About Fenchem Biotek Ltd. - Industrial Chemicals Supplier in China

Fenchem Biotek Ltd. is based in China and lists 16 active products across industrial chemicals, plastic raw materials and construction chemicals. The catalogue includes hydroxypropyl methylcellulose (HPMC), redispersible polymer powder, diacetone acrylamide (HS 2924.19, 99 % minimum purity), DMP‑30 (HS 2933.59, a tertiary amine), trimethylolpropane (TMP), polyisocyanate L‑75 (HS 2929.10, aromatic TDI‑based), superplasticizer for concrete and mortar (HS 3824.40, melamine sulfonate and polycarboxylate ether), calcium formate, phenolic antioxidant, Fischer‑Tropsch wax, C5‑C9 aliphatic/aromatic hydrocarbon resin, DCPD C9 resin, anhydrous citric acid, N‑butyl stearate and multifunctional additive AMP95. The product list also contains a generic entry titled “Industrial Chemicals”.

The listed items span HS‑code families 2924, 2933, 2929 and 3824, covering monomers, amine catalysts, polyisocyanates and concrete admixtures. Several entries lack explicit HS codes, which is common for bulk chemicals where the tariff classification depends on final formulation. The supplier’s portfolio reflects typical Chinese exporters of specialty chemicals used in polymer synthesis, coatings, and cement additives.

Product Range and Specialties of Fenchem Biotek Ltd.

Fenchem’s catalogue focuses on specialty intermediates for polymers and construction applications. Diacetone acrylamide is supplied at a minimum purity of 99 %, a grade commonly required for UV‑curable resins and acrylic copolymers. DMP‑30 functions as a tertiary amine accelerator in epoxy and polyurethane systems, and is usually shipped in 25 kg drums meeting ISO 9001 quality‑management standards (though the supplier’s own certifications are not listed). Polyisocyanate L‑75, based on toluene diisocyanate, is a standard component for flexible foam formulations and typically adheres to the ISO 21493 “Polyurethane - Polyisocyanates” specification. Superplasticizer concrete and mortar blends combine melamine sulfonate with polycarboxylate ether (PCE) at dosage levels of 0.1 - 0.5 % by cement weight, a specification widely referenced in EN 197‑1 for cement admixtures.

Other chemicals such as calcium formate, phenolic antioxidant, Fischer‑Tropsch wax and hydrocarbon resins are standard raw materials for construction chemicals, lubricants and adhesives. Typical grades include calcium formate ≥ 99 % purity, phenolic antioxidant with a phenol content of 85 % and wax melting points between 80‑100 °C. The hydrocarbon resin range (C5‑C9) is often supplied with a softening point of 70‑90 °C and a resin acid number below 30 mg KOH/g, matching the requirements for tire tread compounds and printing inks.

Trade and Export Information - Fenchem Biotek Ltd.

China is a global exporter of specialty chemicals, and shipments of the HS‑code groups present in Fenchem’s list (2924‑2929, 3824) are routinely dispatched to Southeast Asia, the Middle East, Europe and North America. Buyers of diacetone acrylamide, DMP‑30 and polyisocyanates often require compliance with REACH registration for the EU, TSCA for the United States, and local safety data sheet (SDS) standards. Common certifications requested include ISO 9001 for quality management and ISO 14001 for environmental compliance, although Fenchem does not disclose holding these certificates in the provided data.

Typical export packaging for bulk chemicals from China includes 25 kg or 50 kg IBCs, 20 ft and 40 ft containers, and bulk tankers for liquid waxes. Freight terms such as CIF or FOB are standard, with customs clearance requiring the HS code, material safety data sheet and, where applicable, a certificate of analysis (CoA). Chinese customs may also request a declaration of the intended end‑use to verify compliance with dual‑use export controls for certain polyisocyanates.

Sourcing from Fenchem Biotek Ltd. - Buyer Guidance

When sourcing from Fenchem, buyers should request a current certificate of analysis for each chemical, confirming purity (e.g., 99 % for diacetone acrylamide) and any specified impurity limits. For polymer additives such as the superplasticizer, the SDS should list the exact melamine sulfonate and PCE concentrations, as well as the recommended dosage range. Verification of REACH registration or equivalent regional compliance is advisable before loading the cargo.

Sample quantities are typically 1 kg for powders and 0.5 L for liquids, shipped under DAP terms. Lead times for standard chemicals from Chinese manufacturers range from 15 to 30 days after purchase order confirmation, while custom‑synthesized grades may require 45 days or more. Buyers should also confirm packaging dimensions (e.g., 25 kg drums fit six per 20 ft container) and ensure that the freight forwarder can handle hazardous material classification if required.

What HS codes apply to Fenchem’s listed chemicals?

The catalogue provides HS codes for diacetone acrylamide (2924.19), DMP‑30 (2933.59), polyisocyanate L‑75 (2929.10) and the concrete superplasticizer (3824.40); other items fall under the broader headings 2924 - 2929 for organic intermediates and 3824 for building‑material chemicals.

What purity level does Fenchem offer for diacetone acrylamide?

The product is listed with a minimum purity of 99 %, which aligns with the grade commonly required for acrylic resin manufacturing.

Which documentation should a buyer request before purchasing polyisocyanate L‑75?

Buyers should obtain a current Certificate of Analysis, the Safety Data Sheet, and evidence of any REACH or TSCA registration applicable to aromatic polyisocyanates.

How are Fenchem’s bulk chemicals typically packaged for export?

Industry practice for the listed chemicals is 25 kg or 50 kg IBC drums, stacked six per 20 ft container, or bulk tanker loading for waxes; packaging details should be confirmed in the commercial invoice.

What incoterms are commonly used for shipping Fenchem’s products?

Exporters from China frequently use FOB (Free on Board) or CIF (Cost, Insurance, Freight) to major ports such as Shanghai or Shenzhen, depending on buyer preference.

What minimum order quantity applies to the superplasticizer for concrete and mortar?

The superplasticizer is usually sold in 25 kg drums, with an MOQ of one drum (25 kg) for most international buyers.
