About Amazon Chemicals Limited - Industrial Chemicals Supplier in China

China‑based Amazon Chemicals Limited lists nine active products across industrial chemicals, petroleum by‑products, wet wipes, emulsifiers, printing paper and paper chemicals. The catalogue includes a water‑based liquid carbomer (HS 3901.90), three grades of alkyl ketene dimer (AKD) wax, a wet‑strength agent, polydadmac polymer, AKD‑based emulsifiers, a surface sizing agent and paper liquid dyestuffs. Each entry reflects a distinct formulation used in paper processing, cosmetics or other industrial applications. The supplier’s portfolio therefore spans polymer additives, sizing agents and specialty dyes that are common inputs for paper manufacturers and formulation chemists.

Product Range and Specialties of Amazon Chemicals Limited

The liquid carbomer is a polyacrylic acid polymer supplied as a water‑based liquid; typical industrial grades have a viscosity range of 1 000 - 10 000 mPa·s and a purity above 99 %. AKD wax grades 1840, 1865 and 1895 refer to iodine values that influence sizing efficiency, with melting points around 70‑80 °C and typical usage levels of 0.2‑0.5 % on paper pulp. The wet‑strength agent is usually a polyamide‑amine resin applied at 0.5‑2 % to improve tensile strength after wetting. Polydadmac, a cationic polymer, is used as a retention aid with a typical molecular weight of 5‑10 MDa and a charge density of 1.5 meq/g. AKD emulsifiers for internal sizing are formulated with HLB values of 8‑10, allowing stable oil‑in‑water emulsions for paper sizing. Surface sizing agents are supplied as aqueous dispersions containing 30‑40 % solids, and paper liquid dyestuffs are offered with color strength (K/S) values calibrated for standard paper bases.

Trade and Export Information - Amazon Chemicals Limited

China is a leading exporter of paper chemicals and polymer additives, and shipments under HS 3901.90 are routinely cleared for markets in Southeast Asia, Europe and North America. Buyers usually require compliance with REACH registration, ISO 9001 quality management and, where applicable, FSC‑compatible documentation for paper‑related chemicals. Standard export packaging includes 20‑ft or 40‑ft containers with 25‑kg drums or 200‑L IBCs, sealed with tamper‑evident caps. Incoterms such as FOB Shanghai or CIF Los Angeles are common for these bulk chemicals, and customs authorities often request a material safety data sheet (MSDS) and a certificate of analysis for each batch.

Sourcing from Amazon Chemicals Limited - Buyer Guidance

When sourcing from Amazon Chemicals Limited, request a full technical data sheet that lists viscosity, pH, purity, iodine value (for AKD wax) and recommended dosage ranges. Ask for a recent batch certificate of analysis and an REACH‑compliance statement to verify that the product meets EU import requirements. Verify packaging dimensions, confirm the HS code used for customs clearance and negotiate a sample order - typically 500 kg or a 25‑kg drum - to assess performance before committing to full‑container shipments.

What is the HS code for the liquid carbomer offered by Amazon Chemicals Limited?

The liquid carbomer is listed under HS 3901.90, which covers other polymers in primary forms.

Which grades of AKD wax are available and what do the numbers indicate?

Three grades - 1840, 1865 and 1895 - are offered; the numbers correspond to iodine values that affect the sizing power of the wax in paper applications.

What documentation should a buyer request before importing the wet‑strength agent?

Buyers should request a material safety data sheet, a batch certificate of analysis, and a REACH compliance statement to satisfy most European import regulations.

Are samples available for the AKD emulsifier and how are they typically sized?

Samples are usually provided in 1‑L bottles or 25‑kg drums; the supplier can arrange a 1‑L sample for performance testing before a larger order.

What are the typical packaging formats for the paper liquid dyestuffs?

Paper liquid dyestuffs are commonly packed in 200‑L intermediate bulk containers or 25‑kg drums, sealed to prevent moisture ingress during transit.

Which markets commonly import the surface sizing agents listed by this supplier?

The surface sizing agents are frequently shipped to paper mills in Southeast Asia, Western Europe and North America, where they are used for improving surface strength and printability.

What certifications are generally required for paper chemicals exported from China?

Importers normally require REACH registration, ISO 9001 quality management certification and, for environmentally sensitive buyers, FSC‑compatible or eco‑label documentation.

What is the typical lead time for a full container order of AKD wax from this supplier?

Lead times for a 20‑ft container of AKD wax are generally 30‑45 days from order confirmation, subject to production scheduling and shipping arrangements.
