Imported PP/PE grade?
Start with the right Chinese match.

We compare your current PP/PE grade, TDS, application and processing route with suitable Chinese candidates before quotation. Producer, supply channel, batch COA and commercial terms are confirmed per grade and order; a grade name or one MFR value alone is not proof of equivalence.

Verify source, channel and batch documents

A grade match is not an unconditional drop-in guarantee; the buyer approves the trial criteria and any production release.

Core capability: imported resin grade migration

A grade match is more than swapping one name for another.

We start with the grade in use, the processing route and the properties that matter. Then we document candidate grades, evidence, differences and open checks. Similar MFR does not automatically mean drop-in equivalence.

01

Start with the current grade and process

Start with the imported reference grade, TDS, end use and process. If key information is missing, we state the assumptions instead of treating unknowns as confirmed.

  • Current grade and producer
  • Application and process
  • Quantity, destination and timing
02

Compare properties that matter for the resin and use

Select comparison points by resin family, process and end use. MFR/MI, density, impact and stiffness are checked where relevant—not treated as a universal checklist.

  • Property-by-property TDS
  • Differences and limitations
  • Open checks clearly marked
03

Verify producer and supply channel

Yuhua Yunchuang is a designated first-tier agent for Guangdong Petrochemical (PetroChina). Appointment scope, producer and supply channel are confirmed grade by grade for each RFQ.

  • Appointment scope by grade
  • Availability and terms in quotation
  • Batch COA confirmed per order
04

Trial first, then decide whether to scale

The comparison separates verified data, typical values and open questions. The buyer evaluates a trial under agreed processing conditions before deciding whether to scale.

  • Trial objectives and acceptance criteria
  • Batch COA and agreed testing
  • Buyer-approved production release

No one-number shortcuts

A similar melt-flow value is not proof of a safe substitute.

We select comparison points by resin family and end use. Beyond MFR/MI, the review may need density, impact, stiffness, additives, processing route and destination requirements. The actual checklist follows the current TDS, buyer specification and intended use.

Core export categories

Start with PP/PE resin; other sourcing requests remain available.

Our primary focus is PP/PE grade matching and export supply. Listed grades describe assessment scope, not live inventory; producer, appointment scope, quantity and timing are confirmed per RFQ.

Supporting capability: export documents

For confirmed orders, align documents and delivery milestones with the destination.

The route for contracts, commercial invoices, origin documents and authorizations varies by document type, destination, Hague Convention applicability and receiving authority. We prepare materials and coordinate the process; we do not replace CCPIT bodies, notaries, foreign affairs authorities, embassies or consulates.

Grade migration workflow

Evidence first. Quote next. Trial before scaling.

  1. 01

    Share the reference grade

    Current grade, TDS, application, processing route, quantity and destination.

  2. 02

    Confirm critical requirements

    Separate must-have limits, target properties and acceptable trade-offs.

  3. 03

    Build a candidate comparison

    List the matching rationale, differences, source and open checks.

  4. 04

    Verify supply and quotation

    Confirm producer, channel, quantity, batch documents and trade terms by grade.

  5. 05

    Run an agreed trial

    The buyer evaluates under the target process and agreed criteria; deviations are documented.

  6. 06

    Scale after buyer approval

    Proceed to a bulk order only after the trial, final specification, batch COA and delivery terms are approved.

Grade migration FAQs

Understand the basis and limits of a grade match.

Does a Chinese grade match guarantee a drop-in replacement?
No. A candidate is assessed against the current TDS, application and processing route. The buyer validates it against agreed trial criteria before production release.
What information is needed for a PP or PE grade review?
Share the current grade and TDS, application, process, critical properties, expected quantity and destination. Missing inputs remain open checks.
Are listed grades always in stock?
No. Listed grades describe the assessment scope, not live inventory. Producer, appointment scope, channel, quantity and timing are confirmed per RFQ.
Can you assess PE resin requirements?
PE inquiries can be assessed by the reference grade, TDS and application; the exact grade, source and terms must be confirmed for the order.

Send a PP/PE grade enquiry

Send the current grade and TDS; start with a fit review.

Include the application, process, critical properties, estimated volume and destination where available. We will state open questions; a formal quotation follows grade-source, availability and order-scope checks.

Start with a grade review. No purchase commitment; the buyer decides on trial and scale-up.
