensitive polymerization work, moisture and acidity deserve special attention. Low free acid, and humidity control are central to achieving reproducible high-molecular-weight polymers.
You should ask the supplier to state the analytical method and acceptance limit for each critical attribute. A quoted purity percentage without a method, a moisture limit, or a current certificate of analysis leaves too much room for mismatch.
Order Quantity
Small quantities carry high handling, packaging, inventory, and quality-control costs per gram. That is why a 25 g catalog pack can cost far more per kilogram than a 250 g pack, even before a supplier offers pilot or commercial pricing.
You can match the request to your real stage of work. Samples suit screening, kilogram quantities support process development, and scheduled multi-kilogram supply can support validation or regular manufacturing.
Testing and Documentation
Extra testing and documentation can add cost, but they often reduce the cost of a failed batch. A meaningful certificate of analysis should identify the material, batch number, release date, test methods, acceptance limits, and numerical results where applicable.
FDA good manufacturing practice guidance states that authentic certificates of analysis should be available for each batch on request and that distributors should maintain traceability records. For regulated work, request these items before approving the quote, not after shipment.
Standard Versus Customized Lactide
Standard lactide is usually the lower-cost option because the supplier can produce, test, and package it against an established specification. It is a practical choice when the default grade meets your polymerization target.
Customized material can require tighter optical purity, lower moisture, a different package format, added release tests, or reserved production scheduling. Those controls increase production costs and can extend lead time, so reserve customization for requirements that directly affect process performance or compliance.
Packaging and Storage Requirements
Packaging protects the usable value of the monomer. Moisture can hydrolyze lactide into lactic acid, and that degradation can affect storage stability and polymerization results.
Lactide should be handled in an environment free of moisture because moisture produces lactic acid. If your process has a strict water limit, request sealed moisture-barrier packaging and define whether you need desiccant, nitrogen protection, or a documented moisture test at release.
Smaller repacked lots can cost more because they add labor, packaging materials, labeling, and potential release testing.
Industrial-Grade vs Medical-Grade Lactide Cost
Industrial and medical-material lactide can look similar on a purchase order, but the supporting quality system can be very different. The correct choice depends on the polymerization process, the final application, and the evidence your organization must retain.
| Consideration | Industrial Grade | Medical-Material Grade |
|---|---|---|
| Primary purchasing goal | Process fit, reliable supply, and commercial economics | Controlled quality attributes and documented traceability |
| Specifications | Standard limits agreed for industrial polymerization | Application-specific limits for identity, impurities, and consistency |
| Testing | Standard batch release testing | Expanded or customer-defined release testing where required |
| Documentation | Commercial documents and standard certificate of analysis | Traceability, quality agreements, change control, and added records |
| Cost driver | Quantity, standard packaging, and availability | Specification limits, documentation, testing, and qualification work |

Laboratory Lactide Prices vs Bulk Lactide Prices
Laboratory lactide prices are higher per kilogram because a small pack concentrates packaging, quality release, inventory, and distribution costs into a limited amount of material. Bulk lactide prices usually improve with volume, but the final result still depends on the specification.
| Purchase Stage | Typical Quantity | Best Use | What to Compare |
|---|---|---|---|
| Laboratory screening | 5 g to 100 g | Initial synthesis and polymerization trials | Isomer, purity, package condition, and certificate of analysis |
| Pilot development | 250 g to multi-kilogram | Process development and repeatability studies | Unit cost, lead time, moisture limit, and batch consistency |
| Commercial supply | Scheduled multi-kilogram or contract volume | Regular manufacturing demand | Annual volume, supply continuity, quality agreement, and landed cost |
The 25 g and 250 g L-lactide catalog examples above show the unit-cost difference in practical terms. Moving from 25 g to 250 g reduced the listed price per kilogram from about $3,720 to $2,228.
Do not assume every larger package produces the same reduction. Higher purity, lower moisture, added documentation, or special packaging can increase the cost even as the order quantity rises.
Can Polylactide Supply Customized Lactide?
Polylactide can review requests for standard and customized lactide types, including L-lactide, D-lactide, and DL-lactide for industrial and medical-material applications. Available options may include sample, pilot, and bulk quantities, custom packaging, and supporting analytical documents.
Customization should begin with a defined performance need. A tighter moisture limit, a higher optical-purity target, a specific package configuration, or expanded batch records can be appropriate if it protects polymerization performance or downstream qualification.
