PVC Resin (Suspension Grade)

Suspension PVC by K-value for pipe, profile, cable and film

Suspension PVC (S-PVC, HS 3904.10) is a fine white powder, not a pellet, and it is graded on K-value, the viscosity number that stands in for molecular weight. K57–58 is the injection-moulding and rigid-bottle resin; K65–67 is the rigid extrusion workhorse for pressure pipe, drainage pipe, fittings and window profile, and is the grade most buyers in our markets mean when they say PVC; K70–71 is the flexible resin for cable insulation and sheathing, hose, footwear and calendered soft film, where it takes 30–60 phr of plasticiser. A datasheet then carries bulk density (0.45–0.60 g/cm³, which sets extruder output), particle size (typically 98% or more through 250 µm and no more than a few percent retained on 63 µm), volatiles (≤ 0.3%), residual vinyl chloride monomer (≤ 1 ppm, and ≤ 5 ppm for non-food grades), plasticiser absorption (for flexible grades) and fish-eyes. Ethylene-based and carbide-based (acetylene) PVC are chemically the same polymer, but carbide resin from coal-based producers tends to run higher in fish-eyes and residual impurities and is priced below ethylene-based Gulf, US and Southeast Asian resin. UN Comtrade 2025 export declarations under HS 3904 (the whole heading, which also carries compounds and copolymers) put the USA at 3.81 million MT at an average USD 1,028/MT, Thailand at 0.51 million MT at USD 964, Indonesia at 0.46 million MT at USD 665, Egypt at 0.18 million MT at USD 1,052, Saudi Arabia at 0.17 million MT at USD 809 and Canada at 0.17 million MT at USD 1,141. The US 2025 destination list separates resin from compound by price: Viet Nam 0.40 million MT at USD 666/MT, Türkiye 0.39 million MT at USD 683, India 0.11 million MT at USD 900, Egypt 0.06 million MT at USD 680 and Nigeria 0.06 million MT at USD 733 are commodity suspension resin; Canada at USD 1,134 and Mexico at USD 1,563 are compound-heavy cross-border flows.

The buyer is a pipe or profile extruder, a cable compounder, a calendering plant or a distributor, and it buys a delivered container of one K-value against the resin it runs now, because a change of resin means re-tuning the dry-blend formulation of stabiliser, lubricant, filler and impact modifier. PVC moves in 25 kg bags on pallets or 1,000–1,250 kg jumbo bags in 40-ft containers at about 24.75 MT each; the chartering desk is not the point here, and container freight is quoted through forwarders against the destination port. CBIL is a commodity brokerage company and brokers suspension PVC from the offtake traders of US, Gulf, Southeast Asian and Egyptian producers, and from trader parcels of prime and near-prime resin, against the producer's certificate of analysis and SGS or Intertek inspection at stuffing where the buyer wants it. Parcels run from a single 40-ft container to monthly programmes on FOB, CFR and CIF terms into Mersin, Alexandria, Mombasa, Karachi, Chittagong and Haiphong. Send the K-value you run, whether the application is rigid or flexible, the bulk-density band your extruder is tuned to, and the monthly volume, and we will work an origin and a landed number to it.
