Grade specifications, equivalencies, HS codes, duty rates, certifications, pricing benchmarks. Ask about any product in the database — get the technical data that takes your team hours to assemble.
“Chinese alternative to LG Chem ME9180 for blown film?”
“What’s the HS code for PP copolymer, density 0.905, into Vietnam?”
“Compare T30S Maoming vs. T30S Zhongke — what’s different?”
Verified Responses
Document verification against published specs and regulatory rules. Forward a CoA — we check every property against the TDS. Forward a Form E — we verify the HS code, FOB value, origin criterion. Landed cost builds with freight, duty, and compliance for your route.
“Can you verify this CoA? MFI says 29 but TDS shows 22–28.”
“Check this Form E before I submit to customs.”
“What’s my total landed cost for HDPE 5000S, Guangzhou to HCMC, 22 MT?”

One question. One answer.
A distributor in Vietnam asked about HDPE pipe grade alternatives. Three matched grades, current CFR pricing, freight and landed cost, documentation status, and quality notes — returned in one response.
3 candidates identified from Chinese producers — Sinopec HDPE 5000S, PetroChina HDPE 5200B, Zhongjin HDPE HMA025. All meet ASTM D3350 PE3408 requirements for pressure pipe.
CFR Ho Chi Minh City: $1,020–1,065/MT (April 2026). Typical Korean-origin CFR: ~$1,140/MT — a $75–120/MT spread on identical performance specs.
Guangzhou → HCMC: 2–5 days transit, $36/MT freight (20ft FCL). Total landed: $1,056–1,101/MT incl. 0% ACFTA duty + 8% VAT.
Form E (ACFTA origin cert), Certificate of Analysis, TDS, HS code 3901.20. All three grades have full documentation available pre-shipment.
Sinopec 5000S: shipped 4x to Vietnam buyers, consistent batch quality. PetroChina 5200B: no prior Vietnam shipments — recommend 1-container trial. Zhongjin HMA025: competitive pricing but limited track record.
Illustrative example based on typical distributor inquiries. Specific grades, prices, and routes reflect representative market conditions.
Document check: The same buyer forwarded a Form E for review. We flagged: “HS code shows 3901.10 (LDPE) but CoA density of 0.954 classifies as 3901.20 (HDPE). This will be rejected at Vietnam customs. Request correction from CCPIT — takes 2–3 business days. Your vessel loads Thursday.”
Illustrative example based on typical distributor interactions. Specific grades, prices, and routes reflect representative market conditions.
What happens when your best person leaves?
Your senior trader answers questions like that from memory. But that knowledge is locked in their head.
They know which Sinopec grades run cleanest on your customers' lines. Which CCPIT offices process Form E corrections fastest. Every buyer's reorder cycle.
Then they leave. It takes a year to rebuild what they knew.
Some of it is never rebuilt.
Everything your team asks, every document verified, every grade note — it stays. No knowledge walks out the door.

Subscribe — FreeWhat we don't promise
We do three things: match grades, verify documents, and manage execution. Here is what each one cannot guarantee.
We match grades. We don’t guarantee production outcomes.
A spec match is not a production guarantee. Processing behavior, batch consistency, and downstream quality depend on your equipment and conditions. We provide the data. You make the decision.
We verify documents. We don’t eliminate customs risk.
We check for HS code mismatches, Form E errors, and cross-document inconsistencies before shipping. But customs authorities make final decisions, and regulations change without notice.
We tell you when we don’t know.
If we haven’t shipped a grade before, we say so. If a spec match looks marginal, we flag it. If the pricing doesn’t justify the switching cost, we’ll tell you that too.
The gap between a datasheet and a production floor is real. Our job is to close it with better information and the honesty to tell you when we can't.
