Send your grade, quantity and destination port — you get a firm offer within one working day.
All grades are suspension-polymerised homopolymer PVC resin, conforming to GB/T 5761-2018, packed in 25 kg PP or kraft bags. The higher the K value, the higher the molecular weight — and the more the grade suits soft, plasticiser-rich products. Low-K grades flow better and go into rigid, transparent work.
The workhorse grade, and the largest volume we move.
Highest molecular weight in our range.
Better flow, higher rigidity in the finished part.
Our lowest K value — best melt flow.
PVC resin is a base material — what it becomes depends on the grade and the formulation. Below are the product families our resin goes into most, with the specific articles inside each. Tell us which one you make and how you process it, and we will confirm the grade before quoting.
Not sure which grade your product needs? Send us the article, your processing method (extrusion, calendering, injection, blow moulding) and your current specification — we will tell you which of the four grades fits, and if none of them does, we will say so.
Suspension process, homopolymer. Specification values below follow GB/T 5761-2018. A batch-specific Certificate of Analysis is issued with every shipment.

Values are typical specification figures, not a guarantee for a specific batch. Please confirm the grade and tolerance you need before ordering — we will send the matching COA.
25 kg PP woven or kraft paper bags with inner liner, 800 kg jumbo bags, or palletised on request. Private-label printing available for volume orders.
FCL and LCL both available; we quote FOB, CFR or CIF to the discharge port you name. Loading arrangements confirmed with you by email.
Commercial invoice, packing list, bill of lading, certificate of origin, and COA. Fumigation, legalisation and third-party inspection arranged when your market requires it.
Standard export packing is a 25 kg bag with an inner liner, suitable for both manual and automated feeding. Larger formats and palletised loads are available when your handling equipment calls for them.
Most suppliers can offer you one plant's output at one plant's price. We hold first-tier agency lines with several producers, which means we can match a grade, a volume and a delivery window to the order actually in front of us — rather than selling you only what we happen to hold.
Agency agreements are signed directly with the producers, so no layer of mark-up sits between the plant and your quotation. We keep adding lines — if your grade is not on the list, ask anyway.
Running another maker's grade code, or you only have the K value? Send it over and we will match it to our SG grades before quoting — so you do not have to guess what will substitute.
Typically 15 to 25 days. If your next production run is time-critical, tell us the rough volume in advance and we will hold allocation with the producer — rather than asking only when you place the order.
Sample orders from a single 25 kg bag, mixed grades in one container, and LCL when a full container is more than your next production run needs.
We export in our own name as the shipper, and handle invoicing, origin certificates and shipping documents in-house — you deal with one counterparty, not a chain of brokers.
English and Hindi-speaking support over WhatsApp, WeChat or email — one person follows your order from enquiry to bill of lading. We work on T/T only: typically 30% down and the balance against a copy of the bill of lading, with the exact split written into the contract. We do not handle L/C.
Buying resin across borders is mostly a question of trust. Below is what we test, what we document, and what is handed over with each shipment. For market-access requirements specific to your country, tell us the destination and the end use and we will confirm item by item — what we can do, and plainly what we cannot.
All grades are produced to GB/T 5761-2018 for suspension polyvinyl chloride resin. Key controlled parameters include K value, viscosity number, volatile content, apparent density, sieve residue, fish eyes, plasticiser absorption, whiteness and residual VCM (≤ 5 ppm).
Third-party inspection — SGS, BV or Intertek — can be arranged at load port at your request and cost. Tell us the inspection scope before production starts.
Sample bags are available for evaluation. Send us the grade, your intended application and your processing method — extrusion, calendering, injection or blow moulding — and we will confirm the grade that fits rather than simply shipping what you asked for. If a different grade would work better for your line, we will say so before you place the order.
For buyers who screen suppliers before issuing a purchase order, our registration details are published below. You are welcome to verify them independently.
Seven steps, and you know what happens at each one before it starts.
Send grade, quantity, packaging and destination port. A specification and your application details help us quote accurately.
Firm offer within one working day — FOB, CFR or CIF, with validity period and payment terms stated.
Sample bag and COA dispatched if you need to test the grade before committing to a volume.
Sales contract or PI signed, T/T deposit received — the price and the shipping window are locked at this point.
Material allocated from the producing plant, third-party inspection arranged if required.
Container stuffed and sealed, with photos of the loaded container sent to you.
Full document set couriered or emailed. We follow the shipment until it clears at your end, and stay reachable after that.
If yours is not here, send it over — you will get a straight answer, including when the answer is no.
One 25 kg bag for a sample. For regular commercial orders we work on a full 20' container basis, and mixed grades in one container are possible. If a full container is more than your next production run needs, ask us for an LCL quotation — we would rather quote small than overstate your order.
SG-5, SG-3, SG-7 and SG-8 are our standard range. Beyond that we can source other suspension grades through the same channel.
As a rule: SG-5 for pipes, profiles and general rigid work; SG-3 for soft products — cable, film, artificial leather — where plasticiser loading is high; SG-7 and SG-8 for rigid sheet, transparent parts and high-flow injection. Tell us your product and process, and we will confirm the grade instead of leaving you to guess.
Both routes reach the same GB/T specification and both are available from us.
Carbide-based resin is made from calcium carbide and is normally the more cost-effective option. Ethylene-based resin, produced from ethylene feedstock, typically shows better batch consistency and lower impurity counts, which matters for transparent and electrical-grade applications. If your end product is sensitive to either, say so and we will quote the route that suits it.
T/T only. Typically 30% deposit with the balance against a copy of the bill of lading, with the exact split agreed per order and written into the contract — nothing is left on a verbal understanding. We do not work on L/C or D/P.
Normally 15 to 25 days from receipt of deposit, depending on grade, quantity and the producing plant's current schedule. Peak season, holiday periods around Chinese New Year, and sudden export-policy changes on your destination market can extend this. We tell you the realistic window in the quotation rather than the optimistic one.
We export in our own name as the shipper and issue the full document set — invoice, packing list, bill of lading, certificate of origin and COA. Where your market needs additional legalisation, fumigation or a specific FTA origin form, tell us before shipment so it is issued correctly the first time.
We can tell you what documentation we issue and what specification the material meets, and we will flag anything we know affects your market. Import licensing, registration and duties are the buyer's responsibility and are governed by your own customs authority.
Ask us before you commit to a price level or a shipping date. Some markets have price thresholds and registration obligations that change how a shipment must be declared, and it is far cheaper to design the order around them than to fix it afterwards.
A trading company, and we never pretend otherwise. Our value sits on the sourcing side: several first-tier agency lines with producers, plus our own export licence. A plant can only offer you its own price and its own schedule; we can pick the better fit for the order in front of us.
Yes. You can appoint SGS, BV, Intertek or your own representative to inspect at the producing plant before shipment — the report comes to you with the documents, or ahead of them. We also send you photographs of the container being loaded and sealed.
Email or WhatsApp, whichever suits you. Tell us the grade, the quantity and the discharge port, and you will get a firm quotation within one working day — not a price on request.
