Frequently Asked Questions
Common questions about our products and services
What is Jinsu's business scope?
Jinsu is an industry & trade integrated plastic raw material enterprise specializing in ABS, PA6, PA66, PC, transparent PP, FR-PP and custom modified plastic pellets. Our products are exported to over 20 countries worldwide.
Do you provide free samples?
Free samples are 5–10 kg for evaluation; the customer pays shipping. Confirm the selected grade, color, availability and delivery destination with us before arranging the trial.
What is the minimum order quantity (MOQ)?
Free samples: 5–10 kg. Trial orders: minimum 25 kg. Regular production: minimum 1,000 kg. The customer pays shipping costs.
Can you do custom formulations based on samples?
Absolutely. We have professional compounding lines and a lab, and can develop custom formulations and color matching based on your performance and color requirements — including reinforcement, flame retardancy, and more.
What is your lead time?
Stock products: 1-3 working days. Custom compounds: typically 7-15 working days depending on formulation and quantity. Bulk orders — we'll work out a production schedule with you.
What trade terms do you support?
We support FOB, CIF, EXW, and other trade terms. We partner with multiple international logistics companies and can arrange sea, air, and rail freight.
How do you ensure quality?
We are ISO 9001:2015 certified. Every batch comes with a COA (Certificate of Analysis). Third-party testing reports are available upon request.
What payment methods do you accept?
We accept T/T (wire transfer), L/C (letter of credit), Western Union, and other methods. New customers typically use 30% deposit + 70% before shipment.
What information helps you recommend a modified resin grade?
Describe the part, molding process and service environment. Include operating temperature, moisture or chemical exposure, load, impact and dimensional requirements. State the preferred resin, glass-fiber content, flame rating and test thickness, color and appearance target. If available, share the current grade and TDS, the problem you want to solve, trial quantity and delivery destination. This makes the recommendation and quotation specific to your project.
How should I compare two technical datasheets?
Compare the exact grades under matching test methods and conditions. Check units, specimen thickness, dry or conditioned state, and the direction of testing for reinforced materials. Separate typical datasheet values from agreed delivery specifications. A flame-test result at one thickness does not confirm performance at another thickness, and a TDS is not a certification document. Ask for clarification where the test basis differs before ranking the materials.
How do I validate a replacement material before ordering?
Use the comparison to select candidates, then request the current grade-specific TDS and processing guidance. Plan a mold trial and define acceptance criteria before the test. Record drying, melt and mold settings, part dimensions, appearance and the performance checks required by your application. Approve the material only after reviewing the relevant results. Confirm grade, color, quantity, packaging and trade terms in the quotation before a production order.
