The stakes are high. Lead times are long. Small mistakes become expensive. This guide gives practical steps, formulas, and <a href=\"https:\/\/sourcingall.com\/es\/case-studies\/\">examples<\/a>. Read it, apply it, and sleep better at night.<\/p>\n<h2>Start with the basics: lead time and demand<\/h2>\n<p>Two numbers drive reorder points: how fast you sell, and how long it takes to receive stock. For China supply chains that often means long and variable lead times. Break lead time into parts:<\/p>\n<ul>\n<li>Production time (factory). Example: 20\u201330 days.<\/li>\n<li>Packing and inspection. Example: 3\u20137 days.<\/li>\n<li>Inland transport to port. Example: 1\u20135 days.<\/li>\n<li>Sea freight. Example: 25\u201340 days (depends on route and port).<\/li>\n<li>Customs clearance and delivery to your warehouse. Example: 3\u201310 days.<\/li>\n<\/ul>\n<p>Total lead time = sum of all parts. Always use conservative estimates. Add buffer days for Chinese New Year, port congestion, and slow customs.<\/p>\n<h2>Key formulas<\/h2>\n<p>Keep formulas simple and repeatable.<\/p>\n<h3>Reorder point (ROP)<\/h3>\n<p>ROP = Average demand during lead time + Safety stock<\/p>\n<h3>Safety stock (simple method)<\/h3>\n<p>Safety stock = z \u00d7 \u03c3daily \u00d7 sqrt(lead time in days)<\/p>\n<p>Where z is the z-score for your desired service level (e.g., 95% \u2192 1.645). \u03c3daily is the standard deviation of daily demand.<\/p>\n<h3>Economic Order Quantity (EOQ)<\/h3>\n<p>EOQ = sqrt(2 \u00d7 D \u00d7 S \/ H)<\/p>\n<ul>\n<li>D = annual demand (units)<\/li>\n<li>S = <a href=\"https:\/\/sourcingall.com\/es\/get-a-quote\/\">costo<\/a> per order (dollars)<\/li>\n<li>H = holding cost per unit per year (dollars)<\/li>\n<\/ul>\n<p>EOQ gives a theoretical optimal order size. In practice, adjust EOQ to meet supplier MOQs and container constraints.<\/p>\n<h2>Worked example: calculate ROP for a single SKU<\/h2>\n<p>Facts:<\/p>\n<ul>\n<li>Average demand = 50 units\/day<\/li>\n<li>\u03c3daily = 10 units\/day<\/li>\n<li>Total lead time = 55 days (25 production + 30 sea)<\/li>\n<li>Service level target = 95% \u2192 z = 1.645<\/li>\n<\/ul>\n<p>Step 1 \u2014 demand during lead time: 50 \u00d7 55 = 2,750 units.<\/p>\n<p>Step 2 \u2014 safety stock: 1.645 \u00d7 10 \u00d7 sqrt(55) \u2248 1.645 \u00d7 10 \u00d7 7.42 \u2248 122 units.<\/p>\n<p>ROP = 2,750 + 122 = 2,872 units.<\/p>\n<p>Interpretation: place a new order when on-hand inventory drops to ~2,872 units. That keeps you at ~95% service level given the assumptions.<\/p>\n<h2>Practical tips for China-specific risks<\/h2>\n<ul>\n<li>Plan for holidays. Chinese New Year can add 30\u201345 days to lead time if you miss the factory <a href=\"https:\/\/sourcingall.com\/es\/contact-us\/\">cronograma<\/a>.<\/li>\n<li>Account for port variability. Add 5\u201310 buffer days for busy seasons.<\/li>\n<li>Factor MOQ and container fill. If EOQ says 4,500 units but MOQ is 10,000, plan for larger orders or split SKUs to fill a container.<\/li>\n<li>Use pre-shipment inspection. Catch defects before they ship. It\u2019s cheaper than returns.<\/li>\n<li>Negotiate lead-time penalties or partial shipments. Ask for staggered deliveries for large orders.<\/li>\n<li>Consider air freight for critical SKUs. Costly, but fast when you are out-of-stock.<\/li>\n<\/ul>\n<h2>Segment SKUs by demand and risk<\/h2>\n<p>Not all products deserve the same safety stock. Use ABC segmentation.<\/p>\n<ul>\n<li>A items: high value\/high turnover. Target service level 98\u201399% (z \u2248 2.05\u20132.33).<\/li>\n<li>B items: moderate turnover. Target service level 95% (z \u2248 1.645).<\/li>\n<li>C items: slow movers. Lower service level 90% or use periodic review to avoid excess stock.<\/li>\n<\/ul>\n<p>Allocate cash and warehouse space to A items first. For C items, consider just-in-time buys or drop shipping if possible.<\/p>\n<h2>When to override formulas<\/h2>\n<p>Formulas assume stable data. China supply chains are not always stable. Override models when:<\/p>\n<ul>\n<li>Supplier <a href=\"https:\/\/sourcingall.com\/es\/how-we-work\/\">reliability<\/a> drops. Add a fixed buffer of days or units.<\/li>\n<li>You are approaching Chinese New Year. Move orders earlier by at least one production cycle.<\/li>\n<li>Air freight is needed for critical recovery. Shift safety stock rules temporarily.<\/li>\n<li>Container capacity causes you to order more than model suggests. Update forecasts and cash plans.<\/li>\n<\/ul>\n<h2>How often to review<\/h2>\n<ul>\n<li>Weekly for A items. Watch sales and suppliers closely.<\/li>\n<li>Monthly for B items. Recalculate if demand patterns change.<\/li>\n<li>Quarterly for C items. Clear out slow stock and reassess.<\/li>\n<\/ul>\n<h2>Use data and automation<\/h2>\n<p>Manual spreadsheets work for a while. For growth, use an inventory system that:<\/p>\n<ul>\n<li>Tracks supplier lead times and changes.<\/li>\n<li>Calculates ROP and EOQ automatically.<\/li>\n<li>Integrates sales forecast and safety stock rules by SKU.<\/li>\n<\/ul>\n<p>Automation reduces errors. It frees your <a href=\"https:\/\/sourcingall.com\/es\/about-us\/\">equipo<\/a> to handle negotiations and <a href=\"https:\/\/sourcingall.com\/es\/services\/\">calidad<\/a> issues. Think of it as giving your inventory a competent assistant who does math without coffee breaks.<\/p>\n<h2>Final checklist before you place an order<\/h2>\n<ul>\n<li>Confirm supplier lead time and capacity.<\/li>\n<li>Check container and MOQ constraints.<\/li>\n<li>Run the ROP and safety stock calculations.<\/li>\n<li>Factor in holiday and port buffers.<\/li>\n<li>Decide shipping mode (sea vs air) for urgency and cost.<\/li>\n<li>Schedule pre-shipment inspection if quality risk exists.<\/li>\n<\/ul>\n<p>Inventory planning for China requires more buffer and more planning than domestic <a href=\"https:\/\/sourcingall.com\/es\/\">abastecimiento<\/a>. Use clear numbers. Build in common-sense buffers. And have a plan for the big holiday windows.<\/p>\n<p>If you need help building reorder point templates, running EOQ <a href=\"https:\/\/sourcingall.com\/es\/articles\/\">an\u00e1lisis<\/a>, or sourcing reliable factories, Supplier Ally can help.
