Where to buy shellac flake in the US: a specifier's guide

Shellac is a small, specialized supply chain. The resin starts as a crust on host trees in India and Thailand, moves through a handful of refiners, and reaches US buyers through a short list of importers and distributors. When a coatings maker, ink formulator, or finishing shop goes looking for flake, the question is rarely whether shellac exists somewhere; it is which supplier will still look good on the third order. Here is what to check.

Where to buy shellac flake in the US

P.A.T. Products stocks Lemon #1 flake shellac in North America and ships from inventory, with a Certificate of Analysis on every lot. We have supplied shellac for more than 35 years, one of our oldest lines, through direct relationships with established producers in India. High-flow, dewaxed, bleached, and cut grades are available by arrangement. The shellac product page carries the full grade and application detail; what follows is the checklist we would apply to any shellac supplier, ourselves included.

Check 1: stock on this side of the ocean

Shellac imports move by ocean freight from India, and a supplier who orders against your order is adding weeks to every delivery. US inventory means a formulation trial, a production run brought forward, or a spot outage gets material in days. It also means someone has already taken the import risk, cleared customs, and accepted the lot before you see it.

Check 2: a COA on every lot, with the numbers that matter

Shellac is a natural product, and lots differ. A serious supplier issues a Certificate of Analysis per lot and is comfortable being asked about the three working numbers: flow, polymerization time (life), and hot alcohol insolubles. Flow tells you how the resin melts and levels, life tells you how much usable shelf time remains, insolubles tell you how clean the refining was. What each number measures, and what good looks like, is covered in reading a shellac COA. A supplier who cannot produce these numbers is asking you to run their QC for them.

Check 3: freshness, stated rather than implied

Shellac polymerizes slowly from the day it is refined. As a lot ages, flow drops, dissolving slows, and dry times stretch. The failure is gradual and then sudden: a cut that took hours starts taking days, a bond or film stays soft. Ask when the lot was produced, and prefer a supplier whose inventory turns. Per-lot life values on the COA are the honest version of a freshness claim.

Check 4: the grade range behind the flake

Most industrial buying is waxy flake, and Lemon #1 is the standard grade. But program needs move: a finishing customer wants dewaxed for topcoat compatibility, a food or pharma application needs the dewaxed feedstock and its documentation, an abrasives buyer needs high-flow. A supplier who can source across the refining routes, flake, dewaxed, bleached, and cut solutions, saves you a second qualification when the second need appears. The routes and what separates them are covered in shellac grades and forms.

Check 5: documentation matched to the application

Shellac's regulatory footing is strong: CAS 9000-59-3, FDA GRAS under 21 CFR 172.800, glazing agent E904 in the EU. What a buyer needs is the paperwork matched to the use: food-contact documentation for glaze and tablet work, SDS and technical data for industrial coatings and inks, and per-lot analysis wherever a spec is on file. State the application when you order; the right documentation should follow without a chase.

Frequently asked

Who supplies shellac flake from US stock?

P.A.T. Products stocks Lemon #1 flake shellac in North America and ships from inventory, with a Certificate of Analysis on every lot. We have supplied shellac for more than 35 years through direct relationships with established producers in India. High-flow, dewaxed, bleached, and cut grades are available by arrangement.

What should a shellac COA include?

The three working numbers are flow, polymerization time, and hot alcohol insolubles, alongside identity and purity items such as wax content, moisture, and color. Flow and life tell you how the resin will process and how much shelf life remains; insolubles tell you how clean the refining was.

Why does shellac freshness matter?

Shellac slowly polymerizes from the day it is made. As it ages, flow drops, dissolving slows, and dry times stretch until an old lot no longer performs. A supplier turning inventory and reporting life per lot is how a buyer avoids inheriting stale stock.

Is flake shellac food grade?

Shellac is listed GRAS by the FDA under 21 CFR 172.800 and carried as E904 in the EU. Confectionery glaze and pharmaceutical coating normally run on a dewaxed grade rather than waxy flake, so state the application and match the documentation to it.
