We understand your pursuit of efficiency. Instead of stocking up and tying up capital, focus on two golden combinations: general-purpose engineering plastics (such as nylon and POM) to meet the essential needs of industrial equipment upgrades, and general-purpose materials (PP and PE) to cover daily processing needs. These products inherently possess high-volume characteristics—customers purchase frequently and have short decision-making chains, allowing your inventory to circulate quickly and leveraging 30% of your capital to generate 80% of orders. We have compiled a list of best-selling models and tiered inventory management strategies to help you start with a lighter load and seize market opportunities.
Ⅰ. Top High-Turnover Core Products
1. POM (Polyoxymethylene) Sheets/Rods – The "Universal Material" for Mechanical Structural Components, the King of Turnover
Reasons for Hot Sales
Comprehensive Performance: High rigidity, high hardness, self-lubricating, wear-resistant, fatigue-resistant, dimensionally stable, oil/solvent resistant, and mechanical properties close to metals.

Specialty Supplement (20% Inventory): PMMA, PTFE (Teflon), PEI, PEEK (Small Batch, Targeting High-End Customers).
2. Specification Stocking Principles (Fewer Specifications, More Thickness/Diameter)
Sheets: Primarily 5/10/15/20/30mm thick, 1000/1220/1500mm wide, 2000mm long (standard sheets).
Rods: Primarily 10/15/20/25/30/40/50mm diameter, 1000mm long (standard rods).
Color: Prioritize white/black/natural/dark gray, covering 80% of demand; small-batch customization of colored products is also available.
3. Inventory Turnover Optimization
Initial Order Strategy: Prepare 1-2 tons of standard specifications for each core product, keeping total inventory at 5-8 tons to reduce financial pressure.
Dynamic Replenishment: Replenish based on monthly sales × 1.2; maintain a safety stock of ≥ 2 weeks' sales for best-selling specifications.
Shortcut Service: Offer custom cutting to customer dimensions to improve turnover and reduce stockpiling of whole sheets and bars.
Supplier Selection: Find source factories/first-tier agents to ensure low prices, fast delivery, and stable quality, supporting small-batch replenishment.
Ⅳ. Pitfalls to Avoid (Common Mistakes for Beginners)
Don't stock up on specialty plastics (PEEK/PI/PEI) from the start: High unit price, small usage volume, slow turnover, easily tying up capital.
Don't stock too many non-standard specifications/colors: Low demand, difficult to sell, increasing inventory risk, unless sales are already stable and you want to use new categories to boost sales.
Prioritize general-purpose engineering plastics + cost-effective general-purpose plastics, first establish a stable turnover and accumulate customers, then gradually expand the product line.
