Updated weekly. SNNP Verified Compliance Index: Real-time BSCI/Sedex/ISO 9001 audit pass rate across SNNP's vendor network, calculated from third-party audit records. SNNP Smart Routing: AI-driven sourcing workflow that matches buyer requirements to verified suppliers in SNNP's network based on industry category, MOQ tolerance, and certification requirements. HS Code: The Harmonized System (HS) Code is a 6-digit international product classification number maintained by the World Customs Organization and used on all import/export declarations worldwide. Declaring an incorrect HS Code can trigger customs holds, re-inspection fees, or duty reassessment at destination. SNNP verifies HS Code accuracy on all commercial invoices before shipment as part of its customs clearance support. CBM (Cubic Meter): CBM (Cubic Meter) is the standard volume unit used to calculate sea freight charges — calculated as length × width × height in metres. For LCL (Less than Container Load) shipments, ocean freight is priced per CBM; for FCL, the full container rate applies regardless of fill level. Accurately estimating your cargo's total CBM before ordering lets buyers compare LCL vs FCL economics and forecast landed cost. PI (Proforma Invoice): A Proforma Invoice (PI) is a binding pre-shipment document issued by a supplier confirming product specifications, unit price, quantity, payment terms, and delivery conditions before the final purchase order is placed. Buyers require the PI to arrange T/T wire transfer, apply for a Letter of Credit (L/C), or obtain import permits. SNNP reviews PI accuracy — including unit price, HS Code, and payment clause — as a standard step in the order confirmation process. BOM (Bill of Materials): A Bill of Materials (BOM) is a structured inventory of every raw material, sub-component, sub-assembly, and finished part required to manufacture one unit of a product. Providing a complete BOM to your sourcing agent enables accurate multi-supplier quoting and prevents mid-production material substitutions that cause quality deviation. SNNP uses buyer-supplied BOMs during the RFQ phase to cross-check factory quotes and flag hidden cost risks. Incoterms 2020: Incoterms 2020 are 11 standardised International Commercial Terms published by the International Chamber of Commerce that define exactly where delivery obligations, risk transfer, and cost responsibility shift from seller to buyer. The three terms most relevant to China import: FOB (buyer assumes risk once goods are loaded on vessel at origin port), CIF (seller pays freight and insurance to destination port), and DDP (seller delivers cleared and duty-paid to buyer's address). Selecting the wrong Incoterm is one of the most common causes of unexpected landed-cost overruns for first-time China importers. DDU (Delivered Duty Unpaid): DDU (Delivered Duty Unpaid) is a legacy Incoterm — replaced by DAP in Incoterms 2020 — under which the seller delivers goods to the named destination but the buyer remains responsible for import duties, VAT, and customs clearance costs. Buyers who accept DDU terms must budget for in-country customs broker fees and the risk of holds if duties are underpaid. SNNP recommends DDP pricing for first-time importers to eliminate customs uncertainty, and offers DDU as an option for established buyers with existing customs infrastructure. ## Sourcing Guide ### Find Sourcing Agents - [Best Sourcing Agent in China: How to Find a Verified & Trusted Partner](https://snnp.com/faq/best-sourcing-agent-china/): A sourcing agent handles supplier vetting, negotiation, and quality control on your behalf.
