Marking & Labeling
Applying identifiers on packages for tracking, handling, and compliance purposes.
Definition
Marking and labeling ensures packages are correctly identified, handled safely, and meet legal and shipping requirements.
Overview of Marking & Labeling
Marking and labeling in logistics refers to the process of applying identifying information, handling instructions, compliance certifications, and tracking codes to packages, pallets, and products for the purpose of identification, tracking, regulatory compliance, and safe handling throughout the supply chain. Marking encompasses permanent or semi-permanent information applied to the outside of packaging — shipper and consignee addresses, country of origin, weight, lot numbers, and handling symbols (fragile, keep dry, this side up). Labeling refers to more structured, standardized label formats applied to packages and pallets, including GS1-128 barcodes (used for retail and B2B EDI compliance), SSCC pallet labels, carrier shipping labels, hazardous materials labels (DOT/IATA regulated), and date or lot code labels for traceability. Global trade compliance adds country-specific requirements: U.S. FDA product labeling, EU CE marking, California Prop 65 warnings, and FTC country-of-origin disclosures. In warehouse and 3PL operations, marking and labeling is a compliance-critical function that directly affects order accuracy, regulatory compliance, and retail compliance. Major retailers such as Walmart, Target, and Amazon have highly specific labeling requirements — GS1 barcode formats, pallet label placement, SSCC codes, case label formats — and failure to comply results in chargebacks that erode supplier margins. Hazmat labeling must comply with DOT regulations for ground transport and IATA DGR regulations for air freight, with non-compliant labels creating serious safety and regulatory risks. 3PLs managing labeling programs maintain label printers at every packing station, integrate with WMS for label data accuracy, and conduct regular compliance audits to verify label format and placement standards are being met. WareMatch helps brands find 3PL partners with proven labeling compliance capabilities, including experience with major retailer requirements and hazmat labeling regulations. By connecting merchants with 3PLs who invest in label compliance infrastructure and quality control, the platform reduces the risk of costly chargebacks and regulatory violations related to incorrect or missing labels.

Benefits
- GS1-compliant barcode labels enable automated scanning throughout retailer supply chains, reducing manual data entry errors and chargebacks.
- Standardized pallet and case labeling with SSCC codes enables full product traceability from manufacturing through consumer sale.
- Accurate hazmat labels ensure regulatory compliance with DOT and IATA requirements, protecting carriers and public safety.
- Country-of-origin marking compliance protects importers from customs penalties and ensures product eligibility for preferential trade agreement duty rates.
- Proper handling instruction labels (fragile, temperature, orientation) reduce product damage during warehouse handling and transportation.
- Automated label printing integrated with WMS ensures every package receives a complete, accurate label without manual transcription errors.
FAQs
Q: What are GS1-128 barcodes and when are they required?
A: GS1-128 (formerly known as UCC/EAN-128) is a barcode standard developed by GS1 for supply chain applications. It encodes structured data using application identifiers (AIs) — such as GTIN, lot number, expiration date, and SSCC — in a machine-readable barcode. GS1-128 labels are required by most major retailers and grocery chains for case and pallet shipments to comply with their supplier labeling standards. Brands shipping to Walmart, Target, Costco, Amazon FBA, and most national grocery chains must generate GS1-compliant labels from their WMS or ERP.
Q: What is an SSCC number and how is it used on pallet labels?
A: A Serial Shipping Container Code (SSCC) is an 18-digit GS1 number that uniquely identifies a logistics unit — typically a pallet — throughout the supply chain. The SSCC is encoded in a GS1-128 barcode on the pallet label and is transmitted via EDI (856 Advance Ship Notice) to the receiving party, allowing them to match the physical pallet to the electronic shipment record at their warehouse. SSCCs enable automated receiving with minimal manual scanning, reducing receiving labor and improving accuracy.
Q: What are the regulatory requirements for hazardous materials labeling?
A: Hazardous materials labeling requirements in the U.S. are governed by DOT Hazardous Materials Regulations (49 CFR) for ground and domestic air transport, and by IATA Dangerous Goods Regulations (DGR) for international air. Requirements include specific diamond-shaped class labels (flammable, corrosive, toxic, etc.), orientation arrows, UN identification numbers, proper shipping names, and packing group indicators. IMSBC Code governs bulk solid hazmat on ocean vessels; IMDG Code governs packaged hazmat on ocean vessels. Non-compliance can result in shipment refusal, fines, and criminal liability.
Q: How do 3PLs manage label compliance for brands shipping to multiple retail customers?
A: Experienced 3PLs maintain a label compliance library that documents the specific label requirements for each major retailer or trading partner — barcode format, placement measurements, required data fields, and font sizes. WMS systems are configured with retailer-specific label templates that auto-populate from the shipment record. Compliance coordinators conduct periodic spot-check audits comparing printed labels against retailer specification documents. When a retailer updates their requirements, the 3PL updates their template library before the effective date.
