Q1: Does your quotation include the highest-quality rubber material? What is the rubber-to-calcium-powder ratio? Do you offer a higher-grade material with greater rubber content, improved flexibility, or better durability? A: Yes, our standard quotation includes our premium rubber formula tailored for high-end mahjong table mat. The rubber-to-calcium-powder ratio is well calibrated to balance flexibility, durability and stable playing performance. We have an upgraded option with higher rubber content, softer touch and longer service life.

Q2: What type of fabric is used for the sublimation printed surface? Is it a smooth polyester fabric or microfiber? Is this the surface you recommend for American mahjong tiles to slide smoothly without excessive slipping? A: The printed playing surface is smooth polyester fabric. This is our recommended surface for American mahjong games. It delivers ideal sliding resistance: mahjong tiles move smoothly, not too slippery nor sticky, matching the playing habits of US mahjong players.

Q3: Can the finished mats be machine washed? Are they suitable for tumble drying, or should they be air dried? Have you performed testing for colorfastness, washing durability, and resistance to fading? Do the mats contain natural latex? A: Hand wash and air dry are recommended. Machine washing and tumble drying are not advised to protect the sublimation print and neoprene base. We have completed colorfastness, wash durability and anti-fading tests. Our neoprene mahjong table mat contains NO natural latex, friendly for latex-sensitive users.

Q4: Do your materials comply with US market chemical regulations? A: Yes. We have the latest California Proposition 65 test report for our mat materials, tested following the 3-in-1 mixing test standard. Our products meet the chemical safety requirements for sales in the US market.

Note: The below parameters take 33" (finished‑size 840 × 840 mm) mahjong mat as an example. Apply the same logic to other regular sizes.

1. Finished product size: 840 × 840 mm. Full artwork dimension with bleed: 853 × 853 mm.
2. Bleed: 6.5 mm bleed on all four sides.
3. Safe zone: Keep all critical graphics, texts, logos and borders 10 mm inside the finished 840×840 mm cut‑line, to prevent content being trimmed off during trimming and overlock‑stitching.
4. Print & cut alignment tolerance: Material shrinkage & tolerance ranges from 5‑10 mm. We will try our best to keep tolerance around 5 mm.
5. Resolution: Minimum 300 DPI at full 1:1 actual size.
6. Preferred file format: AI / High‑resolution PDF / EPS. Please also supply a JPG version for visual cross‑check to avoid mistakes.
7. Color mode: CMYK.
8. Artwork scale: Submit files at full 1:1 real‑world size.
9. Design with borders or centered elements: Place border elements inside safe zone to avoid visual offset caused by stitching tolerance.

Please contact us for the official standard die‑cut‑line template after your final mat size is confirmed.

Q1: Are your neoprene mahjong mats compliant with California Prop 65 for US sales? A: Yes. Our neoprene mahjong mats have passed official third-party California Prop 65 lab testing, fully compliant for wholesale, Amazon, and US local mahjong store sales. All tested hazardous substance items meet US safety standards.

Q2: What testing standard do you follow for Prop 65 certification? A: We follow the US official 3-in-1 mixed homogenized sampling standard for finished consumer goods. Multiple representative areas of the finished mat (surface fabric, rubber bottom, edge material) are sampled and mixed for unified testing. This is the standard method recognized by CPSC and California Prop 65 for finished neoprene mats.

Q3: Why do you use mixed sampling instead of separate layer testing? A: Layer-by-layer testing is only applied to raw material inspection. For finished neoprene mahjong mats sold in the US market, industry regulations require mixed sampling testing to reflect the overall safety of the final product. This is the universally accepted US industry standard.

Q4: What substances are tested in your Prop 65 report? A: The test covers four core restricted substances required for US consumer goods: Lead (Pb), Cadmium (Cd), Phthalates, and BPA. All results are non-detected or fully within safe limits.

Q5: Is your Prop 65 report accepted by Amazon and US local mahjong stores? A: Yes. Our mixed-sampling Prop 65 test is the official standard for finished mats. It is widely accepted for Amazon listing compliance, US customs clearance, wholesale distribution, and physical mahjong store retail sales.

Q6: Does a Prop 65 passing result mean no warning label is required? A: Not exactly. Prop 65 labeling rules vary by sales state, sales channel, and consumer exposure scenarios. Final label requirements should be confirmed by your local sales or compliance team.

Q7: Is the Prop 65 report still valid for custom printed mahjong mats? A: Yes. If only artwork, patterns, or logos are customized without changing raw material composition, the Prop 65 test report remains valid.

Q8: Can you provide the official Prop 65 test report file? A: Yes. We provide complete official PDF lab reports for customer compliance filing, Amazon verification, wholesale cooperation, and import documentation.
