Send a request

Tell us the material and the specification

Grade or assay, quantity, packing and the destination port get the quotation right in one round.

Tell us what you need to buy

Send the product name or CAS number, the grade or assay, the quantity, the packing you prefer and the destination port. With those five details we can quote accurately the first time instead of asking you to repeat yourself.

Product and CAS number — for example citric acid monohydrate, CAS 5949-29-1
Grade, assay or purity — food grade, industrial grade, technical grade
Quantity and pack size — sample bag, 25 kg bag, fibre drum, 1000 kg IBC
Destination port and Incoterm — FOB, CIF or another arrangement
Documents your plant requires — TDS, batch COA, SDS, GHS-compliant labelling

Samples and quotations

Samples can be arranged before a bulk order so your laboratory can release the grade first. Quotations are prepared per specification and per quantity, so a figure applies to the configuration quoted and not to the product family as a whole.

Languages

Enquiries are handled in English, Chinese, Russian, Spanish and German. Technical questions are passed to the person who knows that product rather than answered from a script.

Technical data, the batch certificate of analysis and safety data are prepared with the goods for your destination.

We supply a broad portfolio of industrial and food-grade chemical raw materials, including organic acids such as citric acid (monohydrate and anhydrous), surfactants such as LABSA 96%, water treatment chemicals such as polyaluminium chloride (PAC) and cationic polyacrylamide (CPAM), inorganic salts such as zinc sulfate, preservatives such as ethylparaben, plus fluorescent brighteners, molecular sieves and specialty intermediates. Every grade is supported by a technical data sheet and a batch-specific certificate of analysis.

Yes. We provide OEM and ODM services: private-label bag and drum printing, custom pack sizes from 1 kg sample bags up to 1000 kg IBC containers, neutral or buyer-branded packaging, and multilingual labels and documents. We can also blend, mill or repack to your specification, and match the CAS number, purity and particle size required by your process.

MOQ depends on the product. Most commodity grades start at 1 metric ton (25 kg bags or 200 kg drums); specialty and fine chemicals can start from 1 kg or a 25 kg drum for trial orders. Mixed-product container orders are welcome. We can combine several grades to fill a 20ft or 40ft FCL, or ship LCL if you prefer a smaller first order.

Yes. Free samples of standard grades (typically 500 g to 1 kg) are available; you only cover the courier freight, which is refundable against your first bulk order. Samples are dispatched within 3-5 working days together with the COA. Custom-synthesised or specially packed samples take about 7-15 days.
