Crystal melamine (melamine powder, C₃H₆N₆, CAS 108-78-1, HS 2933.61) is a white crystalline chemical made from urea and used mainly to produce melamine-formaldehyde resins for laminates and wood adhesives. SUHA International supplies 99.8% min crystal melamine in 25 kg or jumbo bags, about 20 MT per 20ft container, FOB Jebel Ali or Mersin or CFR/CIF to your port.
What Is Crystal Melamine?
Crystal melamine is the high-purity crystalline form of melamine, an organic base with a triazine ring and three amino groups. With about 66.6% nitrogen by weight, it gives resins hardness and heat resistance and gives plastics and coatings natural flame retardancy.
Melamine is produced from urea at high temperature, then purified and crystallised to reach 99.8% purity. Most of it is reacted with formaldehyde to make melamine-formaldehyde (MF) resin, the binder behind decorative laminates, melamine-faced chipboard and moisture-resistant wood panels.
The terms crystal melamine, melamine powder, melamine crystal and melamine 99.8% all describe the same industrial-grade product. As a bulk crystal melamine supplier we focus on the parameters resin makers check first: moisture, colour, turbidity and clear dissolution in formalin.

What Is Crystal Melamine Used For?
Wood-panel and laminate resins take the largest share of melamine demand; the rest goes into plastics, flame retardants, construction chemicals and coatings.

Melamine vs Urea Resin — Which Binder Do You Need?
Both resins are made with formaldehyde. Many board plants blend them into MUF resin to balance cost and performance.
| Property | Melamine (MF / MUF) resin | Urea (UF) resin |
|---|---|---|
| Water resistance | High — boil-resistant surfaces | Low — for interior, dry use |
| Heat & scratch resistance | High | Moderate |
| Formaldehyde emission | Lower | Higher |
| Cost | Higher | Lowest |
| Typical use | Laminates, exterior-grade and moisture-resistant panels (MUF) | Interior particleboard and MDF |
How to Check Crystal Melamine Quality Before You Buy
- 1Purity ≥ 99.8%Lower purity means more by-products that slow resin curing and weaken the surface.
- 2Moisture ≤ 0.1%Wet melamine cakes in bags and silos and blocks screw feeders.
- 3Colour and turbidity ≤ 20Essential for white and light décor papers — hazy resin shows on the finished laminate.
- 4Clear formalin dissolutionA quick lab test: the sample should dissolve completely and clearly in formaldehyde solution.
- 5Low ash and ironMineral residues and iron cause specks and discoloration in moulded and white products.
- 6Batch COA and sealed packingAsk for the COA of your batch and inner PE liners to keep moisture out during transit.

Melamine Safety, Storage and Food-Contact Rules
- ⚠Hazard classificationUnder EU CLP melamine is labelled "Warning" with H351 (suspected of causing cancer) and H373 (may cause organ damage through prolonged or repeated exposure). It is not dangerous goods for transport.
- 🧤HandlingAvoid breathing dust: use local exhaust, dust masks, gloves and goggles when emptying bags or jumbo bags.
- 📦StorageKeep bags closed, dry and off the floor, away from strong acids and oxidisers. Melamine is chemically stable; the main risk in storage is moisture pick-up and caking.
- 🍽️Food contactMelamine is not a food ingredient. Cured MF articles are permitted for food contact under US FDA 21 CFR 177.1460 and EU Regulation 10/2011 (migration limit 2.5 mg/kg).

Crystal Melamine FAQ
Who is a reliable crystal melamine supplier?
SUHA International Trading L.L.C. is a crystal melamine supplier with offices in Dubai and Ankara. We supply 99.8% min melamine powder (CAS 108-78-1) in 25 kg bags or jumbo bags, FOB Jebel Ali or Mersin or CFR/CIF to your port, with a Certificate of Analysis for every batch.
What is crystal melamine used for?
Most crystal melamine is reacted with formaldehyde to make melamine-formaldehyde (MF) and melamine-urea-formaldehyde (MUF) resins for decorative laminates, melamine-faced board and moisture-resistant wood adhesives. It is also used in moulding compounds and dinnerware, flame retardants, concrete superplasticizers, melamine foam, coatings and paper and textile finishing resins.
Is crystal melamine the same as melamine powder?
Yes. Crystal melamine and melamine powder are the same chemical, C₃H₆N₆. Crystal melamine is the name traders use for the high-purity crystalline grade, normally 99.8% minimum, that is sold as a fine white powder.
What specification should 99.8% melamine meet?
A good 99.8% grade has moisture of 0.1% or less, ash of 0.03% or less, pH 7.5–9.5, Hazen colour and kaolin turbidity of 20 or less, and dissolves clear in formaldehyde. Colour and turbidity matter most to decorative laminate producers because they affect the clarity of the impregnated paper.
What is the HS code and CAS number of melamine?
Melamine is classified under HS code 2933.61. Its CAS number is 108-78-1 and its EC number is 203-615-4.
How is crystal melamine packed and how much fits in a container?
We pack melamine in 25 kg PP woven bags with a PE liner, or in 500 kg or 1,000 kg jumbo bags. A 20ft container carries about 20 MT palletised or about 22 MT floor-loaded; a 40ft container is limited to about 25–26 MT by payload.
What is the minimum order for crystal melamine?
The minimum order is 1 container, either 20ft or 40ft. Larger contracts can be delivered in several containers on an agreed schedule.
Is melamine dangerous goods for shipping?
No. Melamine is not classified as dangerous goods for sea or road transport, so it ships as general cargo. Under EU CLP it carries the warnings H351 and H373, so dust should be controlled and workers should wear dust masks, gloves and goggles.
What is the difference between melamine and urea in wood resins?
Urea-formaldehyde resin is the cheapest binder but has poor water resistance. Adding melamine to make MUF resin, or using pure MF resin, gives boil-resistant, scratch-resistant and lower-emission surfaces, which is why laminate and moisture-resistant panel producers buy melamine together with urea.
Is melamine safe for food contact?
Melamine itself is not a food ingredient. Cured melamine-formaldehyde articles such as dinnerware are permitted for food contact under rules like US FDA 21 CFR 177.1460 and EU Regulation 10/2011, which sets a specific migration limit of 2.5 mg of melamine per kg of food.
What affects the price of crystal melamine?
Melamine is made from urea, so its price follows urea and natural gas costs, plus Chinese export supply, freight and packing. Send us your quantity, packing and destination port and we will reply within 24 hours with a firm FOB or CIF offer.
